the storage anarchist

4.010: when lightning strikes

There has been lots of discussion since EMC's announcement of VFCache, much of it about the implications of said announcement on the storage industry. I've seen all sorts of assertions made by analysts, competitors, wanna bees and prognosticators from all backgrounds – some thoughtful, some diversionary and some that are just down right silly.

There are those that say EMC's entry into the server-side Flash market validates the market for the early entrants. While that may be true in some regards, I will point out that when considered within the entire scope of the announcement, VFCache actually offers significant differentiation from would-be competitors. It is yet to be seen if or how the "established" players in server-side Flash market will respond to that differentiation. (More on this after the break).

There were some who turned this argument around – because VFCache was implemented as a "cache", it couldn't compete with the "established" players in this space – this even though VFCache offers the traditional "Flash-as-DAS" for those that want it. So then they said VFCache was too small to be competitive, especially since some of the other players were talking about 10TB devices and such. I found all this humorous – not surprising, just funny. I always get a chuckle when the success of something revolutionary is measured using the yardstick of the "old" way. Like when EMC introduced the first Flash drives for an enterprise storage array back in January 2008. There were a lot of people (and even a certain competitor's CTO) who asserted Flash was too expensive to have any real utility, and that "nobody was asking for it." Today, barely 4 years later it is hard to find any commercial mid-range or enterprise arrays that don't offer SSDs in ne capacity or another (pun intended).

Then there are those that assert this movement to server-side (Flash) storage represents a full circle return from the 20+ year external storage "diversion," portending the impending doom of the disk drive and/or the external storage array altogether. I assert that for either of these to be true requires an unforeseen discontinuity of pricing: solid state has to get a LOT cheaper than any reasonable projection, or hard disk drives have to get a LOT more expensive. Short of that, there remains a niche opportunity for flash-only solutions, but the sheer economics of $/GB will ensure that the vast majority of the storage market will be dominated by spinning rust for a VERY long time – though increasingly complimented by solid-state persistent storage to deliver the performance required by the typically small subset of any dataset that is "hot" at any given time.

And finally there are those that have made claims that server-side Flash is the precursor to entirely new ways of developing applications, fueled by the heretofore unattainable I/O performance levels delivered by affordable server-side large-scale solid state storage. Some of these pundits go on to assert that server-side solid state technology will drive such a revolutionary overhaul of application development that external storage itself will cease to exist. I personally believe these are fool's forecasts, proffered by those who ignore the reality of history. In the high-tech industry, new technologies rarely supplant the old – neither overnight, nor even over-decades. The IT landscape is littered with still-functioning dinosaurs that may well never be recoded or replaced: mainframes, tape, COBOL, SCSI, Ethernet, perl, , etc. Switching and conversion costs are formidable barriers to overcome. In a world where more than 2/3 of the average IT budget is spent just keeping things running, and the other 1/3 is being invested in storing the growing flood of new information in perhaps in a token few NEW applications to leverage it all, there is little opportunity to invest in rewriting anything. If it ain't broke, don't fix it. The more probable reality is that server-side Flash (like ever-cheaper DRAM) will lead to new ways of building file systems, databases and applications – BUT these will not represent an overnight revolution. Instead, this new “new” will follow the same evolutionary path as have the new technologies that have come before.

With that expression of my humble opinion, I'll spend the 2nd half of this post exploring how I see VFCache fitting into this information-centric world we live in…

4.004: vmax and vmaxe cameo appearances

Since its introduction in April 2009, VMAX has appeared in numerous television shows, news digests, movies and even Mayor Bloomberg's recent press conference announcing Gotham City's new centralized data centers. It seems that producers, directors and video reporters are attracted to the signature bold and blue facade that EMC's industrial design engineers created for the world's most Powerful, most Trusted and Smartest storage array.

You may have seen the following appearances (clockwise from top left):

• 24 (Fox)
• Nikita (CW Network)
• Covert Affairs (USA Network)
• Mayor Bloomberg's Press Conference on NYC's new City Agency data center
• 60 Minutes report on Speed Traders at NYSE

 

 

 

 

 

 

 

 

 

 

But wait! There's more!

4.003: a big thing in a small package

Imagine:

• Start with the world's most Powerful, Trusted and Smart enterprise storage array, hardened by almost 23 years of protecting the world's most critical information assets.
• Scale down its Intel-based infrastructure and dial-back its innovative scale-out architecture to optimize for less-demanding enterprise environments.
• Remove the layers of complexity associated with supporting legacy hosts such as mainframes and iSeries to simplify configuration and operations.
• Eliminate physical drive and RAID configuration altogether and pre-configure the array at the factory for pool-based Virtual Provisioning to radically simplify resource allocation and management while maximizing utilization efficiency.
• Allow customers to add factory-configured Fully Automated Storage Tiering (FAST VP) to further drive down the acquisition AND operational costs of both capacity AND performance.
• For local and remote data protection, include the world's most widely adopted heterogeneous Continuous Data Protection and Remote Replication capability, EMC RecoverPoint.
• Simplify the product installation to no more than a 4 hours to power-up, and 4 minutes to first I/O after the keys are handed over to the customer.
• Package that all in standard 19" racks configured to optimize floor tile utilization, requiring only single-phase power as evidence of reduced power requirements and deployment simplicity.
• Oh, and don't forget the trademark blue LED bar and one of those fancy little "e" thingies that the VNX guys introduced earlier this year.

What do you get?
 

4.002: Does page size matter -- a rebuttal

Hitachi Data System's CTO Hu Yoshida continues to try to defend the 42MB page size utilized by the Hitachi Dynamic Tiering (HDT) on the VSP. Apparently his first attempts to put lipstick on the pig didn't go over so well, so now he has resorted to good-old competitive FUD as he tries to convince his readers that the smaller granularity employed by VMAX FAST VP (7.5MB) delivers poorer "cost performance" than HDT.

Hu's basic premise is that the smaller the page size, the larger the amount of metadata that has to be maintained. He (incorrectly) asserts that VMAX FAST VP requires 54 times as much metadata than does VSP HDT. Further, he claims that managing and checking all that metadata requires 54 times more CPU cycles, reducing performance. He also makes a rather outlandish claim that the smaller page size requires 54 times more data movement.

With all due respect to Hu, his claims are total hogwash!
 

3.022: powerful, trusted and smart...meet dumb and dumber

So I posted back in January a two-part review of the key differentiating features and capabilities that make VMAX Fully Automated Storage Tiering for Virtual Pools (FAST VP) so much better than anything any competitor has put forth to date (or since, for that matter).

If you missed the posts, 3.018 is part 1 and 3.019 is part 2.

Oddly, I received nary a peep from either competitors or their customers about this post, which I found somewhat odd at the time (there was the one commenter who chastised me for being such a VMAX fanboi – sigh!).

Since those posts, I have had the opportunity to become better educated about the implementations of automated tiering from some competitors, including IBM (Easy Tier), Hitachi (Dynamic Tiering), and HP 3PAR (Adaptive Automation Optimization). Vendor documentation and best practices guides mostly, but I also gleaned some information from competitors' and independent blogs along with personal conversations with several with first-hand knowledge.

In my assessment, competitor silence in response to FAST VP simply underscores the assertion I made in those posts that VMAX FAST VP is in a class alone in comparison to those other products.

 

3.019: fast vp - world's smartest storage tiering (part 2)

In Part 1 of this article, I discussed how the new VMAX FAST VP is highly differentiated when it comes to implementation, architecture, algorithms and simplicity. In Part 2 I focus on differentiation in the granularity of data management and in the advanced controls for FAST VP.

Before I dive in, I also wanted to re-iterate that FAST VP is not the end-game for EMC’s investments in automated tiering. As we’ve said since we introduced the concept back in April 2009, EMC’s FAST Vision (and roadmap) is laid out in 5 stages, of which FAST VP is only the 2nd. Over the coming months and years, you will see EMC extend FAST in a progression:

1. Thick: VMAX FAST V1 provided policy-based optimization at the Full LUN level
2. Thin: VMAX FAST VP provides sub-LUN automated optimization
3. Small: Next up will be the incorporation of data reduction technologies to reduce the footprint of both idle and active data
4. Green: This phase will take efficiency to another level, moving idle data to spindle groups that will be automatically spun down until the data is actually needed
5. Gone: Finally, aged data blocks will be archived out of the VMAX itself to external archive platforms (like the one announced during the Record Breakers launch today)

So, in addition to the unique value propositions offered by The World’s Smartest Storage Tiering product, EMC’s larger vision is also highly differentiated. Although I do expect others will try to copy our vision as well…

On to Part 2!

 

3.018: fast vp - world's smartest storage tiering (part 1)

With the availability of VMAX Fully Automated Storage Tiering for Virtual Pools (FAST VP), there will undoubtedly be a raft of "we were first" and "me too" claims from competitors.

I will preemptively respond to both in this post.

As I've said many times before, being "first" in the market only really matters for as long as you are also "the only." As soon as there are more than one supplier of a feature, the discussion moves on to "which implementation is better."

I hereby assert than VMAX FAST VP is the smartest, most efficient, fastest,
easiest and most affordable sub-LUN automated tiering available in the market today
(and for the foreseeable future)

Second, I contend that no other vendors' automated tiering offering even comes close to VMAX FAST VP – and thus nobody has a basis for claiming "me too."

As I hope to explain, effective automated storage tiering requires much, much more than the basic ability to relocate data across tiers at a sub-LUN granularity. To even be considered as a contender, competitors will have to address three areas of FAST VP differentiation:

1. Effective Implementation
2. Granular Data Management
3. Advanced Controls

For each of these I will propose some questions the customers may want to consider when comparing implementations, along with the specific unique advantages offered by VMAX FAST VP.

I have split this post into two parts (it got a little longer than I planned).

Part 1 follows…

3.017: vmax 2011 edition - powerful. trusted. smartest.

In the 20 months since its launch back in April of 2009, VMAX has literally redefined the storage landscape. Back then, EMC focused the messaging around how VMAX was purpose-built for the virtual data center, leveraging multi-core Intel technology to deliver a highly efficient and scalable modular and tiered enterprise storage platform. We introduced the new Virtual Matrix architecture, the first array built upon that architecture, and the first wave of automation that has simplified the whole deployment model of Symmetrix storage.

EMC also did a bit of a Babe Ruth at that launch – pointing to the bleachers where we intended to deliver, in two phases, the innovation of Fully Automated Storage Tiering. FAST v1 for VMAX began shipping just about a year ago.

On December 15th, 2010 the second phase of FAST began shipping, along with more than 50 other significant features and new products in what we now call Enginuity 5875. Included also were some new hardware updates to VMAX – a new native 10Gb Ethernet director for SRDF and iSCSI, plus a new VMAX engine that sports an encrypting back-end to support Data at Rest Encryption.

Today (January 18th, 2010), EMC publicly announces what is inarguably the largest set of new storage products ever to be simultaneously introduced on one day. With over 40 new products and scores of new features, today's launch truly lives up to its Record Breaker theme. (If by chance you've missed all the hype, there's still time to learn about it at the #EMCBreaksRecords web site.)

So, what's all the hype about? Well, for the full effect, you'll have to go see for yourself. But within the context of VMAX, there's lots of new things in this latest release of Enginuity 5875, and I thought I'd lead off my contribution to the launch day communications with a quick run through of the major ones…

 

3.016: commodity vs. custom, hu cares?

Nigel Poulton has written a fair and insightful post over on his blog comparing EMC’s VMAX to Hitachi’s VSP. In it, he notes Hitachi’s use of not one but FIVE custom ASICs, as compared to VMAX’s single custom chip. He also (rightfully, IMHO) points out that it is likely these custom ASICs that caused Hitachi Japan to deliver VSP to market nearly 18 months later than VMAX, even though both use the same generation of Intel processor (quad-core Harperton) and the same first generation PCIe.

Even for a vertically-integrated company like Hitachi, ASICs take time – a LOT of time – to get right. Mess up one little thing, and you face months to respin the design and recast the die. And if you are doing low-latency memory I/O management, you face another respin each time the architecture changes; chips built for the PCIe gen 1 interface won’t work for PCIe gen 2 or 3, for example.

Hitachi’s Japanese engineering teams have invested heavily in the “hybrid” ASIC/Intel design for this “first generation” VSP. Maybe they had no choice – the USPV architecture doesn’t adapt well into Intel’s chip designs, where memory and CPU are tightly coupled, and not separated by a crossbar switch as is the foundation of the USP/USPV/VSP. By the way, I don’t think Hitachi’s architecture can survive long-term – in fact, I suspect that Hitachi Japan is hard at work right now re-architecting future VSP follow-ons to eliminate all the ASICs from their design. Looking at the designs of Intel’s next generation processors (Sandy Bridge/Ivy Bridge), they really have no other option.

This leaves Hitachi Data Systems’ marketing with no choice but to try to position the (temporary) use of ASICs as an advantage – even though it has already proven a significant time-to-market disadvantage. Japan has sent lemons, HDS has to make lemonade while they wait for the elves to finish redesigning their flagship enterprise array.

But back to Nigel’s post…

3.012: vplex geo preview at vmworld

Last year at VMworld, Chad Sakac previewed active/active application teleportation over synchronous distances using an at-that-time preview version of what we now know as VPLEX.

This year, Chad’s done it again – he’s sneaked an early look at how VPLEX Geo will enable active/active data access over asynchronous distances. He’s snagged an early (very early) code drop from the VPLEX development team and staged a demo that should at least start to silence the doubting Thomases among us.

Sure, it’s not live (nor is it Memorex ;-). Indeed VPLEX Geo isn’t even scheduled to ship until 1H’2011, and as Chad notes there is lots of integration work yet to be completed between the VMware and VPLEX development teams. But it is still an important demonstration of the potential VPLEX has to change the way we deploy our IT applications and infrastructure in the future.

So, without further ado, I invite you over to Chad’s Virtual Geek blog to see and learn about this preview for yourself: At VMworld? Try VPLEX. Like it? Take one home :-)

Oh, yeah – I almost forgot. VMworld attendees are being offered a special 90-Day Trial of VPLEX – just stop by the EMC Booth for more information!

3.001: my 18tb ipad 3g

OK, so I'm starting to see a faint glimmer of light at the end of the Get-Ready-For-EMC-World tunnel, as the content has to be nailed down pretty much solid tonight so that the hundreds of laptops can be pre-loaded for the week of sessions we'll be doing.

Whew!

For R&R between now and then, I thought I'd do a fun little post.

Soo…riddle me this:

Question: What does THIS

 

 

have to do with THAT?

 

 

Answer: I received a brand-spanking new Apple iPad 3G (64GB model, on the left) as a gift last Friday, and it is rapidly become my mobile desktop of choice. In fact, I'm almost convinced I'll do the entire EMC World without ever taking my laptop out of its case (I'm sure I'll not be the only one on that mission next week). I've already armed it with the productivity apps and presentations I'll need for my 1-on-1s, and things are looking pretty awesome.

On the right is the brand-spanking new Iomega ix12-300r SMB/Distributed Office rackmount storage array that Iomega announced yesterday. I am fortunate to have been a beta tester of the product for some (undisclosed amount of) time, and I must say, it is almost as exciting to the storage geek inside me as is the iPad to the personal-productivity geek that I am.
 

2.030: emc fast and the big 5

Proving the critics wrong once again, today EMC has announced the General Availability of FAST (Fully Automated Storage Tiering).

Perhaps unexpected is the fact that FAST is not only a Symmetrix V-Max feature, it is now available for all of EMC's block, file, and unified storage platforms. We actually told everyone that FAST would be cross-platform back in April 2009 when we announced it, but many seem to have forgotten until today.

Chuck Hollis, Mark Twomey and Gina Minks have collectively provided some pretty comprehensive insights on FAST – and more importantly, the new era of storage that it represents.

• Chuck Hollis: FAST and the Continuing Virtualization of Storage (Part 1, Part 2, Part 3)
• Storagezilla: FAST to the FULLEST
• Gina: EMC FAST – how do IT folks keep up to speed?

Also contributing to the social media buzz about FAST are numerous blogs and press articles covering today's announcement, plus a near-steady stream of Twitter chatter about "EMC FAST."

As for me, I've already discussed FAST in a couple of blog posts and comments since my first coverage on April 14th. Back in September I posted a FAST (Symmetrix v1 version) demo along with some Q&A from a "Tech Talk" I had done. Then in October I reprinted a fairly comprehensive review of why Hitachi's Tiered Storage Manager is anything but FAST, written by a well-respected TBC here at EMC.

So for now, I'll not do another dive into FAST, although I am actively answering questions today on Twitter @storageanarchy. There is plenty of accurate detail already available (just be on the lookout for the inevitable Competitor FUD).

Which reminds me: one thing I find amusing about today's launch is the supporting role that the competition and critics have played in the pre-publicity of today's FAST launch. Over the past several weeks, we've seen FAST critics, FAST wanna-bees and even wanna-be new product announcements, all in an obvious attempt to discredit, overshadow or perhaps even delay today's launch.

Though surely unintentional, all this buzz has pretty much had the opposite effect – if anything, all this activity has created even MORE interest in EMC's FAST offerings, not less. The customer value of centrally automated tiering inarguably will is changing the storage market, and EMC is clearly leading the way…as evidenced by IDC and Gartner's reports on the significant share gains that EMC has earned this year.

So, in the spirit of a recent competitor's Thanksgiving blog, let me say that I'm thankful for the predictable and expected spotlight on FAST that competitors have created for us. You have truly helped to broaden the audience for today's launch, and I sincerely I don't know how to thank you enough.

I hope you have enjoyed the pictures!

2.029: don't look back!

I’m just back from 2 weeks of holiday in South Africa, passing through home long enough to switch suitcases for my trip back across the Atlantic to Prague for Customer Council (I promise to post more pictures soon).

Up early to try and stay in the Czech Republic’s time zone during my brief stop-over, I noticed that self-proclaimed storage historian Claus Mikkelsen has leveraged a new report by his long-time compatriot and fellow Symmetrix-hater Josh Krischer to take yet another pass at bashing the Symmetrix architecture in his latest blog entitled Oh, the Commodity of it All!!

Of course I couldn’t just let that post go un-answered.

Follows an open letter response to Claus (and Josh). Normally, I would have posted this as a comment on Claus’ blog, but it appears I continue to be persona-non-grata on HDS blogs (excepting Michael Hay’s, who continues to respectfully engage…thanks Michael).
 

2.027: scale-out for virtual servers!

Earlier this week, Hu Yoshida wrote a blog post challenging the viability of scale-out storage architectures as a platform for virtual server compute platforms (such as VMware).

I can't sit on the sidelines and let that post go unanswered.

Hu is asserting that scale-out cannot support the Virtual Server world, but he makes no real case to back this assertion up. More importantly, it appears to me that he still doesn't understand how V-Max scale-out works.

What's more, his attacks on “modular” appear to be nothing more than an obvious attempt to defend Hitachi's “monolithic” architecture. And those of us with longer memories will recognize that Hu's position is in fact a 180-degree reversal of the position HDS took against Symmetrix for the last decade or so – Hu rarely missed an opportunity to beat EMC up for the fixed-cabinet “monolithic” storage of Symm 5 and DMX 1&2. Hitachi even had slides (and a few You-Tube videos) attacking the “Symmetrix monolith”.

And here Hu is today defending the very monolithic approach that HDS so aggressively challenged not so long ago.

 

2.024: stuck in the middle with hu

You've got to admit that the lyrics of the Stealer's Wheel hit have an uncanny resonance with the FCoE misinformation being promoted by
you-know-Hu.

I hereby refer my readership to

2.023: the future of flash is fast

I had the honor yesterday of hosting an EMC Investor Relations "Tech Talk" webcast on the subject of Flash Drives and EMC FAST (Fully Automated Storage Tiering).

Although Chris Mellor scooped me with his second-hand coverage of the event (Chris leveraged a report put out by Aaron Rakers to customers of Stifel Nicolaus Equity Research for his story), I thought I'd share the session with my readers first-hand.

So, if you have an hour or so, pop over to the IR landing page on EMC.com and click the banner link to the recorded webcast (or go directly to the webcast hosting site). But take notice – this webcast will be available on-line only through October 21, 2009.

I also included the net result of the FAST demo that Chad Sakac presented at VMworld 2009 in yesterday's presentation. If you'd like to see the complete demonstration, it's available on YouTube here:

I have also received a few follow-up questions from the event; I'll answer several of them after the break…
 

2.012: how to mind the future of a mission-critical world

A couple of weeks ago, in the midst of Hitachi's recent green eggs and HHAM announcement, HDS bloggers Claus Mikkelsen and Michael Hay teamed up to assert that I have nothing better to do with my time than to comment on their blogs. Michael even went so far as to comment:

Claus I agree with your approach here, and I do wonder if our Boy Wonder, Barry, is a full time blogger for EMC without anything else to do.

After that slap-in-the-face, both Claus and Michael have has chosen to censor my comments on their respective blogs his blog, and it appears that Christophe Bertrand will no longer publish my comments either. [UPDATE 21 June 2009: Although he obviously agreed with Claus’ decision to censor me, Michael now says he hasn’t received any of my comments on his blog- I’ll give him the benefit of the doubt – for now.]

Was it something I said? 

Fortunately, the storage anarchist does have a day job.

In fact, the latest issue of the EMC.now magazine includes an article about how the Symmetrix Product Group stays closely connected with the requirements and future vision of its customers and prospects, and provides some insight about what I really do here at EMC. If you're interested, the article is How to mind the future of a mission-critical world and it can be found on page 18 of the on-line version or on page 10 of the PDF version of the EMC.now magazine.

In fact, this close customer interaction that the Symmetrix management team maintains is the real reason why the words "from a unique perspective" is included in my blog's masthead. I get to see the future of storage technology through the eyes of customers dealing with the here and now.

Customer insight is also why I can ask EMC's competitors the tough questions so quickly and precisely whenever they make an announcement – I actually DO live and breathe customer requirements for storage, and it really IS part of my job to understand if, when and how competitors are addressing the customer requirements I learn about daily. So as irritating as my questions are, I know that the competitors are getting these same questions from their prospects. And their bloggers have come to know that  that I won't hesitate to call them out on a BS answer – especially when they make stuff up or misrepresent the facts.

And if that makes me persona non grata, so be it. Anarchy cannot be censored!

By the way, there are lots of other interesting articles in this issue of EMC.now. Whether you are an EMC customer, partner, prospect or competitor, I encourage you to give it a thorough read. And if you'd like to discuss any of the content, feel free to post your thoughts and questions here.

I promise you won't be censored, even if I might not be able to answer all of your questions.

 

This is another post from the storage anarchist.

2.010: pity the fool

V-Max sure has gotten under the skin of the HDS and their bloggers.

Not only has the pitiful HDS marketing machine rushed out yet another overhyped and underwhelming (green eggs and HAM) announcement, but every HDS blogger seems determined to take as many uninformed pot-shots of FUD at a product they clearly have not even yet begun to comprehend.

And it’s not just the bloggers who clearly don’t get it: a customer recently told me about some Hitachi marketing materials he has seen that attacked V-Max based entirely upon a Hitachi “suspicion” about the architectural utility of the Virtual Matrix. Seems based on that (mistaken) “suspicion” Hitachi’s conclusion is that V-Max simply cannot work. PERIOD.

When you don’t understand how something works, I guess all you CAN do is make sh*t up!

The latest blatantly uninformed attempt to discredit V-Max comes from HDS’ Christophe Bertrand as he delves deep into the FUD-bucket. In his latest post he tries to cast aspersions against V-Max while trying to deflect several of my very, shall-we-say, PESKY observations about the limitations of TSM – especially when it comes to relocating volumes that are being replicated.

Historically, Chris tends to mislead through incompletely reasoned logic and abject blind bias (I’ve suggested to him on more than one occasion that he is insulting the intelligence of his audience, but he still persists with his blissfully ignorant attacks). And he doesn’t fail to follow form with his latest…

In fact, it’s almost as if Christophe is Mr. T reincarnated (remember THOSE silly adverts?)!
 

2.002: meh – ibm really, really doesn't get flash

Someone sent me this today:

And I have been trying so hard not to be The Storage Antagonist ;-}

Word to the wise, though – if you don't understand something, don't blog about it as if you do.

I've tried to get IBM's Tony Pearson to understand this repeatedly over the years, and he just keeps making the same mistakes. Probably has him despising me as much as that other blogger with the same first name, because every time he slips up, I'm usually there to correct him before his misinformation gets any traction.

This week TonyP is trying to wax intelligent on Flash Drives for the DS8K, but in his attempts to discredit my previous post, he removes any lingering doubt that IBM doesn't "get" flash.

Be sure to take the time to read the comments, and you'll see that TonyP clearly didn't take the time to understand the STEC ZeusIOPS drive or its wear-leveling algorithms. As a result, he pretty much embarrasses himself and his employer (not to mention the IBM Distinguished Engineers he throws under the bus) in the process.

At least he didn't try to drag Master Scientist BarryW down with him!

So, knowing that TonyP wouldn't dare to actually do the math for his readers, I will…
 

2.001: ibm's amazing splash dance, part deux

A couple of month's ago, I posted a review of how the various storage vendors were embracing flash drives (or weren't, as the case may be). I then followed that up with a post lamenting the lame (and factually incorrect) white paper describing IBM's approach to enterprise flash drives.

I complained then that IBM was throwing cold water on a very key new technology; the fact that the errors in that white paper STILL haven't been corrected after nearly TWO MONTHS underscores my observation that IBM is totally out of touch with reality, and no longer the "trusted advisor" they once were.

(What happened, BarryW – I know you were working on getting those errors corrected!)

But today's news takes the cake: instead of doing it themselves (today IS IBM-Announcement-Tuesday, after all), IBM let STEC be the one to announce IBM's support for flash SSDs.

In my book, when you trivialize the importance of ANY technology to the point of having your supplier announce GA and availability rather than doing it yourself, it means something. And when IBM's sales force is to this day telling prospects that flash SSDs are "unproven technology" and "not ready for the enterprise," I can only conclude that IBM is embarrassed to admit some huge limitation or inadequacy of their products when used with Flash.

So, I asked myself…
 

1.063: vmware vsphere 4 to the power of v-max

Last month, Cisco UCS. Last week, EMC Symmetrix V-Max. This week VMware vSphere 4.

The virtual data center becomes real.

And if I may be so humble, more important to customers than the announcements themselves is the Day 1 integration between and across the products and companies.

Case in point: EMC has so many integration points with vSphere 4 that it takes two press releases to include everything:

• EMC Integrates with VMware vSphere 4 for Next-Generation Virtualized Data Centers
  Aligns Products, Solutions and Services with VMware vSphere 4 for Next-Gen Levels of IT Choice, Control and Flexibility
• EMC Delivers High Availability Path Management for VMware Vsphere 4 Data Centers
  New EMC PowerPath/VE Enables Customers to Improve Performance, and Simplify, Standardize and Automate Path Management Across Physical and Virtual Environments

Many of the V-Max ease-of-use features announced last week are targeted specifically for massive-scale vSphere environments, while things like the EMC Storage Viewer vCenter Plugin,   EMC's adapters for Site Recovery Manager, and now the new EMC PowerPath/VE work equally well with all of EMC's arrays, including both DMX and V-Max.

Chad Sakac, EMC's resident VMware evangelist-extraordinaire provides his take on today's announcements over on his Virtual Geek blog – I imagine he'll have more to say (he's the only storage blogger that writes longer articles than me, BTW – you were warned!).

Listening to the voice of the customer is good advice for us all…(be sure to read the comments):

techmute.com: Response to Tony’s V-Max Questions

 

Thanks, Matt – There's clearly room for improvement on EMC's communications to some audiences, but I think you received almost 100% of the intended message.

In answer to Matt's lingering uncertainty in questions 9 & 10 at the end of his 1st comment response to TonyA:

9. Being purpose-built for the its current (and future) functionality, rest assured that the performance of Symmetrix V-Max wide-striping and SRDF are not restricted by the Virtual Matrix Architecture…in fact, most customers will realize improvements to both relative to DMX4.
10. Best practices for Symmetrix V-Max were made available simultaneously with General Availability of the system. Although not radically different from DMX4 for existing features, best practices for new capabilities were developed and validated with the assistance of Beta Sites and in-house CSE expertise.

1.058: v-max does what hi-star can't?

This is the fifth in a series of posts on EMC's Overtake the future launch on 14 April 2009.

Taking a pause here from the launch to present an observation.

Remember how Hu Yoshida spent the first half of 2008 telling everyone who would listen that customers didn't need or want flash drives (if you missed it, I wrote about it here and there)? Hu was later silenced once Hitachi Japan announced that they actually would be selling the very same EFDs that EMC had been shipping since the beginning of 2008. (FWIW: Hitachi was supposed to ship the first of those drives in Q1'09, but I haven't been able to verify anyone receiving them).

Well, with the introduction of Symmetrix V-Max and the Virtual Matrix Architecture, it seems that EMC has once again done precisely what Hitachi's technical experts have been telling the world cannot be done. This time, however, I don't think Hitachi is going to be able to play follow the leader, since they're so mired in their backplane-limited Hitachi Universal Star Network crossbar switch architecture (formerly known simply as "Hi-Star").

Moreover, given their ever-increasing dependence on custom (expensive) ASICs, FPGAs and off-load engines, I predict it will be years before Hitachi's engineers can re-tool to leverage the price/performance curve of industry-standard components.

In support of these opinions, I offer the perspectives of none other than Hu Yoshida himself and fellow Hitachi blogger Michael Hay, in two separate and otherwise unrelated stories.

1.057: symmetrix v-max - scale up, scale out, scale away!

This is the fourth in a series of posts on EMC's Overtake the future launch on 14 April 2009.

Introducing the new Symmetrix V-Max^tm – the first enterprise storage platform to integrate the performance and efficiency of Scale-Up with the cost-effective flexibility of Scale-Out.

• Simple: Redefines enterprise storage architecture, ease-of-use and automation
• Scalable: start small, grow incrementally, supporting multiple tiers in a single array
• Cost-effective: more IOPS and more usable capacity per dollar (euro)
• Efficient: more IOPS and more usable GB per kilowatt
• Autonomic: Optimized for Fully Automated Storage Tiering across Flash, Fibre and SATA
• Compatible: Common management and SRDF interoperability with Symmetrix DMX
• Ready: Purpose-built for the Virtual Data Center

When you can list all those attributes for a single storage platform, you’ve made a statement.

Several years in development, today the new Symmetrix V-Max takes its place atop the world of external storage – right above the reigning #1 enterprise storage platform (according to IDC), the Symmetrix DMX4.

With its revolutionary scale-out Virtual Matrix Architecture, the Symmetrix V-Max literally redefines not only enterprise-class storage, but the entire storage landscape – because when an enterprise array offers the simplicity, performance, TCO, scale and flexibility previously found only in midrange offerings, you know you’ll change the world.

(By the way, BOTH Symmetrix DMX4 and Symmetrix V-Max are newer than either of IBM's and Hitachi's flagship enterprise arrays. It's like they're asleep at the wheel!)

And watch-out, you enterprise wanna-bees; V-Max has just raised the bar.

So, let’s take a look at the new king of the storage hill… 
 

1.056: inside the virtual matrix architecture

This is the third in a series of posts on EMC's Overtake the future launch on 14 April 2009.

The cornerstone of today’s Overtake the future launch is of course the new EMC Virtual Matrix Architecture, the foundation upon which the virtual data center will scale and thrive henceforth.

Combining the market-proven functionality that has made Symmetrix the World’s Most Trusted storage platform with the latest in industry standard compute and I/O technologies, the Virtual Matrix Architecture liberates the power of Symmetrix from the physical barriers of backplane-based monolithic storage arrays and redefines ease-of-use for storage in today’s increasingly virtualized data centers.

But while this new architecture is inarguably revolutionary in the world of storage, the Virtual Matrix is in fact borne of a Darwin-esque evolution of the same Symmetrix architecture that launched the external storage market over 18 years ago. The result is the first storage architecture that integrates the performance and efficiency of traditional scale-up architectures with the cost-effective flexibility of scale-out, blurring the distinction between modular vs. monolithic while redefining the scope of scalable enterprise storage.

In this post I will explain the path that has led EMC to The Virtual Matrix, and along the way I’ll highlight several of the key features of this revolutionary new architecture.

1.055: symmetrix v-max - a revolutionary evolution

This is the second in a series of posts on EMC's Overtake the future launch on 14 April 2009.

but first, a bit of nostalgia

For over 18 years, Symmetrix has been the very definition of enterprise storage - even as that definition itself has changed over time.

The first Symmetrix array was built as an alternative to expensive IBM mainframe storage at a time when data centers were largely still centralized and mainframe-based. In the mid-1990's, EMC added Open Systems support to Symmetrix, allowing a single array to support multiple different servers and bringing the cost-benefits of storage consolidation to a broader market.

Read on…

1.054: overtake the future - with symmetrix v-max!

This is the first in a series of posts covering EMC's Overtake the future launch on 14 April 2009.Updated on 16 April 2009 at 9:45 PM EDT 

1.051: skate to where the puck is going

I'm not an ice hockey fan, but I do know that skating to the puck is usually ineffective (and often embarrassing). As the great Wayne Gretzky explained, the winning strategy is to "Skate where the puck is going!"

Skating to where the puck is going is also a good business strategy.

As I've discussed over the past couple of weeks, when it comes to Enterprise Flash Drives and the storage array industry, EMC's competition is still chasing the puck.

Oh, sure, there are lots of visions of future capabilities being cast about by the competition. Promises of flash-as-cache, tighter application integration (often via proprietary lock-ins rather than open standards) and more efficient approaches to tiering – everyone seems hell-bent to publicly declare grand promises for tomorrow even as they belatedly (and begrudgingly) add support for 73GB and 146GB EFDs to their product lines today.

Well, guess what – they've missed the puck. Again.

With today's announcement of 200GB and 400GB Enterprise Flash Drives for the Symmetrix DMX4, EMC has once again netted a breakaway score (that's hockey talk). Through even tighter integration with the array hardware and software, these new 4Gb/s Fibre Channel EFDs are far more cost-effective on a $/GB basis than the significantly smaller drives that EMC's competitors are just now getting into the market.

And the fun thing is, I don't think anyone saw this coming this time, either!
 

1.050: e for efficiency

It started out innocently, with the introduction of the CLARiiON CX4:

Chronicles of Innovation: Energy Efficiency

Then you might say things got a little whacky.

Extreme Efficiency: Project Outdoor Office

Then folks got back to the very real ways EMC can help you save money – today...

1.049: would a "sixth sense" make us more rational?

Apologies for the off-topic diversion, but I can’t resist making a mashup of two topics I found this morning on TED.com.

If you don’t already know, TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader. Their annual conferences have been the platform for the initial introductions of some incredible inventions and ideas, and they have made hundreds of videos of earth-moving TEDtalks available to the public (their 400th TEDtalk was released today this week – you can get them ALL on your iPod here – apologies in advance, Martin).

If you don’t follow TED, you should. You’ll be amazed by the scope of the topics they present. (subscribe to their blog, podcast and vidcasts here).

The first subject to catch my eye was a teaser on TEDblog for Daniel Ariely’s talk this coming Monday night (16 March 2009) on the floor of the New York Stock Exchange. Daniel is the author of Predictably Irrational, my current audio book diversion (see more of my recommended audio book diversions here).

In this post, Dan offers 3 irrational lessons from the Bernie Madoff scandal. For those of you who haven’t read his book yet, Dan is a leading expert in behavioral economics, and his book explains a lot about how we work. For example, he discusses why we’ll drive 15 minutes out of our way to save $7.00 on a $25.00 pen, but won’t make that same diversion to save $7.00 on a $450.00 suit. The aforementioned Madoff essay highlights some of the overreactions he predicts we will make as a result of the disgusting Ponzie scheme, even if we weren’t personally caught in the trap.

But it was the second subject I found that inspired me to wonder if Dan’s observed human irrationality could be overcome…
 

1.047: dancin' with the starz

No, I'm not talking about The Woz's performance last night with Karina Smirnoff (although "A Teletubby going mad" was indeed an accurate description).

Nope, this is yet another follow-up to my flash dance / splash dance observations of the wild and sometimes whacky world of solid state storage.

Somebody has been taking dance lessons.

Or at least, they're paying attention.

Now appearing on the main stage: HP!

Yup, unlike IBM who seem to be totally unable to figure out the steps to this Flash SSD tango, HP has delivered a fairly coherent white paper outlining their perspective of Flash technology, entitled Solid State Disks for HP StorageWorks Arrays Whitepaper.

A welcome contrast to IBM's gloom-and-doom SSD white paper (the one that they still haven't figured out needs correcting).

I'll hasten to add that HP's paper represents a totally NEW perspective for the company – it was just a few weeks ago that the only thing SSD on HP's solid state landing page was about laptop and server applications. And after spending most of last year telling everyone that the technology wasn't ready for the enterprise and that it was being overhyped (by moi?), their solid state landing page has been recently updated to reflect a far more optimistic and comprehensive outlook for the technology. This is a most welcomed change of tune, because it will take the support of all of us in the storage industry to drive down the cost and expand the applicable use cases for solid-state technologies.

Welcome to the party, gents. You can stop trying to dance now, I guess.

But I do hope the Tucson Boys in Blue are paying attention.

1.044: ibm's amazing splash dance

Leave it to the folks over at Big Blue to throw cold water on the whole flash storage revolution.

On the same day that both IDC and Gartner confirmed that IBM is losing share in the external storage market while EMC is gaining, the following Tweet from "ibmstorage" floated across my TweetDeck:

IBM's approach to new storage technology
"Solid state disks for enterprise storage" http://tinyurl.com/acom2s (pdf)
ibmstorage , Fri 06 Mar 10:32 via web

The links gets you this white paper: Solid state disks for enterprise storage - IBM’s approach to new storage technology.

UPDATE: Just in case IBM moves or withdraws the referenced white paper, I have saved a copy of it here on my blog site.

With a title like that, I figured this paper would be the long-waited IBM response to my previous Flashdance post, even though it was probably at least in draft weeks before I started my post.

I wasn't to be disappointed.
 

1.043: the fine art of strategy

If you stopped by to engage in the latest round of storage blogger smackup, I'm sorry to disappoint.

Today's post is about "strategy."

Or, more honestly, it is about the right-brained approach to strategic thinking. As opposed to the analytical left-brained approach to strategic analysis that Michael E. Porter codified in his definitive works, Competitive Strategy and Competitive Advantage.

Why?

Well, first, because a recent commenter here on my blog accused me of "hiding" the fact that my job is in fact Chief Strategy Officer for EMC's Symmetrix Product Group. That accusation came with stinging indictments that I was intentionally misleading my readers by posing as an "independent storage analyst" while deriding competitor products and praising EMC's.

Those of you who know that i am anything but objective
can stop laughing now, before you hurt yourself.

I realize that while most of my readership is well aware that I live, breathe and bleed Symmetrix, not everyone does. Some of my more recent audience may not have taken the time to go back and review my earlier posts which pretty clearly define the platform from whence I pontificate. If you are one of those, I encourage you to enter the way-back machine and review my very first post, where I introduced myself and my context. And if you're interested, you can find all of my prior posts organized by date and categories in the archives.

As to the reader who accused me of hiding my identity, I will note that he actually contacted me by way of my Linked-In profile, which is plainly included in the sidebar on the right. I also include links to my About page, my Facebook profile and several on-line communities where you can learn more about me with a few clicks than you could have ever known about any trade journalist or industry analyst 10 years ago.

I am not attempting to hide anything; it's all there, in plain daylight.

The second reason for this post is in response to the myriad of people who ask me how I came to be a "strategist" and how they too might prepare for such a position. It's a question that used to be hard for me to answer, but I recently have begun to understand myself what it takes.

And I'd like to share a little of what I've learned…and how I learned it…

1.040: efd - what's in a name?

It seems that at least some of the Flash Dancers I called out in my last post are embarrassed to admit that their dance moves aren't all that awe-inspiring.

Other's seem intent on proving that they actually can't dance at all, like the Giraffes in Giles Andreae's book.

Or so it seems in the viral blogger war that's broken out over on one of NetApp's blogger's site (where else?).

At the root of the debate is EMC's use of the term "Enterprise Flash Drive," or EFD. Seems that representatives of at least two of the Flash Dancers (HP and, you-guessed-it, NetApp) have taken issue with this term, calling it a "new acronym" that proves that EMC "doesn't have a clue how to use flash technology at all."

This from a company that to date has delivered nothing flash-based to market other than a simple qualification of a third party solid-state storage device, and the as-yet-unfulfilled promise of a NAND-based PAM at some point in the future (as far as I can tell, they're only shipping DRAM-based PAMs to date).

Why am I not surprised? 

Because that's exactly what I meant about Flash Dancing – those that can't DO have to tap-dance around with competitor attacks and acrobatic misdirection to mask their inability to deliver.

But here's the thing – EMC didn't invent the term EFD as a marketing ploy. Nor did EMC bloggers all-of-a-sudden just start using it within the past couple of months.

No, the term has been used consistently since EMC's introduction of flash drive support back on January 14, 2008. In fact, my very first blog post on Flash drives described Enterprise Flash and EFDs.

Granted, that's before at least some of the anti-EMC attack squad were even participating in the blog-o-sphere, but that's hardly an excuse.

Given the confusion (and ruckus) that's spun up around the term, I thought I'd take a moment to explain what's behind EMC's intentional use of "EFD" instead of the more generic "SSD."
 

1.035: enterprise flash drives get wired!

Despite the fact that the Right Honorable Martin Glassborow (aka Storagebod) doesn't think EMC's first-to-market enterprise-ready flash drives are all that innovative, the folks over at Wired Magazine have included flash storage as one of their Top Technology Breakthroughs of 2008.
 

Coming in at a respectable #7 (and ahead of Flexible Displays, Edible Chips and Michael Phelp's Speedo LZR), Wired shares my optimism that most data centers will begin deploying enterprise-class flash storage for their most performance-demanding tiered storage applications in the coming year. Especially now that all the nay-sayers back in 1H08 now admit that they'll be shipping the same drives "soon" – including the previously vocal opponents over at Hitachi, HP, Pillar and 3PAR. (Sadly, IBM demonstrates its continued inability to even play catch-up in the storage technology space…let's not forget that IBM's official response to flash was to promote the increased use of TAPE!).

No, all the storage vendors who want to survive to see 2010 will be shipping and supporting flash drives in 2009, mark my words. And as Martin underscores in his post, the secret ingredient for both the Memristor and the flash drive will be the that leverages them .

Like many others, though, I question how the Apple App Store won out on Wired's Technology list…or even why the top 2 positions were awarded to personal communication device-related products. Personally, I'd say Mozy will have a bigger impact on the world than either the AppStore or the Android.

But then, I promised myself not to do one of those prediction posts this year.

UPDATE: I forgot to mention: Robin Harris apparently made no such promise – he ranks EFDs #3 in his 2008 Top Storage Products (like Martin, he picks Atmos in the top position).

Well, anyway, that's probably all I have for the remainder of the year. So…

Have a Happy New Year!

1.033: the end of the world

I found this little flash dittie whilst searching for clip art for this article, and I just couldn't resist posting it (warning - strong language):
 

attribution unknown

If you've been reading the storage blogs over the past couple of weeks, you might be inclined to believe that the end of the world is near. Especially if your world has anything to do with EMC - it seems like everyone lately is gleefully predicting the impending demise of EMC.

Why is everybody always picking on EMC!
 

1.030: flash as cache - really?

Over the past week or so, Robin Harris, Chuck Hollis and Stephen Foskett each discussed the "appropriate" use of flash technology going forward. Chuck comes down pretty solidly in the "best as persistent storage" camp, while Robin seems more aligned with FusionIO and the "flash as cache" side of the argument, while Stephen seems content to accept that flash will appear at both the initiator and the target sides of the I/O conversation.

I myself tend to agree with Stephen.

BUT!

(You know there's always a BUT! with me).

A few things have been nagging at me about this whole flash-as-cache discourse. The first is centered around the fact that it takes longer to WRITE a block to NAND flash than it does to READ it.

Unlike traditional SDRAM where reads and writes complete at the same speed, with NAND even if your flash controller is smart enough to asynchronously pre-erase blocks, it still takes longer to perform a write than a read. And if you take the time to verify the accuracy of the write, it gets even worse.

So my question is, since it takes longer to write than to read a NAND block, and every read hit required at least one prior write:

What read hit ratios and repetitive reads of a block
are required to overcome the NAND write penalty?

inquiring minds want to know...

1.029: atmos. with, and without, the sphere

I'm just back from vacation cruising several Italian, French and Spanish ports aboard the Wind Star on the Mediterranean with my wife. It was a relaxing, multi-cultural Adventures Afloat trip arranged by her employer (Elderhostel), a not-for-profit who specialize in educational travel and learning opportunities. With a foundational belief that learning is an integral part of a healthy and fulfilling life, the organization offers its unique Adventures in Lifelong Learning to anyone who is interested - at an exceptional value! So, if you're looking for a travel programme with more than just the usual tourist trap visits, I encourage you to visit their web site and/or order their free catalog.

Oh, and don't let the name fool you: participation is quite diverse, and you'd better be in good shape or you might just get left behind.

Anyway, being on such a trip with my wife, I wisely avoided all things work for the duration.

Preserving the atmosphere, you might say.

But so much has gone on in the past couple of weeks, I thought I'd take a stab at connecting some of the key sights from my cruise with a few of the more interesting events of the past week or so.

So let's have a little fun. Shall we?
 

1.025: flash wars and the great debate

No, I'm not talking about the on-again US presidential debates scheduled for tonight in at Ole Miss.

Nor the decades-long debate over whether Nikon or Canon make the best intelligent TTL flashes for their cameras. (I choose Canon).

I'm referring to the ongoing debate about where NAND Flash should be used - server, network or storage.

It seems that everywhere I turn I find proponents arguing about where the technology is "best utilized." And like the presidential debates, the positions tend to fall along party lines: server vendors and their suppliers insist you can't get everything NAND has to offer unless you install in right next to the server CPU, ideally with a native memory bus or I/O bus (e.g. PCI/x) interface; the external storage vendors and their supply chain insist that the disk drive form factor and interface is best; and of course the network storage appliance world insists that NAND belongs as a service in the middle.

And they're all correct.

That's right - while EMC and I are both proponents of using persistent solid state storage as a faster alternative to spinning rust, I personally believe that there is no reason the technology won't be applied at every layer - and probably in multiple places along the same I/O path!

In support of my postulate, look no further than all the rest of computing technology - CPU's, DDR SDRAM, spinning disks, PCI/x, protocols, interfaces, connectivity, etc...every single component - both hardware and software - is today applied in servers, and in networks, and in external storage. We put DDR SDRAM and/or processing power into external storage devices and connect servers to them using Fibre Channel, and we also build servers with terabytes of addressable local memory - both approaches can accelerate existing applications without requiring applications to be re-architected or redesigned.

Is there any reason to believe that NAND (or any solid state storage technology) should be applied any differently?

I think not.

So why the continuing debate?

 

1.013: more on enterprise flash

Sometimes I just can't keep my opinions to myself.

Last Friday afternoon while I was perusing Chris Mellor's Blocks and Files, I was struck by the discontinuity of messaging that is emerging around the "best" application of Flash drives. From the "flash can't write fast enough" doom and gloom of the relatively unknown wanna-bee Infortrend to the "flash is too fast for external storage" justification for Sun's focus on server-based flash, it struck me that uninformed readers were likely being confused, if not outright mislead by the contradictory misinformation.

So I dashed a letter off to Chris outlining my concerns and rebutting the misrepresentations of the real benefits that the right flash drive is already delivering today - despite the unfounded claims of others in the storage and server industries. And upon his request, I granted him permission to publish this as an opinion piece on Blocks and Files, which he has done under the title of Missing the flash point (a fitting play on words, IMHO).

N.B. - Normally, I would have posted this to my own blog, but part of my concern is that the misleading information is being distributed by sites like Blocks and Files. My letter was in fact originally written in a context beseeching Chris to present a more balanced perspective on the realities of flash technology. When he offered to publish my opinion outright, I figured the best way to provide balance was to use the same billboard, so to speak.

Anyway, I hope that my opinion letter helps expand the conversation about flash technology. In my opinion, there's nothing to be gained by trying to polarize this into an either-or discussion. In fact, I honestly believe that there are appropriate applications for Flash-based storage in both servers and external storage arrays. And judging by the applications I've seen flash targeted for by customers, the early adopters are going to have a pretty big competitive advantage on their competitors.

The bottom line is this - the sooner that more vendors stop quibbling over who, how or where flash is "best" and actually start bringing real flash technology to market in their respective products, the sooner (and faster) we collectively will drive up demand and drive down the costs.

And that, my friends, is the whole point...the flash point, as it were: leveraging Flash to cost-effectively bypass the inherent limitations of mechanical disk drives...

IMHO

1.012: flash drives in enterprise storage

Yesterday I presented a webcast on Enterprise Flash Drives to EMC's investment community, as part of Investor Relations' ongoing Tech Talk series. If you'd like to see it, the slides and replay are available on EMC.com here: Tech Talk for Investors: Flash Drives in Enterprise Storage, but only until July 25, 2008.

Chris Mellor has also reported about this presentation over on Blocks and Files in his "EMC on enterprise flash drives" analysis piece. (Thanks for noticing, Chris - glad you were able to participate).

On a related topic, Network World's Jon Brodkin takes a look into the growing market demand for Flash technology in his article titled Flash storage gets enterprise attention as prices decline. The article provides a fairly comprehensive look at what's going on in the realm of enterprise flash across both storage and server vendors, and it is definitely worth the read.

But I have to admit I was kinda surprised by this quote that Jon included from Michael Workman, president and CEO of Pillar Data Systems:

"The best use of solid-state disk is direct-attached, not in a shared network array. The reason for that is the latencies for solid-state disk are so low that putting it on a network to get at it actually makes the latency of the solid-state disk much worse than it could be."

IMHO, that's a pretty uninformed position to take, especially by the chief executive of an external storage vendor.
 

1.010: sun adds critical mass to flash

Please join me in welcoming the latest member of the "we too will be delivering flash technology someday soon" consortium - the farm club for the "we are ALREADY shipping enterprise flash technology" league (of which EMC is the only current member).

Not to be outflanked by IBM, nor pigeon-holed by Hitachi's slow uptake of the technology, Sun Microsystems this week jumped aboard the NAND flash bandwagon with guns a-blazin'. They say they're going to put flash everywhere - in the server, in the storage, as primary storage, as intermediate cache, using both SLC and MLC dependent upon use case - you name it, they're going to do it.

And what's more, according to Sun:

"By the Christmas holidays, anyone with an I/O performance intensive application is going to be trying to find a way to get [SSDs] into their systems."

(And to think, just last week, people were quoting Gartner and challenging both Joe Tucci and Dave Donatelli for being too optimistic at EMC World about the uptake of flash.)

OK. Clearly, we've entered the hype phase of enterprise flash storage. And it is inevitable that we live through this hype - necessary, even...every new technology has to navigate the curve, cross the trough of disillusionment, and leap across the chasm before it can reach mass adoption. And with flash storage in the enterprise space, we're just getting started, so you know that there will be plenty more exuberant hyperbole to come.

Rather than deride it, we should welcome the hype of the newcomers with open arms, because every new supporter reinforces the viability of the technology and accelerates us further down the adoption curve.

I just wish the newcomers would bring a little more specificity to the picture.

Don't you?
 

1.008: emc world 2008 - the follow up begins

Most of us have managed to find our way home from Sin City, and now we deal with the rapid decompression as we reenter the atmosphere of EMC World, the Work Edition.

Thankfully, those of us who are US-based had the extra 24-hours afforded by the Memorial Day holiday.

Lots was learned at EMC World, both by our customers and by the EMC developers that ran nearly 100% of the sessions. For customers, future IT strategies will be tuned to better leverage the current and future technologies; and for development, a better understanding of customer requirements and use cases will serve to refine the future products and implementations. Enabling and leveraging this symbiotic relationship between supplier and consumer is the foundation of what EMC World is all about.

If this was your first EMC World, I'm sure you were overwhelmed by both the breadth of topics and the unfettered access to the people who create these products.

And if you've never been to an EMC World (aka Wizards, aka Tech Summit), then you're probably wondering what all the hype has been about.

I'll use the words of a customer to explain...

 

1.006: enterprise flash: when speed is what you need

I wish I had come up with that title for the presentation I'm about to give here at EMC World, but I didn't. Instead my session has the awe-inspiring title of "Performance Best Practices: Symmetrix Flash Drives."

Network World gets the credit for the title of this post. It is actually the headline for the podcast interview that I did with them on the differentiation and benefits of the new Enterprise Flash Drives that EMC has been shipping for the Symmetrix DMX-4 since Q1'2008.

Gotta admit the timing of this podcast is interesting, though. Not only am I presenting a superset of this discussion at EMC World today, but this morning Hitachi did a 180 on their prior nonchalance over flash technology That's right, despite HHSNBN's repeated public denials that there is any reason for anyone to need flash drives, Hitachi today announced that they indeed did intend to announce something about adding some kind of flash drives from one or more unspecified vendors in an unknown capacity point  (or points) with undefined performance and reliability to their storage lineup sometime late in Q4 (whether calendar or fiscal Q4 was apparently not mentioned).

Gotta love the specificity!

I hope to post more on both topics later this week (both my EMC World flash presentation and Hitachi's latest attempt-to-catch-up-and-stop-the-bleeding announcement)

For now, here's the link my enterprise flash interview on  Network World Panorama.

Enjoy!

0.078: lions and tigers and bears!

Driving in to work today, I heard a news report about the Hollywood Grizzly Bear that killed his trainer yesterday.

When I got to the office, I listened to Joe field questions during EMC's earnings call (19 consecutive quarters of double-digit year-over-year revenue growth). Several of the participating financial analysts inquired about the potential impact that the newly-delivered virtual provisioning for Symmetrix might have on future capacity demands. From the tone of the questions, you could easily imagine a pride of lions circling their prey.

And sure enough, by noon Beth Pariseau had her coverage posted on SearchStorage, under the headline EMC's Tucci: Thin provisioning mandatory but overrated.

Shortly after the earnings call, a colleague forwarded me the link to a Byte and Switch article by Mary Jander entitled Your Storage Arrays May Be Dangerous. In this article, Mary decries that people need to "rethink the environmental impact of storage gear," because the EPA has reported that electricity use for storage is growing faster than the energy used for the data center overall. Not surprisingly, the EPA called for "storage virtualization, data deduplication, storage tiering, and movement of archival data to storage devices that can be powered down when not in use" as strategies for avoiding environmental damage if not disaster.

Oh my!

In fulfilling my promise to get back to blogging about technology, I thought I'd invest today's post to provide a slightly less sensationalist perspective on thin provisioning, storage capacity and energy efficiency.

And all I have to say about the bear is: remember, these are wild animals, and they're driven by instinct and not logic or trust.

Any resemblance between wild animals and industry experts is purely coincidental!

 

0.076: oops!... i(bm) did it again!

I know that many of you are getting tired of me pointing out the frequent faux-pas made by competitor's executives. To you, I apologize in advance for today's post, and I'll understand completely if you skip this entry or unsubscribe from my feed in protest.

Especially those of you from IBM, on both sides of the pond. I seem to get more hits from the ibm.com domain on these articles than from anywhere else!

I am sincerely trying to stop, honest I am. But just I can't. At least not until these guys stop feeding me material.
 

Before I continue, though...a note about today's theme.

About a year ago, when I was first thinking of starting up this blog, Chuck Hollis told me one of his super-secret tricks for attracting hits to his blog. He said he would include "Britney Spears" as one of the keywords for every one of his posts, and that he'd get a sizable percentage of hits from search engines like Google and Yahoo! as a result. Not that I need the hits, but the song title fits my topic, so I figured I might try it to see what happens.

So, if you're a Britney fan who accidentally got lured here by this little ploy, my apologies to you as well. This probably isn't what you were looking for.

But if you're both a storage geek and a Britney fan - Welcome! You'll probably recognize the subtitles below...

 

0.073: 5773 > c

In case you've been wondering, the previously announced Q1'08 Symmetrix enhancements, including Enginuity 5773, the 73GB and 146GB enterprise flash drives, the 1 TB SATA-II drive and the new GigE I/O director all shipped on schedule last week. As usual, there's quite a bit to talk about, because in addition to what has been announced already, there are several additional features in this code release that revenue recognition rules prohibited EMC from disclosing until everyone was confident that they would actually make the GA release in Q1.

But discussion of perhaps the most significant new feature in 5773 was held back for another reason: to get all the patent applications filed before it was disclosed. This one new feature could well prove to be the foundation of a whole new era in remote replication - potentially changing the nature of distance replication more than flash drives will change the storage media end of the equation.

But it'll take a little explaining (hint: it has something to do with the title of this post), so before I get into the details, a little background...
 

0.071: changes in latitudes, changes in attitudes

I took off for a week-long sojourn to the Conch Republic [history] last week, where I celebrated the half-century mark of my life with friends and family on St. Patrick's Day .

It couldn't have been better - from the boat drinks by the pool and the strolls down Duval St. in the unseasonably warm (and humid) weather, to an afternoon listening to Michael McCloud and sucking down Land Shark lager at Schooner Wharf, to the tours of the homes of Hemingway, Truman, Audubon and more butterflies than you can possibly imagine, to watching some of the most picturesque sunsets I've ever seen from Mallory Square and Fort Taylor State Park. And then there were the dinners at Louie's Backyard, Blue Heaven (in the company of chickens), Salute' and El Siboney (twice!). Not to mention the night life! [link intentionally omitted ]

Yes, Key West is a great place to turn 50, even if you're NOT a pirate (did I mention that it was Spring Break?)

Amazingly, and even though I did bring my laptop, I was able to resist the temptation to respond to the storage news of the week. With all the R&R I was enjoying in Margaritaville, it was a struggle to keep my fingers off the keyboard (NOT!).

Something about the weather just made it all seem so...unimportant!

But trust me, the week's events didn't go by without notice...
 

0.070: horton hears a hu

My sides hurt.

I ended last week rotflmao!, thanks to IBM's Charlie Andrews and his creative response to flash-based solid state storage (tape, he said...TAPE!). At the time, I figured that nobody could top that for the flat-out wackiest statement of the year.

Apparently, I underestimated Hu Yoshida.

Not content with his first round of uninformed comments about flash SSDs, HDS' so-called "chief technology officer" piled on a few more layers of baloney in an interview with IT Week UK's Dave Bailey:

IT Week:

What are your views on Flash memory storage, which EMC recently announced it would be putting onto its DMX systems?

Hu:

There are a number of problems with Flash memory. First, the price, which can be up to 20 times as much as spinning disks. Secondly, there’s supplier viability – there’s only a few vendors of this technology at the minute. You’ve also got to remember that Flash disks have a rewrite limitation and we need to have some diagnostics to predict when that limit could occur. For hard disks, we have self-monitoring analysis and reporting technology (Smart), but there’s nothing like that for Flash disks. What happens if you’re in the middle of a financial transaction and a write failure occurs, after a write commit? As for performance, just because it’s solid state doesn’t mean it would be any faster than a spinning disk. Remember all those interfaces between your application and the disk are slowing the data transfer rates, so it would be a good idea to benchmark your set-up.

What happens on a write failure, he asks?

LSHIPMP!

OK, well, I almost PMP...

Wait, let me catch my breath...

Come on, he can't be serious...I mean, it's not like disk drives don't suffer from the occasional write failure, yet somehow we manage not to lose data. At least, EMC arrays manage not to lose data - with multiple layers of protection and recovery.

Can it be that Hu is really that out of touch with reality?
