1.015: stranger danger

If you have children, hopefully you've taught them about Stranger Danger at a very young age - prevention and awareness are the most powerful weapons we have to protect our families and friends.

And if Symmetrix DMX could talk, it surely would be yelling at the top of it's blower fans:

NO! I don't know you! You are not my Dad!

Let it hereby be known that Moshe Yanai is not the father of Symmetrix DMX.

No, despite the public assertions of IBM to the contrary, Moshe had virtually nothing to do with the creation of Symmetrix DMX. And on behalf of the hard-working, dedicated engineers, developers and patent-holders who did in fact design and deliver DMX to the market in February of 2003, it is high time to set the record straight.

Moshe's responsibilities for Symmetrix development ended in 2001, long before DMX production even began. And Symmetrix DMX was a radical change in virtually every dimension from the 5 generations of Symmetrix that preceded it under Moshe's watch.

I'm pretty sure Moshe didn't like anything very much about Symmetrix DMX.

And I will point out that Moshe left EMC in 2002 (for whatever reason), which was well before DMX was even introduced to beta sites or discussed under NDA with analysts and prospects.

I was the marketing lead for the launch of Symmetrix DMX, so I know first-hand that he wasn't involved.

So, as you can imagine, I find it curious that IBM is attempting to mislead everyone who will listen that the success of DMX is a feather in Moshe's cap - evidence of his storage prowess and foresight.

On behalf of DMX I say: thanks for the recognition as the market leader. But he still ain't my dad!
 

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.
 

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!

 

0.074: emc world 2008

EMC World 2008 is just about a month and a half away, and the preparation  activity around the office is really picking up. Presentation content is being reviewed and critiqued, the kinks are getting worked out of the hands-on workshops and show-floor challenges, the chatchkies and prizes are starting to come in, and everyone's travel arrangements are being buttoned up.

And now that Q1 is complete (and 5773 is shipping), the excitement will really start building, hopefully to crescendo May 19-22 in Las Vegas.

A couple of weeks ago, I recorded a "teaser" for my session on Flash Drive performance and best practices. Mostly, the teaser is just the marketing side of the story. In my session I'll actually be diving into details on the performance customers can expect to attain for different workloads, as well as discussing the various tools that can be used to identify applications (or parts of applications) that could benefit most from sub-millisecond response times that Enterprise Flash Drives deliver on Symmetrix.

0.068: rotflmao!

And I almost couldn't get back up...

Regular readers know that I've been predicting the market exit of the DS8000 for most of my tenure in the blogsophere. As can be expected, this has attracted the ire of IBM bloggers, who routinely dismiss my observations as misinformed FUD. I've even been called "silly" by members of the IBM blogging corps.

So perhaps you'll understand why I was laughing hysterically after reading comments made by Charlie Andrews, IBM's marketing director of storage systems, in Beth Pariseau's recent SearchStorage article (see IBM: Thin provisioning on the way for DS8000).

According to Charlie, the DS8000 is indeed still being updated, although apparently only to support IBM's newest mainframe monopoly models. Some neat stuff - like larger volumes and granular fail-over (welcome to the 21st century, zSeries!).

But when I read Charlie's responses to Beth's inquiries about the increasingly long list of features missing from the DS8000, I literally fell out of my chair laughing.

Not almost - I actually hit the floor. LMAO

Read on to learn why...

0.067: revenge of the mainframe

Hot on the heels of the raging debate between Chuck and TonyP over who's really leading the Open Systems Disk Library market, EMC this week announced its newest EMC Disk Library for Mainframe. Now, in my mind, the press release is improperly titled, in that it positioned the EDLm (as we affectionately call it) as a "Virtual Tape Library" - but unlike traditional VTLs, the EDLm is tapeless!

That's right - it is 100% made up of SATA disk storage, transparently managed behind zSeries-compatible FICON- or ESCON-attached tape emulation engines, with the performance and bandwidth to support backup/restore, batch "tapeless" processing, and/or nearline storage - all in a single, integrated package. Already there are several pilot/beta sites, and general availability will begin in March 2008.

Marketing used this week's SHARE Conference down in Orlando as the venue for this announcement, and they even crafted this video-mercial for the event (and no, it's not Bob & Joe this time):

 
Revenge of the Mainframe

For those interested in learning more about the EMC Disk Library for Mainframe, as well as EMC's other mainframe storage solutions, stop by the Ready2Rule landing page on emc.com.

And there's now a whole EMC channel on YouTube, where you can find a lot of "video white papers" on EMC solutions (in addition to more funny videos - check out the Celerra NS20 Installation SMACKDOWN for one of the better ones).

And for the record, if you are in the market for cost-effective SATA storage for your zSeries, whether for bulk storage, near-line, compliance retention or even on-line applications, EMC is ready, willing and able to help you fulfill those needs...today!

0.061: swinging from the sidelines

He Hu Shall Not Be Named has returned from his vacation in Aloha-land to learn that EMC has announced something of which he knows nothing about. Predictably, he has wasted no time demonstrating his total lack of knowledge about enterprise flash drives in his latest blog post.

Makes me wonder what the "CTO of Hitachi Data Systems" really does, since he obviously isn't following emerging new storage technologies all that closely.

Nor did he even take the time to do any research before posting, choosing instead to throw wildly uninformed punches at the technology in an attempt to defend Hitachi being caught flat-footed.

Not surprisingly, HHSNBN even manages to drag virtualization into the discussion. Now, is it just me, or does it seems like he can't write a post without using the V-word? I'm beginning to think he must use a customized version of the Ergonomic Keyboard for Pirates that has been making the rounds of late (pictured at right). On his version, though, the "Avast" key types "Virtualization."

<Shift>VIRTUALIZATION<Space>RRRR<shift>!!!<Enter>

Swinging from the sidelines

Clearly lacking a relevant clue about the the technology (and unable to buy a vowel), HHSNBN alleges that anything NAND can do, DRAM can do better and faster. Which is true, I guess, if you include consuming your IT budget in that comparison. Because as expensive as SLC NAND flash is today, it's already an order of magnitude or two cheaper than high-performance DDR2 SDRAM. Must be that Hitachi Math thing again.

So I'll just tack that one on the bulletin board right alongside "Intermixing, slower, less reliable SATA or FATA disks in tier 1 storage systems will impact that system’s performance and availability", which was HHSNBN's excuse for not supporting SATA in the USP. Right up until Hitachi Japan added SATA support to the USP-V at the end of last year, that is.

Some words of advice seem appropriate here:

It is far better to remain silent and be thought a fool
than to speak out and remove all doubt.

(the debate rages over who actually said this first)

the truth about enterprise flash drives

For the record, the enterprise flash drives that EMC announced last week are not the same as the consumer flash drives that is going into Airbooks, laptops and IBM blade servers. And they won't silently lose data (they'd be pretty useless if they did) - like disk drives they remap suspected bad blocks before they cause a problem. They'll probably outlive the practical life of the storage array before they wear out - the nominal operating life of SLC NAND flash typically far exceeds the rated minimal 100,000 writes per cell, and when you add in wear leveling across nearly 2x extra capacity within the drive, they will outlive all but the pathological 100% write forever use case.

Yes, enterprise flash drives use SDRAM buffers to accelerate writes, with both internal and Symmetrix-supplied backup power to protect that memory against unexpected loss of power, be it momentary or an extended outage. They are shielded from electrical and mechanical interference in a disk-drive form factor. And they do indeed provide extensive status reporting (basically the Fibre Channel & SCSI equivalent of S.M.A.R.T.), affording the array the ability to be proactive in protecting customer data.

And you don't have to take my word on that.

Thankfully, the folks over at Wikibon have taken a much more thoughtful approach at evaluating last week's Symmetrix announcements. After what was obviously a lot of actual research, they today presented a comprehensive review of enterprise-class flash drives, the customer benefits they can deliver and the practical implications that they will likely have on the entire storage industry over the coming years. I encourage you to read and comment on their review.

Oh - it's aptly titled EMC Lands a Haymaker.

0.060: blinded by the light

For those of you who were so breath-taken by EMC's unexpected "viper on steroids" lightning strike with Enterprise Flash SSDs, here's my perspective on the rest of Monday's Symmetrix announcements:

They were pretty neat, too, although clearly not as
revolutionary
as the enterprise-class flash drives will be.

And so, before I dig into the rest of the neat that was announced, you gotta admit - it is truly exhilarating to be totally surprised with the announcement of a disruptive technology that could very well supercede the performance, power (and hopefully the cost) limitations of spinning disk drives!

Of course, the competition has responded with the expected aplomb. Hitachi has gone on record with the assertion that this is all an uninteresting niche play limited to the needs of the Fortune 50 . Meanwhile, IBM's designated storage blogger is gleefully cheering from the sidelines that EMC is retreating to its roots in solid-state storage.

Methinks perhaps they've been blinded by the flash (if not outright  blind-sided).

From my perspective, the roots of the so-called EMC Specialty Shop aren't in solid-state storage at all, but rather they are entwined with a proven track record of out-innovating competitors in the storage space for nearly 3 decades. You need only look at EMC's Innovation Timeline to see the legacy of being the first to deliver solutions to very real and broad-based customer problems over that timeframe - from RAID to ICDA to SRDF to DMX and now flash drives.

Even IBM's recent XIV acquisition is an admission of that fact, coming months after Joe Tucci let the world know that EMC had set its sights on the cloud storage market with the impending Hulk & Maui products. And given that it is likely to be at least a year before the IBM Blue logo goes on the Nextra box and it gets into the bags of IBM's mainstream sales machine, I suspect that Hulk/Maui will technically beat IBM into that market as well.

That said, rest assured that neither IBM nor Hitachi are internally treating enterprise-ready flash drives as another Al Capone's vault. Inside they all (now) know that enterprise flash drives are very real, that they serve a very real and current customer problem, that they will inevitably change the way we think about storage in the future, and that they need scramble to catch up to the lead that EMC has established. They're not really stoopid - they'll be trying to get into the game as quickly as they can.

And while today's enterprise-flash drive benefits may primarily be their incredibly fast response times and energy-efficient IOPS/watt, we all know that customer demand and cost erosion will rapidly expand the market. The future of flash-based storage is inarguably ahead of us.

As to why TonyP would try (in his blog) to compare the 73GB & 146GB enterprise flash drives that EMC just announced to the new "larger" 31.5GB (and 10x slower) consumer-grade flash drives that IBM just announced this week for their blade servers (the drives that come with only a one-year, limited warranty) ?

I honestly haven't a clue.

 
OK - enough of that fun. On with the new Symmetrix stuff...as usual, there's lots to talk about! 
 

0.059: bold, fast and green

No, I'm not talking about Kermit the Frog or a souped-up Kawasaki.

Nope, I'm talking about EMC's introduction today of Flash Solid-State Drives for Symmetrix DMX-4 - the first-and-only enterprise-class application of Flash technology.

Now, if you've already read Chuck's blog post (The Enterprise Strikes Back) and Mark's early-morning coverage (Enterprise Flash for DMX-4), you should have a pretty good understanding of who needs these things and why, and on the technology itself. No need for me to rehash that ground. And even Stephen-the-Packrat has noticed that What's Old is New Again, reinforcing the significant differences from these enterprise-flash drives and the stuff that Apple slaps into its iProducts. Oh, and here's the obligatory link to the original WSJ "scoop" on today's news.

Since I have had a front-row seat to the accelerated evolution of this technology into what today is a truly enterprise-ready solid-state storage solution, I thought I'd share a little about the journey that has brought us to this point.

Sorry for the delayed posting. I've been technical reference support for the SSD part of today's launch, which kept me pretty busy all day. Judging by the nature of the questions and the early coverage, this Flash thing seems pretty hot (pardon the pun). I'll cover the rest of today's Symmetrix announcements in a separate post.

Oh, and if you haven't stopped by The New EMC.com, you definitely should - it's a whole new experience. Today's announcement landing page is an excellent example of how the new technologies behind EMC.com provide a more rich and engaging approach to the company's web presence.

0.055: obligatory "ibm buys xiv" post

Well, I thought I'd wait a day and let the dust settle on this before I made any comments.

Turns out I saved myself a lot of redundant typing. Chuck Hollis covered much of what I would have said (albeit a bit more elegantly). I share his notion that IBM may be using a Web 2.0 smoke-screen to hide their real intent to use Nextra as either A): a response to DELL+EqualLogic and/or 3PAR; or B): as a replacement for the woefully under-funded (and near-dead) DS8000.

I also think there's a potential C): merge Nextra with SVC to solve SVC's emerging Rube-Goldberg scalability problems and get FlashCopy/Global Mirror compatibility onto a truly scalable platform. I guess that the lack of end-to-end data integrity protection is starting to tarnish the SVC image, with wholesale replacements and exorcisms being held on both sides of the pond (or so I've been told). But that's just me being me, I guess (and perhaps in a manner that's a bit more argumentative than Chuck would have written - I'm sure I'll be hearing from BarryW soon on that one).

Steve Duplessie and Mark Peters over at ESG did an good job of explaining what the Nextra is all about, and lends some credibility that this really might be all about Web 2.0 after all, given IBM's need to find a viable replacement for the now aging and somewhat archaic DR500 (tape is dead, haven't you guys heard yet?). But I don't think you really know what Nextra can really do until you actually hear what the current customers are doing with it, and it seems that all of them have lost their tongues for some odd reason. And for the record, I also think Steve's comments that this is probably at least as much about Moshe as it is about Nextra are right on.

At the very least, on his reputation alone Moshe will probably get IBM an audience with a few of those Wall Street IT shops that have banished Big Blue storage from their data centers because of all the incompatible product churn they've incurred since the days of RAMAC, Iceberg, Sharks and now the dead-end can-you-say-downtime DS8000's.

Not to be outdone, Fellow Blogger Tony Pearson took his own shot at explaining what he thinks is the revolutionary neat new technology in Nextra. Unfortunately, he doesn't have much understanding of the Centera architecture, so he mistakenly thinks is this all new. But heck, even though back before Christmas he was joining forces with TwoEgos in a premature wake for Centera, I'll give him a pass on the fact that Centera's been doing this exact type of blob striping and protection since day one (back at the beginning of 2002).

I'm feeling oddly benevolent to start this New Year for some reason...

0.036: data integrity and virtualized storage

Is your data really safe?

In what many think is a modern-day impression of Chicken Little, Robin Harris has been asking this question over on StorageMojo for quite a while. In his most recent blog post, he refuels his concerns using "evidence" presented in a Data Integrity research paper done by the folks at CERN.

I highly recommend you at least skim that document, as there are some interesting observations in it that could have far reaching ramifications in your own storage environment.

According to this paper, more than 3 of the MP3's or TiVo videos I have in my Terabyte Home are probably corrupted -and I might never know it!

Now Robin takes the 50,000 foot view of this, and comes to the conclusion that the world just may collapse soon if this data integrity issue isn't resolved. He even suggests that HEY! Shouldn't we be doing something NOW to avoid all this?

</sarcasm> (I leave it to the reader to figure where the opening tag belongs )

Good news, Robin: some of us have already been solving this problem. Been doing so for years, in fact...  
 

0.035: hitachi drops another shoe (it sounded like a slipper!)

I guess I should be ashamed. Embarrassed at least.

Yesterday, someone asked me why I hadn't yet commented here about Hitachi's baby USP-VM announcement made earlier this week, and I responded "what announcement?"

Yep. I missed it. Completely.

Not that I wasn't aware it was coming...Mr. T doesn't make the rounds on Wall Street on the arms of HDS PR folks for nothing, nor do you wake poor old Claus from his year-long blogging hiatus unless something really important is about to happen.

As I had prior blognosticated, there were (and still are) gaping holes in the initial USPV announcement - clearly the team back in Japan had much more in mind than had been announced back in May. And at least a few rumors indicated that many of these would make it through the QA gauntlet before the end of Q3'07.

Guess this stuff really is hard for everyone.

So I guess because I'd expected so much more, the actual announcement of the USPV "mini-me" slipped right under my radar. I probably shouldn't have taken Nigel's advice and stopped stalking HHSNBN (although it has been therapeutic not to read about yet another world calamity that UVM can solve for a couple of weeks, mind you).

But now that mini-me has been brought to my attention, you just know I have to comment. Interestingly though, this time I'm not alone in correcting the typical misleading marketing that the Hitachi Data Systems Santa Clara marketing miscreants have become known for.

It seems I have some new friends in my quest to keep things honest.
 

0.031: inside tiered storage - part 2 (options)

Part 2 of a planned 4-part series exploring the concepts and implementation of tiered storage. If you missed it, you should probably read part 1 (definitions) first.

Several weeks ago I was invited to sit-in on a "Peer Incite" conference call with the folks behind Wikibon.org. The topic had been advertised as a peer review of EMC's 7/07 announcements, but the topic leader (Peter Burris - or was it David Vellante?) chose instead to focus the discussion around the implications of EMC's announcement that the Symmetrix DMX-4 would be the first high-end storage array to offer native support for SATA-II disk drives, and specifically the 750GB devices. (You can read the collective results of that conference call here.)

One interesting aspect of this discussion was the clarity offered around the differing approaches for implementing tiered storage. I personally thought this one of the more valuable parts of the discussion, but it seemingly was not included in the posted summary. In fact, it was that omission that initiated the idea for this series in the first place (admittedly, I had initially thought I'd be able to cover the topic in a single post, but I couldn't manage to pull that off).

So in this chapter I'll explore the four different options for implementing tiered storage, as was discussed in that original call.

Of course, I'll add a little of my own color along the way.

And maybe even a surprise ending...

0.027: inside tiered storage - part 1 (definitions)

There has been a lot of talk of late related to tiered storage, mostly surrounding the applicability of using SATA devices in enterprise-class storage arrays. After posting a few comments and follow-ups on fellow blogger sites, I thought perhaps I might invest in making a more in-depth look at the whole topic from an enterprise IT perspective.

The way I see it, this whole notion of tiered storage is pretty broad, so I've outlined my approach to the topic into a couple of related posts that I plan to deliver over the coming days/weeks. Roughly, I think I'll tackle the discussion like this:

part 1: definitions

In the first installment (this one), we'll explore the definition of "tiered storage" - I say "we" because I'd like to collect your feedback on the subject.
 

part 2: options

Next I'll explore the various approaches to implementing tiered storage, using different companies and their products as examples.
 

part 3: challenges

Then I'll discuss some of the challenges of implementing tiered storage, both related to each individual option and across the entire spectrum (I'll give a little preview: there isn't yet a good solution that solves everything for everyone).
 

part 4: predictions

Finally, I'll take a look at what I think will likely be coming down the pike to help improve the overall situation.

Now, I probably won't get through all this back-to-back, so expect me to intermix this series with other topics over the coming days or weeks.

One important caveat - this series is about Tiered Storage, and NOT Information Lifecycle Management (ILM). As SNIA has defined, ILM is about the entire operational ecostructure (people, process, practice, tools & technology) employed to effectively align the business value of information with the IT infrastructure throughout its' lifecycle. This series of posts will explore perhaps the most important of the infrastructure tools - tiered storage - that can be employed in support of ILM, and the various means this tool can be deployed.

So let's get started...

0.024: green envy and twisted truths

You usually can tell that you're on to something big when the competition starts trying to reshape the facts.

Today's case in point: EMC's recent DMX-4 launch and specifically the focus on the DMX-4's power efficiency advantage.

In the launch, EMC made three claims about the DMX's so-called "green" advantage over the competition:

1. The current DMX-3 requires less power than the competitor's high-end storage products
    
2. The DMX-4 and Enginuity 5772 delivers even more performance without requiring more power than the DMX-3
    
3. The DMX-4 will support the new 750GB SATA-II drives, for an even greater power savings (lower $/GB and Watts/GB/year)

Pretty simple and straightforward.

But obviously also a very uncomfortable set of claims for both the competition. And apparently for the EMC nay-sayers who apparently can't accept the notion that EMC could actually be better on anything, much less such a fundamental matter as power & cooling.

He Hu Shall Not Be Named (Nor Linked) attempts his usual blogketing misdirection by focusing on the math he couldn't decipher (because it's not that mythical Hitachi Math, I guess). Of course he also asserts that virtualization is the answer to everything, now including Green IT (is World Hunger next?). On the other coast, IBM Brand Manager (and Fellow Blogger) Tony Pearson tries to redirect the conversation to focus on the power-efficiency of Linux mainframes vs. Intel servers, even as IBM remains the major reseller of EMC's VMware virtualization platform for Intel servers. Neither disavows EMC's claims, or even mentions the power utilization of their respective high-end storage products (much less defends their power-hungry designs).

Then there's the self-anointed Anti-EMC community, made up of certain other Fellow Bloggers, Industry Analysts, 2-ego-centric industry pundits (he hates to be included in the 'Industry Analyst' category), and the occasional blog comment/message board/discussion forum "contributor." These folks have chimed in from virtually every corner of the world to challenge the claims of DMX-3 and DMX-4 power advantage. And almost to the person, they mistakenly assert that the DMX-4's power advantage is only dues to the SATA drives, making it a hollow claim. From that simple misrepresentation of the truth, the discussion devolves into challenges about the performance, applicability or viability of low-cost storage in an enterprise array.

Allow me to set the record straight -

Both the DMX-4 and the DMX-3 require less power (& cooling) to support the identical drive, port and memory configurations as the competition.

0.019: dmx-4 and oh so much more

As you probably already have seen, EMC had a pretty major platforms update announcement on Monday, with updates to virtually every storage platform product we offer.

Given the size of the company and the scope of our product portfolio, gone are the days when we have the luxury of launching only on a single product at a time -- there just aren't enough weeks in the year (and it does take weeks, with all the pre-briefings, scheduling, invitations, etc.). So we pretty much have to do these so-called "roll-up" announcements, and this one was pretty significant.

In fact, there were so many, many things announced across Symmetrix, CLARiiON, Celerra and Centera that it's near impossible to summarize them all in one place. For the next several weeks, if you want to learn about specific updates, I invite you to visit www.EMC.com directly. You can select the key product line areas from the rotating landing page banner, or you can follow the link to the Executive Summary presented by Barbara Robidoux, the Storage Platforms Marketing VP (but be forewarned, she has a LOT to summarize!).

I'll throw in a special recognition of EMC's marketing folks who created this launch - they've done a bang-up job of announcing a boatload of stuff without the overwhelming use of superlatives and hyperbole. In fact, it's obvious that there was a focused effort to communicate this announcement in terms of realizable customer benefits, instead of mind-numbing speeds-and-feeds. It certainly makes everybody's job easier when we don't have to answer questions like "so what?"

But if you really want to know the inside scoop about the launch, you've come to the right place. Well, so far as the Symmetrix side of the launch is concerned that is. My pal Storagezilla has adeptly covered the CLARiiON, Celerra, Centera, and RainFinity announcements over at his blog.

So, want to know more about DMX-4? Read on, Gunga Din!

0.013: customers say the darnedest things

Well, it's the last week of the quarter, and things around work are much like they probably are at virtually every product company on the planet - everybody is on-call to do whatever it takes to close business and get the products shipped in order to recognize the revenue this quarter. Even many of us in engineering will be called in to help close deals - we even have a slogan for this practice: "Everyone Makes Closing Calls" (that's the EMC "squared" version).

Down the road in Franklin and Apex and over the pond in Cork, at this time of the quarter EMC stands for "Empty Manufacturing's Closets," the goal being that everything is in the trucks (or lorries) and well down the road by midnight Saturday, with the manufacturing floors as barren as Old Mother Hubbard's cupboards.

Given this quarterly ritual, and next week's impending US Independence holiday, I expect the blog traffic to be relatively lighter this week than others. So I thought I'd have a little fun between briefings and con-calls and explore a few of the odder things I've heard from customers and prospects over the years.

Regarding the title of today's entry, many of you probably remember the similarly-titled children's show hosted by Bill Cosby back in the 90's. Many of you will also remember that it was Art Linkletter who first ran the concept as a segment on his CBS radio show back in the 1940's and later on his TV show (from 1952 through 1970). Fewer of you will actually remember the name of that show: it was "Art Linkletter's House Party."

There - the genealogy is documented. Now I don't want to see any folderol out in blog-land about who actually invented the darnedest things nor who stole them from Art. Especially not from a certain inebriated mis-information peddler. OK?

0.008: world's largest appliance

Amidst all the hubbub and blogging about Hitachi's new USP-V, several people (including yours truly) noted that it seemed odd that Hitachi would double the processor speed inside their array, yet didn't add support for more drives or larger drives than the original (30 month old) USP supports.

And when I noted that only the DMX-3 supports more than 1152 drives (up to 2400, in fact), I was promptly slapped with the "FUD-slinger" label. I was even challenged to defend myself with evidence of ANY customer using 2400 drives, and my assertion that there are several installed DMX-3s with more than 1152 drives (the current USP/USPV maximum) was seemingly dismissed as insufficient evidence of demand.

On Monday, at EMC World 2007 in Orlando, EMC Introduced The World's Largest Open Systems Virtual Tape Library, built upon configurations of the Symmetrix DMX-3 with up to 2400 500GB low-cost Fibre Channel drives. (This is apparently what the Backup Wizard was hinting about so cryptically last week).

Although we may not have sold or installed one yet (the DL6000's won't be GA until June), I feel somewhat vindicated. The exploding customer demand for cost-effective VTL (and backup to disk) solutions are precisely the sort of applications that motivates EMC to build, qualify and support modular arrays that can scale to huge proportions within a single platform.

And now we've taken the World's Largest Storage Array, and made it also the World's Largest Virtual Tape Appliance.

Go Figure!

0.005: self tuning storage - today & tomorrow

Over in the land of Dullness, Chris Evans drops an interesting challenge - self-tuning storage.

For now, I'll overlook his jabs about the "whose array is better" tete-a-tete and focus instead on the admittedly more interesting story (although I will note that Hu's pretty much been playing solitaire in the "mine's better" game until the Anarchist came along ;*).

Self-Tuning Storage: that's what we've been working on with Symmetrix for about 16 years.

Now, I was going to write about this from an entirely different angle, exploring how no matter how much you improve on the interface for managing performance, customers will want more. I'll (eventually) get to that, but first things first.

Fact is, Symmetrix was the first self-tuning storage array, and remains essentially the only array that actively optimizes itself, in real time, dynamically under changing workloads, with little or no need for human intervention.

It's not yet perfected or complete. But Enginuity 5772 takes this to a new level.

0.004: get ready for tagma-too!

Word's out - there's soon to be a new USP from our pals at Hitachi/HP/Sun. And I'm sure you didn't hear about it first from me.

It's about time.

Hitachi had been on a pretty set schedule of bringing new high-end platforms to market just about exactly every 24 months. And in fact, it seems many customers were specifically told in early 2006 to expect the next-gen "Tagma" in the September 2006 (ish) time frame, almost exactly 2 years after the original USP12000/9990v was announced.

That would make next week's (rumored expected) announcement just about 8 months late. Makes one wonder what when wrong - what happened in 2006 to cause such a delay? A delay so long that Hitachi's Wall Street Minions were out in force late last summer, admitting to anyone who'd listen that the company would likely suffer significant loss of market share through calendar Q4'06 and Q1'07.

Although the numbers aren't all in yet for Q1'07, the predicted loss of storage market share the last couple of quarters looks very likely to have been correct. In fact, estimates I've seen indicate that IBM's DS8000 surpassed Hitachi's USP+NSC sales in the high-end for the first time back in Q4'06.

After such a long wait, I'm pretty sure what the folks over at Hitachi are thinking right about now...

...Welcome to the machine!
