5.005: who said it couldn't be done?

They said "it" couldn't be done. They said nobody else's array could do "it" – that only their array architecture could handle "it." They said all kinds of things about how "it" was going to bring the demise of Symmetrix, because Symmetrix would never do "it." Even if we could do “it,” they said we wouldn’t – but they said we can’t. 

But they were wrong. VERY wrong.

Today EMC announced "it" is now available on VMAX. And then EMC went one better than they ever imagined – EMC took "it" further than they have been able to, even after all the (8+) years they have been shipping "it."

And of course, they will try to undermine the fact that they now have DIRECT competition from another array vendor who has implemented "it" - highlighting the history of EMC bashing "it", as if that matters any more. As I have noted before, being "first" is only important until there is a second - then all that matters is which implementation is better. And so they will childishly act like first means best perpetually.

Have you guess what "it" is yet?

More importantly, do you know who “they” are?

Read on to see what they never expected…and should have feared...

4.008: truth or d@re

Back in December 2010, EMC’s Enterprise Storage Division (ESD) released a major new software update for VMAX, embodied as Enginuity 5875. Among the more than 50 new features was  the Data at Rest Encryption feature (which we internally abbreviate as “D@RE”). And then back in May, we updated D@RE with support for RSA’s external key manager as a complement to the embedded RSA key manager in the original release.

Admittedly, Data at Rest Encryption is a feature that is offered by very few storage platforms – it is almost exclusively found only on enterprise-class arrays, in fact. And of all the implementations, Symmetrix VMAX’s D@RE implementation is highly differentiated – a breed apart from would-be competitors (as is FAST VP, VMAX’s automated storage tiering implementation, but that’s not today’s story).

Separating VMAX D@RE from everyone else  are features such as:

• Support for any and all drive types supported by VMAX. Where some other implementations are limited to offering encryption only on special drives with built-in encryption, VMAX D@RE encrypts all the data on all the Flash EFD drives, enterprise 10K and 15K HDDs, and 7200rpm “slow-spin” HDDs;
• A unique key for each and every drive in the system. With up to 2400 unique keys in a full-blown VMAX, the life of a crypto-criminal is much more difficult, especially as compared to competitive offerings that support a max of 31 keys for the entire array (the more data protected by a single key, the easier it is to find the key);
• Complete and transparent data at rest encryption for any and all hosts, applications and storage services, including Virtual Provisioning, FAST VP, SRDF, TimeFinder, VAAI, etc.
• Automated assignment of unique keys to every replacement drive and rekeying of data as the drives are rebuilt;
• Virtually undetectable performance overhead for either encryption or decryption (see chart at right);
• The ability to remove the keys from the array altogether when physically relocating the array as added protection against the accidental or malicious loss of the array (or drives) during the move. Deliver the array and the keys to the new locale separately, and restart the array without delay after the two are reunited.

To my knowledge, no other enterprise storage array offers all of these native capabilities of VMAX D@RE.

Arguable, I could stop there. But wait…

It gets BETTER!

4.005: you call that big storage?

Earlier this month, Hu Yoshida posted yet another missive in his never-ending series of hype about the virtues of array-based virtualization. In it, he cited records from Hitachi's tracking systems showing the top VSPs and USP-Vs ranked by total capacity. Oddly, the older USP-V racked up the largest capacity deployed on a Hitachi array, even though its maximum internal capacity is less than the newer VSP (a feat that Hu asserts is because the USP-V has been in the market longer (4 years vs. the VSP's 10 months).

I had to laugh, especially given Hitachi's long-standing (and ridiculous) claims of supporting more than 240-something PB of external capacity.

For the record, being launched in April 2009, VMAX has indeed been shipping longer than VSP, but not as long as the USP-V. VMAX also does not (at the time of this writing) support virtualization of external storage.

With those caveats, herewith the top 10 VMAX arrays, sorted by usable internal capacity:

That's right, folks. The smallest of the top-10 VMAX arrays is larger than all reported VSPs and all but 2 of the largest USP-Vs.

Note also that several of these VMAX arrays are over-provisioned. Leveraging Symmetrix Virtual Provisioning, these arrays are exporting more capacity than they physically support contain. This affords customers improved capacity utilization, driving up efficiencies and driving down acquisition and operational expenses. In addition, most of these arrays are already positioned to leverage the benefits of Symmetrix FAST VP (if they aren't already – you can't tell from this report).

I have to say, though, that I almost spewed coffee on my keyboard when I read Hu's claim that the largest USP-V was actually virtualizing TWENTY FOUR frames from different vendors.

In an age when floor space, power, cooling, maintenance charges and operational complexity are seen as negatives to the bottom line, I'm actually quite surprised that there is even one USP-V customer operating in such an extremely inefficient manner.

It is quite probable that this poor customer would realize significant savings were he/she to replace that multi-headed behemoth of intertwined FC switches and multi-vendor arrays with the elegant simplicity of a single VMAX.

At the very least, he or she wouldn't be such a lonely pioneer of mega-capacity consolidation.

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!

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.

 

3.020: reality check - vsp vaai support

I've seen lots of bluster lately from the Hitachi PR machine about VSP being the first virtualization platform to support VMware's vStorage API for Array Integration (VAAI).

When you're next to last delivering something, I guess you gotta try something (I note that IBM has yet to deliver VAAI on either DS8K or on XIV – not surprising, since both seem to be on life support, if for different reasons).

Hitachi have spared no blather in their messaging. If you were to believe their PR proclamations, you would expect to gain all the benefits of VAAI without waiting for your existing storage platform to be upgraded with VAAI support. Just tuck it behind a spanking new VSP and forget all your troubles, they seem to say.

Reality Check time.

As Stephen Foskett essentially explains in his post VMware VAAI Storage Array Support in Plain English, VAAI was developed by VMware in cooperation of industry storage suppliers to address TWO issues:

1. Copy and Erase operations place a huge load on the servers, network and storage arrays
2. The SCSI reservation locking mechanism does not scale efficiently for large LUNs nor for large number of hosts sharing the same LUN(s)

What the Hitachi PR machine fails to mention is that moving the Bulk Zero and Bulk Copy workloads off of the server CPU is not the only benefit of a good VAAI implementation. In fact, with Done Right implementations like VMAX, moving these operations into the array allows the array to optimize the operations to further reduce the overhead and impact.
 

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…

3.011: hot air reclamation

As I said in a prior post, sometimes we in the storage industry misbehave.

And other times, we spew fish stories – the kind that would make Pinocchio’s nose grow a couple of feet instantly.

The latest fish tale to be exaggerated beyond all sense of reality is the Unused Space Reclamation geyser, and to hear it told is to be convinced that the world of underutilized storage hath been all but eliminated at long last by the ingenuity and design of a unique new magic trick that allows host software to tell storage systems they are no longer in need of certain blocks within a LUN.

Now, don’t get me wrong – this feature is extremely valuable and it will undoubtedly help us all to improve storage utilization and efficiency. But I’ve seen practically every vendor who is shipping support for this feature today practically claiming to have invented it, that it’s a key differentiating feature for their platforms, and that THEY are the ones driving the hypervisor, host operating system, file system, database and volume manager vendors to implement this new feature.

Reality Check Time

Folks, the fact is that the T10 SBC-3 committee has stabilized the RFCs for the two (yes 2) new SCSI commands that underpin all this hoopla. With stable RFCs, vendors are now able to implement one or both of these new operations without concern that the API is going to change (again). And these standards have been under development for over a year, with representation and comment from practically every vendor in the list I scribed above – as with most standards, it has been a communal effort.

Somehow, the early adopters see no need to explain these facts to their audiences, allowing encouraging them instead to think that each vendor alone has mastered alchemy to turn deleted files into reusable space.

Alchemy, indeed…

3.005: transparency as a competitive advantage

Several years ago, Symmetrix customers let us Symmetrix developers know that they wanted more transparency from us about code bugs issues. They wanted to know if anyone else had seen problems like they were seeing, and (more importantly) what the solution was. They wanted to know the extent of our testing, and (more importantly) they wanted to know whether their environments fit inside the standard test/regression scope that a release went through before GA. They wanted a way to identify things in their environments that weren't in step with the EMC Support Matrix. They wanted to know the bugs issues we fixed in each release, even if it had nothing to do with their environment. And they wanted us to protect them from issues that we knew about, even if THEY weren't aware of the issue.

And they made it quite clear they weren't going to take "no, sorry" for an answer.

And so began the virtuous cycle of transparency. For most of the last decade we have had teams focus on providing the tools and information that customers were demanding. Driven by customer feedback, we have expanded this transparency far beyond the original "baby-steps" into what today is at least a differentiator, if not a huge competitive advantage.

Just some of the things we've done:

• We changed the EMC eLab Support Matrix from a printout of hundreds of pages into an on-line database that supports ad-hoc and template inquiries;
• We provided customers the means to create templates of their environments that could automatically be used to validate against the on-line support matrix;
• We tied our test matrix into these systems so customers could see the scope of configuration testing that was applied to each release prior to GA;
• We provided customers with on-line access to all customer-reported issues, and empowered them to track progress, work-arounds and solutions to the problems as they were identified and implemented;
• We provided them with an automated interface into the issues database that can block scripts and management interfaces (GUI, SMI-S, etc.) from performing operations that are known to invoke potential issues – in real time, as they are discovered;
• And we document every potential DU/DL issue we fix in New Releases, Service Releases and Maintenance Releases – even if the issue has never been seen by a customer.

This last one is perhaps to most transparent thing we've ever done; more importantly, customers tell us that they really like what we've done. And all of this transparency is a foundational component of our overall commitment to TCE – maximizing the Total Customer Experience of our installed base.

2.044: ibm dumbs down storage marketing (again)

OK, this isn't going to be another one of my competitor-bashing diatribes. I've learned my lesson, based on reader feedback on my comments about IBM's past transgressions (who can forget IBM's initial "Let them use Tape" response to flash drives?)

Nope, this time, I don't have to be the one to do the tear-down: independent storage consultant self-proclaimed IBM proponent "PRJ" has exposed the (dare I say it) stoopidity in his post IBM Storage UK Has Codified Stupidity. In the middle of his post he highlights the following.

Yet again, this does not mean XIV does not meet some needs. What it does mean is that XIV is still not equal to nor does it offer performance comparable to the DS8000, and that IBM has said you - the customer - are too stupid to understand this blatantly obvious fact.

If I wrote that, you'd have blasted it as blatant FUD. But this guy says that he LIKES IBM…go figure.

And it appears that IBM Storage US is no better.

Case in point: in his latest post covering this week's IBM Storage product announcements, arch-nemesis Tony Pearson couldn't resist taking an entirely unrelated swipe at me and V-Max at the end of his post. (Tony clearly didn't appreciate my publicizing the impending death of the DS68000, nor my chastising of the way he (apparently intentionally) twisted a recent Chuck Hollis post into the offensive and insensitive accusation that EMC markets storage to terrorists).

In his attempt to take the high ground, TonyP steps into the land of Codifying Stupid when he includes a link to an (IBM-funded) "ITG white paper" titled Cost/Benefit Case for IBM XIV Storage System - Comparing Costs for IBM XIV and EMC V-Max Systems, and he then uses that paper to support an assertion that the XIV is up to 63% less expensive than "a comparable" V-Max.

With an assertion like that, you know I had to respond.

 

2.035: fast, nice and easy

With the introduction of FAST, Storage Tiering can now be automated to optimize performance and reduce both CAPEX (acquisition costs) and OPEX (people, operational and maintenance costs).

In support of the introduction of FAST for the Symmetrix V-Max platform, EMC has made several key enhancements to Symmetrix Management Console (SMC) and Symmetrix Performance Analyzer (SPA). The goal behind these changes is to radically simplify storage allocation and management in a FAST environment, largely by building upon the constructs of Auto-Provisioning and non-disruptive V-LUN migration that were introduced on the initial software release for V-Max back in April 2009.

That's right, boys and girls. Despite all the misinformed FUD you've been hearing from wanna-bee competitors, Symmetrix V-Max is indeed both FAST and easy!
 

2.033: v-max is much more than fast

Hot on the heels of last week's FAST introduction comes today's formal announcement of additional features and hardware for Symmetrix V-Max. Collectively, these enhancements are designed to improve the efficiency, flexibility and cost-effectiveness of V-Max in its rapidly expanding community of customers.

Even as some competitor bloggers struggle to comprehend the architecture of V-Max and/or the differentiated value of Fully Automated Storage Tiering (as opposed to Professional services-Based Management), today I will offer some insights into the other updates for V-Max that started shipping to customers at the end of November '09.

If you're a V-Max customer or prospect, there's a lot more than just FAST in this year's Symmetrix Christmas/Holiday package:

• New Hardware support
• Virtual Provisioning enhancements
• Performance enhancements
• Replication Enhancements
• Security enhancements

Let's take a peek at each of these areas, shall we?
 

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.

 

2.023: 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…
 

2.010: 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?)!
 

2.003: sgt. friday and the ibm flash competency debate

It appears that both Tony Pearson and Barry Whyte are wont to try to diffuse the debate I started in my ibm really really doesn't get flash post with yet more innuendo, misinformation and unsubstantiated fear, uncertainty and doubt (FUD).

Which is all they can do, I guess, unless they are going to publicly explain in concrete terms why IBM is unable (or unwilling) to support the larger-capacity STEC ZeusIOPS drives in the DS8K that EMC has been shipping for Symmetrix since February 2009.

In the interest of those who really don't want to sift through the cruft to get to the reality behind the discussion, I outline for you here the simple facts of the debate:

1. EMC is shipping today the two largest-capacity enterprise-class flash drives available in the market – the STEC ZeusIOPS 4Gb/s Fibre Channel SLC-based drives in 200GB and 400GB capacities.
2. EMC refers to these drives as "Enterprise Flash Drives" (EFD) in recognition of their specific designs to support the availability and data integrity requirements of enterprise storage, and as opposed to the more common drives targeted at the server or laptop markets.
3. IBM reports to be shipping today the STEC ZeusIOPS 4Gb/s Fibre Channel SLC-based drives in 73GB and 146GB capacities only.
4. IBM calls its flash drives simply Solid State Drives (SSDs).
5. EMC's 200GB EFD and IBM's 146GB SSD are the same physical STEC ZeusIOPS drive, with 256GB of internal SLC NAND flash – the only difference between the two is that the EMC version provides more usable capacity from the same amount of flash.
6. EMC alone ships STEC's newest and largest ZeusIOPS 4GB/s FC drive with 512GB of SLC NAND, formatted for 400GB usable capacity.
7. EMC's 400GB EFD further reduces customer cost per usable GB, enabling customers to get more than twice the usable capacity from the same number of drives as IBM's largest SSD, or to use fewer 400GB EFDs to meet their capacity targets and thereby enjoy not only lower acquisition costs vs. the IBM DS8K, but reduced power, cooling and space requirements as well.
8. EMC asserts that the 200GB and 400GB formatting does not significantly reduce the practical life of either drive in any workload when used in EMC arrays, including pathological/artificial write-intensive workloads.
9. EMC stands behind this assertion with the same replacement and service warranty as is offered for both Fibre Channel and SATA-based hard disk drives in EMC storage arrays.
10. IBM has not yet explained publicly why it can not (or will not) offer similar capacities and the corollary cost savings on the DS8K.

Just the facts , ma'am.

This post is from the storage anarchist.

1.061: the voice of the customer

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.

1.060: the rest of the v-max launch

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

But wait – there's more!

OK, not really more than has already been announced, but there were several parts of yesterday's announcements that I didn't personally cover here on my own blog.

So I thought I should highlight a few of them so that readers and visitors get a complete picture (for a complete link page of relevant launch articles, visit my first Overtake the future post):

• Auto-Provisioning – a key new feature that streamlines and accelerates the process of storage allocation to clustered servers, as in VMware ESX clusters. Both Steve Todd (Information Playground) and Mark Twomey (Storagezilla) provide in-depth coverage (Mark even links the demo video).
• Symmetrix Management Console (SMC) Templates & Wizards – new features that automate a wide variety of common storage management functions to make them more easily repeatable and delegable. Steve included insights into these in the post linked above as well.
• VMware integration – beyond Auto Provisioning and the continued Symmetrix integration with VMware's Site Recovery Manager, there is also new EMC Storage Viewer plugin for VMware's vCenter. This plugin visually bridges the gap between VMware admins and storage admins. Chad-the-Virtual-Geek-Sakac answers perhaps the most frequently-asked question in the press yesterday: "So, just how *IS* V-Max integrated with VMware?"
• New SRDF/EDP (Extended Distance Protection) – essentially, zero-data-loss multi-hop Asynchronous long-distance replication, without the need for a full copy of the data volumes in the middle site – reducing the cost of extended distance business continuity. 'Zillaman does the honors on this new SRDF option as well…
• V-Max Quality – a common concern about any new product is how complete and stable the product is at initial release. Given the significance of switching to Intel processors and changing the underlying architecture required to deliver Symmetrix V-Max (not to mention the incredible scale of the new system), the focus on delivering Quality on Day One has never been higher. Although not a V-Max developer himself, Steve Todd went behind the scenes to explore some of the innovative strategies for quality taken by the V-Max development organization.

All in all, there is a TON of information here – I know I personally wrote over 10,000 words about the new products and architecture in support of the launch.

And note - I wrote these posts over the course of about 10 days, so don't feel bad if you can't read it all in one sitting.

1.059: fully automated storage tiering (fast)

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

Today's announcement is chock-full with exciting news.

First, there is the breakthrough Virtual Matrix Architecture, combining the best of Scale Up and Scale Out to revolutionize enterprise storage.

And then, the Symmetrix V-Max itself, integrating the proven power and functionality of the Enginuity storage OS on a new industry standard platform to deliver cost-effective flexibility and a new definition for ease-of-use in enterprise storage.

Next up? Perhaps the most exciting (and unexpected) announcement of all.:

Fully Automated Storage Tiering (FAST)

As Chief Strategy Officer for the Symmetrix Product Group, my role in today's global Virtual Launch is to describe and answer questions about FAST in one of the half-dozen or so "break out" sessions available to all participants. Given the high level of interest in the topic, I thought I'd take a few moments and discuss FAST here as well.

So, what exactly is FAST?
 

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.

1.052: over-hyping wide striping

When the capabilities you use to differentiate your product in the market are no longer unique, marketing tends to morph into hype.

That appears to be what’s happening to 3PAR.

Once the paragon of Thin Provisioning and Tiny Chunklets, today they struggle for relevance in a market where virtually every storage platform offers thin provisioning as just one among a long list of features.

What’s worse is that 3PAR, like XIV, is saddled with an architecture that makes it difficult (although surely not impossible) to integrate support for Enterprise Flash Drives. In fact, along with NTAP and XIV, 3PAR remains one of the few companies that have not yet figured out how to deliver the performance benefits of flash storage technology to their customers.

Marc Farley, who I respect immensely (and not just for his rappin’), stepped out this week in his blog to assert that while 3PAR is working on flash, they are “in no rush to be a me too player.”

(Out of respect, I’ll pass over that obvious softball.)

But I did find his suggestion that Wide Striping was 3PAR’s answer to EFDs rather funny. Almost as hilarious as IBM’s assertion that had me rotflmao! last year – the one where they said that their customers didn’t need flash drives, they needed TAPE!

Even more, um, dare I say ridiculous, was Marc’s assertion that EMC was using EFDs to avoid the efforts of re-architecting their products to deliver wide striping.

No offense intended, Marc, but you know I’m not one to let anyone get away with such misleading hype and outright false FUD.

Allow me to set the record straight…

1.034: i've been working on the (redacted)

As the end of the year draws near, I realize I've not offered any explanation for my recent rather lengthy spells of silence here on my blog.

The thing is, I've been busy, working on several rather exciting projects that quite honestly have been consuming nearly all my waking hours. Some really neat, game-changing stuff – even more interesting perhaps than the stuff I was working on last year at this time!

Not only have these projects kept me away from the keyboard, but I've been living in abject fear that I'd somehow slip up here on my blog and reveal some corporate secret or another in what surely would have been a very poorly timed CLM.

But you know me – anarchy means there are no rules. So I sucked it up and went ahead and wrote a post anyway.

But with my last sliver of common sense, I paused just before hitting the "Publish" button, and sent my draft out for a peer review.

Follows is what came back from my wizened peers and advisors…(and thanks to all of you for saving my butt!)

 

1.031: meet the symmerator

Ever wonder what happens to old Symmetrix arrays?

Frequently customers will "cascade" them as they age: as new Symms are purchased for production deployment, the older arrays that they replace often become the BC/DR "target" at the other end of the SRDF link.

And the old SRDF target? Well, some simply get returned at the end of the lease term, while others get traded in for credit towards a shiny new Symmetrix.

Some old Symms, of course, meet with a somewhat less fortunate demise:

How sad....

But at least one old Symmetrix 8000-series array has found happiness in a totally new retirement career...
 

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.
 

1.008: 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...

 

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...
 

0.069: i work with smart people

Lots of them, actually.

In fact, pretty much everyone I work with is smart. By definition. That's why they are at EMC in the first place - the company seeks out smart people, and smart people like to work with other smart people.

As a result, there are an amazing number of smart people at EMC.

But you know, with so many smart people around you, it is all too easy to overlook just how smart they really are.

Now, before I go any further, it is important to note EMC is intensely focused on inspiring, nurturing and acknowledging the contributions of its people. In fact, the most recent edition of EMC.Now (a quarterly magazine for EMC employees worldwide) included a review of several of the newer ways that EMC is cultivating inspiration across the company. I thought the article might be of interest my readers, so I requested and received permission to reprint it here:

EMC.now: Inspiration cultivation
Copyright 2008, EMC Corp. Reprinted With Permission.

After reading that article, you'll understand that inside EMC we frequently get the opportunity to celebrate the innovative contributions that our fellow employees around the globe make to the continuing success of EMC - it's part of our culture.

But when one of your peers gets external recognition, and it's the kind that puts him in the  company of the most notable software engineers in the history of computing, it really makes you sit up and take notice. I mean, to be recognized alongside the inventors of UNIX, TCP/IP, the remote procedure call, the World-Wide Web, Mosaic, java, TeX & PostScript, SMALLTALK and VisiCalc (to name a few), well...that puts you in a whole different class of "smart" in my book.

So please indulge me this post to say "Congratulations" to Amnon Naamad for his recent ACM Software Systems Award...

 

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! 
 

0.042: yeah, what he said

Chuck Hollis' blog today is a tribute to EMC's (not so) "secret" sales force.

I too am down here in the Land That Walt Built, surrounded by those who are inarguably EMC's best and brightest, and I just wanted to add my shout out to these unsung heroes.

And importantly, I don't mean "unsung heroes of EMC."

No, as several of the customers who have appeared on stage today have testified, this community of technology specialists are the Trusted Advisors who are helping some of the world's most demanding IT organizations wade through the ever-changing technology landscape to solve information challenges not even imagined by the one-trick-pony startups that seem to attract so much attention. And without these insightful ladies and gentlemen, there are an awful lot of household-name information enterprises that wouldn't be who they are, and there is an awful lot of digital information that you and I just wouldn't be taking for granted every day.

So my "thank you" to this community goes out for the challenges you handle every day, AND for the challenges you bring back to me and my peers back in headquarters. As many of us discussed today, understanding and responding to the challenges our customers face is an EMC competitive advantage that doesn't happen on trade show floors or in catered cocktail seminars. No, it happens only because you have earned the right to live, breathe and influence our customers' IT strategy and infrastructure.

My personal and professional thanks to each and every one of you. You are indeed our EMC's most important competitive advantage.

0.033: elvis has left the building

Yesterday afternoon it became official: with the signing of the Product Ship Authorization (PSA), Enginuity release 5772+ ("plus") and the Symmetrix DMX-4 are now Generally Available.

Less than 24 hours later, shipments of both are already underway (along with the updated releases of Symmetrix Management Console, Solutions Enabler, the SMI-S provider and the mainframe Host Components, just for completeness).

Last month, I described the content and feature set of DMX-4 and the accompanying Enginuity 5772+ release (which also runs on existing DMX-3 platforms). There are lots of highlights, including the DMX-4's 4Gb back-end and its first (and still only) native support for SATA-II drives. And numerous software enhancements that deliver significantly improved response time, throughput and replication capabilities for both DMX-3 and DMX-4.

Since the announcement, customer interest in DMX-4 and the new software update has been strong, while the competitive response has been noticeably weak . In fact, I think that almost all of the DMX-4's in backlog will be shipping with at least some 500GB SATA-II drives alongside the faster FC capacity, in stark contradiction to the assertions that customers (and certain vendors) don't want to put lower tier data into their Tier 1 platform.

And like I said - it's great when you're the only SATA game in town. And even better when it's a game customers want to play. I expect our sales teams will be leveraging this /GB advantage pretty heavily for the foreseeable future.

Hats off to the team of development, quality assurance, customer service, product management, marketing, professional services, training, manufacturing, finance and human resources for a job well done! It takes more than a village, and y'all done good.
 

but wait - there's more!

0.029: a perspective on software architecture and engineering

I've been participating in some brainstorming/debates about the requirements and planning the implementation process for one of those "next big thing" type projects over the past several weeks (no, sorry, I can't tell you what it is ).

One of the clean-sheet discussions we've been having is about which comes first: hardware or software? Now, deep down, we all really know that the answer is that we have to design a system of complimentary parts. But it is somewhat funny (to me, at least) that the Software Gurus want to focus on the hardware first, while the Hardware Gurus want to know what the software intends to do before they tack down a strawman for the physical platform.

At least everyone is actively working together, which is always a plus.

From the HW perspectives, designing the hardware platform is reasonably straightforward - in fact, we already have our equivalent of the back-of-the-napkin design spec completed (in full-motion PowerPoint, no less). And from the SW perspective, well - you just gotta admire the cowboys who are confident that they can "break" (or "gentle") just about anything the HW dudes throw at them.

But we haven't quite converged on how the whole thing's supposed to work when we're done.

So when one of us challenged the team to start roughing out the Software Architecture, we all got a chuckle by the following emailed response from one of the lead SW engineers...

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!

0.008: 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.

0.003: beware the blogger: urban folklore at work

The trouble with tribbles (er) blogging is that you just never know who (or what) to believe. Too bad there isn't an automated BS Detector that could tell you in advance when something simply isn't true.

Usually, these misrepresentations result in little measurable or lasting damage. But occasionally they take on a life of their own. Left unchecked, they get repeated so often and with such conviction that people actually start to believe them.

In many (hopefully most) cases, such untruths may be unintentional and accidental. These usually get caught early, and before they are unwittingly repeated far and wide. I'm sure that sooner or later we all get caught in a misunderstanding or even the context-changing typo here and there.

But all too often, these untruths have every appearance of being intentional. There are those who stop at nothing to make a point, and who have no qualms in adjusting the facts to support their position. And others will resort to the age-old marketing tactic of comparing their TODAY product to the competition's YESTERDAY product in their quest to establish the perception of radical superiority.

And some people are so durn good at twisting truths that their assertions become part of the urban folklore sometimes faster than facts and realities do.

Who ya gonna call?
