June 20, 2009 – If you’ve moved beyond test/dev and into full production with your virtual server deployment, you’re well aware of the fact that as ‘VM sprawl’ creeps in performance goes down. And you’ve also probably figured out that in the majority of cases, SANs are the culprit.
In fact, in a presentation at the VMworld Europe show in Cannes earlier this year (no, I didn’t go), Scott Drummonds, VMware’s group manager, technical marketing, said that 90% of the performance problems in VMware environments were SAN-related.
In researching an InfoStor Special Report on SAN management in virtual server environments, I checked with some industry analysts and end users and that percentage may be closer to 70%, but nevertheless it’s clear that in order to maximize performance of virtual server farms you have to maximize storage performance.
But first, you have to monitor and analyze performance across your entire virtual infrastructure, particularly the SAN fabric. In researching the Special Report I came across some tools that you should look into before you actually try to tune your environment, because “you can’t optimize what you can’t measure” as the folks at Virtual Instruments say.
Those tools include Akorri’s BalancePoint, NetApp’s SANscreen VM Insight, and Virtual Instruments’ VirtualWisdom (which is based on the company’s NetWisdom and is currently in beta, with general availability slated for the fourth quarter).
The Taneja Group research and consulting firm refers to these products, and others, under the umbrella term ‘virtual infrastructure optimization, or VIO.’ These cross-domain monitoring and analysis tools provide very deep visibility into the virtual infrastructure, with an emphasis on performance analysis and optimization recommendations.
I spoke to SAN administrators that were using some of these tools and I’d highly recommend at least taking them for a test drive if you’re having any performance problems in your virtual server implementation.
Also check out a recent Webcast, archived at infostor.com, titled Eliminating the I/O bottleneck that limits scalability in today’s virtual servers. The main presenter was Greg Scherer, Neterion’s CTO, and although it does have some Neterion-specific content it’s an excellent look at I/O issues that often crop up in virtual server environments.
That Webcast was the first in a four-part series on Virtual Servers and the Impact on Storage, brought to you by InfoStor and our partner, Virtual Strategy Magazine.
The next Webcast in this series is coming up fast: On Thursday, June 25, 10:00a.m. PDT, 1:00p.m. EDT, we’ll host Virtual Servers: Six Ways to Reduce Your Backup Window. The key presenters for this Webcast will be executives from Vizioncore. To register, click here.

Tucci woos Data Domain employees
June 9, 2009 – Maybe I spoke too soon in my last post about the fate of Data Domain when I opined that it was a done deal and that the dedupe darling would go to NetApp in spite of EMC’s bid (see “Stick a fork in Data Domain” ).
I speculated that NetApp would win out because (a) Data Domain is a better fit for NetApp than it is for EMC and (b) NetApp’s and EMC’s offers were the same: $30 per share. Not true. EMC’s is an all-cash offer and NetApp’s is a combination of stock and cash. And therein lies the reason why EMC could win: If you were a Data Domain shareholder, wouldn’t you want the all-cash deal?
Of course, there’s still the possibility of EMC or NetApp upping the offer, and investors seem to think that’s what will happen. (Data Domain shares closed at $32.58 today, virtually unchanged from last Friday.) Or NetApp could switch to an all-cash offer.
The latest development in this saga: Today, EMC chairman, president and CEO Joe Tucci sent an open letter to Data Domain’s employees (note: employees, not shareholders) trying to woo them over.
You can get additional details at EMC’s site, but here’s the text of the letter:
An Open Letter to the Employees of Data Domain
We at EMC have the highest regard for the people of Data Domain. You have built a terrific company. We know this because we have closely followed your fast-paced growth and progress for years. We understand the contributions your deduplication technologies and solutions are making to companies around the world. You have a well-earned reputation for attracting skilled storage professionals who excel at innovation. And we admire how uncompromising you are in caring for and serving your customers. In many ways, you remind us of EMC.
For these reasons and many more, we believe that bringing Data Domain into the EMC family would be the best way for you to continue building your careers and accelerating the success you've already achieved in the marketplace.
As you know, your Board of Directors has a fiduciary responsibility to do what is in the best long-term interests of Data Domain's stockholders. Looked at purely from a financial perspective, EMC's $30 per share all-cash tender offer to acquire all of the outstanding stock of Data Domain remains superior to NetApp's part-stock, part-cash offer. But of course there's more to the success of a merger than money can ever account for.
Therefore, we imagine that you must be asking yourselves, what kind of future could I expect to have as a member of the global EMC family? The short answer is a great and exciting future-and here's why:
For starters, EMC is a lot more than just the worldwide market and technology leader in storing, managing, protecting, and securing information-or, as we describe it, information infrastructure. We are also a company that truly knows how to acquire companies that have become leaders in their market segments, integrate them smoothly and successfully, and then empower them to excel. We have learned by doing, and our track record is considerable. For example, over the past six years in the Silicon Valley area alone, we have acquired 11 companies, and today we have about 6,000 employees in the region. We are very mindful of culture-respecting and preserving the various cultures that made the companies we acquired successful in the first place. In nearly every instance, after joining EMC, these businesses have grown faster, advanced the development of their technologies more rapidly, reached more customers, and provided greater career opportunities for their people than they had been able to do on their own.
One reason we've been successful is that EMC does not just have one culture but many, with common characteristics like respect, commitment to customers, and passion for innovation and winning. EMC doesn't acquire to consolidate. We acquire growth companies with great people and innovative technologies, and we invest in accelerating their success while their cultures continue to grow and develop. Many of the people in these companies have gone on to leadership positions in EMC, and we would expect the same potential from the talented people at Data Domain.
Our plan is to keep the people and products of Data Domain intact and operate your company as a product division within EMC. Your target-based deduplication technologies are important to the future of enterprise IT. We plan to invest in Data Domain and grow the business and the innovation even more aggressively because of our broader global reach and size.
How would you as an individual and your company benefit from EMC's resources and commitment to leadership? Not only are we deeply committed to our people and their development, we also have by far the largest storage-focused R&D budget in all of IT, which ensures a product-development pace that enables us to derive the vast majority of our revenues from products that are less than 18 months old. We are a truly global company offering opportunities for international experience, as nearly half of our employees work outside the U.S. We have consistently been ranked among the top global companies for training and development. We have a global sales and marketing organization of about 9,000 people in more than 400 locations around the world, complemented by a partner ecosystem that amplifies our strength, value proposition, and market reach. And we have ample cash and a very strong balance sheet to fund an exciting future.
Our collection of considerable strengths-along with our proven experience in successfully acquiring companies and empowering them to greater heights-should provide assurance that EMC can grow and develop Data Domain more rapidly and effectively than NetApp can.
At the end of the day, companies are really about people-committed, talented, passionate people who want to be challenged, who want to invent and create, do something meaningful and lasting, realize their full potential, make a positive impact on their communities and the world, and have fun doing it. That's exactly what EMC is about. The people of EMC are passionate individuals who get involved and make a difference in the lives of our customers and our communities every day. We stand for putting our customers first, treating people with respect, collaborating smoothly with our colleagues and partners, thinking creatively to solve problems, leveraging our diversity, and maintaining a fully inclusive workforce. And we stand ready to welcome the talented people of Data Domain to EMC with open arms.

Stick a fork in Data Domain
June 5, 2009 – Ah, the perils of blogging about an unfolding story. In case you missed it, data duplication darling Data Domain appears to have accepted NetApp’s revised acquisition offer, following EMC’s hostile bid, which followed NetApp’s original bid. See Kevin Komiega’s blog, “Data Domain sides with NetApp,” for the latest news on this intriguing saga.
For reasons that aren’t entirely clear to me, both suitors are offering $30 per share yet NetApp’s deal has been valued at $1.9 billion and EMC’s was valued at $1.8 billion. I guess that has to do with the fact that NetApp’s is a cash-and-stock deal and EMC’s is a pure-cash deal. Which also explains why EMC honcho Joe Tucci considers his company’s bid to be “superior” to NetApp’s.
I think the saga is over, with Data Domain going to NetApp, but some financial gurus think EMC will up the bid even higher or, less likely, that a third suitor (Hitachi?) will appear.
The continuing surge in Data Domain’s stock price – to $32.51 today – suggests that investors expect an even higher bid, presumably from EMC.
Some bloggers have speculated that EMC never really wanted Data Domain, and that EMC made its offer just to drive the acquisition price up and stick it to NetApp. Does anybody really think that EMC is that frivolous? On the other hand, does EMC really need yet another deduplication option?
One problem with scenarios like this is that they set the blogging world on fire, with rampant guessing on what EMC (or NetApp) will do if it loses, or drops out of, the bidding war. Acquire another deduplication vendor? (FalconStor? Ocarina? Storwize?). I doubt it.
What has me scratching my head is the size of this deal: almost $2 billion (or more if the bidding war continues) for a technology that is a feature, not a market. Not to mention a feature that some vendors (NetApp and EMC) give away for free. How much margin will there be in this space once users expect the technology for free, or at least very inexpensively?
And just how popular is data deduplication? Sure, I’ve read all the (vendor commissioned) surveys that suggest that deduplication is the hottest technology in the storage market.
However, consider this: Apptio, which provides IT cost-optimization services among other things, is about to release the results of an end-user survey that says that storage is the next place IT organizations will analyze for cost savings. About 38% of Apptio’s customers are looking to reduce storage-related costs (which seems to me like an awfully low percentage). Of those companies:
--Almost 80% are analyzing tiered storage
--43% are analyzing low-cost archiving and backup options, including cloud storage
--And only 15% are considering data deduplication
According to Apptio’s PR agency, the company will be posting the full results of the survey on its Lean IT blog in the next week or so.

FCoE: The battle lines are being drawn
June 1, 2009 – From an end-user perspective, the battle for the brains (switches and adapters) of next-generation converged networks probably won’t heat up until at least next year. But from the vendor side of the fight, the battle lines are being drawn today.
In a storage-myopic view (which I’m usually guilty of), this could appear to be a battle between storage stalwarts such as Emulex, QLogic, Brocade and Cisco. Obviously, these vendors have an advantage on the Fibre Channel side of the equation. But if Fibre Channel over Ethernet (FCoE) prevails, the converged network of the future will be just as much, or more, of an Ethernet play.
In addition to younger companies that specialize in 10Gbps Ethernet (10GbE) adapters and are fervently working on FCoE – such as Chelsio and Neterion – keep your eye on the leaders in the Ethernet (including 10GbE) adapter market – Intel and Broadcom.
Which brings me to the latest turn of the screw in the Broadcom-Emulex acquisition saga.
I’ve blogged previously about this hostile takeover bid. See
Broadcom makes hostile bid for Emulex
Emulex to Broadcom: “Take a hike”
Most recently, Broadcom took its offer beyond the Emulex board, straight to the shareholders. In response, Emulex sent a letter to its stockholders urging them not to tender their shares, and not to consent to Broadcom’s related solicitation, which aims to ultimately remove Emulex’s entire board of directors and appoint in its place nominees hand-picked by Broadcom.
Until this acquisition clears up, or a white knight rides in, it may be too early to handicap the players in the FCoE space. But who do you think will prevail? If you don’t want to respond below, shoot me an email at daves@pennwell.com.

NetApp + Data Domain: Overlap is ok
May 26, 2009 – Even after a long holiday weekend, the industry continues to debate the wisdom and ramifications of NetApp’s proposed acquisition of Data Domain. For our news coverage, see “NetApp shells out $1.5 billion for Data Domain.” And for reaction from analysts and competitors, see Kevin Komiega’s blog post, “NetApp’s competitors take aim at Data Domain deal.”
I agree with the general consensus that, in today’s economy, NetApp may have overpaid. (The buyout price was $25 per share, about a 40% premium over Data Domain’s closing price prior to the announcement.) But I disagree with some of the other commentary.
For example, some analysts, such as Wikibon.org’s David Vellante, predict that the “vision will take forever to execute.” If this was the same technological hurdle that NetApp faced with its acquisition of, say, Spinnaker, I’d agree. But it isn’t. In fact, they don’t even have to integrate the NetApp and Data Domain deduplication technologies.
Which brings me to another commentary on the deal; namely, that there’s overlap between the two vendors’ data-reduction product lines. Yes, there’s overlap, but that doesn’t mean that NetApp will have to jettison any products.
In the classic situation of product overlap after an acquisition, the conventional wisdom is to eliminate the overlap. But in this case it’s just another option for customers. In the case of data reduction for secondary or nearline storage, customers can opt for NetApp’s free dedeuplication technology, or, if they want higher performance or reduction ratios they can pay for the Data Domain technology. NetApp wins either way.
I don’t see any reason to kill product lines, so the product overlap objection seems to be a moot point. In fact, customers won’t even have to choose between the two product lines because they can be used in conjunction with each other.
Obviously, NetApp has to continue to branch out if it wants to be competitive with EMC, IBM, etc. What’s debatable is whether data deduplication (or data reduction in general) is a significant technology in the larger IT battle. I don’t think it is (because, as many have observed, it’s a feature and not a market), but to the degree that NetApp is right – that data deduplication is a linchpin technology -- the Data Domain deal is a good strategic move.

StarWind offers free iSCSI software
May 21, 2009 – iSCSI’s value proposition has always been lower cost than Fibre Channel SANs. StarWind Software is taking that value proposition to new levels with a free version of its iSCSI target software.
Free iSCSI isn’t new. Most of the iSCSI initiators are free (including Microsoft’s) and a few vendors offer free iSCSI target software. However, most of those are limited in the number of iSCSI connections you can have and/or the amount of capacity supported.
In contrast, StarWind’s free iSCSI target software supports an unlimited number of iSCSI connections and an impressive 2TB of capacity.
Of course, you don’t get StarWind’s thin provisioning, CDP, snapshots, mirroring or replication functionality for free, but unlimited connections and support for 2TB is a great deal. The software installs on any 32-bit or 64-bit Windows server, and turns the server into a shared storage SAN device.
But wait, there’s more. The software supports virtual server environments such as VMware ESX and ESXi (and can run inside a VM) and Microsoft’s Hyper-V, as well as server clustering.
To grab a copy of the software, visit the StarWind iSCSI Target Free Version Download Site.
For those not familiar with StarWind: The company has been selling its iSCSI software since 2003, and claims to have more than 1,000 customers that paid for its software and more than 15,000 that have downloaded a previous free version (which only supported 2GB of capacity).

Disk drive/array market getting SASsier
May 18, 2009 – I just got the most recent disk drive shipment projections from IDC, and I was surprised – not only at the rapid ascendancy of SAS but also the rapid demise of Fibre Channel drives.
For example, if IDC’s projections hold up, SAS will account for a full 50% of all enterprise-level drive shipments this year. The rapid growth of SAS comes at the expense of Fibre Channel, which is expected to account for only 19% of drive shipments this year. Enterprise-class SATA drives are expected to make up the remaining 31%, according to John Rydning, IDC’s research director, hard disk drives (HDDs).
And by 2012, IDC estimates that Fibre Channel will have a mere 1% market share, compared to 25% for SATA and 74% for SAS.
“Fibre Channel will continue in small volume after this year, mainly for existing systems that will continue to sell in 2010 and for aftermarket support of current installations,” says Rydning.
He expects next-generation (6Gbps) SAS to further spur adoption of SAS drives (6Gbps arrays are expected near the end of this year), as well as “capacity optimized” drives with native SAS interfaces.
Personally, I don’t think Fibre Channel drives will bite the dust quite so rapidly, but I don’t have access to the raw shipment figures that Rydning does, and he’s been pretty accurate at predicting these things in the past.
I was just surprised at the SAS projections because I still think of SAS as the new kid on the block.
