NetApp previews new GUI

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

NetApp chief technical architect Val Bercovici let slip on his blog that NetApp is planning a new interface for Windows users of NetApp filers, complete with screenshots and feature details.

The preview is in the second half of Bercovici’s post about an award NetApp won at VMWorld Europe. Apparently the judges deducted points for the management interface, so Bercovici responded with the big reveal of what’s coming soon.

…our newest customers or partners evaluating and deploying their FAS arrays one or two at a time also deserve a modern interface to help them come upto speed. In the 21st century, that interface is most commonly provided by an administrative workstation running Microsoft’s Windows GUI… NSM [NetApp System Manager] using the familiar Microsoft Management Console (MMC) interface with a clean and modern Windows 2008 Server look & feel.

He also includes a screencap of what the interface will look like, pointing out how systems are listed in the navigation tree with active-active pairs grouped together along with a list of their software services. NSM also integrates with the Windows System Tray to pop up ‘bubble alerts’ for health issues with the arrays, snapshot management, and auto discovery for authentication systems like Active Directory, among others.

Existing enterprise NetApp users say it probably won’t have much impact on their environments. “In general, a GUI is a sexy tool, that all vendors like to demonstrate but a “real/old fashioned” system engineer will use it not very often,” wrote Reinoud Reynders, IT manager for the University Hospitals of Leuven in Belgiumin, an email to Storage Soup. “For vendors, it’s very important that they have one (for pre-sales activities), but after that, the use is less important.”

More musical chairs: EqualLogic exec changes roles within Dell

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

One of the public faces of EqualLogic has a new role within the company that acquired it, Dell officials confirmed today.

John Joseph, formerly VP of marketing for the iSCSI SAN vendor, has been shifted to a new position as Vice President of Enterprise Solutions Marketing. A Dell spokesperson described the shift in an email to SearchStorage:

John has taken on a new role within Dell focused on integrating solutions. This move comes on the heels of Dell’s recent announcement that it will organize itself around three major customer segments – large enterprise, public sector, and small and medium businesses. John’s move further demonstrates the success of the EqualLogic acquisition and its integration into Dell and the importance of storage in Dell’s enterprise business solutions.

Asked for clarification on what exactly “integration” means, the spokesperson offered further,

The role focuses on bringing our different products together (storage, servers, etc.) and making sure we addressing our customer’s data center needs. So yes, he will still have contact with all storage products as well as servers, services, and software. Customers want a ready tested and certified IT solution from Dell and we’re responding.

So Joseph will still have contact with the EqualLogic products, but it seems to have gotten more remote–or at least more mixed in with other duties. Duties, we might note, that seem a bit removed from his previous role in marketing for an iSCSI SAN platform that Dell positions for SMBs and the midrange. Presumably, enterprise solutions require some high-scale, Fibre Channel activities as well.

More importantly, Joseph was, as mentioned above, a public symbol for EqualLogic and is closely associated with that company and its products. His continued presence at the wheel following the acquisition was one of the more encouraging signs I saw for the Dell/EqualLogic integration.

Musical chairs going on in the storage industry

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Two storage companies have new CEOs today. Hitachi Data Systems promoted its CEO Minoru Kosuge to chairman and picked its COO Jack Domme to replace him.

Meanwhile, Fusion-io, (the topic of plenty of coverage yesterday) has more quietly replaced its CEO, Don Basile, with its former senior vice president David Bradford.

Fusion-io didn’t officially announce its CEO change, but quoted Bradford and identified him as its CEO in a Tuesday news release about its OEM deal with Hewlett-Packard. He’s also listed as CEO on their executive bios web page.

Bradford’s bio on the site credits him with persuading Apple co-founder Steve Wozniak to join the startup. This contradicts a published report from Fortune last month which credited Basile with the publicity-generating hire.

I’ve seen this kind of CEO shift happen at other startups as they enter different phases, in this case from developing product to trying to grow revenue. A similar thing even happened during a transition in VMware’s growth patterns last year when Paul Maritz replaced founder Diane Greene. But while Fusion-io is not a publicly traded company and is not required to announce a change in CEO, the storage community on Twitter took notice of the move with some chatter this morning.

Storage end user and blogger Martin Glassborow wrote on Twitter, “The sudden and rather stealth change of CEO is interesting. You wonder if there has been some direction issues.”

StorageIO Group founder and analyst Greg Schulz Tweeted back,  “Concur, some normal shuffling of people moving around, however also some attrition, RIFs, and strategy changes as you point out.”

I’ve been in touch with several people at Fusion-io today to try to get to the bottom of the apparent discrepancy over The Woz, but have yet to hear back.

A technology deep-dive with Fusion-io

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

We interviewed Fusion-io Inc. CTO David Flynn for one of our news stories today–here’s some nitty-gritty bonus footage on how the company’s product goes about protecting data, and how that compares to spinning-disk systems.

Beth: So one ioDrive is 320 GB. Is data striped across all the chips or do you have separate data sets?
Flynn: Each one of the Flash modules looks like a volume and you can either stripe them or mirror them to make them look like one volume. Or is you have multiple cards you can aggregate all of those volumes with RAID 10. We have RAID-5 like redundancy on the chips, then RAID between the memory modules. What we’ve come to realize after we introduced FlashBack is that it actually lets you get more capacity.

Most SSDs are 64 GB at most—32 GB, 64 GB. With this technology we put five to 10 times as many chips within our card. That would increase the failure rate because the individual chip’s failure rates add up. With our ability to compensate, we can get to higher capacities, and with that we can increase endurance, because you can spread the data out.

Internally it’s more like RAID 50 because I have eight die in my redundancy chip. There’s one parity die for each package. It’s 24+1 and then that quantity times eight, because there’s eight of those sets. If you were to line it up like disk drives, it would look exactly like that, 24 disk drives and then an extra one, 8 rows. So when we talk about this as a SAN in the palm of your hand we really mean it, because we’ve taken die within the various NAND packages and arrayed them together just like a disk array. It’s also self-healing in that if you have a fault the system reconstructs the data that otherwise might’ve gone missing and moves it to a different spot and turns off the use of the spot that failed. You don’t have to service it. It automatically just maps it out. Like Xiotech’s ISE product—that’s bleeding edge stuff for disk arrays, and it’s built into the silicon here.

What about double parity protection? That’s all the rage in the disk drive world these days. What if more than one die fails at once?
For us to rebuild and heal takes a split second. Having a second failure during that time is not going to happen. It takes so long to rebuild a disk drive—it can take more than a day now—that the probability of a double failure goes up. The other thing is that disk drive failures are often highly correlated—the drives come from the same batch. They tend to fail randomly but close to each other in time. Our portfolio does cover n+m redundancy as well as N+1 because we anticipate a day when we’re putting not hundreds of these die on the boards but thousands and going into the tens and hundreds of thousands.

At the same time the Flash memory has finite write endurance, so they are all going to wear out at some point. So how do you compensate for that?
We account for how many write cycles it’s been through so we can give somebody a running…like an odometer, for tread wear on a tire. You can go five years or 50,000 miles. We warranty it, and you can swap out the modules without needing a new carrier card. Because we have such high capacity we naturally get a longer lifespan. It’ll last for 5 years even if you’re doing nothing but writing constantly. Wear-out has been overrated I think because most of the failures people are seeing have nothing to do with wear-out, they have to do with internal events that cause chips to lose data.

Like what?
Here’s the four factors. This is the dirty little secret of the NAND world—it’s the newest fab process, which means it has its kinks. It’s the tightest feature size—they’re going to 32 nm. The density of the array of cells is achieved by sharing control lines. And then, fourth, and the real killer, to move the electrons into the floating gate cell it takes 20 volts internally. Most core voltages are well under a volt nowadays.

These four factors mean having a short-out event on one of these tiny little control lines—if you have just one chip it’s no big deal, it’s 40 out of a million. Which for a thumb drive, nobody would notice—it’s more likely to get shorted out in your pocket. But when you put hundreds of them together, now you have hundreds of those 40 out of a million chances to have something go bad, and that actually adds up to be something like one or two percent of these things fielded would have a data loss event. For a normal SSD the way they compensate is to put fewer chips on it or try to sweep the problem under the carpet—what they say if you talk to them is, ‘Well, we screen it very well, we run it in advance to make sure it’s not going to happen.’ You can screen it up front but there’s still probabilities of failure.

Here’s the thing: disk drives wear out, too. The trouble is, it’s unpredictable. One of the strongest motivators to going to solid state technology is the predictability of when you’re going to need to service it. And after a couple of years, you’re going to be able to replace it for a fraction of what it cost initially.

EMC vows to fight DOJ investigation

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Not a month after an Israeli news source reported that EMC Corp. had been under investigation concerning government contracts in Israel, EMC revealed in its annual report filed with the SEC that it’s under investigation by the Civil Division of Department of Justice (DOJ). The DOJ investigation involves “allegations concerning (i) EMC’s fee arrangements with systems integrators and other partners in federal government transactions, and (ii) EMC’s compliance with the terms and conditions of certain agreements pursuant to which we sold products and services to the federal government, including potential violations of the False Claims Act.”

There’s no relation to the Israeli investigation, according to an EMC spokesperson. In another contrast with that case, in which EMC flatly denied comment, this time the company is flatly denying any wrongdoing will be found by the DOJ. “EMC did not make improper payments to business partners and did not violate the False Claims Act,” wrote the spokesperson in an email to “The matters at issue in this case are historical in nature; some of the allegations relate to events nearly ten years old. We will vigorously defend this case and the many years EMC has spent serving the U.S. Government…”

The SEC filing reads,

The subject matter of this investigation also overlaps with that of a previous audit by the U.S. General Services Administration (“GSA”) concerning our recordkeeping and pricing practices under a schedule agreement we entered into with GSA in November 1999 which, following several extensions, expired in June 2007. We have cooperated with both the audit and the DoJ investigation, voluntarily providing documents and information, and have engaged in discussions aimed at resolving this matter without any admission or finding of liability on the part of EMC.

HP sweetens deals during recession

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Storage vendors are announcing new deals in an effort to make their enterprise goods more tempting amid slashed storage budgets. Today, HP confirmed it is extending a 0% financing deal it had previously been offering with its servers to storage.

According to an HP spokesperson, the HP storage products included in this program are:

  • HP StorageWorks Modular Smart Arrays
  • HP StorageWorks Enterprise Virtual Arrays
  • HP StorageWorks All-in-One systems
  • HP ProLiant storage servers
  • HP StorageWorks Commercial Nearline Tape Systems
  • The move comes after HP reported double-digit revenue declines over most of its lines of business for its first fiscal quarter. The Enterprise Storage and Servers (ESS) group was no exception, with revenue of $3.9 billion, down 18%. Within that, storage revenue fell 7%; overall profit for the group was also down 14%.

    HP joined NetApp in reporting earnings declines in a fiscal quarter that included January. (Interesting aside: Dell reported that its storage business, especially its low-end PowerVaults and EqualLogic midrange iSCSI SANs, did relatively well for its first fiscal 2009 quarter, with business up 7% though overall earnings slipped).

    But in a recession this deep, some federal interest rates have also been cut to zero in the hopes of getting business moving again. Housing prices are so depressed that theoretically, they should be affordable to a whole new class of buyers. But neither of those things–and so far, all the King’s horses and all the King’s men–haven’t done much for the markets, if only because everyone who still has a job is so afraid they’ll lose it by the end of this year that they aren’t spending, no matter how good the deal is.

    Many enterprise storage users seem to be in a similar boat–these financing deals, like low home prices, would be irresistible in better times. Ironically, in bad times, they may not be enough.

    Data Domain revs its dedupe engine

    Dave Raffo Dave Raffo Profile: Dave Raffo

    Data Domain is bumping up its deduplication speed with an operating system upgrade.

    Moving from OS 4.5 to 4.6 will improve the speed of Data Domain systems from 50% to 100% depending on the protocol and network interface, according to the vendor’s VP of product management Brian Biles. The greater speed comes from code tweaks in the OS that lets multi-core CPUs support more parallel streams.

    The improvement with OS 4.6 is greatest for systems running 10-Gigabit Ethernet and Symantec’s NetBackup OpenStorage (OST) interface. For instance, max performance for the DD690 – Data Domain’s largest system – goes from 1.4 TB per hour to 2.7 TB per hour for a 90% increase using the new OS, according to Data Domain’s estimates. That’s with 10-GigE and OST.

    Is speed all that important for dedupe? Throughput often gets lost in the debate over dedupe ratios and the inline versus post-processing argument, but analysts and customers say speed is a major selling point for dedupe systems. Speed is plays a big role in Data Domain’s inline deduping, which risks slowing backups because it dedupes while backups are taking place.

    “Faster equals more data processed, which equals more data reduction,” Enterprise Strategy Group analyst Brian Babineau says. “Performance improvement is a means to other benefits, including storing more data in smaller footprint.”

    Rich VanLare, Network Administrator for shopping center developer Regency Centers, has been using a Data Domain DD690 with NetBackup and OST since last October and was blown away by the speed with OS 4.5. VanLare says his goal was to decrease backups to below nine hours, and is down to five hours since replacing tape with the DD690. VanLare says he’ll upgrade to 4.6, but he’s happy with his current system.

    “The box is incredibly fast to begin with,” VanLare said. “Personally I don’t need it [improved speed] because it’s already exceeded my expectations.”

    VanLare, who claims to get more than 90 percent compression, said the OST option was the main factor he choose Data Domain over VTLs from NetApp and Overland Storage.

    “I have a lot of administrators getting into the interface, and I just wanted things to be simple,” he said. “OST tells an administrator exactly what happens if something fails.”

    VanLare biggest concern with Data Domain is he won’t be able to add a second box at a DR site until the economy improves. “I wanted to do that this year,” he said. “With budgets as they are, I’m not sure that’s going to be approved.”

    Online services bite the dust

    Beth Pariseau Beth Pariseau Profile: Beth Pariseau

    Two online data sharing services failed this week — one from a computing giant, and the other a small social bookmarking website.

    That’s the trouble in this wild and wooly world of the cloud–especially in its early days. Not every service is going to make it, and then you’re going to have to figure out what to do with your data if your service fails.

    Hewlett-Packard pulled the plug on HP Upline, and according to our Australian affiliate, ma.gnolia went under. SearchStorage ANZ reports that “in late January, ma.gnolia experienced a catastrophic data loss event and turned to backups to restore its database of users’ bookmarks. Both the primary and secondary backups failed irrevocably.”

    Said a friend of mine who’s a Digg addict (I’m more a woman myself), “Losing my bookmarks would *hurt*.”

    In the case of HP’s Upline online backup service, users will at least be able to get their data back. HP confirmed this afternoon will be discontinued as of March 31. In a statement, an HP spokesperson said:

    HP continually evaluates product lines and has decided to discontinue the HP Upline service on March 31, 2009.

    HP will no longer be backing up customer files to the HP Upline servers as of Feb 26, 2009 at 8 am Pacific time. HP will keep the file restore feature of the Upline service operational through March 31, 2009 Pacific time in order for customers to download any files that have been backed up to Upline.

    Blogger AppScout wrote disappointedly, “And so goes the story of one of the slickest online storage and backup services to launch in the past year.” Among Upline’s unique features was the ability for users to tag content for later search and share, and to publish files online using the service through a feature called the Upline Library. However, Upline crashed right out of the gate, drawing opportunistic marketing for competitors.

    EMC, NetApp clash over VMware

    Beth Pariseau Beth Pariseau Profile: Beth Pariseau

    There are lots of interesting donnybrooks going on in this industry at any one moment, but EMC-NetApp is like the Red Sox-Yankees rivalry: imbued with a sense of historical inevitability, and capable of reaching heretofore undiscovered levels of bickering.

    The latest series of skirmishes takes place on one of the most hotly contested battlefields of storage today–VMware. Specifically, the integration with, support of, and general glomming on to the server virtualziation giant’s software.

    There was a time when I would’ve guessed NetApp was the most-installed storage system with VMware, especially as VMware over NFS took hold at least in some enterprise shops. Server administrators and application admins were already familiar with running databases over NFS, and NetApp’s NFS was generally considered the best. Plus, NetApp has the whole multiprotocol thing going on with iSCSI and NFS in the same system, built in data protection tools, etc.

    Not so, says EMC, triumphantly waving a newly released report from Forrester Research:

    EMC…has been cited as “the most prevalent storage vendor in their overall environments” according to a survey of 124 global IT decision-makers currently using x86 server virtualization technology. The January 2009 report titled Storage Choices For Virtual Server Environments also revealed that 98 percent of the 124 survey respondents were using VMware ESX in their virtual server environments, and that 78 percent have virtual server technology in use for production application workloads.

    According to the survey, 48 percent of respondents chose EMC as their brand of networked storage for virtual servers – nearly two times as many as the next closest vendor, IBM. Additionally, 63 percent of the respondents prefer to buy from a single storage vendor, which illustrates that buyers show a preference for working with a single storage vendor.

    Furthermore, the report states:

    There is little correlation between vendor and protocol selection. Surprisingly, there is not
    a strong pattern linking the choice of vendor to the preferred protocol. Even NetApp, with its
    strong heritage in file storage and ability to offer in-depth best practices for NFS in virtual server
    environments, still shows a prevalence of FC — NFS is the least common option. This is due
    to the following: 1) VMware did not add support for iSCSI and NFS until ESX Server 3.0; 2)
    storage vendors are generally protocol-agnostic — they support and recommend all available
    protocols; and 3) customers are often unwilling to diverge from what they know and use already.

    This is also the case when it comes to storage vendors in general–companies generally don’t buy new storage systems or try new technologies just for to support VMware, the report finds. More than half (53%) of the users surveyed were using EMC. That’s a much higher EMC sample than the 28% networked storage market share EMC had in the most recent IDC’s quarterly storage report.

    Besides the disproportionately high number of EMC customers surveyed and relatively small overall sample of 124 users, the Forrester report also discloses that “in terms of industry, financial services and insurance is the most prevalent, with 41% of respondents.” Both of those verticals tend to favor EMC.

    According to Forrester’s survey, 25% were using IBM with virutal servers followed by NetApp at 24% and Hewlett-Packard at 23%. I’m curious how many of the systems counted as IBM in the study are N-Series, which is NetApp under the covers.

    Meanwhile, NetApp is not pulling any punches, continuing its VMware space-efficiency guarantee, this time extending it, as it did its primary storage data deduplication capabilities, to V-Series. That means it’s essentially offering a guarantee on third party storage from EMC, IBM, HP and Hitachi Data Systems fronted by a NetApp head.

    Not everybody in the industry was impressed with the VMware guarantee. The guarantee is highly conditional, making it highly unlikely that NetApp would ever have to pay off.

    As for applying NetApp services to third-party storage, the Forrester report seems to suggest that most users tend not to have more than one vendor in their environment, let alone attaching one vendor’s system to another’s. Can you imagine the finger-pointing if there were an issue?

    So. We’re left with a relatively-small-sample-size report skewed toward one vendor on one side, and hollow guarantees on the other.

    Oh! And one spoof of the battle scenes in 8 Mile that has to be seen to be believed.

    There’s still a lot more ground to be gained and lost this year in the VMware marketplace, and who knows what events might come along to change the industry completely. In the meantime, though, we know there’ll never be a dull moment between the notorious NTAP and E-squared.
