So far our posts on reactions to the newly proposed FCoE standard have drawn quite a discussion. Adding to that discussion last week were two stories by Senior News Writer Nicole Lewis on our sister site, SearchStorageChannel.com, which detailed response to the proposal by iSCSI vendors and resellers. The first story, iSCSI vendors: Fibre Channel over Ethernet (FCoE) proposal is purely defensive, from April 17, highlights also that the ANSI T11 standards body has also heard arguments for a slightly different “Fibre Channel over Convergence Enhanced Ethernet (FCoCEE) standard”.
The second, posted this week, is a two-part point-counterpoint Q & A with Doug Ingraham, Brocade’s senior director of product management, and John Joseph, EqualLogic’s vice president of marketing. Ingraham argues FC and iSCSI are still going after different markets; Joseph comes out swinging with the statement that “this announcement means Fibre Channel vendors are planning to get rid of the FC wire, but are keeping the protocol, which is hard for customers to implement and manage, but preserves vendors’ high-margin equipment, professional services and peripheral sales.”

As expected, Overland Storage has been forced to make some drastic cuts in the wake of losing two major OEM customers: HP and Dell. The company announced it has laid off 54 employees, or 14% of its workforce, in the second round of job cuts. Here’s a story that includes a response from the CEO on how the company hopes to pick up the pieces.

Replication tips from JPMorgan-Chase session on DR
JPMorgan-Chase vice president and senior architect Dmitri Ryutov (who pointed out his initials are DR) said one of his business units recently decided on asynchronous replication with guaranteed write order as a compromise between the performance hit associated with synchronous replication, the cost associated with multi-hop and the potential for error with asynchronously replicating highly active databases. However, Young, who is using EMC Corp.’s SRDF-A between two sites 160 miles apart, warned that at the secondary DR site regular point-in-time copies are necessary, because a lost WAN link will destroy the write order—something other users in the session said they were glad they learned.
Another user in Ryutov’s session said an under-addressed issue when it comes to wide-area disaster recovery is compliance with international regulations. The user cited Chinese restrictions on Web content, which a traditional open WAN link for replication may violate, and said he hasn’t yet found a tool that adequately addresses this issue.
Finally, another attendee at the session pointed out that users frequently forget to factor in telco costs in a disaster recovery plans. JPMorgan-Chase’s replication plan, a seven-figure deal for hardware and software according to Ryutov, probably also includes as much as $50,000 a month in telco costs for the four 1 Gbps WAN links between the financial giant’s two sites, the attendee estimated.
UK email archiver zips into US market
British email archiving company C2C, which was working the press briefing circuit at this year’s show in the hopes of drumming up interest in the US market, incorporates an interesting data-reduction feature into its archiving software—the software zips and unzips every attachment in the archive automatically as it stores messages, and can also be used to zip attachments in existing archives.
Data integrity initiative
Oracle, Emulex, LSI Logic and Seagate were briefing journalists in their hotel suite about the new Data Integrity Initiative, which will see each of the vendors add the T-10 Data Integrity Field (DIF) standard—a checksum algorithm that adds 8 bits to each block of data—into their silicon. The companies will be demonstrating and promoting an end-to-end DIF package consisting of each of their products, but say there are no plans as yet for a bundled product offering. Each said that T-10 DIF will become a permanent part of their product lines. Products are expected next year.
The big picture
An emerging trend in the storage industry—if this year’s show is any indication–is a growing shift from current, technology-only discussions to matters of global and long-term impact. The discussion on energy efficiency that began Monday carried into Tuesday’s keynotes, in a talk given by IBM VP of system storage Barry Rudolph. “Energy savings has gone from a recommendation to a mandate,” he said.
Cora Carmody, Chief Information Officer for Science Applications International Corporation (SAIC) also gave a speech that tied the Book of Revelation together with the future of technology. Carmody predicted that “personally addressable humans” would be connected to “presence awareness” systems—an example is a kitchen that starts cooking dinner when your car is a certain distance from home. Most interestingly, though Carmody dismissed the concept as superstition, she acknowledged that bionics—computerizing the human body—are believed by some to be the “Mark of the Beast,” a permanent bodily device required to do business in a global economy brought about by the Antichrist and a precursor to the apocalypse detailed in the Biblical Book of Revelation.
A little bit off the beaten path, maybe, but more evidence that the storage industry is starting to look outward and forward.
Another SNW trend: 51 percent of respondents in the main ballroom Tuesday morning voted in a poll that server and storage virtualization was the fastest-growing priority in their IT shop; implementing an information-based management strategy came in second at 28 percent, and service-oriented architectures scored third with 20 percent.

As I continue to delve more deeply into next generation data protection technologies, I continue to talk to users about their experiences. Of these technologies, there are always some that users find more relevant than others and with no technology does that seem more true than with backup deduplication.
Granted, users that I interview for the different columns and articles I write are often supplied by the vendors so they are certainly not going to provide examples of users with failed installs of their products. Also users who do agree to do interviews often put their best foot forward to put their experience in the best positive light since no one wants to go on the record sounding like they made a bad decision. But having worked as an end-user, I can usually tell pretty quickly by the tone and inflection of a user’s voice how much of their experience is genuine and how much is contrived.
And what I am hearing – and maybe more importantly sensing – from those employing deduplication is that it is working as well as vendors advertised – at least in SMB and remote office environments – and in some cases, maybe better. Too often I find vendors exaggerate the benefits of specific technologies but in talking to users employing deduplication I don’t sense that is happening here.
When talking to users about their deduplication deployment using either backup software or VTL products, they seem genuinely content. While admittedly every one has had some issues, none appear beyond the scope associated with the deployment of any new product and certainly pale in comparison to the ones they encountered on a daily and weekly basis with their previous tape based approaches.
Most users simply sound relieved that they have had success in dealing with their daily backups and can now finally begin to turn their focus to more importang strategic initiatives like performing tests to ensure they can recover their data and offsite disaster recovery. And while the user experiences and emotions I am discussing here certainly shouldn’t translate into anyone into going out and buying a backup deduplication product, I think it certainly merits one taking a closer look at this class of technology.

It’s a dirty job working in this kind of environment,
but somebody’s gotta do it…
Propellerheads and communication
Among the sessions at a new professional development track being tried out at SNW this year was a talk entitled “Interpersonal Communication Skills for Propellerheads” led by Deborah Johnson, CEO of Infinity I/O. As far as we could tell said propellerheads, some 30 in all, didn’t object to the moniker.
Johnson addressed attendees about other humans using their native language, i.e. technical jargon, telling her audience that interpersonal communication requires the befuddled propellerhead to “assess the ‘map’ of the person you’re talking to—” similarly to how they’d map a drive, we surmise. “Understand your goal and the audience context to select the right channel for your communication,” Johnson told the group, approximately one-third of whom were thumbing away busily on Blackberries or typing on laptops.
“Sometimes it takes more than one communication event to get your message across,” Johnson continued, further encouraging attendees to “ask questions to ensure you are decoding messages correctly [from others].”
So was it useful? “I do need to work on my communications skills,” said one self-professed propellerhead, adding that he has recently begun to cut his emails down from several pages to a strict one-page limit. Oy vey!
Deep dive on dedupe
An early session on deduplication turned into a standing room only event, with Curtis Preston, VP of data protection services at GlassHouse, a.k.a Mr. Backup, holding court on the topic. He went through the different products, in-line versus post-process and the different schemes for identifying redundant data. But two points really stood out. First, data deduplication products are currently only appropriate for small to medium-sized environments, he said. “Do not take a 100 TB Oracle database and throw it at a data dedupe.” Second, ignore all the claims about deduplication ratios. “Your data will dedupe very differently to the guy next to you,”
Talking to a couple of users after the session, one thought dedupe could go the way of CDP. “It’s the big topic this year but we’ll see if it’s still around next year,” he said. Another user, with 800 TBs to deal with, said the economics were too good for this technology to be a flash in the pan, if, and that was a big if in his mind, the products are robust and scalable enough. He noted that’s FalconStor’s SIR (single instance repository) doesn’t ship in volume for another couple of months, so it’s still very early days for this technology.
Users feeling out file virtualization
Comcast Media Center manager of server and storage operations Paul Yarborough gave a talk Monday afternoon on his company’s decision to virtualize NetApp 3020 filers with Acopia Networks’ ARX switch. Another presenter on file virtualization, Stephen Warner of Quest Diagnostics, has also deployed Acopia, to virtualize EMC Celerra boxes. Some tidbits that arose out of the presentations:
Yarborough’s company was so strapped for space on the NetApp filers due to the 16 TB filesystem restriction that they were spending dozens of man-hours on a regular basis reingesting digital content that had been deleted from overutilized disk.
Meanwhile, Yarborough said he evaluated NetApp’s OnTap GX as a means to solve the filesystem limit, but he remained pointedly noncommittal on his findings, saying only that it was a very new product when he evaluated it.
Warner, who heads up an EMC shop, said he believes that truly vendor diagnostic virtualization will not come from a large vendor. In Acopia, he said, his company found a startup it could influence (of course, it helps to have just under a petabyte of data under management if you’re looking to influence other companies).
Other users’ questions during Yarborough’s session were as interesting as the presentation itself. During the Q&A users peppered Yarborough with questions about performance impact, how much training it had required to get his staff up to speed on the Acopia product, and whether or not Acopia was truly effective in virtualizing Windows and Linux systems equally. Yarborough answered that there had been no performance impact that he’d seen, that training on the Acopia switch had taken a little longer since it operates on a switch and his admins are not used to managing switches, and that yes, Acopia is effective in virtualizing heterogeneous OSes.
Another user questioned the fact that Comcast had installed an Acopia agent on its domain controller. “That would never fly in our environment,” the commenter said.

Data storage management
First Intel. Now the White House. We’d love to know what, if any, email archiving products these guys are using. And we don’t know what’s worse–if they have implemented archiving procedures, or if they haven’t.

Storage protocols (FC / iSCSI)
Two of the storage industry’s most prolific (and diametrically opposed) bloggers have posted–as one would expect–lengthy and diametrically opposed blog posts about the announcement this week that storage vendors are proposing a new Fibre Channel over Ethernet standard (FCoE).
Chuck Hollis of EMC writes that Fibre Channel over Ethernet will rectify ongoing concerns with iSCSI related to (you guessed it) reliability and performance. (Hollis also wrote a post a while back questioning whether iSCSI is really going anywhere.)
Meanwhile, on Drunken Data, a blog belonging to DR expert and maverick analyst John Toigo a commenter dismisses FCoE as pure marketing fluff from FC vendors desperate to hang on to market share. “In my view,” the commenter writes, ”FCoE [follows] the rule, ‘If you can’t beat them, join them; if you can’t join them, confuse them.’”
You couldn’t find two more different viewpoints–neither writer even shares the same basic premise about the status of FC in the market in general. As always, reality is probably somewhere in between.
FUD reigns supreme when it comes to the various new standards being proposed for Fibre Channel these days–those not participating or opposed to the standards efforts like to paint them as last-ditch ploys by FC vendors to retain market share. Supporters of the standards, however, make compelling arguments for a future of converged networks and multiprotocol systems for all. Unfortunately, aside from one analyst (Brian Garrett of ESG, quoted in our news story on the new FC-SATA spec being touted by Emulex), all the supporters of the specs we’ve talked to so far are Fibre Channel vendors.
The bottom line: the proof is in the pudding. We’re not ready to declare the standards unadulterated marketing fluff, but we’re not seeing multi-lateral industry support for any of them, and we’re certainly not seeing any storage end-users, integrators, resellers or consultants–in other words, anyone who ever actually works with storage products–being asked for their opinion by any of the standards committees.

Like many in the storage industry, I keep wanting to declare tape is dead, or at least on its last legs, when it comes to data protection. I surely thought the triple whammy of emerging technologies like deduplication, asynchronous replication and removable disk cartridges were going to finally drive the nail through the heart of tape.
I couldn’t be more wrong. Last week, I had an insightful conversation with the president of a records management firm based in New Jersey which has, for years, serviced high-end customers like financial services and pharmaceutical firms in the Northeast. They also anticipated more of their clients replicating data to them and, for years, reserved space on their floor for disk for this purpose. Instead, they are installing more racks to hold tape and don’t foresee disk happening at all or not nearly to the scope they foresaw years ago.
They are finding that even though clients want or do replicate data, they also find users on the high end of the spectrum want control of the data in its useable format. Once replicated, users spin it off to tape and store it long term with them for long term archival and data recovery under potentially catastropic circumstances. They want the records management company to know as little about the data they are sending them as possible, and they want the data stored in a format inaccessable to anyone but the user. This is a trend that bears watching in the tape market for even as disk cartridge, deduplication and replication technologies take off, new reasons to keep data on tape are emerging.

FAN or File Area Network is the latest buzz word for file virtualization, coined by Brad O’Neill, senior analyst at The Taneja Group. (He has some big clients in this space.) In June 2006, O’Neill reported that a Taneja Group survey of global IT decision makers, found that 62% of respondents now identify “file management” as either “the top priority” or “one of their top priorities” requiring immediate attention in their data centers. Meanwhile, Tony Asaro, senior analyst at the Enterprise Strategy Group has just posted an interesting blog on the FAN market, or rather what he sees as the lack of one. So which is it? Where have all the FANs gone?
