Another email recovery oopsie

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

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.

Point-counterpoint on FCoE

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

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.

Triple whammy, not enough

Beth Pariseau Maggie Wright Profile: mwright16

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.

Are you a FAN fan?

JoMaitland Jo Maitland Profile: JoMaitland

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?

The uncomfortable marriage of Fibre Channel and iSCSI

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

We received the following comment from a VAR based in Florida on our piece covering the newly proposed Fibre Channel over Ethernet (FCoE) standard:

The concept of FC over Ethernet has very limited value. According to this article, the FCoE consortium is targeting this at low-to-mid range servers, over 10 GbE, and as a convergence technology. While 10 GbE makes sense from the storage array to the switch, it makes little to no sense from the server to the switch for two reasons: first, low to mid range servers — where this is targeted, don’t have the I/O requirements to saturate 1 GbE much less 10 GbE, and their PCI busses would not be able to handle anywhere near 10GbE throughput (do the math), and second, the reason that FCP exists is not because of throughput, but deterministic response time, which is guaranteed by the FC protocol wheras the Ethernet protocol becomes more non-deterministic with high load. This lack of deterministic response time will not be fixed with FCoE.

For these reasons, FCoE to the server does not make sense on the low/mid (don’t need the throughput and couldn’t handle it anyway) or the high end (Ethernet lacks the predictable response time of FCP). So back to the question of FCoE over 10 GbE from the storage array to the switch — if the storage arrays were 10GbE capable, why not just use iSCSI, which is already supported and in wide use in the enterprise despite what some manufacturers’ marketing and media reports say? My personal opinion is that this is an effort on the part of manufacturers who are behind in iSCSI to change the game in an effort to compete, and provides little to no value to consumers.

We have the feeling this could develop into an interesting discussion in the industry over the next year or so as FC and iSCSI, originally at odds in the market, have increasingly been combined in tiered storage environments and multiprotocol systems. Still, combining the two protocols–especially in the same data stream–could become a thorny issue.

What do you think?

Vista to make WAN optimization a thing of the past?

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

TechTarget’s networking reporter Andrew R. Hickey wrote an insightful piece on WAN optimization technologies embedded in Microsoft Windows Vista and Longhorn Server and how they could make separate WAN optimization boxes obsolete:

Vista and Longhorn contain redesigned TCP/IP stacks, quality of service (QoS) facilities, file systems, security systems, and WAN-friendly presentation layers for applications…TCP flow control and error recovery have been improved while remaining compatible with other TCP implementations… Microsoft has enhanced management control over QoS, meaning that network administrators might be willing to trust QoS markings from Windows machines. In addition, the native Windows file-system access protocol, CIFS, has been improved and will work with most existing applications without requiring program changes. Also, remote application delivery systems, like Windows Server Terminal Services or Citrix Presentation Server, will probably have their performance enhanced when applications are rewritten to use Vista’s Windows Presentation Foundation component.

Before you go chucking your Riverbed box out the window, though, there are a few caveats:

Vista’s security improvements interfere with some VPN clients, and certain security options could interfere with existing WAN performance or optimization products unless they’re disabled. Data-reduction compression done by external WAN optimization tools may still be very useful in some situations.

[...]

Enterprises should use caution and examine how compatible Microsoft’s technologies will be within their networks, according to Gartner.

“Windows Vista and Longhorn offer the promise of improved networking performance and security,” Gartner stated. “However, the scope and scale of the changes present significant security and compatibility risks. Most enterprises will delay large-scale deployments until after application compatibility has been verified, which Gartner expects to take 12 to 18 months. This will give networking components time to mature…. As a result, the benefits of the new Windows communications stack will not be broadly realized before 2009.”

For now, maybe try tossing a TV off the roof instead.

Unstructured data management podcast

Karen Guglielmo Karen Guglielmo Profile: Karen Guglielmo

Unstructured data is… well, it’s unstructured. Unruly, even. Unbearable? Well, maybe that’s a bit too much, but it’s definitely hard to deal with. Word documents, email, images and MP3s, among other types of files, are crowding storage systems at an exponental rate and classifying this data can be very difficult. Analysts note that 85% of data in a typical enterprise is considered unstructured, and managing all of this data is a growing concern for many enterprises.

In this podcast, Pierre Dorion offers practical answers to the most common questions about unstructured data management he hears from storage pros today.

Mimosa gets funding, hints at new products

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

It’s not quite a product announcement yet, but it’s worth noting here that the friendly folks at Mimosa say they’re going to use a new $17 million in Series C funding in part to launch two new products before the end of the year. The email archiving company, which claims 160-plus customers, says it’s going to add filesystems to the applications its NearPoint archive will support, which currently include emails, instant messages, and IP-based voicemails. The file archiving will be available this summer, according to TM Ravi, CEO. According to Ravi, SharePoint archiving will follow by the end of the calendar year.

Mimosa has amassed $34.5 million in VC funding since its founding in 2005, and had its first full year of revenue in 2006, but Ravi says he’s already thinking IPO. He was mum on the timing but said “the traditional venture-capital goal is to go public, and that’s our goal as well.” He added, slyly, “But if along the way someone makes an offer we can’t refuse…c’est la vie.”

Google responds to “gotchas”

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

On March 22, we posted a Q & A with Burton Group analyst Guy Creese about potential “gotchas” for companies considering Google Apps Premier Edition. Recently, we heard back from Google Enterprise product manager Rajen Sheth in response to Creese’s analysis.

Storage Soup: Guy Creese pointed out that Google partners with Postini for email archiving, but doesn’t offer archiving for documents and spreadsheets Do you plan to offer document archiving as well?

Sheth: I think we actually have a better story than what’s typically done with documents. Within an enterprise, documents are all over the place–they might be sitting on your laptop, they might be sitting on a file share somewhere, they might be in your email. What we provide is one central place that people can access [files]. If I want to search through all the documents I’ve ever made or gotten, I can just do a Google search on Docs and Spreadsheets.

In terms of bringing it out of Google’s repository, there are a couple of things that can be done. Number one, we allow the export of files in multiple file formats, and the second thing is we offer an XML API, which means you can access that data through XML and pull it out to a records management system or any other system, really that wants to leverage that data.

Storage Soup: Does that mean Google has no plans to get into that kind of records management or archival space?

Sheth: No. We consider ourselves a user collaboration package rather than a records management package, but we want to integrate with records management and email archiving systems people already have.

Storage Soup: What about the point Creese brings up about keyword search vs. some of the records management searches with other products–is that something Google might bring into Docs and Spreadsheets for retrieval?

Sheth: On a separate side of the business we offer clustered searches and taxonomies through Google Search Appliance. There has been some talk about offering that through these products, but what we’ve found with user studies, both with consumers and in the enterprise, that collaborative tagging of documents for future retrieval is more popular. People rarely do more than type in a couple of keywords–we’re working on a variety of things on our search capability where the front end remains the same, but on the back end we do the heavy lifting to figure out what people want.

Storage Soup: Creese said that “[Software as a service (SaaS)] companies will eventually get to the point where they can’t save everything. Even with storage prices dropping, as more and more corporations put their data into software as a service there’s going to be a tipping point coming, where either it starts to become expensive to save everything for the service and the service therefore raises its rates, or it’s just too difficult to find what’s there.” What’s Google’s response?

Sheth: I actually disagree with that. When we provide 10 GB [in Gmail inboxes] we’re doing that with the knowledge that we can serve that and serve that well at the price point that we’ve offered. There are things that are unique about how Google structures its data centers–we use commodity PC servers within our data centers and many of them to bring down storage costs, rather than large back end storage systems. So as a result of that I think we can serve storage for a much lower cost than most organziations are able to. So when we put out a package like this with a certain storage quota we do it with every intention that users will use that storage to the absolute hilt.

We’re already running millions upon millions of consumers on these services–in terms of scalability, we’ve already scaled the services to support many users. We’ve also already tested it with a large company–ourselves.  Our users are very, very heavy email and document users, and we use our own systems, the same ones we have for our customers. We essentially battle-tested it to make sure that it could handle the load.

Storage Soup: Yahoo announced yesterday that they’re offering unlimited storage with their email. Is that where Gmail will go eventually?

Sheth: I think we’d go in a little bit different direction. What we’re focusing on is that when we give you a quota, we want to give you a variety of ways to use that quota, including large attachments. We want to offer a variety of ways to use that Gmail quota appropriately–provide very high quotas and provide more tools to use that storage.

Storage Soup: What’s Google’s response on Gmail’s limits on sending emails out to no more than 500 people per day?

Sheth: The issue that we have is that we want to protect our users from spammers. We don’t want spammers to use Gmail, whether it’s the regular edition or the premier edition. We also don’t want Gmail users receiving spam. That said, there is the need for the ability to deliver to multiple sets of users. A lot of organizations already have these mailing lists set up and can use them [with Gmail]. Over time, we see other parts of our product portfolio as candidates to help solve these types of problems. For example, we have a product called Google Groups, which provides the ability to have larger groups and group page, and it’s something people can use right now, and we consider it a good candidate to bring into the [Google Apps] platform down the road as well. We have groups with thousands and thousands of users.  

Storage Soup: Creese also points out that Google lacks an equivalent to PowerPoint in your productivity suite.

Creese: My response to that is we’re definitely not trying to duplicate Microsoft Office. The way I would think of it is that Office is very well designed for individual productivity–an individual preparing something to present to a group of people. We’re focusing Google Docs and Spreadsheets on collaborative use case scenarios.

Here’s an interesting ancedote from a user requesting more storage at his company and likening the process to buying a car.

At least storage guys don’t wear those nasty shiny suits…
