But with so many new products and alternatives, those excuses just don’t cut it anymore. Lax laptop backup Need for speed TOMORROW, AND TOMORROW, AND TOMORROW” starts the second sentence of Macbeth’s soliloquy in which he laments Lady M’s untimely demise. And for fans of “Jeopardy,” it’s also the answer to the question “When will State of your storage shop implement some real data protection for laptop PCs?” backup dedupe That probably just tacked another violation onto my poetic license, but it’s hard to avoid quoting Shakespeare even when you’re talking about Storage something as non-Elizabethan as data storage. And the “tomorrow” refer- tech evolves ence is pretty accurate if some of the surveys I’ve seen lately are reason- ably accurate. The most recent one to catch my eye is from Druva Software, Virtualize which, as a laptop backup vendor, has just a wee bit of interest in the re- your storage sults. Nonetheless, some interesting numbers turned up in the survey. Among the survey’s 140 respondents, approximately one-third said that more than half of their users were issued laptops as their principal PCs. Backup options for ROBOs But a whopping 62% said a laptop backup policy wasn’t currently enforced even though most claimed they currently have something in place to do laptop backups. Hybrid clouds loom “Those are a couple of pretty big gaps, but the survey goes on to report even more head-scratching results, like the 30% who said they don’t really see a need for a laptop backup policy. Even more perplexing are the 59% Remote backup of respondents who considered themselves “satisfied” with their current under control laptop backup setup. What’s going on here?

You might be OK rolling the dice when it comes to complying with laws that say what data must be preserved, but think about all that corporate IP going unprotected. That’s gonna get somebody’s attention, right? Intel recently described a study it commissioned from the Ponemon Institute in which the number of lost or stolen laptops was calculated for the 329 participating companies. Ponemon’s numbers are staggering—with an average of 263 laptops MIA for each company. Even if your company Lax laptop backup experiences just a quarter of that loss (let’s say 60 laptops with half-filled 200 GB disks), you might be kissing off 6 TB of corporate contracts, proposals, plans, projections and Need for speed budgets each year. A recent study by the The study goes on to put a price Ponemon Institute State of tag of $49,246 on a typical “disap- backup dedupe peared” laptop; again, that seems put a price tag of on the high side as it’s based $49,246 on a typical on just about every worst-case Storage “disappeared” laptop. tech evolves scenario imaginable. Unless your company’s laptop losers are writing patents, putting risky information in the hands of competitors and would-be Virtualize litigants, and jotting down the passwords for your corporate bank accounts, your storage your tab probably won’t be so high. But consider lost productivity, poten- tial legal issues (and their resulting fines), compromised competitiveness Backup options and so on, and a lost laptop can easily run up a considerable bill. for ROBOs So, what are you doing about laptop backup? Our surveys and other research show that the “other” backup problem—backing up remote and Hybrid branch offices—finally seems to be under control (see our latest Snapshot clouds loom survey, “Users get upper hand over remote site backup,” page 48 in this issue). But mobile computing is still an issue, and it’s gotten a little muddled Remote backup lately with smartphones and tablets getting added to the mix of things to under control worry about. Not too long ago laptop backup might have been one of the toughest data protection nuts to crack, with few alternatives and little or no integra- Sponsor resources tion with other backup processes. Cloud backup services (and there are tons of them) now offer good alternatives, and there are a handful of new endpoint backup apps that also deserve some attention. Still, a lot of shops dismiss those alternatives as just another backup application to maintain. But if you haven’t had the time to check specs lately you might not know how much the mobile backup landscape has changed, and now the 6 STORAGE August 2011 STORAGE odds are that whatever your company is using right now to back up its data center and remote offices can also be used for laptops. For example, if you use a backup app from CA, CommVault, EMC, HP, IBM, Microsoft or Symantec, it has a laptop backup option. And even if you’re using a slightly less popular backup app, it’s also likely to have laptop support these days. So you can have a fully integrated backup system—data center, remote offices and mobile users—using a single app with one management console. Does adding laptop support to your backup application mean extra work Lax laptop backup for your overtaxed crew? Sure, and if you have a lot of laptops floating around, it could be a significant effort to protect them.

  • Fast Network Connectivity Key to Unlocking All-Flash Array Performance
    Fast Network Connectivity Key to Unlocking All-flash Array Performance The current generation of all-flash arrays offers enough performance to saturate the network connections between the arrays and application servers in the data center. In many scenarios, the key limiter to all-flash array performance is storage network bandwidth. Therefore, all-flash array vendors have been quick to adopt the latest advances in storage network connectivity. Fast Networks are Here, and Faster Networks are Coming Ethernet is now available with connection speeds up to 400 Gb per second. Fibre Channel now reaches speeds up to 128 Gb per second. As discussed during a recent SNIA presentation, the roadmaps for both technologies forecast another 2x to 4x increase in performance. While the fastest connections are generally used to create a storage network fabric among data center switches, many all- flash arrays support fast storage network connectivity. All-flash Arrays Embrace Fast Network Connectivity DCIG’s research into all-flash arrays identified thirty-seven (37) models that support 32 Gb FC, seventeen (17) that support 100 Gb Ethernet, and ten (10) that support 100 Gb InfiniBand connectivity. These include products from Dell EMC, FUJITSU Storage, Hitachi Vantara, Huawei, Kaminario, NEC Storage, NetApp, Nimbus Data, Pure Storage and Storbyte. Source: DCIG Other Drivers of Fast Network Connectivity Although all-flash storage is a key driver behind fast network connectivity, there are also several other significant drivers. Each of these has implications

By Jon Toigo hile touting “new,” flash-heavy “server-side” topologies and so-called “software-defined architec- tures” as evolutionary replacements for the “legacy” W SANs and NAS appliances that companies deployed in their previous refresh cycles, the industry continues to ignore the more fundamental drivers of storage inefficiency and cost: lack of management both of infrastructure and of data. 1 Storage Spectacular You would think from news reports that the storage industry was on its last legs. Vendor revenues from sales of everything from hard disk drives to external storage arrays, storage area networks (SANs) and network attached storage (NAS) appliances are either flat or declining ever so slightly. Seagate and Western Digital have hit a patch of dol- drums in which the trends of prior years—the doubling of drive capacities every 18 months and the halving of cost per GB every year—have frozen in their tracks. Even the redoubtable EMC, NetApp and IBM are experiencing purchasing slowdowns at customer shops that shouldn’t be happening if the capacity demand explosion that analysts say accompanies server virtualization is to be believed.
