Other than the availability of bigger boxes (or clear, plastic ones) it's hard to point to big changes in the way we store our stuff. Shifts in data storage are similarly mundane. But like the physical storage industry, which has seen few innovations in recent years, business-class data storage is quietly making its own incremental improvements—with support from venture capitalists.
Enterprise storage companies raked in $237.7 million in venture capital during the first half of this year, up from $145.9 million during the same period the year before, according to data from the National Venture Capital Assn. That's the highest level since the first half of 2002.
Three trends are making storage startups, well, if not sexy, then at least a focus for IT managers: virtualization, the incredible increase in data, and the opportunities offered by cloud computing. Paul Gottsegen, a vice-president of marketing for Hewlett-Packard's enterprise server and systems group, told me that companies building out large-scale computing systems to deliver software as a service, and even computing clouds, are far more interested in better storage features than tweaks for servers. And they're willing to pay extra for them. That focus on storage is one of the reasons HP said on Wednesday that it had agreed to spend $360 million to buy LeftHand Networks, whose software can be used to create virtualized storage clouds on an Ethernet network.
Quick Access to Data
We're not talking about online backup services, which include players such as Carbonite or Moxy, but rather software and systems that offer businesses a way to filter and keep data in a place that makes it easily accessible. Backup is only a small aspect of the storage equation, where the real solution is managing the onslaught of data. IBM, which in September launched 30 new storage products, estimates the amount of data saved for the average business user will rise to more than 16 terabytes by 2020 from just one terabyte today.
Companies want to store this data more compactly, get to it faster, and provision it quickly. To reduce the amount of redundant data stored, the big vendors have pushed a technology called deduplication, which intelligently scans the data to be kept and only stores changed files. Pushing that idea further are venture-backed startups Ocarina Networks, which has raised an undisclosed amount of money from Kleiner, Perkins & Highland Capital Partners, and Storwiz, which received $19 million in April from Sequoia Capital and Bessemer Venture Partners. Both offer a way to further compress each individual file by using proprietary algorithms.
Getting to the data faster means adding more disks, speeding up processing power, or upgrading to faster networks. There are some startups peddling appliances that can help. Gear6 and Atrato both claim to work with existing equipment to cache data that's likely to be needed so it can be accessed quickly. Atrato raised $18 million in February from Aweida Venture Partners, and Gear6 raised $10 million in March from Horizon Ventures, U.S. Venture Partners, and InterWest Partners.
Rapid provisioning—and making it easy to tie storage to a cloud of virtualized servers—has been a focus for some time now; LeftHand Networks and EqualLogic, which was acquired by Dell last year for $1.4 billion, both offer tools for those tasks. Most startups are steering clear of direct competition with the large disk-drive filled storage boxes, sold by the likes of HP, IBM, EMC, and NetApp, and are instead trying to focus on markets or areas of the data center where the big guys don't play or where they can add more value.
A Move Toward Cloud Storage
Others are taking to the clouds. Greg Gretsch, a managing director at Sigma Partners, says he's interested in the idea of cloud storage offerings for small businesses delivered through a managed service provider. To that end, he's backing Zetta, a startup trying that model that's still in stealth mode. Gretsch also funded EqualLogic; Zetta, he says, draws on the experience of EqualLogic founders to sell into the small- and medium-sized business space.
"Virtualization and the amount of data has been the biggest thing in the last 18 to 24 months for storage, but the next thing is a move toward cloud storage," says Gretsch. "Cloud computing will require cloud storage, and [Amazon's] S3 has some limits to it."
Last year other VCs backed a direct competitor to S3, Nirvanix, another cloud storage service sold to programmers, with $12 million in funding. An enticingly named startup called CloudSwitch also appears to targeting cloud storage and is backed by Matrix Partners. So while data storage may be the computing equivalent of a garage, sometimes that's the place where great companies are built.
