Ibrix's Fusion FileMigrator feature, new to its Fusion 4.2 clustered file system software, supports any type of storage within the Ibrix namespace. Ibrix president Milan Shetti said that Fusion customers consist mainly of high-performance computing (HPC) shops using a SAN and Web 2.0 service providers who prefer direct attached storage (DAS). But that's changing as data grows in both types of environments, and customers seek ways to archive files.
"They want to use DAS to migrate files from a movie project that's finished, for example," Shetti said. "Or they want some of their files on solid-state drives for faster processing."
Other clustered NAS products, such as Isilon's IQ storage nodes, can migrate data according to policy between different classes of disk. But Isilon's storage requires Isilon hardware; Ibrix's software can run on any type of block storage. However, the Ibrix version only supports devices that are part of a global namespace, making migration to offsite media, such as tape, impossible
The FileMigrator feature "addresses a huge pain point," said Terri McClure, an analyst with Enterprise Strategy Group. "No manual migration between storage tiers with all the associated remapping of mount points, no managing Tier 1 in a separate instance from Tier 2 and Tier 3 – it's all managed in the same pane of glass. That's a big ease-of-use and storage optimization play and should appeal to users."
Forrester analyst Andrew Reichman points out that Fusion already had this capability, and Shetti confirmed that customers could migrate files in earlier versions but needed to use scripts. "It's more like a repackage of some existing capabilities, but it's a great idea that solves a real business problem," he said. "It's not a vague ILM thing."
