IBM updates San File System software

IBM in June will release a new version of its TotalStorage storage area network (San) File System software designed to work with a wider variety of new server and storage environments.

Unlike previous versions of the San File System, which supported only IBM products, version 2.1 will work with storage devices from IBM rivals including EMC, Hewlett-Packard, and Hitachi Data Systems. It will also now support the Red Hat Linux Enterprise Server 3.0 and Sun Microsystems' Solaris 9 operating systems.

The software, which will begin shipping on 29 June, has also been enhanced to allow customers to move data from one device to another without disrupting their server operating systems, said Jeff Barnett, manager of IBM's storage software strategy. "The environment itself is designed so that it isolates your server environment from your storage environment," he said.

IBM's San File System is based on Sanergy technology the company acquired from Mercury Computer Systems in 1999, and while it was initially released as a product last autumn, it has been under development for some time, said Arun Taneja, founder of storage industry research firm Taneja Group.  "IBM's San File System is fairly mature in that regard, because it didn't start from scratch," he said.

San file systems are useful for companies looking to provide a number of different servers with identical views of data on the network, Taneja said. "This kind of stuff comes into play where there are large amounts of data, you have heterogeneous server environments, and you have the need for several servers to work with each other on a particular application."
