Cluster File Systems (CFS) this week released the latest update to the open source Lustre file system. Lustre version 1.4.5, available to CFS customers since August 2005, is now available to the general public at no cost. Furthermore, CFS has substantially accelerated its release policy to advance the adoption of Lustre in the free software community. While Lustre has always been available to customers under an open source license, CFS announces that future versions will be released to customers and the general public simultaneously. Community users will no longer need to wait for access to the newest open source Lustre software. "CFS is profitable, we're growing, and we're absolutely committed to open source," wrote Phil Schwan, CEO of Cluster File Systems, in an email to users. "This announcement further demonstrates our desire to provide quality advanced software to the free software community."
