Whamcloud announced the release of Lustre 2.2. This release is the first Whamcloud release partially funded by financial support from OpenSFS -- the North American Lustre community group. Features include performance, recovery and parallelization improvements.

"Collaboration around Lustre development has never been better. The collaborative community support model led by the open source file system community with important leadership and contributions by Whamcloud has enabled Lustre to not only meet end user requirements but also follow a strict roadmap schedule.

Whamcloud is thankful for OpenSFS's financial role in getting us here," said Peter Jones, Lustre Support and Releases Manager at Whamcloud. "I'd like to send out congratulations to my team at Whamcloud and to the wider community of Lustre contributors on Lustre 2.2."
