“The second generation of SDSC’s Data Oasis Lustre storage is coming online to support Comet, a new XSEDE cluster targeted at the long tail of science. The servers have been designed with Lustre on ZFS in mind, and also update the network to use bonded 40GbE interfaces. The raw storage totals 7.7 PB and are again based on commodity hardware provided by Aeon Computing, maintaining our focus on cost.”
