"The Cray Advanced Storage Architecture (CASA) defines three levels of storage available to a Cray supercomputer:"

"Level 1 is scratch storage that is dedicated to the HPC system and is directly accessible from all compute nodes.
... Cray has a strong relationship with Cluster File Systems (CFS) and several years experience deploying Lustre on its largest HPC systems."

"Level 2 is site-wide storage that is external to the HPC system and is accessible by all platforms on the external network.
... At this level, Cray will use NFS as an interface to enterprise-class, clustered NAS (network-attached storage) controllers from vendors such as Blue Arc."

"Level 3 is deep archive storage that is part of a system-wide HSM (hierarchical storage management) or archival system.
... In addition to traditional tape, Cray will use MAID (massive arrays of idle disks) to provide high-density, high-speed back-up to its Level 1 and Level 2 storage solutions."

"San Diego Supercomputer Center (SDSC), also a current COPAN customer, provided independent power consumption testing of COPAN’s Enhanced MAID.
... The findings confirm that the very low power requirements of the Cool Bytes Enhanced MAID architecture combined with the extremely dense storage capacity delivers an impressive 91 terabytes (TB) of capacity per kilowatt (KW) consumed, the highest density in the industry. This compares to an average power density for Fibre Channel disk products of approximately 4TB per kilowatt and an average rate for standard SATA disk products of 17TB per kilowatt."
