GPFS Storage

30 Terabytes of SAS and 360 Terabytes of SATA disks with aggregate performance of more than 10 Gigabytes/S.

Each RAID subsystem is connected to two of the service nodes in order to allow configuration for fail-over redundancy as  supported in GPFS. The GPFS system is integrated with a Tivoli Storage Manager  TSM) 2 Petabyte tape archival and backup system. Policy-based Hierarchical Storage  management (HSM) facilities control automatic data migration among the SAS, SATA and  tape storage pools. In addition, GPFS  supports snapshot filesystem imaging to allow easy retrieval of accidentally deleted files.

Users can also access the filesystem from other campus systems via the CIFS fileservice and through the Web via WebDAV.

The GPFS cluster runs the CentOS build of the RedHat Enterprise Linux (RHEL) operating system, and is provisioned with the xCAT open source cluster management software. Workload  management is performed using the Moab Cluster Suite, a commercially supported system for managing queuing and scheduling systems and for user job submission.
