The High Performance Storage System (HPSS) consists of new tape libraries with storage capacity of more than 100 petabytes at the NCAR-Wyoming Supercomputing Center (NWSC) and another 15 petabytes of storage at the Mesa Lab in Boulder.
These scalable, robotic systems comprise four StorageTek SL8500 tape libraries with a total of 34,000 cartridge slots. The NWSC system features 26 T10000C tape drives and an I/O rate of 240 MBps. File metadata are maintained in DB2, IBM's real-time database system.
Scheduled preventive maintenance periods are Tuesdays from 7 to 9 a.m. Mountain time.
For information about how to receive status updates automatically, please consult our CISL Status page.
HPSS replaced the Mass Storage System (MSS) in April 2011. Files that were stored in MSS when it was decommissioned were moved to HPSS.
