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. 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.
