HPSS at NCARThe High Performance Storage System (HPSS) consists of robotic tape libraries with storage capacity of more than 320 petabytes at the NCAR-Wyoming Supercomputing Center (NWSC) and another 15 petabytes of disaster-recovery data storage at the NCAR Mesa Lab in Boulder.

These scalable 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.
