The High Performance Storage System (HPSS) is available on all OCF (CZ/RZ) and SCF production systems. Each user has a storage account with passwordless access from LC systems.

LC has archival storage systems for moving files between LC file systems and HPSS archival storage on all three networks: CZ, RZ, and SCF.

HTAR ("HPSS Tape Archiver") is an LC-designed TAR-like utility program that makes TAR-compatible archive (library) files but with High Performance Storage System (HPSS) support and enhanced archive-management features.
