HPSS
The NCCS High Performance Storage System (HPSS) provides longer term storage for the large amounts of data created on the NCCS compute systems. The mass storage facility consists of tape and disk storage components, servers, and the HPSS software.
Each NCCS user receives an account on the HPSS automatically. Users can transfer data to the HPSS from any NCCS system using the hsi or htar utilities. Initially data transferred to the HPSS is written to disk. The system then migrates the data to tape for longer term archival.
The NCCS has 3 SL8500 tape libraries, each holding up to 10,000 cartridges. The libraries house a total of twenty-four T10K-A tape drives (500 GB cartridges, uncompressed) and thirty-six T10K-B tape drives (1 TB cartridges, uncompressed). Each drive has a bandwidth of 120 MB/s.
