HPSS Introduction
The High Performance Storage System (HPSS) is a modern, flexible,
performance-oriented mass storage system, designed and developed by
a consortium of government and commercial entities to manage and access
hundreds of terabytes to Petabytes of data. It is deployed
at a number of sites and centers, and has been used at NERSC for archival
storage since 1998. Users are given HPSS accounts to enable them to
save and access their data.At NERSC, the data in storage doubles almost every year. As of 2004, we have over 1 petabyte of data (31 million files) and handle between 3 and 6 TBs of I/O per day. To keep up with this constantly increasing workload, we must implement new technology as it becomes available. NERSC currently has:
- Two HPSS systems:
- archive.nersc.gov (For user files).
- hpss.nersc.gov (For system backups).
- Maximum Theoretical Capacity is 8.8 Petabytes.
- Buffer (disk) cache is 35 Terabytes.
- Theoretical throughput is 2.8 GB/sec.
Users can access NERSC's HPSS machines through a variety of clients. For example, hsi, htar, ftp, pftp, and Grid clients.
