HPSS (High Performance Storage System) is a storage management system especially designed for moving large files and large amounts of data around a nework that may consist of parallel processing computers, supercomputers, and clusters of high-end workstations. HPSS is especially valuable for moving around large amounts of data for scientific and other complex applications and for moving large video files across the network.
Geared to work with both directly-connected and network-attached storage devices, HPSS supports data transfer rates greater than 1 gigabytes per second and is aimed at enterprises that handle quantities of data in the petabyte range. The HPSS technology makes use of "data movers," which are specialized software modules geared to sending very large data streams.
A joint development of industry and the U.S. government, HPSS is the result of contributions from more than 20 organizations, including Transarc, Objectivity, IBM, Los Alamos National Laboratory, and the San Diego Supercomputer Center. HPSS vendors include Cray, SGI, Sun Microsystems, and Intel.
