High Performance Storage System (HPSS) is the result of over two decades of collaboration among five Department of Energy laboratories and IBM, with significant contributions by universities and other laboratories worldwide.
HPSS can manage petabytes of data on disk and robotic tape libraries, providing highly flexible and scalable hierarchical storage management that keeps recently used data on disk and less recently used data on tape. Through the use of cluster, LAN and/or SAN technology, HPSS aggregates the capacity and performance of many computers, disks, and tape drives into a single virtual archival system of exceptional size and versatility. This approach enables HPSS to easily meet otherwise unachievable demands of total storage capacity, file sizes, data rates, and number of objects stored.
Technology Integration members develop and maintain components of HPSS responsible for the administrative interfaces, low level data management, and logging.
