SSCL-PDSF Data Management System

Physics and detector simulations at the Superconducting Super Collider Laboratory (SSCL) are performed on a heterogeneous network of RISC based workstations named the Physics and Detector Simulation Facility (PDSF). These simulations can be characterized by the consumption and generation of large amounts of data. It is clear that on-line disk storage must be supplemented by off-line tape storage. For the PDSF, an 8-mm tape robot system was initially chosen in order to provide tertiary data storage based on its compactness and low cost. In order to manage this data, the Physics Computing Department designed the Data Management System (DMS)
