Magnetic disk archive systems have significant advantages over tape archive systems in applications requiring processing of nuclear physics data sets.  However, the infrastructure costs required to power and interconnect the required number disks is prohibitive.  This project will develop innovative disk storage subsystems utilizing the lowest cost media, low-cost high-performance host interconnections, and advanced multi-level power savings techniques.  In Phase I, an architecture that satisfies both performance and cost requirements was defined.  An analysis was performed on the possible power management techniques required for large scale disk systems.  In Phase II, a prototype system, based upon further advances in large scale disk integration, will be created to allow for a thorough assessment of the overall approach.

Commercial Applications and Other Benefits as described by the awardee:  The availability of low-cost and high capacity magnetic disk systems should provide increased performance and processing capabilities to all commercial users currently archiving data on large tape library systems.
