Abstract

The proposed storage manager allows a good adjustment of cost/ performance to be achieved by enabling a central control unit (CCU) processor, designed for high performance, to run either with very fast storage or low cost, low performance memory. This is done by overlapping the CCU and storage operations, and by providing a priority scheme to avoid contention and to maintain high performance.
