Abstract
Large numbers of relatively small (e.g., 1.8" or smaller) off-the-shelf disk drives are controlled to maximize the highest throughput performance at the least cost between a host computer and a mass storage subsystem. Host data is stored redundantly so as to form a cache. The controller recognizes data contained in its associated disk cache so as to produce that data to a requesting host with minimum delay. Data not in the disk cache as well as write commands are transferred to the controller of a mass storage subsystem with no substantial delay.
