Storage system having decentralized cache controlling device and disk controlling device, storage control program, and method of storage control

摘要

A storage system includes a cache device that has a cache memory as a high-speed-access storage medium, a disk device that has a disk as a high-capacity storage medium, and a control device that accepts an access request from a client device and makes the cache device and the disk device execute a process corresponding to the access request. The cache device, the disk device, and the control device are decentralized on a network.
