ABSTRACT:
A storage system1includes: plural protocol transformation units10that transform, to a protocol within the system, a read/write protocol of data exchanged with servers3or hard disk groups2; plural cache control units21that include cache memory units111storing data read/written with the servers3or the hard disk groups2and which include the function of controlling the cache memory units111; and an interconnection network31that connects the protocol transformation units10and the cache control units21. In this storage system1, the plural cache control units21are divided into plural control clusters70, control of the cache memory units111is independent inside the control clusters, and a system management unit60that manages, as a single system, the plural protocol transformation units10and the plural control clusters70is connected to the interconnection network30.
