A storage system 1 includes: plural protocol transformation units 10 that transform, to a protocol within the system, a read/write protocol of data exchanged with servers 3 or hard disk groups 2 ; plural cache control units 21 that include cache memory units 111 storing data read/written with the servers 3 or the hard disk groups 2 and which include the function of controlling the cache memory units 111 ; and an interconnection network 31 that connects the protocol transformation units 10 and the cache control units 21 . In this storage system 1 , the plural cache control units 21 are divided into plural control clusters 70 , control of the cache memory units 111 is independent inside the control clusters, and a system management unit 60 that manages, as a single system, the plural protocol transformation units 10 and the plural control clusters 70 is connected to the interconnection network 30.
