An access data string transmitted from a host (10) is sent to a center module (CM) via a channel adapter (CA). Here, it is set whether to perform striping management. When the striping management is performed and data is divided into stripes, each of the stripes divided is sent to device adapters (DA). In the device adapters (DA), it is possible to set what kind of control is to be performed for RAID (5) and whether to perform mirroring or perform nothing. When control of RAID (5) is performed, a parity is added to the data divided into stripes and the data is stored in a physical disc connected to the device adapters (DA).
