摘要：
A control method which is used in a RAID1 storage subsystem including a plurality of storage devices, and processes an access request from a host computer with the cooperation of the plurality of storage devices of the storage subsystem is provided. In the storage subsystem, each storage device of the RAID1 storage subsystem includes a unit for sharing an access request from the host computer, and a unit for determining if the storage device should process the shared access request. The storage device further includes a unit for transferring write data, which is transmitted from the host computer to the storage subsystem, to at least a storage device that should process it.
