Abstract
To provide a storage system which enables usage of a greater volume of cache than that of a cache memory provided to a disk array control unit, including a first disk array control unit, a second disk array control unit, a plurality of disks, and a disk array control unit communication path between a first data transfer control unit and a second data transfer control unit, wherein the first data transfer control unit selectively sets either a first path through a first host input/output control unit, the first data transfer control unit, and a first disk input/output control unit, or a second path through the first host input/output control unit, the first data transfer control unit, the disk array control unit communication path, the second data transfer control unit, and a second disk input/output control unit, and then processes a data input/output request from a host.
