Abstract:
Degree of freedom of a device structure is increased to equalize processor loads by separating the function of executing data read and write processing from the host interface and the disk interface. A disk array device including a disk enclosure and a disk control unit, wherein the disk control unit includes a host interface connected to a host computer which accesses the disk array device, a disk interface connected to the disk enclosure, a plurality of processors that execute data read and write processing between the host computer and the disk enclosure, and a switch which connects the host interface and the disk interface, and the plurality of processors, wherein the switch having a function of selecting a processor which executes the data read and write processing.
