Disclosed is a disk array system that can be expanded effectively in scale by increasing the number of input/output channels and disk adapters and improved in such performance as the number of input/output operations per second, data transfer rate. The disk array system is provided with input/output channels to be coupled to a host computer, cache memories coupled to each of input/output channels respectively and used to store input/output data temporarily, disk drives, disk adapters coupled to the disk drives, and network switches used to couple the input/output channels to the disk adapters.
