ABSTRACT:
A diskarray system includes a disk device for storing write data received from a computer, a cache memory, and a controller for controlling input and output of data to and from the disk device. The controller determines whether or not the write data is already written in a storage area of the diskarray system to be written specified by a write command received from the computer. When the write data for the storage area to be written is not written yet in the diskarray system, the controller receives the write data according to the write command and stores the received data in the cache memory.
