Abstract

PURPOSE:To assure the identity of data by writing data in a disk device sharing data after purging those data to be written in the cache memories in other disk devices. CONSTITUTION:When data stored in a shared disk device 6 are rewritten, the device 6 is reserved by a reserving part 3-2. Then an address and processing value are informed to other disk devices via an address/processing value communication part 3-3. At the same time, the corresponding data if stored in a cache memory 3-1 is purged away and also data are written in the device 6. Thus the consistency is assured for those data stored in the memories 3-1 built in the devices which share the device 6.
