摘要：The copy of data in two directions is realized without fixing a copy direction toone direction between storage device systems which constitute a copy pair. In storagedevice systems which constitute a copy pair, a data consistency holding control part is

disposed. The data consistency holding control part operates so as to write write-in datato a logical volume which forms the copy pair into a physical storage device after cachepart has waited for more than a predetermined time from the corresponding receptiontime, in such a manner that, when write-in data which was received from a superior deviceand write-in data which was received from another storage device system through DKCI/Fare written into the same storage location of the physical storage device in an

overlapped manner, they are written in the order of the time of reception on which thewrite-in data was received from a superior device.
