ABSTRACT:
Under a hetero-environment in which different sorts of disk-systems are mixed with each other, a data guaranteeing operation can be carried out. When a cache controller of a local disk system receives a data writing request from a host computer the cache controller stores data into a local disk provided in a disk device group. The data received from the host computer is also transmitted to a remote disk system, and is stored in a remote disk. The data stored in the remote disk is immediately read and the data written in the remote disk is compared with the data written in the local disk. As a result, since a data guarantee operation on the remote side is processed by the local disk system instead of the remote disk system, a data guaranteeing operation when a remote copying operation is performed can be carried out even in the storage system under a hetero-environment.
