ABSTRACT:
A storage system is provided which is capable of realizing a remote copy function for speeding up lines virtually by satisfying such demand to distribute copy data into a plurality of lines. In a storage system for connecting a local storage device and a remote storage device via a plurality of lines, the local storage device includes a remote copy program for distributing data of a plurality of logical volumes accessed from a host computer into a plurality of paths on the basis of status of the plurality of paths interposing the plurality of lines, to perform a remote copy from the local storage device to the remote storage device. Accordingly, the local storage device distributes data of the logical volumes into the plurality of lines to copy the data to the remote storage device, resulting in speeding up the lines virtually.
