Abstract
A storage apparatus comprises a storage controller and multiple storage devices. The storage controller sends, to either a storage device which is a copy source of copy-target data, or a storage device which is a copy destination of the copy-target data, a copy indication showing areas of the copy source and the copy destination, and the storage device, which receives the copy indication, copies data of the copy-source area to the copy-destination area based on the copy indication without going through the storage controller.
