<p>The purpose of the present invention is to improve disk access performance regardless of arrangement of a copy destination disk and a copy source disk. An information processing apparatus (1) is a control apparatus performing access control and copy control of a disk unit (6), and forms a storage apparatus together with the disk unit (6). A copy controller (3) manages copy sessions (9) each of which is a unit of management of copying a copy source data area on a copy source disk to a copy destination data area on a copy destination disk. When there is a plurality of copy sessions (9) using the disk unit (6) as a copy destination disk, a copy session management unit (4) performs scheduling of the copy sessions (9), and notifies the copy controller (3) controlling the copy source disk of the schedule. An execution unit (5) which has been notified of the schedule executes a copy of a copy session (9) according to the schedule.
