In the application example shown in FIG. 1, the access control interface 3 is, for example, coupled to three servers and three array hard disk devices (Redundant Array). Between the Independent Disks (RAID); however, the number of servers and arrayed hard disk devices that can be coupled is not limited. In addition, the access control interface is used.
