Abstract: A virtual tape device includes a storage unit, a cache determining unit, a selector, and a cache controller. The storage unit records logical volume information associated with an identifier of a logical volume, an updated time of the logical volume, information indicating whether the logical volume is allocated to a cache, an identifier of a physical volume storing data of the logical volume, and information indicating whether the physical volume are mounted in a physical tape drive. The cache determining unit determines, based on the logical volume information, whether the logical volume exists on the cache, when a request to store the logical volume on the cache is received and the cache does not have an available capacity. The selector selects the logical volume based on the determined result as an off-cache target logical volume. The selected logical volume is off-cached by the cache controller.

The relay device transfers, if the channel is not in operation, the access request sent to the first virtual area section, to another relay device via the communication channel connected to the port.
