    摘要: The temporary area capacity required to be secured with respect to the whole permanent area is calculated in accordance with the capacity and access frequency of a host computer data permanent area of a disk device contained in the storage system and a disk device of an external storage device that is managed by a storage virtualization function of this storage system. The nonvolatile memory is defined as the temporary area and is used to temporarily store host computer data when a data I/O from the host computer is processed. The required capacity of the temporary area is re-calculated in accordance with an event such as a configuration change in the external storage system.

    摘要: The present invention transfers replication logical volumes between and among storage control units in a storage system comprising a plurality of storage control units. To transfer replication logical volumes from a storage control unit to a storage control unit, a virtualization device sets a path to the storage control unit. The storage control unit then prepares a differential bitmap in order to receive access requests. When the preparation is completed, the virtualization device makes access requests to the storage control unit. The storage control unit then hands over the access requests to the storage control unit. Subsequently, the storage control unit performs a process so that the access requests are reflected in a disk device and performs an emergency destage of storing data in a cache memory into disk device. When the emergency destage is ended, the storage control unit connects to an external storage control unit and hands over access requests to the external storage control unit.

    摘要: A first storage system is connected to a second storage system, and an external device within the first storage system is provided to a host as a device of the second storage system. The second storage system includes a cache control section having cache adaptors, each controlling a disk and a cache, a protocol conversion section including protocol adaptors that switch requests from the host to appropriate ones of the cache adaptors, a management adaptor, and an internal network that mutually connects the cache adaptors, the protocol adaptors and the management adaptor. The first storage system being connected to any of the protocol adaptors is connected to the second storage system. The second storage system executes a processing for the external device by the cache control section, or connects to the first storage system through the protocol conversion section without the cache control section executing processing for the external device.

    摘要: The storage system includes a storage subsystem including a plurality of storage units and a storage control device coupled to a computer and the storage subsystem, the storage control device providing the host computer with a logical unit assigned to a storage unit of the storage subsystem. The storage control device receives a first access request from the computer to the logical unit and sends a second access request to the storage unit of the storage subsystem according to a relation between the storage unit of the storage subsystem and the logical unit assigned to the storage unit. Performance information relating to the second access request by the storage control device is obtained so that the storage control device determines performance relating to the logical unit assigned to the storage unit of the storage subsystem.

    摘要: Access to a plurality of logical devices is enabled regardless of the number of ports provided in a storage system and the number of logical devices that can be allocated to a single port, thereby improving the usability of the logical devices. A storage system comprises a plurality of logical devices, a target device which is the object of access from a computer, and a juke box system for allocating one of the plurality of logical devices to the target device. The juke box system changes the logical device that is allocated to the target device in accordance with a request from the computer.
