摘要： The storage system of the present invention is able to generate one virtual logical device from different logical devices which exist in each of the different storage control units and remote-copy all or part of the virtual logical device to another logical device. The same virtual identifier is set for a volume of the first storage unit and for a volume of the second storage unit. The path control unit of the host identifies a plurality of volumes which have the same virtual identifier as one virtual volume. A remote copy pair can also be set by a virtual volume and a volume of the third storage unit. The setting of the virtual volume and the setting of the remote copy can be performed by means of an instruction from the management server.

摘要： Proposed is a storage system capable of preventing the compression of a cache memory caused by data remaining in a cache memory of a storage subsystem without being transferred to a storage area of an external storage, and maintaining favorable I/O processing performance of the storage subsystem. In this storage system where an external storage is connected to the storage subsystem and the storage subsystem provides a storage area of the external storage as its own storage area, provided is a volume for saving dirty data remaining in a cache memory of the storage subsystem without being transferred to the external volume. The storage system recognizes the compression of the cache memory, and eliminates the overload of the cache memory by saving dirty data in a save volume.

摘要： A storage device system in which migration of data from an existing storage device to a higher-standard storage device is unnecessary, and in which discarding of existing storage devices by the user can be prevented. A CHF 61 receives a Read Capacity command from a new-type storage device 25 (S101). Using LDEV, LUN and other information tables, an LUN 87 is converted into a mapped LDEV (S102). A check is performed to determine whether the LDEV emulation type is read-only, write-only, or read/write (S103). If none of these, a check is performed to determine whether the emulation type is newly created (S104). If newly created, the size of all storage areas of the LDEV are set as the Max LBA in a response to the new-type storage device 25 (S105). If the result of S103 is YES, the size of the user area in the LDEV is set as the Max LBA in a response to the new-type storage device 25 (S106). If not newly created, processing proceeds to the processing of S106.

摘要： A storage system or data management and migration method enabling migration of an access destination for a host system without having to stop the transmission of data between the host system and storage apparatuses. The storage system includes: a host system that issues a data read/write request; an external storage apparatus that provides an external logical volume for storing the data; and a first storage apparatus that creates a first virtual logical volume. In this system, the host system makes a request to the first storage apparatus to map volume information composed of the management information for the external logical volume; in response to the mapping request, the first storage apparatus maps the volume information for the external logical volume onto the first virtual logical volume and sends the volume information for the external logical volume and first virtual logical volume to the host system; based on the volume information for the external logical volume sent from the first storage apparatus, the host system searches for any virtual logical volume having the same volume information as the volume information for the first virtual logical volume or external logical volume, and sets the virtual logical volume searched for in this search as an alternate volume for receiving requests to read/write data from/to the external logical volume.

摘要： A storage apparatus is capable of relocating volumes accurately even when a plurality of storage apparatuses are connected. The storage apparatus comprises an external connection function for recognizing an external logical volume set on a physical storage device as a logical volume inside the storage apparatus, a storage control device with a volume relocation function for relocating the logical volumes based on set conditions, and a storage unit with a plurality of physical storage devices. When the host sends a read request to the logical volume set on the physical storage device of the storage unit, the volume relocation function generates internally the same read request to the external storage volume set on the physical storage device in the external storage apparatus and relocates volumes based on the monitor information obtained by monitoring responses to the read request.

摘要： A storage controller of the present invention writes data to a storage device, in which the storage unit is fixed, at a size that is larger than this storage unit, and curbs response performance degradation. A host sends write-data in a prescribed number of logical blocks in accordance with a basic I/O size defined at initialization. A controller respectively creates a guarantee code for each logical block, and appends same to the write-data. Write-data, to which a guarantee code has been appended, is stored in another prescribed number of logical blocks in accordance with a basic disk access size which is set at a value corresponding to the basic I/O size, and sent to a storage device. When an unused part is also stored in the storage device, the utilization efficiency of the storage area decreases, but the need to read out data located before and after data targeted for updating at data write is eliminated, thereby curbing the degradation of response performance.

摘要： A storage control system is provided where a first host system connected to a first storage controller can issue a control command to a second storage controller connected another host system. The first storage controller is connected to the second storage controller and the command is issued without providing the command to the other host system. The first storage controller has a virtual volume, a memory unit for storing information necessary for mapping the virtual volume to a logical device in the second storage controller, and attribute information for the logical device. The host system identifies the virtual volume as the logical device in the second storage controller and issues a control command to this logical device via the virtual volume.
