摘要： A virtual storage system is equipped with a plurality of storage systems and a virtualization device for virtualizing the plurality of storage systems logically into a single storage resource provided to a host computer. When one of the storage systems receives a command from the host computer, in the event that the storage system itself is not in possession of a function corresponding to the command, the storage system retrieves a storage system in possession of a function corresponding to the command and transfers this command to the storage system in possession of the function corresponding to the command.

摘要： The present invention allocates a suitable physical device to each volume page according to the state transition command relating to paired volumes. A plurality of logical devices forming a logical storage area of a plurality of physical devices of varying performance are tiered according to the performance of the physical devices to form a pool volume, and each of the areas of the primary logical volume, secondary logical volume and pool volume are managed by a controller, divided into a primary page, secondary page and pool page. Upon receiving a pair formation-related command from the host computer, the controller allocates pool pages belonging to the same tier to the primary page and secondary page, and upon subsequently receiving a pair-related state transition command, the controller allocates a pool page, in a different tier from the primary page, to the secondary page.

摘要： Provided are a computer system and its data control method that enable safe backup of data and reduction in the capacity of data to be backed up. A control processor refers to a differential and, if a differential bit is “0,” encrypts data of an online VOL with an encryption circuit by using key information, and transfers the encrypted data to a second storage system. If the differential bit is “1,” the control processor performs redundancy elimination processing to journal data, thereafter compresses the journal data with a compression circuit, encrypts the compressed journal data with an encryption circuit according to the key information, and transfers the journal data that was encrypted after compression to the second storage system.

摘要： When a computer 10 receives a request from the client computer 30 to access snapshot files, the target device to be used is identified. The computer 10 makes a request to the identified target device TD for attachment of the logical device LDEV that stores the snapshot files for which access is requested. When the computer 10 receives notification that the attachment has ended from the storage device system 20, the identified target device is mounted on the directory in which the snapshot files are stored.
