摘要： Provided is a computer system including a first storage subsystem and a second storage subsystem. The first storage subsystem has a first storage unit and a first control unit. The second storage subsystem has a second storage unit and a second control unit. The first control unit records journals, and identifies, when data stored in the first storage unit is to be migrated to the second storage unit, which ones of the recorded journals are related to the data that is to be migrated. The first control unit chooses the identified journals one at a time in reverse chronological order, and judges whether or not the chosen journal corresponds to a data update made at some point between a current time and a time that precedes the current time by a length of a journal retention term set for the second storage subsystem.

摘要： A first storage system includes a first storage area for storing data written by a computer. A second storage system includes a second storage area to which the data stored in the first storage area migrates. A third storage system includes a virtual storage area corresponding to the second storage area. An access request to the virtual storage area is converted into an access request to the second storage area to be issued. A management computer transmits, to the third storage system, an instruction to migrate the data of the second storage area to a third storage area of the third storage system based on a determination result between a value of the data migrated to the second storage area and a predetermined threshold value.

摘要： A storage system has a pool which is made up of a plurality of storage regions supplied by physical disks, and allocates the storage regions within this pool to volumes supplied to host computers, and cancels such allocations. When a volume addition event has occurred, a management computer forecasts, for each volume, the capacity which is to be required at a certain time point in the future, based on usage capacities acquired for each volume, calculates a non-required capacity from this capacity which has been forecast and the capacities of the storage region groups which are already allocated to the volume, decides, based on one or more non-required capacities which have been calculated, whether or not there is a storage region enough to satisfy the capacity requested for a volume which is the object of addition, and, if a positive decision result is obtained, allocates storage regions equivalent to the non-required capacity to the volume which is the object of addition.

摘要： A caching storage method and system that includes one or more host devices, network devices, storage devices, and logical volume management functions. An input/output (I/O) request is received from the host device that includes a logical block address. The logical block address is translated into an original storage address for a storage device that includes an original storage ID, storage unit ID and block address. It is determined if a cache is defined for the storage device. The original storage address is translated into an address for a cache associated with the storage device if the cache is defined for the storage device. A read request or a write request is sent to the cache address based on the I/O request. Block data is received or transferred from/to the cache defined for the storage device identified by the original storage ID and storage unit ID.

摘要： At the time of migrating encrypted data into another storage apparatus, it is made easy to decrypt this data after migration, the security against tapping, falsification and the like is maintained when a calculation method of encrypted data is re-written into another calculation method, and also access performance is improved. In a storage system 100 which is provided with a storage apparatus having a volume 120 and which is accessible from a host computer, it is made possible to execute the data migration when a storage apparatus provided with a mechanism capable of decrypting the encrypted data is chosen as a migration destination of this data, and also to keep holding surely the encrypted data by updating and saving again a encryption method applied to a encryption of the encrypted data into another method by internal processing of the apparatus even when the apparatus and the encryption method become obsolete.
