摘要： In a computer system that includes plural host computers and plural data storage apparatuses (storage systems) and performs, in particular, virtualization of a data storage area, unless zoning is performed correctly to activate a zone between a data storage apparatus holding a virtualized data storage area and a device holding a data storage area storing actual data, the storage area storing actual data cannot be used from the host computers. The present invention provides a mechanism for grasping a relation between the virtualized data storage area and the data storage area storing actual data, configuring a zone between data storage apparatuses holding the data storage areas as a special zone, and always activating the special zone at the time of zoning configuration. The invention further provides a mechanism for grasping a relation between the virtualized data storage area and the data storage area storing actual data, associating a zone for connecting the host computers and a first-tier data storage apparatus and a zone for connecting the first-tier data storage apparatus and a second-tier data storage apparatus, and activating a second zone according to switching activating first zone.

摘要： There is provided a logical volume management method for storage system. When a logical volume is created on a flash memory drive, a management computer allocates logical volume while flash memory chip border of flash memory drive is taken into account. Specifically, a table for managing a correlation between each parity group and the flash memory chip of the flash memory drive is obtained and the logical volume is allocated in such a manner that a flash memory chip is not shared by a plurality of logical volumes. When complete erasing of logical volume data is performed, the management computer specifies a flash memory chip on which complete data erasing is to be performed, and the storage system completely erases data exclusively on the chip of interest with a use of a function of completely erasing data at a time by chip unit of the flash memory chip (chip erasing).

摘要： At the time of migrating encrypted data into another storage apparatus, decrypt this data after migration is simplified, and 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 an 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.

摘要： A storage system includes physical memory devices, pool volumes, including real areas, an allocation-on-use (AOU) volume including virtual areas, and a controller allocating a non-allocated real area in a pool including the pool volumes to a virtual area corresponding to an address specified by a writing command when no real area is allocated to the virtual area, and writing data corresponding to the received writing command to the allocated real area. The controller moves data stored in all the real areas in a first pool volume allocated to the AOU volume to a second pool volume, and changes a power consuming status of the physical memory device constituting the first pool volume to a power saving mode after the data has been moved.

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.
