    摘要: Storage apparatus and data management methods provide for high-speed copying of a compressed data volume. A control unit of the storage apparatus divides a pool into a plurality of chunks including a plurality of pages storing data, compresses data which is written to a logical volume by a host, and assigns one of the plurality of chunks to a compressed data logical volume which stores the compressed data. When the compressed data logical volume is copied, the control unit makes a page length of the chunk assigned to the compressed data logical volume that is a copy source equivalent to a page length of the chunk assigned to the compressed data logical volume that is the copy destination.

    摘要: For betterment, by putting a virtual storage device into a suspend mode, physical resources are turned OFF on a virtual storage device basis. Moreover, control information and volume data of the virtual storage device are stored in any external volume, for example, and the resources that have been used by the virtual storage device are deallocated. At the time of resumption of operation, using any resources not in use, the virtual storage device is restored based on the control information in storage. When a change is made to a WWN on the side of a host, the storage device receives a WWN change notification from a management server, and makes settings again to a WWN table, thereby making it accessible from the host.

    摘要: If a monitor measurement cycle is set as a long cycle, promotion in a short cycle cannot be performed; and even if the number of I/Os is very large in response to fluctuations of the number of I/Os in several minutes to several hours of normal work, pages will be promoted after waiting for several weeks. As a result, I/Os which could have normally accepted by an upper tier will be accepted by a lower tier, which results in a problem of worsening the performance efficiency. A monitoring system capable of preventing demotion due to temporary reduction of the number of I/Os for specific pages from a viewpoint of a long cycle and enabling prompt promotion in response to an increase of the number of U/Os for 3 the specific pages is realized.A load index value defined from a viewpoint of a long cycle and a load index value defined from a viewpoint of a short cycle are updated based on the number of I/Os which is counted cyclically for each storage area. Promotion and demotion are implemented based on a value(s) calculated from these load index values.

    摘要: An example of an information storage system includes physical storage drives for providing real storage areas to a pool which is tiered into tiers different in performance, and a controller. The controller monitors accesses in a first tier in the pool. The controller determines a loaded state of the first tier based on the accesses to the first tier. The controller holds management information relating loads to the first tier to relocation speeds and/or modes of moving data in data relocation between a second tier in the pool and the first tier. The controller determines at least one of a relocation speed and a mode of moving data in data relocation between the second tier and the first tier based on the determined loaded state of the first tier and the management information.

    摘要: A storage apparatus for which a hierarchical data management system is adopted is designed so that when receiving a read request for a first logical area to which a first storage area of a first storage device in a virtual volume is allocated, whether or not to migrate data in a first storage area of the first storage device, to a storage area of a second storage device is decided according to an access frequency to the first logical area in synchronization with the read request. When it is decided that the data stored in the first storage area of the first storage device should be migrated to the storage area of the second storage device, the data is migrated to a second storage area of the second storage device and the second storage area thereof is allocated to the first logical area in the virtual volume.

    摘要: In a storage system which supports a redundant disk configuration, while securing fault tolerance, a longer drive access time as well as a drop in I/O throughput are prevented when a redundant data update, generated due to a data update, is mirrored in the drive.A controller for controlling data I/O to and from the drive updates first redundant data and block data of a corresponding data stripe in the disk drive in correspondence with an update of block data of the logical volume, and the controller updates second redundant data on the basis of a predetermined number of block data which belong to the same data stripe as the updated block data with different timing from the update of the block data.

    摘要: This computer system includes a first storage system and a second storage system. The first storage system has a data transfer unit for transferring the data stored in the first volume to the second volume of the second storage system. The second storage system has a snapshot creation unit for creating a snapshot of the second volume in a third volume based on a snapshot creation command. When the snapshot creation unit receives the snapshot creation command while transferring the data from the first volume to the second volume with the data transfer unit, it delays the creation of the snapshot of the second volume in the third volume until the transfer of the data from the first volume to the second volume is complete.
