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： A storage system connected to a computer and a management computer, includes storage devices accessed by the computer, and a control unit for controlling the storage devices. A first-type logical device corresponding to a storage area set in at least one of the storage devices and a second-type logical device that is a virtual storage area are provided. The control unit sets at least two of the first-type logical devices different in a characteristic as storage areas included in a storage pool through mapping. The first-type logical device stores data by allocating a storage area of the second-type logical device to a storage area of the first-type logical device mapped to the storage pool. The characteristic of the second-type logical device can be changed by changing the allocated storage area of the second-type logical device to a storage area of another first-type logical device.

摘要： The data up to a point of time whereat failure has occurred will be restored at high speed at a remote site without imposing any burden on a host. The first storage system on the master side processes an I/O request from the host, and as a result of I/O processing to the second storage system on the remote side, transmits the update data. The second storage system retains data received from the first storage system as update log data. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. The host and the second storage system both retain an identifier corresponding to the command, and relate the identifier to the log data. Thereby, the host designates the identifier at any given time, whereby the second storage system restores the data at any given time.
摘要翻译：直到发生故障的时间点的数据将在远程站点高速恢复，而不会对主机造成任何负担。主机侧的第一存储系统处理来自主机的I / O请求，并且作为对远程侧的第二存储系统的I / O处理的结果，发送更新数据。第二存储系统将从第一存储系统接收的数据保留为更新日志数据。主机向第一存储系统发送用于确定应用状态的命令作为数据，并且第一存储系统将数据发送到第二存储系统。主机和第二存储系统都保留与该命令对应的标识符，并将该标识符与日志数据相关联。因此，主机在任何给定时间指定标识符，由此第二存储系统在任何给定时间恢复数据。

摘要： The present invention controls supply of power to a storage device on the basis of an access status, moves a logical storage device between physical storage devices having different power supply modes, reduces energization time, and improves the reliability. A relocation plan creation portion creates a relocation plan by disposing a logical volume with high access frequency in a RAID group which is in a long-time energization mode, disposing a logical volume with moderate access frequency in a RAID group which is in a first short-time energization mode, and disposing a logical volume with low access frequency in a RAID group which is in a second short-time energization mode. An execution time determination portion determines an execution time for executing the relocation plan, on the basis of the access frequency to the RAID groups. The volumes with higher access frequency are disposed in the RAID group in which the power supply time is long, and the volumes with lower access frequency are disposed in the RAID group in which the power is supplied in an on-demand fashion.

摘要： A recovery method that uses log takes a long time to recover, and another recovery method that uses backup has the difficulties that if a computer abnormally stops its conversion process due to a failure, the result of the conversion performed up to the time of that abnormal stop couldn't be reflected on the later process for recovery. In a computer system, a system recovery management unit produces backup as the initial status of volume and snapshot taken when the system is operating, by use of a backup restore processing unit of a storage apparatus, and manages the situations of the process by use of a recovery point list/table. When a trouble occurs, it determines a point of recovery from the recovery point list/table, and makes the volume be recovered from the produced backup and the overwriting of meta data in order to keep the data consistency.

摘要： In a storage subsystem, performance tuning is performed with respect to all of the logical devices including external storage subsystems that are not directly connected to host computers. The physical storage units presented by the external storage subsystems are defined as logical devices of the storage subsystem, and I/O processing requests from the host computers are relayed to the logical devices. At the time of relaying, I/O processing conditions are monitored. When the load of an external storage subsystem is high, then operating conditions of ports and processors are examined. When the load can be reduced by changing the configuration of those ports and processors, the configuration is changed to reduce the load. When the load can not be reduced, data is migrated from a logical device having a high load to a logical device having a sufficient performance.
