摘要： The present invention suppresses the generation of redundant I/O and improves the response to the host during data migration. When migrating data from the migration source volume to the migration destination volume, the access destination of the host is switched to the second storage device. When data requested by the host has not yet been migrated, data is read from the first storage device. When the frequency of access to the non-migrated area reaches a prescribed value, the target IP address is changed and discovery is implemented so as to switch the access destination of the host to the first storage device. When the frequency of access to the migrated area in the first storage device reaches a prescribed value, the access destination of the host is switched to the second storage device. The access destination of the host is controlled based on the data migration state and access state, and the generation of redundant I/O can be suppressed.
摘要翻译：本发明抑制了冗余I / O的产生，并且在数据迁移期间改善了对主机的响应。将数据从迁移源卷迁移到迁移目标卷时，主机的访问目标将切换到第二个存储设备。当主机请求的数据尚未迁移时，从第一个存储设备读取数据。当访问非迁移区域的频率达到规定值时，改变目标IP地址并实现发现，以将主机的接入目的地切换到第一存储设备。当第一存储装置中的迁移区域的访问频率达到规定值时，主机的访问目的地切换到第二存储装置。基于数据迁移状态和访问状态来控制主机的访问目的地，并且可以抑制冗余I / O的产生。

摘要： A controller unit, a plurality of storage devices, a log area, and a normal area are provided. A quantity of log storage devices forming the log area is smaller than a quantity of normal storage devices forming the normal area. In an operational period, in which the controller unit may accept an input-output command, a power consumption condition of the log storage devices is constantly in a normal condition in which an input or output of data can be carried out, while a power consumption condition of the normal storage devices is in an energy saving condition in which a power consumption is lower than in the normal condition. The controller unit, when receiving the input-output command if the power consumption condition of the normal storage devices is the normal condition, carries out an input or output with respect to both the normal area and the log area.

摘要： Snapshots are implemented by combining original data in a place where an operational volume has been updated with data in a place where the operational volume has not been updated. A snapshot management table maintains a value indicating that update has not been conducted, or a storage place of original data, for each of combinations of blocks in the operational volume and the snapshots. If there is a snapshot in which update has not been conducted in a update place at the time of update, then original data is copied and the snapshot management table is updated. The copied original data is managed by a difference block management table, which has a value indicating whether respective snapshots are referencing the data. If a snapshot is deleted, then the value indicating that the snapshot is referencing is altered in all entries in the difference block management table.
