摘要： A storage system is provided with a plurality of physical storage devices, a cache memory, a control device that is coupled to the plurality of physical storage devices and the cache memory, and a buffer part. The buffer part is a storage region that is formed by using at least a part of a storage region of the plurality of physical storage devices and that is configured to temporarily store at least one target data element that is to be transmitted to a predetermined target. The control device stores a target data element into a cache region that has been allocated to a buffer region (that is a part of the cache memory and that is a storage region of a write destination of the target data element for the buffer part). The control device transmits the target data element from the cache memory. In the case in which a new target data element is generated, the control device executes a control in such a manner that the new target data element has a high tendency to be stored for a buffer region in which the transmitted target data element has been stored and to which a cache region has been allocated.

摘要： A plurality of global LDEV managed by a plurality of controller modules are provided above local LDEV under the control of each controller module. Each global LDEV is correlated to any of the plurality of local LDEV. The controller modules judge whether or not a local LDEV correlated to a global LDEV specified by an I/O request received from a host device or a first other controller module is a management target itself, and if the result of that judgment is affirmative, the controller modules access the local LDEV correlated to the specified global LDEV, while if the result of the judgment is negative, the controller modules transfer the received I/O request to a second other controller module.

摘要： A first storage system comprises an information processing device and a first volume, and is connected to an information processing device. A second storage system comprises a second volume and is connected to the first storage system. The second storage system performs power supply control relating to the second volume in cooperation with a remote copy, such that the remote copy and the power supply control are performed efficiently. Thus, a remote copy function performs power supply control of an HDD comprising a secondary volume of a remote copy pair, to match data copy status (such as stopping data copy to the secondary volume, or differential copying). Thus, longevity of the HOD and lower use of active power of a storage system can be realized.
