摘要： A data element that is identical to a part of a plurality of data elements stored in a logical storage device (LU hereinbelow) is stored in a storage area (pool hereinbelow) separate from the LU. A first PDEV (physical storage device) that stores the data element stored in the LU may be placed in a power saving state while the storage system is operating (in periods when a read command can be received), and a second PDEV which stores the data element stored in the pool is not placed in a power saving state during operation. When the storage system receives a read command which is received from the host apparatus, and if the first PDEV is in the power saving state and a data element identical to the data element which is the target of the read command is stored in the pool, the storage system reads the identical data element from the pool without canceling the power saving state of the first PDEV, and sends the read data element to the host apparatus.
摘要翻译：与存储在逻辑存储装置（以下简称LU）中的多个数据元素的一部分相同的数据元素被存储在与LU分离的存储区域（下文中为下文）中。存储系统正在运行（在接收到读取命令的时段）中存储有存储在LU中的数据元素的第一PDEV（物理存储设备）可以被放置在省电状态中，并且存储第二PDEV 存储在池中的数据元素在运行期间不会处于省电状态。当存储系统接收到从主机装置接收到的读命令，并且如果第一PDEV处于省电状态，并且与作为读命令的目标的数据元素相同的数据元素存储在池中时，存储系统从池中读取相同的数据元素而不取消第一PDEV的省电状态，并将读取的数据元素发送到主机设备。

摘要： Proposed is a storage apparatus and its control method capable of performing dynamic load balancing or performance acceleration as a whole by balancing the load to a logical volume. With this storage apparatus, the load status of the volume is measured based on the data volume and command throughput transferred between the higher-level device and the storage unit. In addition, the contents of the volume having a load exceeding the default value are copied to one or more backup volumes based on the measurement results of the load status of the volume, the volume of a copy source and the backup volume of a copy destination are associated with one virtual volume, and the virtual volume is provided to the higher-level device. Moreover, when a write request involving read processing for reading data from the virtual volume is given from the higher-level device, data is read from a default volume or the backup volume associated with the virtual volume and data from the higher-level device is written in all the volumes and backup volumes associated with the virtual volume, and, when a read request for reading data from the virtual volume is given, corresponding data is read from the volume or the backup volume other than the default volume or backup volume among the volume and the backup volume associated with the virtual volume.
