Abstract: A storage system includes physical memory devices, pool volumes, including real areas, an allocation-on-use (AOU) volume including virtual areas, and a controller allocating a non-allocated real area in a pool including the pool volumes to a virtual area corresponding to an address specified by a writing command when no real area is allocated to the virtual area, and writing data corresponding to the received writing command to the allocated real area. The controller moves data stored in all the real areas in a first pool volume allocated to the AOU volume to a second pool volume, and changes a power consuming status of the physical memory device constituting the first pool volume to a power saving mode after the data has been moved.

Abstract: It has been impossible in prior art to copy every piece of data that is stored in a virtual volume. A management computer of this invention receives a copy request that designates a real storage area as a copy source, selects a virtual storage area that is associated with plural real storage areas as a copy destination virtual storage area, and judges whether or not a copy source virtual storage area and the copy destination virtual storage area are allocated to real storage areas. Based on a result of the judging, the management computer gives an instruction to copy data that is stored in the copy source real storage area to a copy destination real storage area, and keeps information about a replication relation between the copy source real storage area and the copy destination real storage area on which the data copy has been performed.

Abstract translation: 现有技术中不可能复制存储在虚拟卷中的每一条数据。 本发明的管理计算机接收将真实存储区域指定为复制源的复制请求，选择与多个实际存储区域相关联的虚拟存储区域作为复制目的地虚拟存储区域，并且判断复制源 虚拟存储区域和复制目的地虚拟存储区域被分配给真实存储区域。 基于判断结果，管理计算机给出将存储在复制源真实存储区域中的数据复制到复制目的地实际存储区域的指令，并且保持与复制源实际存储区域和复制源实际存储区域之间的复制关系的信息 已经执行了数据拷贝的复制目的地实际存储区域。

Abstract: Conventionally, no consideration was given to the control of the main power supply circuit in a storage apparatus. Thus, unnecessary electric power will be consumed because it is not possible to inhibit the power consumption of the main power supply circuit of the storage apparatus. With this storage system having a plurality of storage apparatuses, a storage apparatus internally has a power supply control program for controlling the respective components and the main power supply circuit, and the power supply control command program provided to the management computer migrates a storage extent to be used for business to another storage apparatus based on the operation schedule of business to use the storage extent of the storage apparatus, and commands the power supply control of the main power supply circuit in the storage apparatuses and the respective components.
