摘要： A storage system comprises a virtual volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. The controller of the storage system manages which actual areas are assigned to which virtual areas and the access load on the actual areas assigned to the virtual areas. The controller, if the access load of a first actual area assigned to a first virtual area is inappropriate for a first actual area group comprising the first actual area, migrates data to a second actual area in a second actual area group which is appropriate for the access load of the first actual area from the first actual area. The controller performs data migration between actual areas for achieving data allocation at a certain point of time based on history information which is the information related to a virtual area at a point of time in the past and an actual area assigned to the virtual area. Data allocation is the allocation of data in a virtual area to an actual area in an actual area group.
摘要翻译：存储系统包括由多个虚拟区域构成的虚拟卷和由不同性能的多个实际区域组配置的池。存储系统的控制器管理哪些实际区域被分配给哪些虚拟区域和分配给虚拟区域的实际区域上的访问负载。控制器，如果分配给第一虚拟区域的第一实际区域的访问负载不适用于包括第一实际区域的第一实际区域组，则将数据迁移到适合于第一实际区域的第二实际区域组中的第二实际区域从第一实际区域访问第一实际区域的负载。控制器在实际区域之间进行数据迁移，用于根据作为与过去时间点的虚拟区域有关的信息的历史信息和分配给虚拟区域的实际区域，在某个时间点实现数据分配。数据分配是将虚拟区域中的数据分配给实际区域组中的实际区域。

摘要： A storage system is provided which is capable of realizing a remote copy function for speeding up lines virtually by satisfying such demand to distribute copy data into a plurality of lines. In a storage system for connecting a local storage device and a remote storage device via a plurality of lines, the local storage device includes a remote copy program for distributing data of a plurality of logical volumes accessed from a host computer into a plurality of paths on the basis of status of the plurality of paths interposing the plurality of lines, to perform a remote copy from the local storage device to the remote storage device. Accordingly, the local storage device distributes data of the logical volumes into the plurality of lines to copy the data to the remote storage device, resulting in speeding up the lines virtually.
