摘要： When a volume belonging to a first storage tier is relocated to a second storage tier, in the event that an empty volume satisfying capacity conditions is not present in the second storage tier, an empty volume satisfying the capacity conditions within volumes belonging to a third storage tier is virtually allocated to the second storage tier, a further virtual empty volume is formed, and the volume is virtually relocated to the further virtual empty volume.

摘要： In a system comprising a first storage system providing plural first logical volumes including real logical volume and a virtual logical volume with a host, a second storage system having a second logical volume, and a management computer, when the first storage system receives an access request to the virtual logical volume, it accesses a second logical volume associated with the virtual logical volume. In this system, when the management computer receives a request to guard one of the plural first logical volumes, it checks whether a target first logical volume of the request is a real logical volume or a virtual logical volume, in case of the virtual logical volume, generates and provides a possible at least one option to guard the virtual logical volume by considering a program for volume guard, which each of the first storage system and the second storage system has.

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 first virtual storage and a second virtual storage share an external LU (Logical Unit) inside an external storage. The first virtual storage comprises a first LU, which comprises multiple first virtual areas and conforms to thin provisioning, and an external capacity pool, which is a storage area based on the external LU, and which is partitioned into multiple external pages, which are sub-storage areas. The second virtual storage comprises a second LU, which comprises multiple second virtual areas and conforms to thin provisioning. In a data migration from the first LU to the second LU, for a data migration from a first virtual area, to which an external page has been allocated, to a second virtual area, the first virtual storage notifies the second virtual storage of a migration-source address, which is an address of the first virtual area, and an external address, which is an address of the external page that has been allocated to this virtual area, and the second virtual storage stores a corresponding relationship between the notified migration-source address and external address.
