摘要： A second storage maps a migration source volume to a virtual volume of a migration destination volume according to storage virtualization technology. A host system including a host switches an access path from an access path to the migration source volume to an access path to the migration destination volume. The second storage executes copy processing of migrating, from the migration source volume to the migration destination volume, data in an assigned area of a virtual volume according to thin provisioning of the migration source volume based on the information contained in the first thin provisioning information in the first storage, and copying that data from the migration destination volume to a virtual volume according to thin provisioning of a copy destination volume in the second storage. The second storage associates the virtual volume of the copy destination volume with the migration destination volume in substitute for the original virtual volume.

摘要： In general, a DRAM is used as a cache memory, and when attempting to expand the capacity of the cache memory to increase the hit ratio, the DRAM is required to be physically augmented, which is not a simple task. Consequently, a storage system uses a page, which conforms to a capacity virtualization function (for example, a page allocatable to a logical volume in accordance with Thin Provisioning), as a cache area. This makes it possible to dynamically increase and decrease the cache capacity.
摘要翻译：通常，将DRAM用作高速缓冲存储器，并且当试图扩大高速缓冲存储器的容量以增加命中率时，需要物理地增加DRAM，这不是一项简单的任务。因此，存储系统使用符合容量虚拟化功能（例如，根据精简配置的可分配给逻辑卷的页面）作为缓存区域的页面。这使得可以动态地增加和减少高速缓存容量。

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.
