    摘要： Backup and restore operations are made possible in a storage system that has dynamic chunk allocation (DCA) capability. In a DCA storage system, a chunk of physical storage area is not allocated to a segment of a volume until a write command is received targeting the segment of the volume. During a restore operation of the volume in the DCA storage system, the wasting of storage capacity when a backup image of the volume is restored is mitigated by preventing allocation of physical storage areas to segments of restore data that are only void data.

    摘要： A controller in local site can process a request for storage resources from requestors like host computers, backup servers and tier manager. The controller checks own resource information including information about storage resources in the local site, according to requirements based on the request. The controller also asks other controllers in remote sites to check storage resources in each remote site. The controller in the local site collects the answers about available storage resources (including resources in the local site) under the requirements and selects storage resources to be used. Then the controller in the local site notifies the selected storage resources to the requester. Release of storage resource can also be performed with communication between controllers. Computers and backup servers can utilize these functions provided by the controllers to obtain and release the storage resources.

    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.

    摘要： With a computer system having a host computer and first and second storage apparatuses, the second storage apparatus virtualizes first logical units in the first storage apparatus and provides them as second logical units to the host computer, collects configuration information about each first logical unit, and sets each piece of the collected configuration information to each corresponding second logical unit. The host computer adds a path to the second logical units and deletes a path to the first logical units. The second storage apparatus copies data stored in the first logical units to a storage area provided by the second storage device and associates the storage area with the second logical units.

    摘要： A path is formed between a host computer and storage apparatuses without depending on the configuration of the host computer and a network and a plurality of volumes having a copy function are migrated between storage apparatuses while keeping the latest data.A computer system includes a host computer and first and second storage apparatuses, wherein the second storage apparatus virtualizes a plurality of migration source volumes as a plurality of migration destination volumes and provides them to the host computer; and if the second storage apparatus receives an input/output request for each migration destination volume, it reflects data in each migration source volume via each migration destination volume and the host computer cancels a path to each migration source volume and registers a path to each migration destination volume; and if the second storage apparatus receives a write request, it writes write data to each migration destination volume and each migration source volume and migrates copy processing control information and data until the termination of migration processing.
