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： A storage system comprises a plurality of flash packages comprising a plurality of flash chips, and a storage controller for receiving a first write request from a higher-level apparatus and sending a second write request of write data based on data conforming to this first write request to a write-destination flash package, and demonstrates a capacity virtualization function for causing a storage capacity to appear larger than an actual storage capacity for the higher-level apparatus, and for configuring a storage space using page units. The storage system generates a second VOL (logical volume) based on a first VOL, manages a plurality of VOLs comprising the first VOL and one or more second VOLs generated based on the first VOL as a VOL group, and allocates the same page to areas of the same address of the plurality of VOLs configuring the VOL group.

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： Data migration can be preformed between source and target storage subsystems without stopping exchanging data between a host computer and each of the storage subsystems. After a next access path, which should be set instead of a specific access path in an available state among access paths, is set between the host computer and a migration target logical unit via a host port and a target port, the status of the next access path is set to an available state and the status of the specific access path is set to an unavailable state. After the next access path is set to an available state, data is migrated from a migration source logical unit of the source storage subsystem to the migration target logical unit of the target storage subsystem.

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： The amount of data to be stored in a semiconductor nonvolatile memory can be reduced and overhead associated with data processing can be reduced. When a microprocessor 112 receives a write request from a host computer 300 and data D1 to D3 exist in a cache slot 117, the microprocessor 112 reads the LBA of each piece of the data, manages each piece of the data D1 to D3 using a bitmap table 118 by associating them with their LBAs, generates a specific command CMD based on the LBAs of the data D1 to D3, adds the data D1 to D3 and addresses ADD1 to ADD3 indicating where the data D1 to D3 are to be stored, to the specific command CMD, and sends it to an FMPK 30. The FMPK 130 stores each piece of update data in a specified block in the flash memory 135 based on the specific command CMD.

摘要： Two or more first storage control apparatuses (DKC) comprise two or more virtual volumes and two or more storage devices, and a pool, which is configured by multiple actual areas, is formed on the basis of the two or more storage devices. A second DKC determines, for each storage device, an unused capacity to be given to the first DKC with respect to each first DKC based on an unused capacity of each storage device and a request value of each storage device for each first DKC, and gives, for each first DKC, the unused capacity for each storage device determined with respect to the first DKC, to this first DKC. The request value of the storage device is based on a performance value, which is a value related to the performance of this storage device. The total capacity of multiple actual areas allocated to one or more virtual volumes by the first DKC is equal to or less than the unused capacity given with respect to each storage device.
