摘要： An object of the present invention is to allocate a volume to an appropriate tier in a pool in accordance with the performance of the volume. Multiple tiers 1K are created in a pool 1B. A pool volume that matches the performance required by a tier is allocated to each tier. An information acquisition part 1D acquires information related to respective storage apparatuses 1, 2, and information related to the performance of each volume. A tier control part 1E allocates a pool volume to any tier of the respective tiers, based on the performance information.

摘要： A storage cluster including a first storage apparatus and a second storage apparatus is defined. Communication between the first storage apparatus and the second storage apparatus uses a first network and an access request from a host computer uses a second network. Each of the first and second storage apparatuses defines internal LUs by using storage devices included in that storage apparatus. The first storage apparatus defines other internal LUs by using internal LUs of the second storage apparatus and the second storage apparatus defines other internal LUs by using internal LUs of the first storage apparatus.

摘要： Multiple types of storage devices which have different performance are appropriately allocated to multiple virtual volumes in accordance with the performance requirements of the respective virtual volumes. In cases where, among virtual volumes 82 for which response times have been specified, there is a [virtual volume] that has a shortage of pages to which SSDs 70 should be allocated and that does not satisfy the performance requirement when its Tier boundary value β is adjusted to Tier boundary value β′ and, if unallocated pages as the pages to which SSDs 70 should be allocated do not exist, Tier boundary value γ or Tier boundary value α of another virtual volume is adjusted to Tier boundary value γ′ or the Tier boundary value α′, and pages to which SSDs 70 are allocated are secured in the virtual volume 82 for which the Tier boundary value has been adjusted.

摘要： A pool is replicated in the unit of volume providing the pool, and when a physical device is blocked, any volume blocked in the pool is changed to the replicated volume so that the pool and a virtual volume can be recovered. With such a configuration, when any pool or virtual volume is blocked due to blockage of any volume providing the thin provisioning function, volume recovery can be swiftly performed without changing the virtual volume used by a host computer, and consumption of storage resources needed therefor can be suppressed.

摘要： To provide a storage management device capable of performing restore at a high speed. In the storage management device that manages backup and restore of data stored in a storage device, a temporary restored image is created by applying each required delta image to the full backup image, a reverse delta image before the application of the applied delta image is created, and a number of delta application blocks concerning the applied delta image is recorded as cost information of applying delta. The delta backup restore unit determines a restore method by comparing a number of blocks, which is changed when restore is performed by applying each piece of the reverse delta image, with a number of blocks, which is changed when the restore is performed by applying each delta image, with reference to the cost information of applying delta.
