    摘要: The present invention creates a pool comprising tiers corresponding to the performance of logical volumes.A first storage apparatus either acquires or measures the performance of multiple external pool volumes of an external storage (S1711 through S1714), and creates a pool volume group based on the performance of the external pool volumes (S1715, S1716). The rank order of a tier is decided in accordance with the performance of each pool volume group (S1717, S1718). This makes it possible to relatively easily create a pool comprising multiple appropriate tiers that are suited to the current situation.

    摘要: The present invention provides high-speed copying of a compressed data volume.The control unit of the storage apparatus divides the pool into a plurality of chunks comprising a plurality of pages storing data, compresses data which is written to the logical volume by the host and assigns one of the plurality of chunks to a compressed data logical volume which stores the compressed data, and, when the compressed data logical volume is copied, the control unit makes the page length of the chunk which is assigned to the compressed data logical volume which is the copy source the same as the page length of the chunk which is assigned to the compressed data logical volume which is the copy destination.

    摘要: Storage apparatus and data management methods provide for high-speed copying of a compressed data volume. A control unit of the storage apparatus divides a pool into a plurality of chunks including a plurality of pages storing data, compresses data which is written to a logical volume by a host, and assigns one of the plurality of chunks to a compressed data logical volume which stores the compressed data. When the compressed data logical volume is copied, the control unit makes a page length of the chunk assigned to the compressed data logical volume that is a copy source equivalent to a page length of the chunk assigned to the compressed data logical volume that is the copy destination.

    摘要: Proposed are a storage system and a data recovery method capable of guaranteeing data recovery processing at a service level sought by a user. This storage system and data recovery method uses one or more data recovery candidate points and specifies a section containing the journal and the replication of write data, checks a redundancy relation of a write range in the volume of write data written from host into the volume contained in the journal regarding one or more the journals in the section, and executes redundancy elimination processing of merging a plurality of the replications of write data or a plurality of the journals into a single replication of write data or a single journal based on the check result.

    摘要: When an event occurs in a storage system that is not recognized by a host, it is not possible to recover data at the point before and after this event. Provided is a storage system including a first storage area storing data to be used by a computer, and a second storage area for storing updated data and its update log information when there is an update request from the computer to the first storage area. This storage system monitors its own storage system and detects an event, and creates a recovery point and its update log information based on the event. When the storage system receives a recovery command at a certain recovery point, it recovers data of the first storage area at the time of recovery point by writing, in a replication storage area at a certain point of the first storage area, update data up to the recovery point among the update data stored in the second storage area.
