摘要： A storage system is adapted for efficiency by defining beforehand a first size, which is the maximum data that can be read at one time, a second size, which is equal to or less than the first size, and a third size, which is a factor of the first size. A controller provides a virtual volume comprising a plurality of virtual pages. Upon receiving a write request, the controller allocates a pool area comprising a plurality of stripes of the first size, stores the write request data in a cache, and when writing the data stored in the cache to the storage device, compresses the data in accordance with the third size unit, selects a storage area in accordance with the second size unit, and writes the compressed data to the selected second size storage area sequentially from the start address of a free area without leaving spaces therebetween.

摘要： A storage system according to the present invention has a plurality of flash packages equipped with a deduplication function. When a storage controller transmits a write data and a feature value of write data to a flash package, the flash package compares contents of the write data with data having a same feature value as the feature value of the write data. As a result of the comparison, if there is no corresponding data, the write data is stored in the flash memory, but if there is a corresponding data, the new data will not be stored. Thus, a greater number of data can be stored in the flash memory while preventing deterioration of performance.

摘要： As a method for migrating data of a volume adopting a snapshot function to a new storage system, in order to perform migration without depending on a method for compressing snapshot data of a migration source storage system, and without stopping transmission and reception of data between the host computer and the storage system, at first, after migrating data of a volume being the source of snapshot (PVOL), migration is performed sequentially from newer generations. At this time, migration target data of each SVOL is all the data within the migration source storage system. The SVOL data copied to a migration destination storage is compared with one-generation-newer SVOL data within the migration destination storage system, and based on the comparison result, a difference management information is created. If there is difference, a VOL allocation management table is updated, and difference data is stored in the area allocated within the pool.

摘要： A storage system 100 includes a storage apparatus 125 and a storage controller 115 configured to control the storage apparatus. The storage controller adds a predetermined flag 425 to every predetermined size of data requested by a host computer to be written to the storage system, and stores the resultant data in a cache memory 278C. Upon detecting a predetermined trigger for saving, the storage controller stores, in a nonvolatile memory 284, data with the flag added thereto out of the data stored in the cache memory. The storage controller detects, as unsaved data information 620, a data size and a storage location for data with no flag added thereto out of the data on the cache memory, and stores the detected unsaved data information in the nonvolatile memory in association with the data with the flag added thereto.

摘要： If resources allocated to a host computer exist in different physical storage nodes within a virtual storage system after performing migration to a storage system, mapping of resources among the physical storage nodes becomes necessary, and if the amount of communication between physical storage nodes that occurs during access to resources exceeds a bandwidth of the connection path, the host I/O performance may be deteriorated compared to the performance before migration. Therefore, when migration is performed from a first physical storage node to a virtual storage system composed of a plurality of second physical storage nodes, a management computer allocates resources of the second physical storage nodes within a range of bandwidth of the transfer path between the second physical storage nodes based on configuration information of the plurality of second physical storage nodes, performance information, and load information of the volume provided by the first physical storage node.
