  • Patent number: 9182926
    Abstract: A storage apparatus coupled to a host device comprises a virtual volume which is a virtual logical volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. A controller manages pool status information which is the information showing which actual area is allocated to which virtual area and access load related to the virtual areas. A management system of the storage apparatus, with reference to the pool status information at multiple points of time from past to present and an access load threshold which is equal to or larger than 1, estimates the used capacity of each actual area group at points of time in the future, calculates the installed/removed amount of each actual area group which is the difference between the estimated used capacity and the current storage capacity, and performs the processing based on the calculated result.

  • Patent number: 8775765
    Abstract: A physical storage area that is allocated to an unused area of a virtual volume is removed. A management unit sends a request to a server computer to make every piece of data stored in a first logical volume migrate to a second logical volume. The server reads all the data out of the first logical volume and writes the data in the second logical volume. A storage system that includes the first logical volume and the second logical volume allocates a physical storage area to an area of the second logical volume where the data is to be written, and writes the data in the allocated physical storage area. The storage system then deletes the first logical volume.

  • Patent number: 8543778
    Abstract: A storage system comprises multiple virtual volumes (VVOLs) and multiple pools. Each pool is configured of multiple actual area groups of different performances. The storage system accesses actual areas assigned to virtual areas identified by access commands from an access source. A controller manages pool condition information which is the information showing which actual area is assigned to which virtual area and the access load related to the virtual areas. The management system of the storage system comprises management information showing a performance requirement and a performance for each VVOL. The performance of a VVOL is the performance identified with reference to the pool condition information.
