Abstract: The virtual volume is a virtual logical volume that conforms to Thin Provisioning, and is a logical volume configured from a plurality of virtual areas and used by a plurality of applications. In a case where the storage apparatus receives a write request comprising write-destination information for identifying a write-destination virtual area in the virtual volume, and, in addition, the write-destination virtual area is an unallocated virtual area, the storage apparatus selects a medium, which corresponds to the write to the write-destination virtual area and/or the identification information of the source of this write, from a plurality of media, which have different performances and which are each configured from two or more real areas, and allocates a real area from the selected medium to the write-destination virtual area.

Abstract: An object of the present invention is to efficiently use a hierarchical pool. A management server manages performance information of multiple host computers, and based on each performance information, determines whether a prescribed host computer, which comprises a load of equal to or larger than a preconfigured prescribed threshold, exists among the multiple host computers. The management server creates a reallocation plan, which stipulates an allocation amount of a real storage area for each of multiple storage tiers, with respect to a prescribed virtual logical volume used by the prescribed host computer. Based on the reallocation plan, the management server decides a corresponding relationship between each logical storage area and each real storage area of each storage tier, and notifies a storage apparatus of this corresponding relationship.

A management apparatus determines a reallocation destination of each logical storage area on the basis of an access load on each logical storage area by a host computer and an allocation status of each logical storage area in a storage-destination storage tier. A monitoring mode selection part for selecting any one of multiple monitoring modes selects a prescribed monitoring mode from the multiple monitoring modes on the basis of allocation time information related to a time at which each logical storage area is allocated to an allocation-destination storage tier.

Abstract: The present invention measures an actual utilization frequency of data and controls a location of this data in a storage apparatus in a case where a host computer makes joint use of a storage apparatus and a cache apparatus. A portion of data used by an application program 1A is stored in a storage apparatus 2 and a cache apparatus 3. A management apparatus 4 detects an I/O load of a page (4A), and detects an I/O load of cache data (4B). The management apparatus 4 determines a corresponding relationship between the page and the cache data (4C), and adds the I/O load of the cache data to the I/O load of the page.

Abstract: The management system identifies a server level virtual volume corresponding to a storage level pool on the basis of storage management information and server management information, and displays information relating to the correspondence between the storage level pool and the server level virtual volume. The storage management information represents correspondence between a storage level virtual volume to which a portion of an area is allocated from the storage level pool by thin provisioning technology at the storage level, and the storage level pool. The server management information represents correspondence between a server level virtual volume to which a portion of an area is allocated from the storage level virtual volume belonging to a server level pool by thin provisioning technology at the server level, and the storage level virtual volume.
