Abstract: A management computer configured to manage one or more storage apparatuses managing a plurality of resources transmits requests to the one or more storage apparatuses to, based on one or more basic information pieces for identifying the one or more storage apparatuses, acquire as a priority configuration information on, out of the plurality of resources, resources logically closer to a host computer of the one or more storage apparatuses. The management computer receives the configuration information corresponding to the requests from the one or more storage apparatuses, and incorporates the received configuration information into configuration management information for managing the configuration information on the resources managed by the one or more storage apparatuses.

Abstract: It is provided a management server comprising a memory, a processor configured to access to the memory, and a network interface through which the management server holds communication to/from a storage apparatus and a file server. The storage apparatus includes a storage device, which is divided into pages each having a determined capacity to store data. The file server is configured to manage, on a file-by-file basis, data that is stored in the storage apparatus. The processor is configured to: obtain an I/O count per unit time of access to pages which stores data contained in the file; and compare a policy applied to the file and imbalance in I/O to a part of the data contained in the file, and output a changed policy in the case where it is found that the policy applied to the file needs to be changed as a result of the comparison.

Abstract: The present invention is provided to make effective use of a storage area, and to enhance user usability. 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: A higher-level apparatus acquires apparatus identification information identifying a physical storage apparatus including physical areas allocated to a virtual volume. The higher-level apparatus may typically be a host such as the one described above, or may be an apparatus (a switch apparatus, for example) interposed between a host and a physical storage apparatus. Based on the apparatus identification information, the higher-level apparatus selects an access path that is connected directly to the physical storage apparatus including the physical areas allocated to the access destination virtual area in the VVOL and does not extend through any other physical storage apparatus. Using the selected access path, the higher-level apparatus transmits an access request designating the address of the access destination virtual area.

Abstract: In the computer system, a storage system provides a storage level virtual volume based on thin provisioning technology, to a physical server on which a virtual machine is defined. The storage system releases the area of the logical volume corresponding to the storage level virtual volume accessed by a virtual machine which is specified to be deleted, on the basis of storage level virtual volume conversion information which is managed by the storage system.

Abstract: An example of the invention is a computer system managing actual storage areas provided by physical storage apparatuses as a single storage pool and allocating an actual storage area to a virtual volume from the storage pool when writing data to the virtual volume from the host computers. A management computer identifies, based on access path management information, access paths for access from the host computers to the virtual volume and usage status of the access paths for access to the virtual volume, and determines, based on the usage status of the access paths, target capacity ratios of actual storage areas allocated to the virtual volume from the physical storage apparatuses providing actual storage areas to the storage pool. The physical storage apparatuses allocate actual storage areas to the virtual volume based on an actual storage area capacity already allocated to the virtual volume and the target capacity ratios.

Abstract: The storage management system supports planning of volume migration between different storage apparatuses. The storage management system determines source volume groups to which the source volumes belong, determines sizes of volumes to be allocated from the storage device groups to the destination pools, determines sizes of volumes to be migrated from the source volume groups to the destination pools, creates image data indicating information on the determined sizes of volumes to be allocated and the sizes of volumes to be migrated, and outputs the image data to a display device.

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.
