    摘要: A parity-data generating unit generates, in response to a write request containing update data, updated parity data in the parity group to which the update data belongs. A time-series-information generating unit generates time-series information indicating an anteroposterior relationship during writing between the update data and existing data stored in the unit storage area to which the update data is to be written. A time-series-information adding unit adds the time-series information, generated in response to the write request, to the update data as certification time-series information and that adds comparison time-series information to the updated parity data in association with the update data, the comparison time-series information having the same value as the certification time-series information. A writing unit distributes and writes, to the multiple storage devices, the update data to which the certification time-series information is added and the updated parity data to which the comparison time-series information is added.

    摘要: An allocation control device divides the storage management devices into groups based on grouping factors. It generates group management information about each group based on the grouping factors corresponding to storage management devices belonging to the group. It obtains logical volume information about a subject logical volume to be allocated to the physical storage areas, the logical volume information indicating the capacity of the subject logical volume and a predicted capability value of the subject logical volume. It acquires the physical storage areas to which the subject logical volume is to be allocated, based on the logical volume information and the group management information. It selects one of the groups for which the maximum processing capability is higher than the predicted capability value of the subject logical volume. It allocates divisional areas of the subject logical volume to the physical storage areas in the selected group.

    摘要: In a computer for executing processing based on a storage management program, a management information storing unit designates, from the data blocks having the same content, main-data used as an access destination and sub-data used as a backup, and stores management information that registers storage nodes as allocation destinations of the respective main-data and sub-data; a load information collecting unit continuously collects load information on the storage nodes; a replacement object detecting unit detects a pair of the main-data and the sub-data having the same content and having a predetermined condition such that a load difference between the allocation destination of the main-data and that of the sub-data exceeds a predetermined allowable value; and a management information updating unit replaces roles of the main-data and the sub-data between the detected pair of data blocks.

    摘要: An allocation control apparatus allocates duplicate logical volume divided areas to virtual storage areas that do not have data storage area in the physical storage area. The apparatus associates identification information of the allocated virtual storage areas, of the duplicate logical volume divided areas, and of duplication source logical volume divided areas to be set in the management information. The apparatus detects, upon a data writing request, based on the management information, the unallocated real storage area in the logical volume divided area. The apparatus reallocates the real storage area to the duplicate logical volume divided area to update the management information. The apparatus identifies, based on the management information, the real storage area allocated to the duplication source logical volume divided area corresponding to the duplicate logical volume divided area. The apparatus copies data stored in the real storage area to the real storage area.
