摘要： A management device obtains, from the plurality of storage nodes, information of accesses which are made to the actual storage areas included in the storage nodes, generating load information of the actual storage areas based on the access information, and storing the generated load information in a load information storage unit. The device changes, based on the load information stored in the load information storage unit, the assignment relations of the actual storage areas with respect to the virtual storage areas such that loads of the storage nodes are leveled. The device instructs the plurality of storage nodes to move the data in the actual storage areas depending on change in the assignment of the actual storage areas to the virtual storage areas.

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 multinode storage system, a virtual disk associated with a storage device to be connected is created, and a slice of a connected storage device is allocated to one segment of the virtual disk. Next, one slice of data in the storage device to be connected is copied to the connected storage device. The rest of data in the storage device to be connected is divided into slices, which are allocated to segments of the virtual disk. Then, metadata of the rest of the slices is written into a management information area in which copying of the data therefrom has been completed.

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.

摘要： A data allocation control program manages data allocation when data is distributively stored in a plurality of disk nodes that are shifted to a power saving mode unless access is performed for a certain time. The program produces a plurality of allocation pattern candidates each indicating the disk nodes in which the respective data are to be stored. The program calculates a no-access period expectation that represents an expected value of occurrence of a no-access period during which access is not performed to some of the disk nodes. The program selects as an allocation pattern for data reallocation, one of the plurality of produced allocation pattern candidates with the largest calculated no-access period expectation. The program instructs the disk nodes to reallocate the respective data in accordance with the selected allocation pattern.

摘要： A computer in a disk node executes a data management program. A deduplication-eligible data unit detection module detects a data unit whose deduplication grace period after last write time has expired. A deduplication address fetch module interacts with an index server to obtain a deduplication address associated with a unique value of data stored in a constituent storage space allocated to the data unit that is found to be deduplication-eligible. A constituent storage space deallocation module stores the obtained deduplication address in a data unit record memory, together with information indicating the detected data unit. Simultaneously a constituent storage space deallocation module releases the allocated constituent storage space from the detected data unit.

摘要： In a computer executing processes based on a storage management program, an attribute collection unit collects attributes of storage nodes. A group creation unit creates at least two groups that include the storage nodes, in accordance with the attributes of the storage nodes collected by the attribute collection unit. A data allocation unit allocates distributed data and redundant distributed data to the groups created by the group creation unit in such a manner that the distributed data and the redundant distributed data having the same content as the distributed data are placed in different groups.
