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 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： 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： 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： A computer-readable medium storing a data management program makes a computer manage data redundantly stored in storage devices having storage areas split into slices for data management. The data management program realizes the following functions in the computer. A first function receives irregularity information indicating that each of one or more of the storage devices may be possibly faulty, and stores the irregularity information in a storage; and a second function determines, by reference to the irregularity information, whether or not a first storage device containing a slice to be accessed is possibly faulty, on receipt of access information indicating occurrence of a request to access the slice. When yes is determined, the second function instructs an external device to recover data stored in the slice, where the external device controls a second storage device storing redundant data identical to the data stored in the slice.
