Abstract
A data management apparatus, system and method are provided. The data management apparatus performing storage processing and readout processing of data for a plurality of storage devices includes a division unit that divides the data into two or more pieces of divided data, a storage destination selection unit that selects, as storage destinations for the pieces of divided data, two or more different storage devices mounted on the data management apparatus, and a distributed storage control unit that stores the pieces of divided data divided by the division unit in the storage destinations selected by the storage destination selection unit in a distributed manner.
Claims19
A data management apparatus performing storage processing and readout processing of data for a plurality of storage devices, comprising:
- a division unit that divides the data into two or more pieces of divided data;
- a storage destination selection unit that selects, as storage destinations for the pieces of divided data, two or more different storage devices mounted on the data management apparatus;
- and
- a distributed storage control unit that stores the pieces of divided data divided by the division unit in the storage destinations selected by the storage destination selection unit in a distributed manner.
A data management system including a plurality of storage devices capable of storing data and a data management apparatus performing storage processing and readout processing of the data for the plurality of storage devices, comprising:
- a division unit that divides the data into two or more pieces of divided data;
- a storage destination selection unit that selects, as storage destinations for the pieces of divided data, two or more different storage devices mounted on the data management apparatus;
- and
- a distributed storage control unit that stores the pieces of divided data divided by the division unit in the storage destinations selected by the storage destination selection unit in a distributed manner.
A data management method in a data management apparatus performing storage processing and readout processing of data for a plurality of storage devices, comprising:
- a division operation of dividing the data into two or more pieces of divided data;
- a storage destination selection operation of selecting, as storage destinations for the pieces of divided data, two or more different storage devices mounted on the data management apparatus;
- and
- a distributed storage control operation of storing the pieces of divided data divided in the division operation in the storage destinations selected in the storage destination selection operation in a distributed manner.
A management apparatus, comprising:
- a microprocessor capable of separating data;
- a selection unit capable of selecting a plurality of storage devices mounted on the management apparatus for storage of the separated data;
- and
- a controller outputting the selection.
