Abstract
A first storing unit stores therein information on a communication status relating to installing positions of a plurality of storage devices forming a disk array. A selecting unit selects a plurality of storage devices for storing data, based on stored information. A second storing unit stores recovery data recovered from a storage device from which a failure is detected from among the storage devices forming the disk array in selected storage devices in a striping manner.
Claims11
A device for performing a recovery control of data stored in a storage device from which a failure is detected from among a plurality of storage devices forming a disk array, the device comprising:
- a first storing unit that stores therein first information on a communication load relating to installing positions of the storage devices;
- a selecting unit that selects a plurality of storage devices for storing data, based on stored first information;
- and
- a second storing unit that stores recovery data in selected storage devices in a striping manner.
A method of performing a recovery control of data stored in a storage device from which a failure is detected from among a plurality of storage devices forming a disk array, the method comprising:
- storing first information on a communication load relating to installing positions of the storage devices;
- selecting a plurality of storage devices for storing data, based on stored first information;
- and
- storing recovery data in selected storage devices in a striping manner.
A computer-readable recording medium that stores therein a computer program for performing a recovery control of data stored in a storage device from which a failure is detected from among a plurality of storage devices forming a disk array, wherein
- the computer program causes a computer to execute:
- storing first information on a communication load relating to installing positions of the storage devices;
- selecting a plurality of storage devices for storing data, based on stored first information;
- and
- storing recovery data in selected storage devices in a striping manner.
