Abstract
A storage apparatus includes a first storage device and a processor. The first storage device is configured to store therein first information blocks used to recover second information blocks stored in a second storage device. The processor is configured to read the first information blocks from the first storage device in an order of addresses of storage areas of the first storage device. The processor is configured to output part of the first information blocks which have been read from the first storage device to respective recovery destinations of the second information blocks to recover the second information blocks step by step.
Claims8
A storage apparatus, comprising:
- a first storage device configured to store therein first information blocks used to recover second information blocks stored in a second storage device;
- and
- a processor configured to
- read the first information blocks from the first storage device in an order of addresses of storage areas of the first storage device, and
- output part of the first information blocks which have been read from the first storage device to respective recovery destinations of the second information blocks to recover the second information blocks step by step.
A storage system, comprising:
- a second storage device configured to store therein second information blocks;
- and
- first storage apparatuses each including:
- a first storage device configured to store therein first information blocks used to recover the second information blocks, and
- a processor configured to
- read the first information blocks from the first storage device in an order of addresses of storage areas of the first storage device,
- output part of the first information blocks which have been read from the first storage device to respective recovery destinations of the second information blocks,
- receive information blocks from other first storage apparatuses, and
- recover one of the second information blocks step by step on basis of the received information blocks.
A computer-readable recording medium having stored therein a program that causes a computer to execute a process, the process comprising:
- reading first information blocks from a first storage device in an order of addresses of storage areas of the first storage device, the first information blocks being used to recover second information blocks stored in a second storage device;
- and
- outputting part of the first information blocks which have been read from the first storage device to respective recovery destinations of the second information blocks to recover the second information blocks step by step.
