  • Method of data placement and control in block-divided distributed parity disk array
    Patent number: 7653829
    Abstract: A method of data placement and control in a block-divided distributed disk array is provided. At first, data to store is divided into logical blocks, and each of the divided logical blocks is further divided into a plurality of data blocks. Then, a parity block is created through performing an XOR operation on the data blocks of each logical block in a unit of a strip, and the parity block is arranged at the first block of a strip unit. Then, parity blocks are arranged at a next block of a previous logical block's the last data block through a left/right shifting for uniformly arranging the parity blocks through out all disks in order to fill an empty block between the logical blocks.
