  • Method and apparatus for writing data to a disk array
    Patent number: 7831768
    Abstract: A method for writing data to a RAID 5 configuration of hard disks writes two or more items of data to a data stripe together. The method includes the determining of the suitability of data items to be written together, the storing of the new data items to temporary buffers, the reading of the original data and parity from the hard disk to the temporary buffers, the modification of the parity and the writing of the new data and new parity to the hard disks.
    Type: Grant

  • RAID ARRAY
    Publication number: 20080104445
    Abstract: A method of providing a RAID array, comprising providing an array of disks (202a-202f), creating an array layout (200) comprising a plurality of blocks (D1-D26, P1-P10) on each of the disks (202a-202f) and a plurality of disk stripes (204a-204j) that can be depicted in the layout (200) with the stripes parallel to one another and diagonal to the disks, and assigning data blocks (D1-D26) and parity blocks(P1-P10) in the array layout (200) with at least one parity block per disk stripe.

  • Method and system for storing data
    Publication number: 20060085674
    Abstract: The present invention relates to methods for storing data and relates to a method for storing a plurality of stripes across a plurality of disks; wherein each stripe is comprised of a plurality of segments, wherein each segment is comprised of a first data chunk, a second data chunk, and a parity chunk being the parity of the first and second data chunks, and wherein all the chunks within a segment are stored on separate disks. In a preferred embodiment, each stripe includes at least one spare chunk.
