  • Accelerated data recovery using a repeating stripe group arrangement
    Patent number: 9323616
    Abstract: A method of defining a layout mapping function for a parity distributed RAID array including a plurality of target objects, the layout mapping function defining the mapping of the group-address space to the target-address space in the array and including a matrix defining a unit space across a plurality of target objects, the matrix Includes columns defining the target objects and rows defining equally-offset sequential units on the target objects, the method including: a) defining, on a computing apparatus, a layout of stripe groups across the target objects by defining a pattern including a plurality of stripe groups into a predetermined pattern and repeating the pattern across the matrix, each stripe group including a plurality of data units and a plurality of parity units; and b) implementing, on a computing apparatus, the layout on the target objects of the RAID array.
