ABSTRACT:
Systems and methods for using a graphics processor to perform RAID parity functions may improve disk access performance. A method is provided for configuring a graphics processor to perform XOR parity computations when data is written to the RAID array. Another method is provided for configuring the graphics processor to perform the XOR parity computations to restore data when a disk is damaged. Using the graphics processor as a coprocessor to offload parity computations from a central processing unit may improve disk access performance and overall system performance.
