Research on the disk array technology based on the GPU

In order to address to the issue that disk array technology exists a high CPU usage and low efficiency, we proposed the RAID6 checksum algorithm based on GPU-accelerating, the main research in it was RAID6 PQ generation algorithm. On the basis of RAID6 CPU checksum algorithm, we studied the characteristics of the parallel, and developed the RAID6 algorithms of GPU version. By the system testing, we compared the difference between GPU parallel algorithms and the efficiency of CPU implement, in the case of different quantity of disk and different stripe size. Then it has been proved that it can improve the efficiency of calculate and reduce the CPU utilization by implementing the RAID6 checksum algorithm on the GPU.
