摘要

S-RAID 5 is an energy-efficient RAID for sequential data access, an energy management algorithm, logical space forecast (LSF) algorithm, for S-RAID 5 was proposed to improve the performance of S-RAID 5 while maintains its energy efficiency. LSF performed dynamical cluster analysis on the addresses of the I/O requests, and obtained the areas of I/Os distributed in the logical address space. According the dynamic characteristics of above areas and special data layout of S-RAID 5, LSF forecasted the states of the disks in S-RAID 5, and scheduled the disks based on the predicted states. Experimental result shows that compared with classical algorithms TPM and Markov, LSF can effectively eliminate the response time delay of S-RAID 5 while gains similar energy saving.
