| Abstract: | Based on the analysis of device driver characters of embedded Linux, this paper presents a novel RAID algorithm to improve the storage I/O performance. It also carries out its device driver and cache management. At last, the RAID5 storage subsystem is realized. The test results and performance analysis show that the algorithm is effective and feasible. |
