Abstract: Given a simulation of configurable disk arrays storage system based on multi-module. This software supports RAIDO,RAIDl,RAID3,RAID5,RAID6,and adds the RAID5x This software adopts multi-thread technology to simulate the dynamic interaction of the client and storage system. According to user configuration, this software can test the read and write performance of array on normal or degraded status. By experimental tests,the software can be a more realistic simulation of the array storage system. After further optimization, this software will be able to a simulated research platform of disk array performance, reliability, and optimization method.

Key words: Disk array, Multi-module, Configurable, Simulation
