Abstract: The paper analyzes the parallel storage system control strategy whic h combines the I/O sub-commands, and the paper notices that the combination ind u ces the in-memory data movement which increases the system cost. the paper bri ng s out an improved strategy that utilizes Scatter/Gather operation in parallel st orage system. It implements and measures the strategy in real time operating sys tem environment. The result shows that this strategy has excellent performa nce.
