磁盘阵列中的聚散技术研究

Study on Using Scatter/Gather Operation in RAID

将聚散技术应用于磁盘阵列中，解决由命令合并引起的数据移动问题，提高阵列 性能。在实时操作系统环境下实现算法，并进行测试，其效果显著。

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.
