磁盘驱动器的节能取决于I/O流量中包含的空闲间隔。本文提出了一种算法，挖掘两个块的相关性，其中包含长空闲时间间隔和有限数量的零星I/O请求。挖掘的空闲间隔足够长，可以通过切换磁盘电源状态和过滤零星的I/O请求来节省能源。我们的实验结果与真实系统的痕迹表明，现代的I/O流量包含了大量的空闲时间间隔，可以用来节省能源。
The energy conservation of disk drives depends on the idle intervals contained in I/O traffic. This paper proposes an algorithm for mining the two block correlations which contain long idle intervals and limited number of sporadic I/O requests. The mined idle intervals are long enough for energy conservation by switching the disk power states and filtering the sporadic I/O requests. Our experimental results with real-system traces show that the modern I/O traffics contain a lot of idle intervals which can be used to save energy.
