摘要
由于越来越多的应用受限于I/O,存储系统正起着越来越重要的作用。磁盘阵列RAID是一种提供高性能I/O的最常见存储设备。本文分析了RAID并行I/O调度算法的I/O执行时间和磁盘利用率,为合理配置高性能阵列提供了依据。
As more and more applications are I/O constrained, the storage system is playing an increasingly important role. RAID is the most common storage device to provide high-performance I/O. This paper analyzes the parallel I/O scheduling algorithms used in RAIDs, and provides some hints for the configuration of a high-performance RAID.
