基于SCSI的容错磁盘系统之设计与评估

DESIGN AND EVALUATION OF A FAULT TOLERANT DISK SYSTEM BASED ON SCSI

摘要: ＳＣＳＩ接口以其可靠性高、数据传输速率快且支持大存储容量而广为采用．文中介绍了一个基于ＳＣＳＩ接口的容错磁盘系统的设计，并提出了时钟级同步、热插拔、自诊断、系统恢复等一系列新思想，从而使得本系统具有普通ＳＣＳＩ磁盘系统没有的功能特点．最后通过可靠性分析得出本系统可靠性比普通ＳＣＳＩ磁盘系统大为提高的结论．

Abstract: A fault tolerant disk system based on SCSI is introduced, and some new ideas are suggested. The conclusion of high reliability is arrived at.
