摘　　要：磁盘阵列的故障处理系统是保证其可靠性的核心模块之一。为了提高磁盘阵列的可靠性,文章中设计了一种故障主动处理系统。该系统根据磁盘阵列的组成模块和命令执行过程,将命令的执行分为6个阶段,故障处理系统监测命令的执行过程并主动检测发生的故障。当检测到故障发生时,故障主动处理系统能够主动进行处理。通过对系统的实际测试和评估,得出该故障主动处理系统能够显著提高磁盘阵列系统的可靠性,并降低了开发的难度。Aim.To our knowledge,there is no paper in the open literature dealing with the design of a fault active handling system for disk array.Section 1 of the full paper explains such a design;its core is： ＂The disk array system is based on the composition of the module and the command implementation process,the implementation of the command is divided into six stages;when the fault address the initiative to obtain and monitor the implementation of the order process and the failure happened.When the fault occurs,the fault handling system is able to take the initiative to proactively deal with the fault.＂ Section 2 is entitled evaluation and analysis;it evaluates the Raid controller in Ref.2;it presents the test results in Figs.4 and 5 and gives Table 1 to compare the performance of the Raid controller with an ordinary fault handling system with that of a Raid controller with our fault active handling system.On the basis of Figs.4 and 5 and Table 1,we believe that our fault active handling system can significantly improve the reliability of the disk array system and facilitate the development.
