一、概述 进入九十年代以来,计算机技术的发展突飞猛进,硬件成本急剧下降,应用范围波及一切领域,计算机技术的应用极大地提高了生产力和经济效益,但是由于计算机系统的可靠性问题同时也给用户带来很多麻烦,造成很大损失。据各类调查报告的结果显示,目前用户面临的最主要问题是计算机系统的可靠性和整个信息系统的健全性。 为满足广大用户对计算机高可靠性的要求,我所在“八·五”期间开始了研制高性能抗恶劣环境容错计算机的工作。作为其一个重要组成部分,我们从故障率比较高的磁盘入手,
I. Overview Since entering the nineties, the development of computer technology by leaps and bounds, the sharp decline in the cost of hardware, the scope of application spread to all areas, the application of computer technology has greatly improved productivity and economic benefits, but due to the reliability of computer systems also give Users bring a lot of trouble, causing great losses. According to the results of various survey reports, the most important issue currently facing users is the reliability of the computer system and the integrity of the entire information system. In order to meet the requirements of the users for the high reliability of computers, I started the work of developing high-performance anti-harsh environment fault-tolerant computers during “August 5”. As an important part of it, we start with the higher failure rate of the disk,
