| 摘 要： | 主要从如何减少系统的平均修复时间MTTR和增加系统的平均无故障时间MTTF两方面来提高系统可用性。首先据可信性的定义公式提出提高可信性的措施,如自主运算、面向恢复计算等。最后,深入研究高可用性系统的关键技术,数据存储技术、系统软件技术、进程检查点和迁移技术、故障检测技术、冗余和备份技术。

| Abstract: | There were two ways to improve the availability,one of them is to decrease the mean time to repair(MTTR),the other is to increase the mean time to fail(MTTF).The measures of improving the availability were brought forward according to the formula of availability,taking the Autonomic Computing and Recovery-Oriented Computing for example.In the end,the key technologies of high availability were deeply studied,such as data storage,system software,process checkpoints,process transfering fault detecting,redundac... |
