摘要: 研究了高可用系统的结构,介绍了一种高可用系统的实现。在分析系统失效因素和高可用系统结构的基础上,对主要的失效部分(软硬件)进行冗余以提高服务器、磁盘、网络可靠性,据此采用有效的失效探测与恢复机制,实现了一个能够保证整机容错,无单点失效的高可靠系统。Abstract: This paper describes the research and implementation of high availability system.By way of analyzing the system failure factors,a no-single-point-failure high availability system architecture is presented which uses the hardware and software redundancy technique to ensure server,disk,network reliability and privides efficient failure recovery.The implementation method is also given.
