【摘要】 为了保证服务器对外服务的持续性,提高服务器的可靠性,双机容错服务器是一种较好的解决方案。通过引入集群技术设计了高可用双机容错服务器的硬件容错体系,使用自检和心跳等多种软件容错技术实现了运行于该容错服务器之上的容错管理系统,最后对该容错系统给出了可用性分析。更多还原

【Abstract】 Dual fault-tolerance server is a good solution to guarantee the durative of servers’ services and to enhance the reliability of ser-ver.Based on cluster technology,the hardware architecture of high-available dual fault-tolerance server is designed.Many software fault-tolerance methods are introduced into this platform such as self-check,heartbeat etc.And thus,a fault-tolerance management system running on this platform is realized.At last,availability of the fault-tolerance system is analyzed.更多还原
