| 摘 要： | 在VMware服务器中安装多个虚拟机,分别作为不同服务器的备用机,并且利用心跳信号持续检测物理服务器的工作状态.当物理服务器出现故障时,高可用性集群自动切换服务,使故障服务器的业务迅速平衡地迁移到虚拟机上,也可以把负载过大的服务器上的应用动态地分配到其他负载较小的服务器上,以确保电力信息系统服务的不间断运行.

| Abstract: | VMware machines are installed in VMware servers to act as backup servers, The heartbeat signal is used to continuously detect the working status of the physical servers. When a physical server fails, the high availability cluster could automatically switch services, in order that the failing server＇s operations migrate rapidly to a virtual machine. In the same way, the server applications with too much load could be dynamically allocated to the server with smaller load, to ensure the uninterrupted operation of the power information system. |
