摘要
目的:利用VMware Infrastructure构建虚拟服务器集群,提高医院信息系统的可用性、安全性。方法:在VMware Infrastructure平台上构建多个虚拟机,所有虚拟机集中存贮在磁盘阵列上,集中管理所有的VMwrae服务器和虚拟机。结果:当虚拟平台中的任一物理服务器出现故障时,其上的虚拟服务器动态迁移其他服务器,实现了服务不中断。结论:充分提高医院信息系统的高可用性,优化了IT架构,提高了服务器的利用率,节约了医院的投资成本。
Objective To improve availability and safety of HIS by building high availability server cluster using VMware Infrastructure. Methods Several virtual servers were established in VMware Infrastructure platform and stored in the magnetic-disc-array collectively; all the VMware servers and virtual servers were managed in a centralized way by one donated computer. Results When one of the physical servers based on VMware Infrastructure failed to work, the virtual server running on this failure one would migrate automatically to another so that service work would continue. Conclusion With IT structure optimized and efficiency of physical servers increased, this method improves the security and availability of HIS and saves hospitals' investment.
