Abstract:
Objective To build high availability cluster using VMware to improve availability of hospital information system.Methods Virtual machines were installed in VMware server to act as backup servers.High availability software continuously detected status of physical servers using heartbeat signals.Results When physical servers failed,high availability cluster switched services automatically.The business switched to virtual machine quickly and smoothly.Conclusion High availability cluster based on VMware can improve HIS availability and lower implementation costs effectively.
