I often speak to people who prefer a virtual machine protected by VMware HA for hosting their vCenter Server instead of using vCenter Server Heartbeat but vCenter Server Heartbeat offers some real great benefits compared to VMware HA. VMware HA only works with virtual machines and protects the operating system and hardware. HA also needs shared storage. vCenter Server Heartbeat is able to clone, synchronize and do real-time replication. vCenter Server Heartbeat works with either virtual machines or physical machines and protects the operating system, the hardware, and the application. You don’t need shared storage but redundant storage. I’ve created a little demo movie showing the vCenter Server Heartbeat console and a real fast switchover to the secondary server.
