How well does VMware HA work?

It works so well, in fact, that you may not even notice it working. …
I had been out for a few days working on-site with customers, and when
I came back into the lab this morning everything seemed fine. It
wasn’t until later in the day, when I finally launched the Virtual
Infrastructure (VI) Client and connected to VirtualCenter,
that I realized one of my ESX hosts had crashed. VMware HA had stepped
in and automatically restarted all the VMs on the second host, and the
other engineers who were there when the failure happened said they
didn’t even notice the failover. Had I not logged in to the VI Client,
I wouldn’t have even known that I had a host failure. It was that
seamless.
