I have been thinking about how I can test my Fault Tolerance machines. But I can't seem to come with a proper test.
How can I possibly calculate the time it took for VMware to switch from the primary virtual machine to the secondary one?
Ping the VM and kill the host where the primary runs, how many pings do you loose? This should give you a feeling for the time it takes vSphere to switch from the primary virtual machine to the secondary.
