VMware High Availability Failover Simulation
Having working as a presales consultant, I have realize as virtualization gets more complex, more and more people are confused with the basic fundamental and have forgotten and felt uncertain. Certain test are also perform wrongly or understand incorrectly. Here is a short video to demonstrate this on how VMware High Availability (HA) test is conducted and configured as stated in this KB .
