What is HA and FT?
Similarly, you may ask, what is the difference between HA and FT?
The key difference between VMware's Fault Tolerance (FT) and High Availability (HA) products is interruption to virtual machine (VM) operation in the event of anESX/ESXi host failure.
Secondly, what does vSphere ha do? vSphere HA provides high availability for virtual machines by pooling the virtual machines and the hosts they reside on into a cluster. Hosts in the cluster are monitored and in the event of a failure, the virtual machines on a failed host are restarted on alternate hosts.
Also asked, what is the difference between VMware ha and VMotion?
They are two completely different technologies. VMotion migrates a running VM from one host to another. HA restarts a VM on another host if the original host disappears for whatever reason. HA does not use VMotion.
What is the difference between high availability and redundancy?
High availability means that the systems will always be available regardless of what happens. With redundancy, you may have to flip a switch to move from one server to the other, or you may have to power up a new system to be able to have that system available.
