Enabling Fault Tolerance in VMware vSphere 6.5

If we want to provide full high availability to a virtual machine, we will enable Fault Tolerance or FT. With FT we will be able to allow a VM in the event of a failure of a host or the storage where it is executed to fall, Don't worry., since the VM is replicated to another host and another datastore. The magic of FT will cause us to only lose a single packet against the VM!

Using VMware FT

Another new feature of VMware vSphere 4 is the ability to use Fault Tolerance or FT. It is the ability to have real high availability, This is, with previous versions of VMware, we had DRS, that if a physical host went down, the virtual machines running on it, they run on another host, Foresaw a restart of the virtual machines. What VMware FT gives us is the possibility that virtual machines do not have to be restarted, and in case of ESX host crash with virtual machines, those that are protected with FT will continue to run on another host without loss of service.
