Providing fault tolerance protection
vSphere Fault Tolerance (FT) provides protection from a host or storage hardware failure for critical virtual machines by enabling a secondary running copy of the virtual machine running on a separate host and stored on a different datastore. The secondary virtual machine is identical to the primary protected virtual machine, and the failover is instant and transparent:
vSphere FT Fast Check-Pointing keeps the primary and secondary virtual machines in sync in order to allow the secondary virtual machine to instantly take over should the primary virtual machine be impacted by a host or storage failure.
