esxi cluster configure Fault Tolerance

What is Fault Tolerance:
VMware vSphere Fault Tolerance (FT) provides continuous availability for applications (with up to four virtual CPUs) by creating a live shadow instance of a virtual machine that mirrors the primary virtual machine. If a hardware outage occurs, vSphere FT automatically triggers failover to eliminate downtime and prevent data loss.

After failover, vSphere FT automatically creates a new, secondary virtual machine to deliver continuous protection for the application.

Steps:


  • Configure Vcenter server with 2 esxi servers with HA enabled.
  • Create vmkernal network with Vmotion and Fault Tolernace enabled, provide IP for the same.
  • Create shared 2 datastores primary on esxi server1 and secondary on esxi server2.
  • Create VM and right click ,enable FT selecting the secondary datastore as destination.
