    V Center   Fault Tolerance Scenario

    zeebahi Novice

      Hi every one,

      I am trying to understand FT, please consider following examples:

       

      Example#1

      We have  a cluster with three ESXi1, ESXi2, ESXi3 with FT enabled.  VM1 is on ESXi1 and Cloned VM1 ( created by FT) is on ESxi2.

      Assume  ESXi1 goes down, as a result Clone VM1 becomes active.  After a while , ESXi1 comes back online, What will happen next? Will VM1 will take back its role as Active VM or Cloned VM continue to be active while VM1 assumes Passive role? Is there any way we can tell V center  to give back the role when the original VM comes back online i.e VM1 should become active and Cloned VM1 should go back to being passive?

       

      Example#2

      We have  a cluster with three ESXi1, ESXi2, ESXi3 with FT enabled.  VM1( Active) is on ESXi1 and Cloned VM1 ( created by FT) is on ESxi2.

      Assumes VM1 and Cloned VM1 are running  Windows 7.  We later upgraded   VM1( Active) to Windows 8, will  Cloned VM will also be upgraded to Windows 10 automatically?

       

      Example#3

      We have  a cluster with three ESXi1, ESXi2, ESXi3 with FT enabled.  VM1 is on ESXi1 and Cloned VM1 ( created by FT) is on ESxi2.

      Assume  ESXi1 goes down, as a result Clone VM1 becomes active. We upgraded OS on  Cloned VM1 ( which is now active), will OS on VM1 ( which is now passive) be upgraded automatically?

       

       

      Thanks and have a good night!!
