Which two statements are true regarding a mixed DRS cluster with Intel-based and
AMDbased ESXi 5.x hosts? (Choose two.)
A.
Storage vMotion will not be available for this cluster
B.
DRS can load-balance running virtual machines, assuming multiple hosts per CPU
family.
C.
HA can only failover virtual machines to hosts within the same CPU family.
D.
Cold Migration may be needed to balance the performance load on the cluster
Explanation:
Interesting stuff : http://tspeedtech.com/35/
vSphere HA wil (might) work with mixed vendor CPUs, as it starts VMs in a powered off state
However FT requiring EVC is not compatible
vMotion to a mismatched host won’t work for sure, so does DRS.
The main question is here : Can DRS take into account there are mismatched host ?
D is wrong : as you might have an inbalance between the host with AMD the others with Intel. So at a certain stage you are done with balancing in same CPU vendor.
As vMotion is not possible you have to stop and register the VM on another host. This can only be done if the vmx is not locker or in a powered of state
