vSphere Fault Tolerance will soon support SMP

Came across this session in the VMworld 2011 lineup – (BCO2874 vSphere High Availability 5.0 and SMP Fault Tolerance – Technical Overview), according to the description the Fault Tolerance feature which previously only supported VM’s with a single vCPU will soon support vSMP. Providing this support has been a major development challenge for VMware as it is not an easy task to keep multiple CPUs in sync via lockstep. In fact I talked to VMware about it at the vSphere 5 launch and they said they were working with the CPU vendors to see if they could make it easier for them to do this. Well looks like they finally found a way, it will be interesting to see what they come up with, sign up for the VMworld session to find out more including a live demo. Since it’s not currently in vSphere 5.0 I’m guessing it may make it into a point release like vSphere 5.1.
