Hi,

 

I am back :-)

 

Some more questions:

 

HTSplit and vCMP - is same rule about even and odd virtual cores apply to vCMP guest? What when we have 1 vCPU vGuest?

 

ASM - according to KB ASM is using highest numbered core for part of control plane tasks. Same rule about halting 80% of odd core still applies here - so ASM control plane processes will be throttled to 20% if even core is loaded over 80%?

 

Is ASM really limited for those selected control plane task to one and only one core? I've seen configs where highest numbered core was almost constantly loaded 90-100% - I assume mainly by ASM control plane, if only one core can be dedicated to ASM what is an option in such case?
