Hi guys,
I read this vsphere 5 documentation (vSphere Documentation Center) and found this statement;
"Consider the vSphere HA admission control reservations when determining the number of virtual machines and the amount of resources that your cluster supports. vSphere HA admission control reserves 33% of all CPU and memory resources in a 3-member VSA cluster and 50% of all CPU and memory resources in a 2-member cluster. vSphere HA admission control makes the reservations to ensure that resources are available when virtual machines need to be restarted from a failed ESXi host onto a running ESXi host."
So If I have 2-member VSA cluster with total physical spec is:
12-core CPU
64GB memory
After consider 50% for HA admission control, does it mean I only have 6-core CPU and 32GB memory efficiently usable?
I really hope someone can make me crystal clear regarding this matter.
Thank you
