Hi Guys and Girls,
I would like to ask a question about vCenter HA Capacity for admission control. I have 29 machines that are all powered on on one of the cluster. Servers in that cluster are due to expiry so we have to decomission them.
These 29 machines use 163 GB of memory. We are planning to buy two hosts that have 262 GB of RAM each and they will be in the cluster which means whole cluster capacity will have 524 GB of RAM. Of course we will move these machines to the new cluster.
My question would be what percentage for Admision Control I should set for this Cluster. I was planning to reserver 25 percent of memory but not sure about my math. As I said there will be only 2 hosts in this cluster and HA should be able to move all machines to another host if one goes down.
Do I have enough capacity for these virtual machines and what percentage I am supposed to put for Admission Control
Thanks in advance
