Hi
I have a cluster with 2 ESXi 4.1 each host has 128GB, total mem in the cluster: 256GB
Currently we have granted to the Vms 98GB.
In case of hardware failure in one of the host, we will have 128GB of Ram available for the vms and we are okey.
My question is: how many 8GB vms can I add to the cluster to be sure that HA can power on all the vms with a good performance?
My calculations
128GB*1.3 (overcommit relation)=167GB so i can add aprox 8 new vms with 8GB of Ram
Which is the best overcommitmen relation for production server Phisical mem x 1.3? or 1.4?
Regards
Federico
