That's correct. The capacity availability number is the result of analyzing the utilized resources, available resources, HA configuration settings, resource contention, and most definitely the calculated (or manually set) VM size. For more details on how the capacity availability is calculated, see the product documentation.
Hi,  Is it possible in Capacity Manager or anywhere else in vOPS to see what the potential for adding new VMs is for adding resources to ESXi hosts in a cluster. Currently, I can see how many more VMs are possible if given specific resources that currently exist on ESXi hosts in a cluster. I was wondering if there was a way to see if I added more memory to each ESXi host how many more VMs would be possible then. Also, if I increased the size of the data stores can I get specific stats on how many more VMs could be accomodated with these new resources?  Thanks.  Fernando
