We have a 3 node cluster with an ESX 5 Essentials license applied. This limits us to 3 nodes and 192 gigs of memory in total IIRC.
I am wondering what happens with the memory allocation and what control we have over it. Each server has 96 gigs of physical memory, meaning 2 nodes will cause us to hit the memory limit. I added the 3rd node but don't see any indication of it being limited in terms of memory limitiations. didn't see any obvious log warnings either.
Is the vmemory licensed amount a limit on memory in use by guests, or a limit on the physical amount of memory in totoal amongst the 3 nodes? if the total amount of physical memory, can you modify the amount each host is entitled to? (in our case the VMs all run on the first 2 nodes with the 3rd as a 'stand by/sandbox', due to it being an older machine with less cores and other resources).
thanks for your time,
