We currently have 3 VMware Hosts running VMware ESXi, 5.5.0, 2718055
The hosts are HP DL360p Gen8 currently with 128GB physical RAM installed.
We are entertaining the idea of upgrading the memory in each host and would like some opinions from the real world as to how difficult (or easy) this may be. Is there a physical memory size limit (VMware specific)?
Is it as simple as buying memory and plopping it in? Is there any configurations needed on the host level or within the hypervisor?
