I have a single DL380 G5 running the ESXi Free for my own use. Currently has 3 VM's:
1. Windows 2008 R2 (DC/File)
2. Windows 2008 R2 (Exchange 2010)
3. Windows XP (Sage PC, used for accountant's remote access)
Server currently has 8GB (8x1GB) sticks of RAM, and its getting to be too slow. I want to upgrade it to 16GB (which is probably over what I need currently, but opens up avenues or more VM's if I want to do some testing)
Being a low utilisation server (just me really, plus a handful of external exchange only users), I dont mind cutting "some" corners.
What's the difference between Registered and Non-Registered? ECC and non ECC? Buffered and non-Buffered?
Would I get away with getting RAM which has none/only a few of these features? Would the server complain or let me even use them at all?
I know what is best - but not sure what I can get away with.
