I have a Windows 2008 R2 Enterprise Exchange server currently running 4 sockets and 1 core per socket. CPU usage hovers around 75-85% so I was going to add more power. I think I found that cores vs sockets were the same in VMWare so it doesn't make a difference if I go to 8 sockets and 1 core or keep the 4 sockets and up it to 2 cores per socket. I also saw where Enterprise will support 8 sockets.
The real question: is there a preferable way so that the Windows software doesn't balk at the change? I've seen articles saying that some OS's do not like changes to the CPU.
Second question: if I change it and Windows blows up, is it reversible just by backing the sockets back down to what they were? Would a snap before shutting the VM down and adding more CPU help in this case? Thanks
