We have struggled with CPU spikes often running 100% today. Sage 100 ERP 2013 a server based ERP program running on a Windows 2008 64-Bit Standard VMWare Server. Box is a Free ESXi 5.0 HP DL 380 Gen 7 server.
Below is a PNG of the current ESXi settings. It has 6GB RAM and seems to use less than 2GB.
My question is this, can I or should I increase it from 1 CPU to 2 CPUs? Do i need to put it in Maintenance Mode to change the number of CPUs?
If I cannot increase it to 2 CPUs because it is free version that will speed up the purchase of vSphere Essentials that is already in the works. I know that will allow 6 CPUs, 2 for each server.
