RAM Usage vs Demand

This post was originally published on this site

Hi,

 

I’ve been asked to determine how many new VMs we can add to our existing vSphere infrastructure. Seems an easy task but I’m getting a little bit confused looking at the metrics in vCOPS.

According to vCOPS memory usage is 76% and taking this value under consideration I wouldn’t probably create any new VMs on this host as I read that this is a good practise to keep memory usage under 80%. What puzzles me is that “Demand” us only 14% (is it memory currently used?). Which one of this metrics should I use to determine capacity in terms of RAM?
