One of my VMware clusters is made up of 2 hosts. Each host has 512GB of RAM and they are an HA pair. I am currently (according to vCenter) using about 38% of the RAM on each host. I continue to get suggestions in the "Assure Service Performance" dashboard to move VMs from one of these hosts to the other due to "Mem congestion on the Physical Machine".
Can someone explain to me how Ops Mgr determines there is memory congestion and how I can get that on hosts with over 60% of their RAM free?
