I've got a system where we create a handful devices periodically on Vcenter servers spread out geographically, we build in one "pod" or another. The load starts out the same and grows in a rather unpredictable way. (i.e. we don't have enough information going in to decide if one load that we're deploying is going to be larger or smaller than average). The devices come and go, but the device load mostly grows.
So, when I want to deploy a new set of devices, I have to choose between POD A and POD B, it's something like 15 ESX Servers in either POD. Is there a cumulative way to tell if POD A or POD B currently had more or less load so I could maintain a balance between the two VCenters?
