Great criteria breakdown. Can't argue with any of those.

Mark over at Lanamark was inspired to list factors that influence
reusing older hardware as hosts too. Check out

-Find the Machines that are up to the task. Generally if you ask the question “does this machine support VT?” you get the answer which machines are capable.

-Find Underutilized Servers. If you try to get something out of a bloated machine you will most probably get nothing.

-Estimate upgrade costs to bring them up to the task. Yes it is very probable that servers less than 3 years old can be up to the task but upgrades (a bit of memory here and there, storage over here) can not be avoided.

-Calculate the ROI for performing this task including man hours, extra costs, cost savings etc.

There is a purpose to repurpose older servers as virtualization hosts only if they are newish, underutilized and total cost of upgrade does not make sense both now and in the long run.

Sometimes we do get indecisive and do get mixed up in our choices. The choice parameters off the above question are known to us since we started virtualizing stuff. Some of those parameters and choices are the essence of the virtualization argument.

I would be happy to hear arguments or something i missed out of the equation.

No doubt. An Enterprise License agreement tends to encourage a company
to virtualize everything they can! There is not much better than seeing
all those available ESX licenses in VirtualCenter!!
