Power densities above 10Kw - 12Kw per rack require liquid-cooling. Very few hosting companies have built out liquid-cooled facilities because the market demand is just not there. I have not seen any such providers. Anyone?

Subject: [ Cloud Computing ] Data Center Costs Structures
This is a little off topic: please excuse me if you find this the case but I've been looking for a forum for this question for a while and have concluded the most expertise on this subject is here. If you are aware of a more appropriate forum I would be grateful for direction to it....
In looking at roadmap for IT efficiencies, there are a bunch of toolkit items at our disposal.
These include virtualization, cloud for elastic compute volumes, power management, and hardware upgrade.
As part of modeling out comparative cost / benefit for each we have investigated upgrades to racking systems which provide very high density per square foot.
What we have found is that the economic benefit of these very high density systems, which comes primarily from space and power cost reductions, is *apparently* not available to us in a colo or hosted environment because the space providers support neither the power density required nor the metered powering which would make the power savings apparent.
Is anyone here aware of a tier one data center provider who will provide metered power at densities in excess of 25Kw / rack?
