This session will review the limitations of all air cooling in high-density data centers, including air-cooled chillers and direct-adiabatic cooling. Alongside the introduction of direct immersion cooling, single-phase and two-phase liquids, as well as the introduction of Cold Plate cooling using liquid inside the server to directly cool the processor, HP and other manufacturers are now offering turn-key solutions for a liquid-cooled server farm using technology from Kray, which is owned by HP.

We will present a new solution using available products on the market today in a new and novel way. The key feature is a single process water loop that provides 90 deg F water for direct liquid cooling and 73 deg F water for conventional air cooling. A project currently in design will be presented showing how tenants will be able to use conventional air cooled IT equipment and liquid cooled IT equipment in the same white space environment.

The solution has a working PUE of less than 1.15 and uses 85% less water than a conventional cooling tower solution.
