“How-to” Guide for Transitioning from Air to Liquid-cooled High Performance Computing Systems

The Energy Efficient HPC Working Group (EE HPC WG) has a Liquid Cooling How-to Team that has written a document and is producing an educational video series to encourage the adoption of liquid cooling in supercomputing and, more generally, high performance computing. 

This guide is intended for people who are responsible for operating data centers that contain high performance computing equipment and haven’t yet transitioned from air to liquid cooling. It gives advice for taking an incremental, "small-steps how-to approach" for transitioning without a lot of re-do and cost. It assumes that you already have a data center with air cooled equipment, and that some modifications will be needed to support liquid cooling. 

This guide was written with extensive review and input from many other people who are active members of the EE HPC WG. This guide is intended to bring a much needed "small-steps how-to approach" to transitioning from air to liquid cooling and to leverage, without replicating, a lot of excellent work already published by the Energy Efficient High Performance Computing Working Group (EE HPC WG), ASHRAE TC9.9, the Open Compute Project (OCP) and The Green Grid. 

For many, liquid cooling may seem like a confusing and overwhelming landscape. This next part of the introduction provides a useful typology of liquid cooling technologies to help resolve confusion.
