Recent technology advancements by IT equipment manufacturers have
resulted in high heat-producing hardware that pushes the envelope
of traditional air cooling methodologies. In response, various
infrastructure vendors have introduced “liquid-cooled” cabinet
solutions that can accommodate as much as 30 kW per cabinet or
more. Here, we examine the energy efficiencies of the various cooling
solutions available today and some possible cooling solutions that
may be introduced in the near future.
We reduced the myriad of cooling solutions available today to
five distinct scenarios, and then added three additional scenarios
that may become available. These scenarios are analyzed individually
to quantify what energy efficiencies (or inefficiencies) are inherent
for each.
