Tonight I’ve been reading the post It Costs Money to Be Cool!”. This post breaks down the costs of cooling a data center. The interesting number here for me is that 13% of the cooling cost is for the UPS (presuming a classic AC powered data center with a standard AC-DC-AC UPS).
From my previous articles, we know that implementing a DC powered data center gains about 20% in power efficiency. Presuming that the cooling load generated by the UPS is evenly split between the AC-DC and DC-AC conversions and that we eliminate the DC-AC conversion with the DC power plant, we’re not only gaining 20% in power efficiency with DC power, we’re reducing cooling load 6-7% in the process!
Could there REALLY be a reason NOT to do this?
