Thermal Facts & Fairy Tales: Whatever Happened to the Predicted Data Center Energy Consumption Apocalypse?

 

As the title indicates, since the middle of the last decade, there have been very pessimistic projections regarding the growth of the total annual energy used by data centers in the U.S. One of them suggested that by 2030, the energy consumption in the U.S. in the IT sector would be roughly 60% of that used by its entire industrial sector. [1,2,3] What was the origin of this … [Read more...]

Managing Cooling Fan Noise In Product Design

 

ABSTRACT Cooling fan noise is a system property determined as much by thermal and mechanical design and fan selection as by a fan’s acoustical design. While even the quietest fan can be used in a noisy manner, a significant fraction of unpleasant surprises can be avoided. NOMENCLATURE C                          Numerical constant D                        … [Read more...]

DCIM And Deepmind, Take 2: AI to Control Google’s Data Center Cooling 

 

Readers of Electronics Cooling will no doubt recall our blog Of Deepmind, DCIM, and Data Center Cooling published two years ago where we highlighted some of the good design practices Google uses to improve (i.e., decrease) Power Usage Effectiveness (PUE) metric in its data centers. In that blog we cited one metric for average PUE that steadily decreased from 1.20 in 2008 to … [Read more...]
