Fresh air could save millions in data center cooling costs, Intel has claimed, after a successful experiment in the New Mexico desert.
Replacing air conditioning by piping in outside air saved power costs, with no appreciable increase in server failure rates, Intel concluded in a research paper (PDF). Despite a lot of dust and major temperature changes--both long considered undesirable in data centers--the equipment wasn't affected, Intel said.
"Servers...were subjected to considerable variation in temperature and humidity, as well as poor air quality; however, there was no significant increase in server failures," the paper said. "… Read more
