Green Grid Argues That Data Centers Can Lose the Chillers
Nerval's Lobster writes "The Green Grid, a nonprofit organization dedicated to making IT infrastructures and data centers more energy-efficient, is making the case that data center operators are operating their facilities in too conservative a fashion. Rather than rely on mechanical chillers, it argues in a new white paper (PDF), data centers can reduce power consumption via a higher inlet temperature of 20 degrees C. Green Grid originally recommended that data center operators build to the ASHRAE A2 specifications: 10 to 35 degrees C (dry-bulb temperature) and between 20 to 80 percent humidity. But the paper also presented data that a range of between 20 and 35 degrees C was acceptable. Data centers have traditionally included chillers, mechanical cooling devices designed to lower the inlet temperature. Cooling the air, according to what the paper originally called anecdotal evidence, lowered the number of server failures that a data center experienced each year. But chilling the air also added additional costs, and PUE numbers would go up as a result." -
Microsoft, Google Battle Over Energy Efficiency
1sockchuck writes "Microsoft and Google have opened a new front in their battle for global domination: data center energy efficiency. Just weeks after Google published data on the extreme efficiency of its previously secret data centers, Microsoft says it has achieved similar results with shipping containers (despite Google's patent) packed with up to 2,500 servers. The geeky benchmark for the battle is Power Usage Effectiveness (PUE), a green data-center metric advanced by The Green Grid. Microsoft says its containers tested at a PUE of 1.22, while Google reported an average PUE of 1.21 for its data centers, which apparently are also now using containers."
