Hotter might be better at energy-intensive data centers

26.09.2012
New research suggests that turning up the temperature could save energy with little or no increased risk of equipment failure

As data centres continue to come under scrutiny for the amount of energy they use, researchers at University of Toronto Scarborough (UTSC) have a suggestion: turn the air conditioning down.

"We see our results as strong evidence that most organizations could run their data centers hotter than they currently are without making significant sacrifices in system reliability," says Bianca Schroeder, a UTSC assistant professor of computer science.

As data centres have proliferated they have required more energy, accounting now for about 1 percent of global electricity usage. A sizeable fraction of that is the cooling necessary to keep the machinery functioning properly.

But in a paper called Temperature Management in Data Centers: Why Some (Might) Like It Hot, Schroeder and her UTSC colleagues found that warmer temperatures than are normally recommended might be able to save energy without negatively impacting equipment reliability and longevity.

Data centres typically operate at temperatures from 20C to 22C. Estimates show that just 1 degree increase in temperature could save 2 to 5 percent of the energy the centres consume. Schroeder says that most data centres could probably increase temperatures much more than that.

To conduct the study, the researchers collected data from data centres run by Google, Los Alamos National Labs, and others. They also directly tested the effect of temperature on equipment performance in their lab. Their data showed that higher temperatures either weren't associated with negative effects on the equipment, or else the negative effects were smaller than predicted.

The paper can be found here http://dl.acm.org/citation.cfm?id=2254778. It was presented at the ACM Sigmetrics conference in London in June.

It was co-authored by Nosayba El-Sayed, Ioan Stefanovici, George Amvrosiadis and Andy A. Hwang.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
