‘Cool’ Ideas Abound for Data Centers

Linda Hardesty

The higher temperature ranges and increased humidity levels set for data centers by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) have spawned innovative ideas for data center cooling, according to the Wall Street Journal.

For instance, REI is utilizing evaporative cooling at its data center near Seattle, Wash. REI’s retrofit led to a 93 percent reduction in the energy needed to cool the data center, according to WSJ, adding that the data center had a PUE rating of 2.4 prior to the project and now aims for a PUE below 1.4.

The Wall Street Journal story also cited Syracuse’s Green Data Center, which is using waste heat from its onsite natural gas-fired microturbines. Syracuse partnered on its Green Data Center with IBM and the New York State Energy Research and Development Authority.

  1. There is still a long way to go. Most prefer to forget the waste of energy internal to the server caused by fans working harder at the higher temperatures.
    PUE might drop but power consumption may remain the same as the cooling load moves from chiller to server fan where it is counted as IT load.
    Simple physics indicates that air is very bad at cooling.Moving to liquid will not only reduce power consumption but also increase power density so that much smaller data centers are needed
