Cooling Data Center CostsBy Samuel Greengard | Posted 2010-08-13 Email Print
Roughly 40 percent of the energy consumed in data centers is a result of cooling systems, and that figure is rising. Reversing that trend is possible, and could mean big savings.
One of the hottest opportunities for greening the data center lies in cooling.
According to Booz & Co., roughly 40 percent of the energy consumed in data centers is a result of cooling systems, and that figure is rising. Here’s what Booz recommends to increase cooling efficiency:
• Optimize airflow in the data center to reduce the mean gradient temperature and reduce cooling requirements.
• Use a hot/cold aisle configuration, in which equipment racks are arranged in alternating rows of hot and cold aisles.
• Rely on air handlers to better control airflow within the data center and enable more efficient cooling.
• Deploy smart cooling energy-management systems with sensors to reduce energy consumption by as much as 40 percent.
• Increase cooling temperature targets to slightly above the data center baseline temperature. Every added degree results in an estimated
4 percent reduction in energy consumption.
• Install renewable cooling sources such as outside air during the winter—where practicable—to minimize usage of internal cooling systems.
