University report: Increased web usage could heat up data centers

Colleges have long looked for ways to save energy in the cooling of server racks.

Data centers across the world are set to use 19 percent more energy this year than they did in 2012, and while colleges and universities look for environmentally-friendly alternatives to energy inefficiency, there could be two innovative ways to cool ever-churning server racks.

Schools have long experimented with ways to keep data centers from overheating without pumping air conditioning at its coldest temperatures all hours of the day – a problem faced by internet giants such as Google and Netflix that have adjusted to constantly increasing web usage worldwide.

A study published in the March 29 edition of the journal Science outlines two ways companies and colleges could cope with increasing user demand without ramping up traditional cooling mechanisms in expansive campus data centers. Diego Reforgiato Recupero, a computer scientist and electrical engineer at the University of Catania in Italy, said “smart standby” and dynamic frequency scaling could be key parts of the green effort to cool down server rooms.…Read More
