Know What You’re Cooling Bob Blough, director of product marketing at Liebert Precision Cooling (www.liebert.com), says too often data center managers rely on a building’s general air-conditioning system to cool their data rooms and then are caught off guard when a hot spot in the middle of the room generates a server failure.
“While comfort cooling from the building’s basic air-conditioning system may keep parts of a small data center cool, it often isn’t reaching the hot spots nearest the servers—the areas that really matter,” Blough says. “Placing racks near air ducts is a temporary solution at best and unrealistic as you add servers and racks.”
Andy Yother, engineering manager at Canvas Systems (www.canvassystems.com), suggests looking to new technologies for hot aisle containment and in-row cooling. “These technologies reduce the need to chill an entire data center and can make a huge impact on cooling requirements by reducing the total volume of air that must be cooled,” he notes. At the same time, he says that using hot aisle containment technology is usually more cost-effective in new builds rather than in retrofit situations.
