... sensor data inside the data centers to help predict the data center temperature field as a function of the air flow rates of computer room air conditioning (CRAC) units. The approach is demonstrated through application to an operational data center of 102.2 m 2 (1100 square feet) with a hot and cold...

... for saving on air-conditioning equipment and energy. Whereas until now uninterrupted operation was the only focus (and data centers were ready to spend any amount of resources to achieve it), the current economic climate has shifted the focus to energy conservation. A “green data center” is a new goal...
