Abstract :
Currently, approximately 1.5-3.0% of the energy produced in industrialized countries is consumed by data centers. About 40% of the energy in data centers is spent on cooling. An approach called "free air cooling," which uses ambient air to cool the equipment, is being used in the industry because it results in significant energy savings. This cooling method changes the operating conditions in data centers, which may pose reliability risks to telecom equipment. For data centers already in operation, re-qualifying the equipment is not a viable option to evaluate the risks of free air cooling because it is not practical to take equipment out of service for testing. This paper identifies the reliability risks to telecom associated with the implementation of free air cooling, and develops a prognostics-based approach to assess and mitigate those risks.
