Abstract:

We evaluate the existing trade-off between the exhaust flow rates and temperatures on a air-cooled Open Compute Windmill V2 server platform. To this aim, we implement a novel flow provisioning controller that optimizes the server's exhaust air temperature, and compare its performance against that of the default provisioning strategy. We report both experimental and numerical results that link the attainable flow rates and the exhaust temperatures. We demonstrate thus the benefits of tailored control strategies in a heat recovery context, and provide crucial characterizations toward the investigation of data center heat recovery applications.
