Modelling and Evaluation of Distributed Airflow Control in Data Centers

摘要: In this work a suggested method to reduce the energy consumption of cooling system in data center is modelled and evaluated. Introduced different approaches distributed airflow control, which amounts can be supplied parts (instead an even distribution). Two kinds control are compared traditional approach without control. The difference between two being type server rack used, either ones or new kind with vertically placed servers. A model capable describing power for these was constructed. Based on model, MATLAB simulations three load scenarios were then carried out. It found that introducing reduced all had largest reduction. For case could 60% - 69% initial consumption, depending workload scenario. Also examined effect parameters process variables (parameters held fixed help feedback loops), as well optimal set point values.
