The data center industry has experienced significant growth over the past decade with the introduction and explosion of online banking, social networking and entertainment services. As a result, power consumption of such facilities continues to grow at a rapid pace. It has become imperative that energy savings and efficiencies be pursued in these components at various levels within the data center facility. This project aims to achieve the same by replacing internal server fans with larger, more-efficient fan units at the rear face of the rack. This study will be conducted by using a cluster of 1.5U Intel based Open Compute servers. With the introduction of higher fan diameters at the rack, the fans will be characterized experimentally for its flow impedance, air flow rate, and its effect on die temperature and power consumption for various utilization levels. Since the utilization of the servers is not the same throughout the rack, it becomes important to study the impact on the server components. The experimental methods utilized in the new rack design configuration will be then compared with the existing chassis fan configuration determining the performance of the proposed system. This study will be used to establish guidelines between server or rack level deployment based on the utilization the servers are running at the stack. Thus conclusively, this study shall demonstrate the use of larger fans over server level fans, which shall save cooling power at the server level and rack level.
