A Data center is the heart of our associated world. It is a facility that houses computer systems and related components. According to IDC, because of enormous increment in pattern of IoT (Internet of Things) and distributed computing the introduced limit of server farm workloads will increment by around 750% around 2014 and 2019. Data center spaces can consume up to 100 to 200 times as much power as standard office spaces. With such huge influence utilization, they are prime focuses for vitality proficient outline measures that can spare cash and lessen power use. In a regular Data center with an exceptionally effective cooling framework, 50% of the data energy is consumed by the IT equipment. Utilization of effective IT hardware will altogether lessen these heaps inside the Data center, which subsequently will scale back the gear expected to cool them. Introduction to air-water cooled system will help us achieve more effective cooling of IT equipment while reducing the power consumption. Air-water hybrid gives us the flexible design choices. This hybrid system cools the high heat generating components using water and the rest of the components are cooled using the internal fans. Air cooling is the conventional way of cooling for IT equipment and it suffice for cooling of components with low thermal demand. In addition, air cooling is cheap, easily available and has high serviceability than rest of the cooling methods. The objective of this work is to optimize the airflow through one such air-water cooled server in order to achieve effective cooling power. Since, the high heat generating components are cooled by water, the other components will need less volume of air for cooling. Also the inlet air can be at much higher temperature to achieve cooling following ASHRAE standards. In the following work, we develop a detailed server model using software 6SigmaET® equivalent to the reference server to study the air cooling part and optimize the airflow. The supply airflow rate is simulated by varying the speed of fans to see the volume of airflow in the system. It is then seen for less number of fans or changing number of fans to study the airflow in the system. Thus, the efficiency of the cooling power due to air cooling is studied.
