Air Management in the Data Center Cooling
One of the most important aspects of maintaining an efficient data center is proper air management. As servers generate heat from continuous operation, warm exhaust air needs an effective way to exit the server rack area while cool intake air is brought in. Without good circulation, hot spots can develop that negatively impact server performance and lifespan. Strategically placed vents, fans, and ducting allow for the balanced flow of air. Airflow design should account for intake requirements as well as pressure differentials between hot and cold aisles. blank spaces and impediments to the free flow of air through the racks should be avoided. Monitoring temperature and humidity levels can identify issues before they escalate.
Cooling System Design
At the core of any effective Data Center Cooling system is the design of the underlying infrastructure. Key considerations include the placement of computer rooms, selection of cooling units, and configuration of piping/ducting. Facilities located away from extremes of weather perform better. Computer rooms should have hard-walled barriers and sealed openings to contain the cool air. Redundant cooling units such as CRACs (computer room air conditioners) ensure continuous operation in case of maintenance or failures. Piping must be appropriately sized to handle the water/fluid volume without pressure drops that compromise performance. Ductwork should incorporate enough turns and vents to properly distribute cool supply air without dead spots. Proper insulation prevents condensation issues.
