This typically means blowing all the warm air out the back of the rack and directing it up and out toward the ceiling. Planning out airflow for a server rack is done so that all the equipment can move in cool air from one side, and have it flow out of the rack. Since a rack essentially contains multiple computers, it is not only important to manage airflow in each device but in the rack itself. Like a home computer, servers have intakes and exhausts, bringing cool air in from one side and hot air out of the other. Managing heat in a server can help cool down a room, lower electric bills or prevent a server from crashing. Why is Airflow So Important for Server Cooling? Choosing the right type of fans and positioning them properly allows data center managers to bring cool air in from the right places and push the hot air to where it needs to go. Server racks are designed to help manage airflow and keep the temperature at operating specifications. Server cooling presents challenges unique to the environment that a rack is in.
