Use Solid Wall Cabinets

Cabinets used to have holes in the tops and bottoms, and quite often the sides were removed when installing multiple cabinets. That meant that an entire row of cabinets may not have any inside walls, except for the two ends. As you add more servers to the cabinet, the air simply finds the path of least resistance to the top of the cabinet. What path was that? Right through the path you created between the cabinets – the cooled air would just pass up the servers, leaving them much too hot. With today’s front-to-back-cooled server, the cabinets are designed to force the air to go in through the front and pass through the servers too. These racks minimize the number of holes in the top and bottom, and have solid, non-removable walls on all sides. This ensures that the airflow through the cabinet and servers is evenly distributed and consistent.
