    Several empty slots per U unit in a network server rack

    Always leave a few U of empty space — around 10–20% of your total capacity. It helps with airflow, cooling, and future growth without having to rearrange your setup. Rack Units, or “U,” are the standard way to measure how much space a device takes up in a server rack. The “U” system solved that by bringing uniform height measurements, so servers and devices from different. Blanking panels are the most simple and cost effective method for improving air flow efficiency in data center server racks.
