1U hardware 

 

1 rack unit – a system of measurement for equipment that is mounted in a standard 19 inch (wide) IT rack. 1U is equivalent to 1.75 inches. A typical rack will be 48 U high and manufacturers will state how high their equipment is in a U measurement. It ensures that a rack can be filled with different manufacturers devices because they conform to a standard measurement system. One of the few last bastions of the Imperial measurement system used throughout the World.
