How to Choose Suitable “U” Server Rack

The label of “U” on a server rack indicates one server rack unit. The Institute of Electrical and Electronics Engineers (IEEE) standard setting organization has determined the standard sizes for server rack components. Server racks provide a modular, configurable space in which to install a variety of computer equipment.


The height of 1U on a server rack is 1.75 inches. Rack-mounted components will come with a rack unit number. Some servers are 1U while others may be 2U, 3U or 4U; the only limit is the size of your server rack. A 42U server rack is the standard size for data centers, though short 24U racks are common in smaller office installations.



The IEEE standard width for a rack mounted device is 19 inches. However, server racks are wider than the 19-inch internal size. Server racks can be between 24 and 32 inches wide; choosing a wider server rack will provide more internal space for cables to be tucked away.


Sever rack depth varies greatly as it is the only U measurement that is not standardized. Server racks can range from 18 to 42 inches deep to facilitate different depth components and server installation spaces. However the 40- and 42-inch deep racks are the most widely used.



While server type computers are the most common components installed in a server rack, they are far from being the only options. Hard drive arrays are configured to mount in server racks, often so the drives can be swapped in and out without powering down the unit. Network routers and switches are often installed in server racks along with uninterruptable power supplies (UPS). There are also fans, drawers and shelves that can all be installed using the standard rack unit configuration.
