4u-servers 

A computer server in a rackmount enclosure/case that takes up four rack units of height. A rack unit is 1.75". I know this is UrbanDictionary.com, but that other definition about it being slang for a slow server is crap.

We have two 4U servers handling database tasks in our main data center rack.
