What is the difference between a 1U and 2U server?

Equipment manufacturers tend to make their equipment front panel height slightly smaller than the allotted "U". A 1U rackmount server, for example, is 1.719". Likewise, a 2U or 4U server is also smaller than the allotted space by about 1/32 inch.

How many 1U servers will fit in a rack?

A standard rack is 42U of space. You can technically fit 42x 1U servers in a rack, but, you need to consider other equipment (routers, switches, cable management, etc) which will all take up space. Power consumption is probably a more likely a limiting factor then space as 42 servers is going to take a LOT of power.

How much is 1U rack space?

This unit of measurement refers to the space between shelves on a rack. 1U is equal to 1.75 inches. For example, a rack designated as 20U, has 20 rack spaces for equipment and has 35 (20 x 1.75.) inches of vertical usable space. Rack and cabinet spaces and the equipment which fit into them are all measured in U.

What is 1U or 2U on rackmount?
