A rack server is a server mounted inside a rack. Rack servers are typically general- purpose servers that support a broad range of applications and computing infrastructure. The racks stack servers vertically to save data center floor space. The more equipment that admins can stack vertically, the more equipment they can house. Standardized racks are measured in units (U’s) that are 1.75 inches tall and 19 inches wide. Rack servers fit into these dimensions by vertical multipliers, meaning that rack server heights may be 1U, 4U, 10U, or higher, like the 10 foot tall 70U rack that came out in 2016. Additional devices are also manufactured to fit the rack unit standard, so companies can make use of empty units in their racks.
