How many compartments in the network rack are 1U

Usually, equipment like servers, routers, and switches is designed in multiples of rack units—for example, 1U, 2U, or 4U—each denoting the amount of vertical space that they occupy in a rack. To illustrate, a 2U device will occupy the same space as two 1U . U (rack unit, RU) is a unit of equipment height in a 19" rack. Important: U describes height only, but a server's real "capabilities" are also determined by chassis depth, internal layout, airflow, rails, power, and expansion (PCIe/risers, NVMe. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high. The rack unit size is based on a standard rack specification as defined in EIA -310.
