  • What does 4u mean in a switch

    What does 4u mean in a switch

    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 devices in the rack. The height of a rack is measured in Rack Units, written as U. 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. What is a Rack Unit (U)? A Rack Unit (often referred to as just “U”) is the unit of measure that equipment racks use to describe the vertical space they have. One rack unit is equal to a height of 1.
