2U Tower Server
1U size is the standard one that measures 1.75-inches of rack height. Therefore, a 2U rack mount is 2 x 1.75, i.e., 3.5 inches in height. Individual power supplies are mounted within the rack-mounted enclosures that need integral power. In such cases, the power supply might be shorter than the server’s overall height. It is known for improving the capability and usability of the device while saving the physical space for the components that facilitates airflow and better cooling mechanisms for heat dissipation.
