Any standard 19-inch rack with a minimum depth of 29 inches to a maximum of 35 inches from front to rear rails with 42U height can be an ideal rack solution for Cisco UCS equipment. However, rack size can vary based on different requirements and the data center's landscape. The rack should provide sufficient space for power, cooling, and cabling for all the devices. It should be designed according to data center best practices to optimize its resources. The front and rear doors should provide sufficient space to rack and stack the equipment and adequate space for all types of cabling. Suitable cable managers can be used to manage the cables coming from all the devices. It is always recommended that heavier devices be placed at the bottom and lighter devices at the top. For example, a Cisco UCS B-Series chassis can be placed at the bottom and Fabric Interconnect at the top of the rack. The number of UCS or Nexus devices in a rack can vary based on the total power available for it.

The Cisco R-Series R42610 rack is certified for Cisco UCS devices and Nexus switches, which provides better reliability, space, and structural integrity to data centers.
