Sun expansion cabinet or other EIA-compliant industry-standard rack enclosure
that meets the requirements listed in the table below. You need a Sun
rackmounting kit for each server that you will rackmount.

The rack must firmly support the weight of a Sun Enterprise 220R
server (75 lbs, 34 kg), plus the weight of the rackmounting
hardware, plus the weight of any other installed devices.
Each server requires four rack units (7 inches, 17.78 cm) of
vertical space for rack installation. A 72-inch (183-cm) cabinet
can hold up to nine servers.
The system requires 113 cfm at 40
This air-flow rate corresponds to 328 lb/hr at any
altitude and to 78 cfm at 40
For proper ventilation, each system in the rack enclosure requires
28 square inches (181 square cm) of unrestricted airflow into the
front of the system, and 23 square inches (148 square cm) of
unrestricted exhaust port at the back of the system. Maintain a
minimum 1.5 inches (3.8 cm) clearance between the system and
any front or back doors.
