Always provide adequate space in front of and behind the rack to allow for proper ventilation of rackmounted servers. Do not obstruct the front or back of the rack with equipment or objects that might prevent air from flowing through the rack. Rackmountable servers and equipment, including the Oracle Server X7-8, draw cool air through the front of the rack and release warm air out the back of the rack. There is no airflow requirement for the left and right sides due to front-to-back cooling.
If the rack is not completely filled with components, cover the empty sections with filler panels. Gaps between components can adversely affect airflow and cooling in the rack.
Oracle Server X7-8 functions while installed in a natural convection airflow. Follow these environmental specifications for optimal ventilation:
Ensure that air intake is at the front of the system, and the air outlet is at the back. Take care to prevent recirculation of exhaust air in a rack or cabinet.
Allow minimum clearance of 123.2 cm (48.5 inches) in the front of the system, and 91.4 cm (36 inches) in the back.
Ensure unobstructed airflow through the chassis. The server uses internal fans that can achieve a total airflow of 100 CFM within the specified range of operating conditions.
Ensure that ventilation openings such as cabinet doors, for both the inlet and exhaust of the server, are unobstructed. For example, the Oracle's cabinets are optimized for cooling. Both the front and back doors have perforations that provide a high level of airflow through the rack.
Ensure that front and back clearances between the cabinet doors is a minimum of 2.5 cm (1 inch) at the front of the server and 8 cm (3.15 inches) at the back of the server when mounted. These clearance values are based on the inlet and exhaust impedance (available open area) and assume a uniform distribution of the open area across the inlet and exhaust areas, which improves cooling performance.
Manage cables to minimize interference with the server exhaust vent.
