Ventilation Guidelines

The Oracle Server X5-4 has been designed to function while installed in a natural convection airflow. The following environmental specifications must be met:

Ensure that server air intake is at the front of the rack, and the air outlet is at the back of the rack.

Rack-mount servers, including the Oracle Server X5-4, draw cool air in through the front of the server and exhaust warm air out the back of the server.
Ensure that there is adequate airflow through the server.
- Allow a minimum clearance of 1,232 mm (48.5 inches) at the front of the server, and 914 mm (36 inches) at the back of the server.
  
  The clearance provides for airflow and ventilation space at the air intake and outlet areas.
- Ensure that ventilation openings such as cabinet doors, for both the inlet and exhaust of the server are not obstructed.
  
  For example, Oracle's Sun Rack II is optimized for cooling. Both the front and back doors have 80 percent perforations that provide a high level of airflow. Ensure that these perforations are not blocked.
- Ensure that the front and back clearance of the server allows a minimum of 2.5 mm (1 inch) at the front of the server and 80 mm (3.15 inch) at the back of the server when mounted.
  
  These clearance values are based on the inlet and exhaust impedance (available open area) stated here and assume a uniform distribution of the open area across the inlet and exhaust areas. These values also improve cooling performance.
  
  Note - The combination of inlet and exhaust restrictions, such as cabinet doors and the spacing of the server from the doors, can affect the cooling performance of the server. You must evaluate these restrictions. Server placement is particularly important in high-temperature environments.
- Ensure unobstructed airflow through the server chassis internals.
  
  The server uses internal blowers that can achieve a total airflow of 100 CFM. Airflow through the server must be consistent and direct. Chaotic airflow inside the server can be created by obstructions from dust and debris in the intake and outlet vents, misaligned components, such as air baffles and dividers, and improperly dressed cables, both inside and outside of the server.
Ensure that air temperature rise through the server is no greater than 68°F (20°C).
Take care to prevent recirculation of exhaust air within a rack or cabinet.
Manage cables within the rack to minimize interference with the server exhaust vent.
