Ventilation Guidelines

The Oracle Server X6-2 has been designed to function while installed in a natural convection airflow. The following requirements must be followed to meet the environmental specification:

  • Ensure that air intake is at the front of the system, and the air outlet is at the rear of the system. Take care to prevent recirculation of exhaust air within a rack or cabinet.

  • Allow a minimum clearance of 123.2 cm (48.5 inches) at the front of the system, and 91.4 cm (36 inches) at the rear of the system for ventilation.

  • Ensure unobstructed airflow through the chassis. The server uses internal fans that can achieve a total airflow of 100 CFM over the specified range of operating conditions.

  • 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 has been optimized for cooling. Both the front and rear doors have 80 percent perforations that provide a high level of airflow through the rack.

  • Ensure that front and rear clearance of the server with respect to cabinet doors is at minimum of 1 inch (2.5 mm) at the front of the server and 3.15 inches (80 mm) at the rear of the server when mounted. These clearance values are based on the inlet and exhaust impedance (available open area) stated above 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 for high-temperature environments.
  • Manage cables to minimize interference with the server exhaust vent.
