Ensure that inlet air enters at the front of the server and exits from the back.
Ensure that ventilation openings, such as cabinet doors, for both the inlet and exhaust of the server provide a minimum open area of 460 cm2 (71.3 in.2) each. This ventilation equates to a 60% open area perforation pattern across the front and rear area of the server. You must evaluate the impact of other open area characteristics that are more restrictive.
Allow a minimum of 5 mm (0.2 in.) clearance at the front of the system and 80 mm (3.1 in.) at the rear of the server when mounted. These clearance values are based on the inlet and exhaust impedance (available open area). These values also assume a uniform distribution of the open area across the inlet and exhaust areas. Use greater clearance values to improve cooling performance.
Note - The combination of inlet and exhaust restrictions such as cabinet doors, and the spacing of Oracle’s Sun SPARC Enterprise T5440 server from the doors can affect the cooling performance of the server. You must evaluate the effect of these criteria.
Take care to prevent recirculation of exhaust air within a rack or cabinet.
Manage cables to minimize interfering with the server exhaust vent.
