Airflow Considerations

The Sun Fire V215 and V245 servers self-cool when operated in still air.
Ensure unobstructed airflow through the chassis.
Sun Fire V215 servers use internal fans that can achieve a total airflow of 30
cfm in normal operating conditions.
Sun Fire V245 servers use internal fans that can achieve a total airflow of 60
cfm in normal operating conditions.
Ensure that inlet air enters at the front of the server and exits from the back.
Ventilation openings for both the inlet and exhaust of the system should provide:
Sun Fire V215 server – a minimum open area of 85 cm
Sun Fire V245 server – a minimum open area of 170 cm
Allow a minimum of 88.9 mm (3.5 inches) clearance at the front and rear of the
server when mounted, unless an unobstructed airflow can be ensured.
