Airflow Considerations

Ensure unobstructed airflow through the chassis.
■
Ensure that inlet air enters at the front of the server and exits from the back.
■
Ensure that the server ventilation openings used for intake and outflow of air
■
provide an open area that is at least 60% of the open area perforations across the
front and rear of the server. This 60% minimum open area equates to the following
dimensions, depending on the server model:
Minimum Open Area
SPARC Enterprise T5120 Server
SPARC Enterprise T5220 Server
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 preceding inlet and exhaust impedance (available open area) and assume a
uniform distribution of the open area across the inlet and exhaust areas. Clearance
values greater than these are recommended for improved 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 and should be evaluated by the user.
Take care to prevent recirculation of exhaust air within a rack or cabinet.
■
Manage cables to minimize interfering with the server exhaust vent.
