Heat Dissipation and Airflow Requirements
The maximum rate of heat released from a fully-configured SPARC M8-8 or SPARC M7-8 server is 35,500 BTUs/hr (37,455 kJ/hr). The maximum rate of heat released from a fully-configured SPARC M7-16 server is 77,800 BTUs/hr (82,084 kJ/hr). To cool the server properly, ensure that adequate airflow travels through the server.
The direction of the airflow is from the front to the back of the server. The approximate server airflow is:
SPARC M8-8 server:
-
Maximum: 860 CFM
-
Typical: 590 CFM
SPARC M7-8 server:
-
Maximum: 860 CFM
-
Typical: 590 CFM
SPARC M7-16 server:
-
Maximum: 2240 CFM
-
Typical: 1400 CFM
To ensure adequate airflow:
-
Allow a minimum clearance of 36 inches (914 mm) at the front and the rear of the server for ventilation.
-
If the server is not completely populated with components, cover the empty slots with filler panels.
-
Manage cables to minimize interference with the server exhaust.
 | Caution - When installing three SPARC M8-8 or SPARC M7-8 servers in the same rack, you must cover all empty rack slots using 3U metal filler panels. You must also use 3U metal filler panels when installing a combination of three of these servers in the same rack (for example, two SPARC M8-8 servers and one SPARC M7-8 server). Contact your Oracle Sales representative to order the correct 3U filler panel for Oracle racks (part number: 7326328). See Install Filler Panels for installation instructions. |
Note - There are no airflow requirements for the left and right sides or the top and bottom of the server.
