Typical heat dissipation and power consumption metrics for a Sun Fire X4100 M2 or X4200 M2 server equipped with 2 AMD Opteron
Series 2200 processors, 4 GB RAM (4 x 1 GB), on 73 GB SAS HDD and 2 Power Supplies are as follows:
• Max Power Consumption: 351 W
• Heat Dissipation: 1198 BTU/hr
• Tons of Air Conditioning: 0.1
• Heat Dissipation: 1198 BTU/hr
• Tons of Air Conditioning: 0.1
Note: Power consumption metrics can be calculated using the online Power Calculator for different configurations of the Sun Fire
X4100 M2 (http://www.sun.com/x4100M2/) and Sun Fire X4200 M2 (http://www.sun.com/x4200M2/).
Cooling
The chassis of the Sun Fire X4100 M2 and X4200 M2 servers are segregated by an air divider into two distinct chambers: the mother-
board/PCI and fan chamber and the Power Supply Unit (PSU) and storage chamber. Both areas are front-to-back air cooled. The PSU
and storage chamber is cooled by individual fans on the back of each power supply. Air is drawn through the front of the server by
these rear-located fans. The motherboard/PCI and fan chamber is cooled by redundant rows of fans mounted in front of the server
behind the bezel.
