Chapter 2 Environmental and Electrical Specifications 2-9
2.3.2 Airflow and Heat Dissipation
Since the SPARC Enterprise M8000/M9000 Server is designed to be cooled by forced
air convection, sufficient airflow throughout the entire system must be generated. To
satisfy the requirements listed below, the installation space requirements listed in
Section 1.2.2, “System Installation (Space)” on page 1-12 must be observed.
Any other equipment installed around the system must not block any of the service
areas, or intake and exhaust air vents.
The SPARC Enterprise M8000 Server uses internal fans to generate a total airflow
of 94 cubic meters per minute (3320 cubic feet per minute [cfm]) under normal
operating conditions.
