Chapter 3 Environmental and Electrical Specifications 3-9
3.3.2 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 1-13 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.
