10 Site Planning Guide for Sun Blade 6000 and Sun Blade 6048 Modular Systems • February 2012
Airflow Requirements
The system uses forced air to draw in ambient air for cooling from the front of the
chassis, while heated air exits the rear of the chassis. The design of the system
provides two primary regions of airflow: The lower airstream cools the server
modules, and the upper airstream cools the power supplies, chassis monitoring
modules, Sun Blade 6000 network express modules, and PCIe ExpressModules.
The rear fan cage includes six rear fan modules, each module having two fans, for a
total of 12 fans. The fans draw cool air through the front of the server modules and
exhaust heated air through the back of the chassis. This results in a typical
measurement of approximately 600
CFM of total airflow.
The upper airstream provides forced air by using a combination of internal fans
within each power supply.
Follow these airflow guidelines:
■
Do not block the ventilation areas of the chassis.
■
Ensure that all cabling at the rear of the chassis does not block any exhaust air.
■
Ensure that front and rear cabinet doors are at least 60 percent perforated to
ensure minimal restriction of airflow. Removal of either or both doors will
improve the cooling capability of the system.
■
Front and rear clearance between the inside of the cabinet doors and the system
should allow a minimum of 0.2 inch (0.5 cm) at the front of the system and 3.1
inches (7.9 cm) at the rear of the system for proper airflow.
Clearance for Service and Aisle
Requirements
To enable installation and servicing of the system, including access to system cables,
follow these space restrictions.
Location Service Access Requirement
System extended from rack 3 feet (0.9 m) on both sides of the system to facilitate
installation
Front cold aisle 5 feet (1.5 m); required for rackmounting
