X6800 system architecture

2.2 Heat Dissipation

l

The system draws in air from the front of the chassis, delivers the cool air to the server
nodes, hard disks, processors, dual in-line memory modules (DIMMs), backplane, and
fan modules, and then discharges warm air through the rear of the chassis.

l

Two PSUs are installed in each side of the server chassis. Separated ventilation channels
are reserved to deliver the return air from the PSU fans for cooling.

l

The system fans implement cooling of the management boards and I/O boards on the fan
modules.

l

The high-pressure counter-rotating fans offer 10% higher air volume than common fans.
The refined air channels implement concentrated cooling of heat-sensitive devices. The
optimal distribution of temperature sensors covers all areas of high heat concentration
(server hotspots), facilitating accurate fan speed adjustment. The cellular design on the
panel offers a porosity of 66%, which is 10% higher than that of square holes. The fans
