1.3 FatTwin: System Nodes
As a FatTwin configuration, the FatTwin F619H6-FT is a unique server system. With four
system boards incorporated into a single chassis acting as four separate nodes, there are
several points you should keep in mind.
Nodes
Each of the four motherboards act as a separate node in the system. As independent nodes,
each may be powered off and on without affecting the others. In addition, each node is a
hot-swappable unit that may be removed from the front of the chassis.
Note:
A guide pin is located between the upper and lower nodes on the inner chassis wall.
This guide pin also acts as a “stop” when a node is fully installed. If too much force is used
when inserting a node this pin may break off. Take care to slowly slide a node in until you
hear the “click” of the locking tab seating itself.
System Power
Two high-efficiency 96%+ Titanium Level 2000 Watt power supplies are used to provide the
power for all motherboards. Each serverboard however, can be shut down independently of
the other with the power button on its own control panel.
SATA Backplane/Drives
As a system, the FatTwin F619H6-FT supports the use of up to 48 SAS2/SAS3/SATA3 drives.
Each of the backplanes in the system logically connects the internal fixed drives to each node's
backplane/serverboard. See Chapter 3 for the logical hard drive and node configuration.
