1-6 Fat Twin: System Notes
As a FatTwin confi guration, the FatTwin F628G3-FT+/FTPT+ 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 serverboards act as a separate node in the system. As independant
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 rear of the chassis.
The nodes are connected to the server backplane by means of an adapter card.
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
Four 2000 Watt power supplies are used to provide the power for all serverboards.
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 F628G3-FT+/FTPT+ supports the use of eight (8) 3.5"
Hot-swap SATA drives. Each of the four backplanes in the system works to apply
system-based control for power and fan speed functions, yet at the same time
logically connects a set of two (2) hot-swap SATA drives to each backplane/
serverboard. Consequently, RAID setup is limited to a two drive scheme (RAID
cannot be spread across all drives). See Chapter 6 for the logical hard drive and
node confi guration.
