2U Twin: System Notes
2
As a 2U Twin
confi guration, the SuperServer 2027TR-D70RF+ is a unique server
system. With two system boards incorporated into a single chassis acting as two
separate nodes, there are several points you should keep in mind.
Nodes
Each of the two 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
Dual 1280 Watt power supplies are used to provide the power for all four
serverboards. Each serverboard however, can be shut down independently of the
other with the power button on its own control panel.
SAS/SATA Backplane/Drives
As a system, the SuperServer 2027TR-D70RF+ supports the use of twenty-four (24)
2.5" SAS/SATA drives. A single SAS/SATA backplane works to apply system-based
control for power and fan speed functions, yet at the same time logically connects a
set of twelve SAS/SATA drives to each serverboard. See the Drive Bay Installation/
Removal section in Chapter 6 for the logical hard drive and node confi guration.
