SUPERSERVER 2027TR-H71RF/H71FRF/H71QRF USER'S MANUAL
1-5 2U Twin 2 : System Notes
As a 2U Twin
2
confi guration, the 2027TR-H71RF/H71FRF/H71QRF 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 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 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 1620 Watt power supply is 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 2027TR-H71RF/H71FRF/H71QRF supports the use of twenty-four
SAS/SATA drives (six per serverboard). 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 six SAS/SATA drives to each serverboard. Consequently,
RAID setup is limited to a six-drive scheme (RAID cannot be spread across all
twenty-four drives). See the Drive Bay Installation/Removal section in Chapter 6
for the logical hard drive and node confi guration.
