A+ SERVER 2022TC-BIBQRF/BTRF USER'S MANUAL
1-5
2U Twin
As a 2U Twin
configuration, the 2022TC-BIBQRF/BTRF is a unique server system.
2
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
By default, the 2022TC-BIBQRF/BTRF comes with two power supply modules for
redundancy A single 1400 Watts power supply can 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.
Note: Depending on the input power and certain workloads, configuration power
supply redundancy may not always be available.
SATA Backplane/Drives
As a system, the 2022TC-BIBQRF/BTRF supports the use of twelve SATA drives.
A single SATA backplane works to apply system-based control for power and fan
speed functions, yet at the same time logically connects a set of three SATA drives
to each serverboard. Consequently, RAID setup is limited to a three-drive scheme
(RAID cannot be spread across all twelve drives). See the Drive Bay Installation/
Removal section in Chapter 6 for the logical hard drive and node configuration.
