Chapter 1: Introduction

1-5 2U Twin

: System Notes

As a 2U Twin

conﬁ guration, the 2022TC-BIBQRF/BTRF 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

A single 1400W 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. As an option, you may add an additional

1400W power supply module for power redundancy.

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 conﬁ guration.
