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 2000 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.
Hard Drive Backplane/Drives
As a system, the SuperServer 2028TP-HC0R/HC0TR/HC0FR supports the use of
24 hard drives (SAS or SATA). A single backplane works to apply system-based
control for power and fan speed functions, yet at the same time logically connects
a set of six hard drives to each serverboard. Consequently, RAID setup is limited
to a six-drive scheme (RAID cannot be spread across all 24 drives). See the Drive
Bay Installation/Removal section in Chapter 6 for the logical hard drive and node
configuration.
