SUPERSERVER 2028TR-HTR/HTFR/H72R/H72FR User's Manual
1-6
2U Twin
As a 2U Twin
configuration, the SuperServer 2028TR-HTR/HTFR/H72R/H72FR is
2
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 1600 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
The SuperServer 2028TR-HTR/HTFR/H72R/H72FR supports the use of 24 hard
drives (SATA). A single backplane works to apply system-based control for power
and fan speed functions and logically connects a set of six hard drives to each
serverboard/node. 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.
Adapter Cards
Besides the serverboard, the four servers are differentiated by the type of adapter
card installed. The table below lists the differences between the four servers.
