1-4 2U Twin: System Notes
As a 2U Twin confi guration, the 2026TT-HxRF 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.
System Power
The server has an additional 1400W power supply module (two total) for power
redundancy. If a power supply module fails the other backup module will keep the
system running until it can be replaced.
SAS/SATA Backplane/Drives
As a system, the 2026TT-HxRF supports the use of 24 SAS or SATA drives. 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 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 confi guration.
