2U Twin: System Notes
As a 2U Twin confi guration, the 6026TT-HD/D6 series is a unique server system.
With two system boards incorporated into a single chassis acting as two separate
nodes, there are several points you should keep in mind.
Nodes
Each of the two 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.
Backplane/Drives
As a system, the 6026TT-HDx and 6026TT-D6x servers supports the use of twelve
SATA and SAS drives, respectively. 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 SATA drives to each serverboard. Consequently, RAID setup is limited
to a six-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.
