2U Twin: System Notes
As a 2U Twin confi guration, the 2026TT-DLxRF 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.
SAS/SATA Backplane/Drives
As a system, the 2026TT-DLxRF 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 12 drives to each
serverboard..
