confi guration, the SuperServer 6026TT-HT(R)F/HIBX(R)F/HIBQ(R)F
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
6026TT-HTF/HIBXF/HIBQF: a single 1400 Watt power supply is 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.
6026TT-HTRF/HIBXRF/HIBQRF: this version of the server has an additional
1400 Watt 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.
SATA Backplane/Drives
As a system, the SuperServer 6026TT-HT(R)F/HIBX(R)F/HIBQ(R)F supports the
use of twelve SATA drives. A single SATA backplane works to apply system-based
control for power and fan speed functions, yet at the same time logically connects a
set of three SATA drives to each serverboard. Consequently, RAID setup is limited
to a three-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.
