1-6 System Notes
The SSG-2028R-DN2R48L Super SBB was designed to function as a fully
redundant, fault-tolerant "cluster-in-a-box" system with hot-swappable nodes for all
active components.
Nodes
The SSG-2028R-DN2R48L features a dedicated B2B connection using an Intel
XL710 private LAN connecting the bottom server module with the top server
module. This connection is used for high speed data transfers between nodes for
High Availability/server fail-over. This fail-over capability is fully dependent on the
software/OS installed and how the chosen software uses the connection (Active-
Active or Active-Passive). The SSG-2028R-DN2R48L hardware is supplied without
a storage OS or fail-over software.
Equipped with 2000 Watt 80+ Titanium Level redundant power supplies and
redundant cooling fans, the SSG-2028R-DN2R48L offers fully redundant, high
availability while maintaining energy efficient operation.
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.
System Power
Dual 2000 Watt power supplies are used to provide the power for all serverboards.
Each serverboard however, can be shut down independently of the other with the
power button on its own control panel.
NVMe Backplane/Drives
As a system, the SuperStorageSystem SSG-2028R-DN2R48L supports the use of
forty (48) 2.5" NVMe drives. The NVMe backplane works to apply system-based
control for power and fan speed functions. See the Drive Bay Installation/Removal
section in Chapter 6 for the logical hard drive and node configuration.
