Cable Management Plate; Example Infiniband Cable Routing For Cpe With Rack-Mountable Server Configurations - HP Cluster Platform Express v2010 Overview

Note:
The HP BLc 4X DDR InfiniBand Gen 2 Switch is not currently supported in HP BladeSystem
c3000 enclosures. For more information, contact your HP representative.
Figure 1-9 provides and example of the InfiniBand cable management in CPE rack-mountable
server configurations. Note the InfiniBand cables running from a Voltaire ISR 9024D, 24-port
interconnect to each rack-mounted server in the rack. Also, note the cable management brackets
used to provide the necessary support for the InfiniBand cables during shipment. It is not
necessary to remove the cable management brackets after the system is installed. HP recommends
leaving these brackets installed to maintain good connections, provide strain relief for the cables,
and maintain the minimum bend radius for the InfiniBand cables.
A Voltaire 24-port interconnect can be used in CPE BladeSystem configurations for fabric
management. Configuration rules can vary depending on the choice of operating system and
also customer preference. Consult with your HP representative if you have any questions about
specific CPE configuration rules.

The following list describes the callouts in
1. Direction of view, towards the rear of the rack.
2. Rear right rack column.
3. Cable bundles running to the interconnect from the upper part of the rack.
4. Support brackets. Cables from servers adjacent to the interconnect are not routed along the

cable management plate (3).

Note:
It might be necessary to remove the cable management brackets to service components installed
in the rack. To remove these brackets, reverse the installation procedures described in the HP
Cluster Platform c-Class Cable Management Bracket Installation Guide and the HP Cluster Platform
24-Node Cable Management Kit Installation Guide.
