The callout in these figures enumerates the following:

1.Port 50 is the link to the Root Console Switch.

Allocate the ports on this switch for maximum performance, as follows:

•Ports 1–10, 13–22, 25–34, 37–44 are used for the console ports of individual nodes (up to 38 nodes).

•Ports 11, 12, 23, 24, 35, 36, 45–49 are unused

3.4Interconnect Connections

The high-speed interconnect connects every node in the HP XC system. Each node can have an interconnect card installed in the highest speed PCI slot. Check the hardware documentation to determine which slot this is.

The interconnect switch console port (or monitoring line card) also connects to the Root Administration Switch either directly or indirectly, as described in “Root Administration Switch” (page 50).

You must determine the absolute maximum number of nodes that could possibly be used with the interconnect hardware that you have. This maximum number of ports on the interconnect switch or switches (max-node) affects the naming of the nodes in the system. The documentation that came with the interconnect hardware can help you find this number.

NOTE: You can choose a number smaller than the absolute maximum number of interconnect ports for max-node, but you can not expand the system to a size larger than this number in the future without completely rediscovering the system, thereby renumbering all nodes in the system.

This restriction does not apply to hardware configurations that contain HP server blades and enclosures.

Specific considerations for connections to the interconnect based on interconnect type are discussed in the following sections:

•“QsNet Interconnect Connections” (page 57)

•“Gigabit Ethernet Interconnect Connections” (page 57)

•“Administration Network Interconnect Connections” (page 57)

•“Myrinet Interconnect Connections” (page 58)

•“InfiniBand Interconnect Connections” (page 58)
