B Server Blade Configuration Examples

This appendix contains illustrations and descriptions of fully cabled HP XC systems based on interconnect type and server blade height.

The connections are color-coded, so consider viewing the PDF file online or printing this appendix on a color printer to take advantage of the color coding.

B.1 Gigabit Ethernet Interconnect With Half-Height Server Blades

In Figure B-1, only the half-height server blades and the non-blade server nodes have connections to the external network. Because the two NICs of the half-height server blade are already in use, an Ethernet card was added to mezzanine bay 1 to allow for the external network connection on the server blade. An interconnect module was added to bay 3.

On the non-blade server nodes, PCI Ethernet NICs are used for the external network connection. Available ports vary based on hardware model. See the HP XC Hardware Preparation Guide for more information about port assignments.

B.2 InfiniBand Interconnect With Full-Height Server Blades

In the configuration shown in Figure B-2, connections to the external network were required only on the non-blade server nodes and the full-height server blades. On those server blades, NIC3 is used for the connection to the external network. A VLAN is used to separate the external network traffic from the administration network traffic on the switch in bay 1 to save the expense of an additional Ethernet interconnect module in bay 2.

On the non-blade server nodes, the built-in NICs were used for the external network connection. Available ports vary based on hardware model. See Chapter 3 (page 45) for more information about port assignments.
