1.6.10The Voltaire InfiniBand interconnect
Figure 1-23 shows how ProLiant DL360 servers are connected to the Voltaire InfiniBand interconnect.
Figure 1-23 shows a system using ProLiant DL360 servers; the connections in a system using ProLiant DL380
servers would be similar (subject to the rules defined in Section 2.4.1).
Figure 1-23 Voltaire InfiniBand interconnect
The Voltaire Host Channel Adapter (HCA) is plugged into the first PCI slot on each ProLiant DL360 server.
The HCA adapter has 2 ports; the InfiniBand interconnect connection must be plugged into port 1 (labelled
P1) on the adapter. Dual port mode is not supported. It is of no consequence to the HP SFS system which
ports on the Voltaire switch are used for the connections to the servers. Similarly, no specific configuration
is required on the switch. You can change InfiniBand port assignments at any time; however, the file systems
must be stopped when you do so. For a detailed description of your Voltaire switch, see the documentation
specific to the switch.
CAUTION: InfiniBand interconnect cables are very fragile and should never be folded or stepped on.
