3.2 Ethernet Port Connections on the Head Node

Table 3-2 lists the Ethernet port connections on the head node based on the type of interconnect in use.

Use this information to determine the appropriate connections for the external network connection on the

head node.

IMPORTANT: The Ethernet port connections listed in Table 3-2 do not apply to HP XC systems with HP

server blades and enclosures.

For more information, see the HP XC Systems With HP Server Blades and Enclosures HowTo, which is available

at the following Web site:

• Physical onboard Port #1 is always the connection to the

Administration Network.

• Physical onboard Port #2 is available for an external

connection if needed (except if the port is 10/100, then it is

unused).

• Add-on NIC card #1 is available for an external connection

if Port #2 is 10/100.

• Physical onboard Port #1 is always the connection to the

Administration Network.

• Physical onboard Port #2 is the connection to the interconnect.

• Add-on NIC card #1 is available as an external connection.

3.3 General Hardware Preparations for All Cluster Platforms

Make the following hardware preparations on all cluster platform types if you have not already done so:

1. The connection of nodes to ProCurve switch ports is important for the automatic discovery process.

Ensure that all nodes are connected as described in “Making Node and Switch Connections” (page 19).

2. Ensure that switches are configured to obtain IP addresses using DHCP. For more information on

how to do this, see the documents that came with the ProCurve hardware. ProCurve documents are

also available at the following Web page:

http://www.hp.com/go/hpprocurve

3. Ensure that any nodes connected to a Lustre® file system server are on their own Gigabit Ethernet

switch.
