HP XC System Software 3.2.1 manual Ethernet PCI Cards

server blades do not have three NICs, and therefore, half-height server blades are not included in this example

Because NIC1 and NIC3 on a full-height server blade are connected to interconnect bay 1, you must use VLANs on the switch in that bay to separate the external network from the administration network.

Also, in this example, PCI Ethernet cards are used in the non-blade server nodes. If the hardware configuration contains non-blade server nodes, see Chapter 4 (page 59) for information on which port to use for the external network.

2.6.2 Configuring the External Network: Option 2

Figure 2-9 (page 43) assumes that NIC1 and NIC2 are already in use for the administration and interconnect networks. This situation requires a third NIC for the external network, but unlike Figure 2-8 (page 42), this hardware configuration includes half-height server blades. Therefore, to make another Ethernet NIC available, you must add an Ethernet card to mezzanine bay 1 on each server blade that requires an external connection. You must also install an Ethernet interconnect module in interconnect bay 3 for these cards.

In addition, PCI Ethernet Cards are used in the non-blade server nodes. If the hardware configuration contains non-blade server nodes, seeChapter 4 (page 59) for information on which port to use for the external network.
