An Ethernet cluster interconnect uses the embedded NIC in each server
connected by one Ethernet crossover cable as shown in Figure 1-2.

LAN Connection
Clusters using Ethernet interconnect require an NC3123 NIC installed into
slot 1 of each node before cluster software installation so that the cluster can
access a public network. These NICs must be on a different subnet from the
embedded Ethernet cluster interconnect. Multiple public network controllers
can be installed after cluster installation is complete. For a list of certified
NICs, see the Compaq High Availability website at
http://www.compaq.com/highavailability
Clusters that use ServerNet I interconnect access the public network using the
embedded NIC. Each server must be connected to the same network.
