Because the two Cluster Internal adapters are connected, they are automatically assigned an IPv4
link-local address from the address block 169.254.0.0/16. This network will be used in a later
step for configuration of the second node from the first node, and it also is used as a private cluster
heartbeat network when the cluster is deployed. HP recommends that you do not make changes
to the configuration of the Cluster Internal network adapter.
The remaining network adapters are intended for use in your network infrastructure. Each adapter
is labeled according to a suggested use (for example, 1 GbE Public 1), but you may rename the
adapters in later configuration steps and use them in a way best suited to your environment.
In the network infrastructure that connects the cluster nodes, avoid having single points of failure.
One way to do this is to have at least two distinct networks. The HP X5000 G2 already provides
one network between the nodes—the Cluster Internal network. You must add at least one more
network. As you connect the HP X5000 G2 to your network infrastructure, consider the following
requirements:
• Since deploying the cluster requires that both servers be joined to an Active Directory domain,
you must have a route to the domain controller from each server on the storage system.
• Servers in a cluster must use DNS for name resolution, so you must have a route to a DNS
server from each server on the storage system.
• If you are adding more than one adapter per server to your network infrastructure, each
adapter should be on a different subnet.
Figure 7 (page 14) shows two possibilities for adding network cables for an additional network.
