In addition to the cluster interconnects and system administration network, each
cluster node should also have an interface on a public network. For the sake of
simplicity, the public network for each node is not shown in Figure 1 or Figure 2.

NOTE: The cluster console bundles the individual console lines
of the cluster hosts to be accessible from one machine for a
single point of administration
and node elimination tasks.

Another option is a similar configuration without the cluster console, as shown
in Figure 2. The main components are the same except the cluster console is
removed and an RCI connection is required.
The RCI is a special interface on PrimePower machines. RCI connections allow
machines to monitor each other's states and to shut each other down. If your
Solaris machine does not have an RCI connection, you will need to use a
different shutdown technology in your configuration.
