management network, the cluster host network, the |OAM| network, and other
optional networks for external network connectivity.
.. note::
If you have a small number of nodes, smaller IP subnets / address
ranges should be used to preserve IP addresses that make the network
more manageable. When planning the system architecture an (optional) PXE boot,
management and cluster-host address is required for each node.
PXE Boot network is not "required" in all scenarios; in some scenarios
(e.g. IPv4 and non-vlan-tagged management networks), the management network
can be used for PXE booting.
The internal management network is required by all deployment configurations
for internal communication.
