The Cluster Network

Perceus takes a typical cluster provisioning approach to networking. This being a master node to slave node relationship. This relationship is networked by one or more private networks that is used for DHCP, provisioning and administration of the nodes (among other non-Perceus related things).

Simplest Form

The master node is connected to 2 networks. One being publicly accessible, the other being private and shared specifically only to the nodes and devices that are accessible to the cluster itself (e.g. a network attached storage device).

Literally the master node is connected to the public LAN/WAN on one port, and the next port is connected to a standalone switch or set of switches to which all nodes are plugged into.

Larger scale solution

Starting with the simplest form, you can have the Perceus master(s) and all nodes on a single private network with a dedicated firewall/gateway bridging this network to the LAN/WAN with either some gateway login system bridging the gap, or doing a port forward/masquerade from the firewall to a login system on the private network.

Multiple Networks

Once the cluster network has been correctly configured, it is possible to multi-home the nodes (two or more network controllers in each node connected to additional networks).

A typical example here would be if each of the nodes must have real publicly accessible IP addresses.
