+### Network Topology
|
|
|
+Possible network configurations include:
|
|
|
* A flat topology where all nodes are connected to a switch which includes an uplink to the internet. This requires multiple externally-facing IP addresses
|
|
|
-* A hierarchical topology where compute nodes are connected to a common switch, but the master node contains a second network connection which is connected to the internet. All outbound/inbound traffic would be routed through the master node. This requires setting up firewall rules for IP masquerade, see (https://www.server-world.info/en/note?os=CentOS_7&p=firewalld&f=2) for an example.

|
+The recommended setup is to assign IP addresses to individual servers. This can be done manually by logging onto each node, or via DHCP. In addition, hostnames should be assigned
