14 Configuring and Monitoring a
Redundant Server System
PlantScape supports both dual networks and redundant servers, in any
combination. For example, you can configure:
• Station connections to redundant servers over dual networks
• Redundant connections between redundant servers (recommended)
The following figure shows a sample network architecture drawing for a fully
redundant system. A diagram like this is useful for checking the validity of your
configuration and for finding problems during configuration and testing. If any
node or network seems to be functioning incorrectly with respect to network
communications, checking its configuration against the network architecture
drawing is a quicker way to find any misconfiguration than just running
diagnostics.
Your diagram should show:
• All network-connected computers running PlantScape Server or Station
(generically called “nodes”)
• Single or dual network connected
• Network/subnetwork ID for each of the networks
• Name and IP address for each network interface card (NIC) connected
anywhere on either network
