FortiSwitch-5003 system

Base backplane communications

In a single chassis, more than one cluster can use the same base backplane interface for HA heartbeat communication. To separate heartbeat communication for multiple clusters on the same base backplane interface, configure a different HA group name and password for each cluster.

In a single chassis, you can also use the same base backplane interface for data and HA heartbeat communication. If you are operating multiple clusters and multiple data paths on the same base backplane interface you may experience some bandwidth limitations. To increase the amount of bandwidth available you can add a second FortiSwitch-5003 board and use both backplane interfaces for HA heartbeat and data communication.

If you have two FortiSwitch-5003 boards and two backplane interfaces available you can balance the traffic between the base backplane interfaces by how you configure your FortiGate-5000 board data interfaces and HA heartbeat interfaces. For example, if you have two busy FortiGate-5001SX clusters you might configure one cluster to use port9 for HA heartbeat traffic and the other to use port10. If you have a number of data paths that use the same base backplane interfaces you can change the configuration to distribute traffic between both base backplane interfaces.
