The three most common network environments that require Exinda clustering are:
- The environment is critical and failover is necessary. Typically, one network link is active and the other is passive. The Exinda Appliance on the passive link clusters with the active Exinda Appliance so it has all the required data and configuration settings in case the active link fails.
- The environment has dual paths with active links into one or more ISPs. In this case, the Exinda Appliances need to be clustered so each appliance exchanges all traffic with the others.
- The environment is load balanced with traffic distributed across several servers. In this case, an Exinda Appliance is installed in front of each load balanced server and all other Exinda Appliances cluster so they each have the same configuration and network traffic can be reported on in aggregate.
