HA Configuration

If the load balancer you selected is in a high availability (HA) configuration, the element in the farm view area displays an HA.

To enable device failover or high availability, configure a standby-active pair of load balancer devices. You may add and remove virtual interfaces from within the Configure Server dialog box. See How To Configure the Load Balancer and How To Configure Virtual Interfaces for procedural information.
