High Availability Server Configuration
Avaya Messaging High Availability provides redundancy for the voice servers, limiting downtime in the event of hardware failures. Up to 10 servers are linked together to provide load balancing for high traffic sites, and failover support when one or more machines go down.
Due to the nature of High Availability systems, additional steps are required during configuration to ensure the proper operation of some features of Messaging.
Please use this chapter as a guide when you wish to configure your HA system.
