•Discontinue Redundancy on a Polycom CMA 5000 System Configuration

Polycom CMA 5000 System Redundancy Overview

A redundant CMA system configuration offers higher reliability and greater call success by ensuring that a CMA system server is always available.

A redundant CMA system configuration requires two CMA system servers and three IP addresses in the same subnet on the same network—one physical IP address for each of the servers and one virtual IP address dedicated to endpoint registration.

How Redundancy Works

Terminology is very important in understanding how redundancy works.

In a redundant configuration, one server is licensed as the primary server and the other server is licensed as the redundant server. The primary server is always the primary server and the redundant server is always the redundant server.

In a redundant configuration, there is only one active server. The active server is the server managing the system. It is the server running all of the CMA system services. In a normal operational state, the active server is the primary server. In a failover state, the active server is the redundant server.
