System Redundancy Overview
A redundant RealPresence Resource Manager system configuration offers
higher reliability and greater call success by ensuring that a RealPresence
Resource Manager system is always available.
A redundant RealPresence Resource Manager system configuration requires
two RealPresence Resource Manager 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 external access and endpoint
registration.
