Type: White Paper
Rating: (0)

Overview: Enterprise Survivable Servers (ESS) is a contribution which takes an existing Avaya Communication Manager (CM) system to a higher level of availability and survivability. ESS achieves this by allowing media servers to be used as alternate controllers within a system by leveraging IP control of port network gateways and being completely autonomous of the main servers both functionally and geographically. ESS protects the communication system against a disastrous main server failure and at the same time, presents service to port network gateways that have been fragmented away from their present controlling entity.
