INITIAL CONFIGURATION

This chapter provides an overview of how to configure Intelligent Mirroring on a Primary and Secondary server for the V7300 Voice Applications Suite.

Intelligent Mirroring is the mirroring of application data on two independently running servers. The mirrored application data is composed of table data and message component files.

Overview When you configure two servers for Intelligent Mirroring:

■ One of the servers operates in the active state

■ The other operates in standby state

At any one time, either the Primary or the Secondary server can be in the active state.

Hardware Prerequisites

You can install the Primary and Secondary servers on the same network or, for added reliability, you can connect each of them to an A and a B network (see described in this guide.

Before you begin to install Intelligent Mirroring on the Primary and Secondary servers, verify that you have the equipment and information outlined in the next two sections.

The Primary and Secondary Intelligent Mirroring servers run on the same hardware platforms that run the messaging system software.

3Com recommends that you connect each server to two different subnetworks for added reliability. To make these connections, each server requires two network interface cards, for a total of four cards.
