Server Failover Configurations

There are two supported configurations for integrating a failover cluster into an existing network:

• A cluster in an Avid ISIS environment that is integrated into the intranet through two layer-3

switches (VLAN 30 in Zone 3). This “redundant-switch” configuration protects against both

hardware and network outages and thus provides a higher level of protection than the

dual-connected configuration.

• A cluster in an Avid ISIS environment that is integrated into the intranet through two public

networks (VLAN 10 and VLAN 20 in Zone 1). This “dual-connected” configuration

protects against hardware outages and network outages. If one network fails, the cluster

application stays on line and can be reached over the other network.

Redundant-Switch Configuration

The following diagram illustrates the failover cluster architecture for an Avid ISIS environment

that uses two layer-3 switches. These switches are configured for failover protection through

either HSRP (Hot Standby Router Protocol) or VRRP (Virtual Router Redundancy Protocol).

The cluster nodes are connected to two subnets (VLAN 30), each on a different switch. If one of

the VLAN 30 networks fails, the virtual server remains online through the other VLAN 30

network and switch.

This guide does not describe how to configure redundant switches for an Avid ISIS media

network. Configuration information is included in the ISIS Qualified Switch Reference Guide,

which is available for download from the Avid Customer Support Knowledge Base at
