Server Failover Configurations
17
Dual-Connected Configuration
The following diagram illustrates the failover cluster architecture for an Avid ISIS environment.
In this environment, each cluster node is “dual-connected” to the network switch: one network
interface is connected to the VLAN 10 subnet and the other is connected to the VLAN 20 subnet.
If one of the subnets fails, the virtual server remains online through the other subnet.
The following table describes what happens in the dual-connected configuration as a result of an
outage:
VLAN 20

Type of Outage Result
Hardware (CPU, network adapter,
memory, cable, power supply) fails
The cluster detects the outage and triggers failover to the remaining node.
The Interplay Engine is still accessible.
Left ISIS VLAN (VLAN10) fails The Interplay Engine is still accessible through the right network.
Right ISIS VLAN (VLAN 20) fails The Interplay Engine is still accessible through the left network.
