Understanding The Clustering Procedure - Vidyo VidyoGateway Administrator's Manual

5. Configuring Your System

Each VidyoGateway server in your cluster must all be physically located in the same data
center. The clustering functionality does not support VidyoGateways located in separate data
centers.

Each VidyoGateway server in your cluster must have a properly configured hostname, IP
address, and shared IP address. The information for each of these fields is required for the
Cluster to work. The shared IP address is the one that will be dialed by incoming calls. For
more information, see
Cluster Node.
 VidyoGateway high availability relies on the address resolution protocol (ARP) request to
determine whether the floating IP address is up. If it is not up, the VidyoGateway (active or
standby) takes possession of the shared IP address.
Cluster Configuration
The
Standalone, Controller 1, Controller 2, or Cluster Node VidyoGateway. You can also provide
additional data for each component depending on the machine's VidyoGateway cluster role. A
specific email address can be set on the Controller nodes to send an automatic failover notification
for protective measures.
When the Active Controller is configured properly, the following takes place in the event of a failure:
1. Existing calls fail as the Standby Controller takes the IP address of the Active Controller that
went down.
2. The new Active Controller sends out the email notification alerting users of the system
failure.
Note The original Active Controller must be repaired with its original hardware and software intact
in order to be returned to your system setup.

Understanding the Clustering Procedure

Perform the steps from the following sections to create your VidyoGateway Cluster.
To create a VidyoGateway cluster:
1. Make sure you've assigned a hostname to Controller 1, and then reboot your machine.
For more information, see
2. Access Controller 2 and assign a different hostname to it, and then reboot your machine.
For more information, see
3. Perform the cluster configuration settings on Controller 1, reboot, and then reboot your
machine.
