Clustering Benefits
VidyoGateway clustering enables you to scale your VidyoGateway capacity to hundreds of
simultaneous calls by deploying multiple VidyoGateways per VidyoPortal and per tenant. By
clustering, you are enabling the multiple VidyoGateways to balance both the H.323 and SIP load,
thereby increasing your call scalability.
When creating clusters, you need to assign Controller 1 to one of your VidyoGateways and
designate the other VidyoGateways as Controller 2 and/or Cluster Node. Any VidyoGateway can
be a Controller 1, Controller 2, or Cluster Node in your VidyoGateway cluster. The Active and
Standby Controller roles will be automatically assigned by the system to the two controllers
(Controller 1 and Controller 2).
The Active Controller automatically sends calls to the first available VidyoGateway in your cluster.
To assign the VidyoGateway Standalone, Controller 1, Controller 2, or Cluster Node, you use
VidyoGateway’s Cluster tab. For more information, see
Configuring Clusters
.
Note
The Active Controller automatically sends calls to the first available VidyoGateway in your
cluster.
When deploying a cluster of VidyoGateways, they all must reside on the same network and
on routable network in relation with the Legacy device. VidyoGateway clustering is not
supported in a NAT environment.
Cluster Configuration with a Legacy Gatekeeper Interface
After configuring your VidyoGateway cluster, see
Configuring Clusters
, you can then configure your
system to interface with a Legacy gatekeeper as shown in the following illustration.

Note: The Active Controller automatically load balances calls to
