Description
In a failover cluster setup only one of the Ozeki NG SMS Gateway nodes operate at a time.
We destinguish the primary node (System "1") and the backup node (System "2").
The primary node serves all the clients at any give time, the backup node serves none.
The primary node is connected to all the sms service providers, the backup node is not
connected to any provider.
During normal operation the primary node is "On-line" the backup node is "Off-line".
In this setup the primary and the backup node usually share a common storage facility,
called shared disk or quorum disk. This shared storage option allows the two
system to be synchronized.
Normal operation
Failover
In case the primary node goes down because of a hardware failure, the backup node
is automatically activated. It picks up the configuration and the message queues from
the shared disk, and continues to provide the service where the primar node left off.
Please note, that this configuration requires persistent message queues.
The benefits of this configuration over the Live cluster setup 1 and
Live cluster setup 2 lies in its simplicity. The configuration
is easy, because only the primary node needs to be configured. The shared storage facility provides
a way for the two nodes to share the configuration.
