Cisco StadiumVision Director Server Redundancy
Cisco StadiumVision Director supports an environment of two servers that run the Cisco StadiumVision Director software, where one of the servers operates as the primary active server, and the other server operates as a secondary backup server. If a failure occurs, you can configure the backup server to become the active server, but the failover process is not automatic.

Figure 3 shows the architecture of Cisco StadiumVision Director server redundancy under normal network conditions and operation. The primary and secondary servers are addressed as independent hosts with two different IP addresses on the same subnet in the Cisco Connected Stadium network.
While the secondary server is still connected to the network, notice that communication and control only occurs between the primary Cisco StadiumVision Director server and the rest of the network, including the Digital Media Players (DMPs).
The secondary server is only connected to the network to be made available as a backup to the primary should a failure occur. In addition, the secondary server can (and should) be configured to be backed up with data from the primary server on a scheduled basis so that it can be ready as a warm standby.

Figure 4 shows the redundancy environment when connectivity from the primary Cisco StadiumVision Director server fails. When the primary server fails, a manual process must take place to restore the secondary server from a backup, shut down the primary server, and activate the secondary server as the primary.

Notice that the secondary server must be reconfigured to use the same IP address the original primary server. In this example, the secondary server IP address is changed to 10.0.0.1 (from 10.0.0.2) to match the primary server address. When the process is complete, communication and control only occurs between the newly activated secondary server and the rest of the network.
Note The word “failover” does not mean automatic activation of a secondary server. The failover process is manual with the secondary server acting as a warm standby.
