Server redundancy
The Senstar Symphony Server supports server redundancy in server farms. If the primary Senstar Symphony Server stops responding, the camera and device processing moves to a redundant Senstar Symphony Server.
To use server redundancy you must have at least one primary Senstar Symphony Server and one redundant Senstar Symphony Server in a redundancy group. The primary Senstar Symphony Server actively performs camera and device processing. The redundant Senstar Symphony Server is active, but it does not have any cameras or devices associated with it. There must be at least one redundant server available in the server farm at all times.
- You can move the camera and device processing back to the primary Senstar Symphony Server automatically by enabling failback in the Senstar Symphony Server configuration interface.
- You can move the camera and device processing back to the primary Senstar Symphony Server manually by swapping servers in the Senstar Symphony Server configuration interface.
- You can use the primary Senstar Symphony Server as a redundant Senstar Symphony Server.
In a redundancy group, one Senstar Symphony Server is the master server. The master server performs the additional task of managing failover and failback operations. If the master server is unavailable, another Senstar Symphony Server in the redundancy group becomes the master server. You can manually select the master server by selecting the star icon beside the Senstar Symphony Server on the Servers page in the Senstar Symphony Server configuration interface.
