Server redundancy

VMS China supports server redundancy in server farms. If a VMS China Server stops responding, the camera and device processing moves to another VMS China Server.

A primary servers actively performs camera and device processing. When failover occurs, the primary server becomes a redundant server.

A redundant server does perform camera and device processing. There must be at least one redundant server available in the server farm at all times. When failover occurs, the redundant server becomes the primary server.

In addition, one server in the server farm is the master server. The master server performs the additional task of managing failover actions. If the master server is unavailable, VMS China designates another server as the master server.

Server redundancy works within redundancy groups.
