Symphony 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, Symphony
designates another server as the master server.
Server redundancy works within redundancy groups.
