How does fail over works

Instruction
Failover Agent is a software to enable a spare recording server (the failover server) to take over the recording work once the regular recording server become unavailable.

Note 1: Support IP+ and Video Encoder (no capture card)
Note 2: If there are more than 1 server crashed Failover server will take over the higher priorty server to make sure not to loss the important recording.

For example,
NUUO Failover Agent Scenario
3 recording servers(Mainconsole) and1 failover server.(as below picture)
Mainconsole a (32 ch): Priority 2
Mainconsole b (32 ch): Priority 3
Mainconsole c (32 ch): Priority 1

1. Failover will continuously detecting the recording servers.


2. Once the failover detect the server crashed, for example Mainconsole a, then it take over the jobs of Mainconsole a to do the recording.

3. Regaring the priority, if the priority 1 Mainconsole c is crashed at the same time, the Failover will give up the lower priority server(Mainconsole a) and take over the higher priority server(Mainconsole c)



1 Failover server can support up to 8 Mainconsole servers but only can backup one server at the same time.
