From OVNM 4.2 release, the single source feed (SSF) Elink will run in mixed mode. This means that OVNM is
configured to broadcast messages to multiple servers AND to Primary/Backup server. OVNM can support one
Primary server, one Backup server and unlimited broadcast type servers.
Figure 6-3 Mixed Mode
If there are a number of adapters or clients, only one of them can be configured as Primary or Backup server.
Others can be configured as broadcast servers. If the Primary server goes down, the Backup server will receive
events. The clients configured as Broadcast servers will receive events continuously.
