In a failover configuration, we can see to different IPs: one for Corporate and another for Acquisition. What are the differences between these two?

The acquisition network is typically used by DataMiner to synchronize its files with the passive agent, while the corporate network can be used for detection of automatic switching purposes (typically referred to as heartbeats). Having 2 networks also adds a second layer of redundancy in case one of the networks goes down. For more information see Failover preferred configuration

Jens, from the Preferred configuration help file included at the bottom:
1) can you expand on what exactly what the statement on “respecting the order of connection” means and why?
2) Is the NIC order actually associated with specific functions in DM. I would think the DM internal processing would in the end only care about IP address irregardless of what order the nics are in or if they are logically considered Corporate or Acquisition, a network socket connection does not care about which nic the destination IP address is associated with does it?
Thanks

Each of the two DMAs should have two network cards, connected to two different networks.
Make sure to respect the order of the connections in the Network Connections list.
•The first connection in the list represents the corporate network, which is used for heartbeats and synchronization.
•The second connection represents the acquisition network, which is mainly used for communication with data sources managed by DataMiner.
