Failover Environment - Unique or different IPs

Hello Solarwinds Support,

I’ve got a question:

I’m setting up a new Solarwinds environment. I’ve bought the necessary licenses already

I want to use the failover engine in an 2 datacenter environment connected by a WAN link and a Dark fiber interconnection. Which looks like in the graph.

Above IP’s are on the principal networkadapter. Which is an identical IP on each side(i.e. 10.239.80.1) + a diferent management IP on each side (10.239.80.11 & 10.239.80.21)

The private (Solarwinds Channel adresses) will be something like 9.0.0.1 but it did not show that in this graph.

Wtat the FailoverEngineAdminGuide does not make clear is the following:

1. 1.       It tells me that I can use identical principal networkadapter IP addresses.
2. 2.       But then it tells me I need different IP addresses because I use a WAN connected DR Site.
3. 3.       Last it tells me I need a management IP on both sides.

Now I’m confused. Is my graph correct? Or should the primary and secondary server (i.e. VCSW101) have:

Different Public IPs (10.239.80.1) and different management IPs (80.11. and 80.21)?

Or

Unique public IP and only different management IPs ?

Thanks in advance,
