Configuring Complex Load Balancing Scenario

Hello.   I'm trying to configure a virtual server using an especial load balancing scenario which is driving me crazy.   Specification:   2 clusters with 2 nodes each one. each cluster wi...

Are you saying that for example, you want cluster B to remain active even though cluster A may come back "up"?

 

If that's the case then i would do something like assign health monitors at a pool member level and i would configure the monitors that get assigned to the members in cluster A so that manual resume is enabled, that way you can return cluster A to being active when you desire.

 

Or i could have totally misunderstood your requirements :)

    Actually, I was taking in consideration to use "Manual Resume", but the point here is that both members of the cluster should work as a single node.

    Imagine this scenario from the picture above.

    Cluster-A, Node 1 - Passive
Cluster-A, Node 2 - Passive
Cluster-B, Node 3 - Active
Cluster-B, Node 4 - Active

    In case of node 4 flapping (down-up), it should be automatically re-enable to help Node 3 to serve the traffic.

    If both nodes (3 and 4) would be down at the same time, then the cluster should change from Active to passive:

    Cluster-A, Node 1 - Active
Cluster-A, Node 2 - Active
Cluster-B, Node 3 - Passive
Cluster-B, Node 4 - Passive

    I guess I cannot get exactly this behaviour using "Manual Resume"...
