maintaining quorum with qdisk when backend cluster communications is gone

Greetings!

 

I have a two node cluster with a quorum disk.  I have two front end nics servicing application traffic and 2 backend nics on a private network for cluster communication.  I want the cluster to stay quorate if I lose one of my backend nics and still have access to my quorum disk.

 

I am having difficulties creating a working configuration for this scenerio.

 

Bottom line is, if I lose a backend nic, the front end nic is still serving up my applications so, the cluster noded are still technically functioning in spite of the fact that I may not have internode cluster communications.  My thought was that adding a quorum disk would allow the cluster to remain quorate even if I lose backend communications.

 

Does anyone have any thoughts on this?
