The question doesn't compute. :) The issue, as I believe another poster pointed out, is that reaching quorum is impossible with an even number of live servers that don't have access to the FSW. The cluster will go offline.
Warning: I don't know your design goals. Based on what little information I have, I would tend to suggest you have two DAGs, keeping the same server distribution. Site A has two servers for DAG-1, site B has two servers for DAG-1, the FSW for site A is in site A. Reverse that for DAG-2 being homed in site B. Regards, Michael B.

One reason for posting my question was that I could not find anyone else who had done it this way. I was told the reasoning behind this is that if even if we lost site A we would still have the 3 members in site B plus the fsw in Site C. is that logic flawed? Can you be more specific about what quorum issues we might face? BTW the intention is to have active mailboxes in both sites A and B. we are at the design/test phase so not written in stone yet.

Are there any drawbacks with doing it this way? Anybody have any good reasons why we shouldn't do this? Thanks in advance.
