Thanks
Quorum: What is the recommended Quorum configuration for my setup, I'm assuming Node majority.
Correct, for a 3 node cluster node majority is recommended.
Do the servers span multiple sites at all?
Nope - All Servers are in the same DC
Would it make a difference if it was spanned across multiple sites?
DTC: Should all the nodes be a possible owner of DTC? Should the DTC disk be presented to all the nodes?
Yes and yes.
Doesn't this take away from the seperate storage selling point of AG's combined with FCI?
Failover: When configuring the failover mode, I am unable to change it to Automatic, is Automatic failover not supported when you combine an AG with an FCI or am I missing something?
Thanks
This link details the following
FCIs do not support automatic failover by availability groups: FCIs do not support automatic failover by availability groups, so any availability replica that is hosted by an FCI can be configured for manual failover only.
I'm no pro at HA but I can't seem to think of a logical reason why automatic failover is not supported when you have an FCI.
Hmm, Gonna have to rethink my approach then
So it's basically a tradeoff, You can have 2 nodes available to your primary but then you wont have automatic failover for your AG OR you can have a single node available to your primary and then have the safety of Automatic failover.
