I am setting up an AlwaysOn environment using SQL Server 2012 Enterprise Edition. I will have 3 nodes total, two nodes configured in synchronous commit, and the third node at a remote location as an asynchronous replica. Is it possible to use a dedicated replica vlan between the 3 nodes without any significant network changes? I know with 2012 and later you know longer need a stretch VLAN, but the examples I have researched up to this point have only had a 3 node configuration in a single subnet, or a dedicated replica VLAN between two nodes. My concern is if you can only have a single endpoint per server, how does the data get replicated at the remote site without a stretch VLAN?
Thanks
