I would like to install SQL 2012 with Always on. We have two different Data centers (i.e. DC-1 and DC-2)
In DC-1, I would like to set up “Always on” (Synchronous mode) with Automatic Failover
and I would like to set up Asynchronous mode “Always on” (Asynchronous mode) with manual failover in DC-2.
Is it achievable? If so, do I need have “witness” server in DC-1(as I am planning to set up “Always on” with Automatic Failover)?
