SQL 2012
Hi Guys,
I am working in understanding more the feature <AlwaysOn>.
I have already worked with FCI (Failover Cluster Instance) and I would like to understand more about <AlwaysOn>.
Browsing internet/documentation I am getting more knowledge about <AlwaysOn> but a doubt persists:
1) Combination of FCI + AlwaysOn (2 SQL servers for FCI providing cluster instance: SQLCluster\SQLReporting + 1 SQL server (at least) for <AlwaysOn>: SQLAOn/SQLReporting)
If the FCI instance is called SQLCluster\SQLReporting, all the connections are mapped to this name.
But if the<AlwaysOn> feature is added to the system, in case of failure the name of <SQL Instance AlwaysOn> must be used therefore I am obliged to re-map all my connections to SQLAOn/SQLReporting.
QUESTION: IS it correct?
If yes, I do not understand the usefulness for the <AlwaysON> feature that lead to re-map all the connection.
In my opinion it should be a <MAIN> SQL Instance covering both <FCI> + <AlwaysOn>.
Thanks for your comments.
