If I have a 2-Node AlwaysOn Automatic Failover Cluster Instance with a shared disk and RAID-5 or RAID-10 to account for a SAN failure with the same setup in a second datacenter with data propagation via SAN Replication, is there a way to benefit from using AAG in this scenario?
We're not looking to use AAG for scaling-out, offloading backups or READ-ONLY requests. Scaling-out can be implemented via new nodes and NLB. A new node can be added to offload backups. I'm not seeing a use for AAG here. I think the one feature that we'd miss is automatic page repair. I'm not seeing any other uses. But I am new to AlwaysOn.
Thanks for the help!
