Here are my requirements. I have 2 data centers, and they are only a few miles apart with nearly no latency between centers. Both are on the same subnet. We need 2 SQL servers at each location. Plan is to have a primary at data center #1, with a replica of it here and the 2 at other data center #2 will be replicas of the primary from data center #1.
The requirement is we have a failover at the primary data center and if we lose the entire datacenter, we have a primary and a secondary at the second data center.
To clarify:
SQL1, data center 1 PRIMARY
SQL2, data center 1 has replica of SQL1
SQL3, data center 2 has replica of SQL1
SQL4, data center 2 has replica of SQL1
So do I set up a Sync copy locally at DC1 and a Sync copy at DC2 and then an ASync copy at SC2 on the 4th SQL server or just how to do I do this?
Thanks
