In my company we have chosen to implement Multi-site SQL Server Failover cluster. Basically Data center A has 2 nodes (Active/Passive) and Data Center B geographically located acts as the DR. I believe there will be a SAN replication from Data Center A Data Center B.
If in future we want to implement a Multi node AlwaysOn and availability group HADR solution. By that i mean (Data center A has 2 active node and 2xSANs, and DBs are part of a group. Data center B has an Active node and its own SAN which act as a DR site). Can you guide me on how to implement this process or articles that explain this in details.
How can I migrate from a geo-clustreing to an High Availability Disaster Recovery? and what should I consider?
