Is possible to configure 3 Windows Server Failover Cluster - "active-active" cluster configuration (with sql server 2017) : 2 WSFC operational (replicated between them) and 1 WSFC - in stand-by mode ?
Is possible to configure this 3 WSFC as 2 Distributed availability groups: each operational WSFC to be in a Distributed availability group with WSFC stand-by group ?
The storage server of each server node for each WSFC (active - active configuration) should be replicated?
The storage of each operational Availability Group should be replicated with storage of stand-by group? Click to enlarge
