Hi
I have two Data Centers, a primary datacenter and a DR datacenter, so I planned to configure the following DAG configuration:
Primary site: 2 DAG members, DC's
DR site: 1 DAG member only passive databases, 1 DC
No file share witness.
If one member in the primary datacenter fails, all db's are active on the second member in the primary datacenter.
If the primary datacenter fails, I have to manually activate the member in the DR datacenter using the Restore-DatabaseAvailabilityGroup cmdlet.
What about the cas array? I planned to create a cas array in the primary datacenter. If the primary datacenter fails, I change the dns settings for the cas array to point to the cas on the member in the DR datacenter.
Is this a functional design?
Regards
Peter
