I need information on hosting a DAG stretched across 3 data centers. I haven't found any reference scenarios yet. I'm actually trying to combat this proposal! The scenario would be something like:
- Data center 1 located in India replicating databases to servers in data center 2 in California.
- Data center 2 in California hosting the quorum and its own active databases replicating to Data center 3 in New York
So India's databases are replicated to California but California's are replicated to New York.
The first detraction I can think of is, and this is if I understand correctly; if the WAN link goes down between India and California the India servers will lose quorum and there will be an outage?
Let me know what you guys think. Thanks.
