Hi Team,
I am looking for some inputs with SQL 2014 availability groups.
I am planning to have 3 node WSFC with (2 node in primary with HA and 1 node in DR for DR). SQL box will run multiple instances for each product. SQL server in Primary (node 1 and node 2 ) will have SQL as failover instances. SQL node 3 in DR will be standalone. SQL server node 1 and node 2 will run 4 around instances , same number of instance will run on SQL node 3 in DR but in standalone mode. I need few inputs based on the scenario.
1. Can single Availability group hold databases from different SQL instances?
2. DBs running under 3 instances in node 1 and node 2 cab be put on single instance in sQL running in DR (as secondary replica)
3. Is there any limit to number of availability groups per SQL box or any limitation on number as per SQL instance?
4. Is there any limit to availability groups configured as synchronous or asynchronous replica? suppose can i have 4 Availailbilyt groups running all as synchronous ? (off course assuming bandwidth is good between Primary and DR data centers)
5. Availability groups are independent of SQL instances? and are per SQL based?
Regards
