Hi, i am planning to set up AlwaysOn with 20 databases, Automatic failover(synchronous) in my current environment, SQL server 2014,windows server std 2012 configure WSFC on 2 nodes ,
Node1 Node2 ( both Enterprise sql server editions), both servers located in 2 different locations
In the event of any failures below listed i want to failover from Node1 to Node2.
1.Operating System goes down
2.SQL Server Instance goes offline/Shutdown
3.Disk Failures
4.Network goes down
5.Cpu, motherboard goes bad
6.database goes offilne.
My questions:
1.where do i have to keep AGListner? node 3 ? and if yes node3 (for safety)--what are other options?
2.do i have to use SQL enterprise edition or will SQL express edition works?
3.what about operating server ? and Node3 should also configure WSFC?
4.I am also planning to use node3(SQL express) as distributor because i have replication from node1 to different server., do distributor works on Express edition ?
3. all my Fail over listed above(1-6) works with always on ?
please give some tips
