I have two queries on achieving HA using Always on with and without SQL FCI.
1.When combining SQL Failover cluster instance (FCI) or Always On Failover Cluster Instances with Always On (SYNCHRONOUS COMMIT, AUTOMATIC FAILOVER) do we get automatic failover to another node when following happens;
a. Instance goes down.
b. Server goes down
c. Mother board, memory, network issues
d. Quorum with file share witness is offline
e. Is Always On failover automatic or manual
f. How does Listener points to another node when instance level failover occurs
2.When Always on (SYNCHRONOUS COMMIT, AUTOMATIC FAILOVER) is installed without SQL Failover cluster instance (FCI) or Always On Failover Cluster Instances? do we get automatic failover to another node when following happens;
a. Instance goes down.
b. Server goes down
c. Mother board, memory issues
d. Quorum with file share witness is offline
e. Is Always On failover automatic or manual
