The DAG nodes within the different data heart would be prevented from activating any databases till they were in a position to contact all servers which are listed as members of the DAG. DAC mode prevents this split-brain state of affairs by requiring node majority earlier than a database could be activated. Node majority signifies that most of the nodes in the cluster — or DAG in this case — need to be on-line and reachable for a DAG node to have the ability to activate a database copy. If there are an even number of nodes in the DAG, then the file share witness may also work as a voting member to determine node majority.

The SAM is responsible for providing information to the opposite Exchange elements which are operating AM shoppers about which database copy is currently active. The SAM detects when a database fails and asks the PAM to initiate the failover occasion. The SAM isn’t responsible for choosing which copy of the database is activated after a failure. The DAG member server that owns the cluster quorum resource will hold the PAM function. If the DAG node holding the quorum useful resource fails, the PAM position will transfer to the server that takes possession of the quorum resource.
