Only one FCI partner can host a replica for a given availability group. An availability replica can be hosted by either a standalone instance of SQL Server or an FCI instance. You can set up a second layer of failover at the server-instance level by implementing SQL Server an FCI together with the WSFC. SQL Server Failover Cluster Instances (FCIs) and Availability Groups

If you delete and re-create a WSFC, you must disable and re-enable the Always On availability groups feature on each instance of SQL Server that hosted an availability replica on the original WSFC.įor information about running SQL Server on WSFC nodes and about WSFC quorum, see Windows Server Failover Clustering (WSFC) with SQL Server. A Windows Server or WSFC administrator will need to force a quorum and then bring the surviving cluster nodes back online in a non-fault-tolerant configuration.Īlways On availability groups registry keys are subkeys of the WSFC.

If the WSFC goes offline because of an unplanned disaster, or due to a persistent hardware or communications failure, manual administrative intervention is required.

The overall health of a WSFC is determined by the votes of quorum of nodes in the cluster. In contrast to database mirroring, there is no witness role in Always On availability groups. The quorum for Always On availability groups is based on all nodes in the WSFC regardless of whether a given cluster node hosts any availability replicas. The WSFC monitors this resource group to evaluate the health of the primary replica. A WSFC resource group is created for every availability group that you create. The only exception is that while being migrated to another WSFC, an availability group can temporarily straddle two clusters.Īlways On availability groups relies on the Windows Server Failover Cluster (WSFC) to monitor and manage the current roles of the availability replicas that belong to a given availability group and to determine how a failover event affects the availability replicas.

Furthermore, each availability replica of a given availability group must reside on a different node of the same WSFC. To be enabled for Always On availability groups, an instance of SQL Server must reside on a WSFC node, and the WSFC and node must be online. Windows Server Failover Clustering and Availability Groupsĭeploying Always On availability groups requires a Windows Server Failover Cluster (WSFC). For information about Always On availability groups concepts, see Overview of Always On Availability Groups (SQL Server).
