Business value

For on-premises customers who run the database with high availability features, failover is now faster.

Feature details

MultiSubnetFailover enables faster failover for all Availability Groups (AGs) or Failover Cluster Instances (FCIs) in SQL Server 2012 or later and it significantly reduces failover time for single and multi-subnet Always On topologies.

Diagram of how MultiSubnetFailover works

In this release wave, we added a new server setting EnableSqlMultiSubnetFailover. When this is set to true, MultiSubnetFailover is enabled on the connections from the server to the database.
