This white paper provides information about the high availability of SQL Server 2022. SQL Server implementations on Windows use the Windows Failover Cluster to deliver HA. However, in Linux deployments, a third-party solution such as Pacemaker is required. Furthermore, PowerFlex offers the unique ability to cluster block storage across AZs. As a result, you may use Pacemaker to provide high availability to the SQL Server instances if an AZ fails.
