Can we use Azure Premium File share for Windows Failover Cluster with Zone Redundancy

Hi Samanta, If you referencing to use for Premium storage for NetWeaver replication cluster in Windows you can't use blob and you can't use Premium you should use only LRS: https://learn.microsoft.com/en-us/training/modules/implement-ha-sap-netweaver-anydb/7-exercise-set-up-windows-server-failover-cluster If you referencing failover cluster DB for Windows you have to use Azure there should be a third partly cluster softwire and doublet there is any for HANA on windows and for SQL Server you can use Windows cluster via SQL Server Always on: https://learn.microsoft.com/en-us/training/modules/implement-high-availability-for-sap-workloads-azure/10-explore-sql-server-availability For sap enqueue replication(ERS) you must use some sort of third party softwires in Windows to be able to cluster fail over which Windows server do not support by itself Limitation of shared disk in Azure (Microsoft quote): -Using Windows Failover Cluster Service with shared disk configuration for the DBMS layer is NOT supported in Azure VMs. Instead, in Windows to provide high availability, customers should consider using non-shared disk solutions, such as SQL Server Always On, Oracle Data Guard, or HANA System Replication. -SIOS DataKeeper Cluster Edition is a third-party solution that you can use to emulate a shared disk for your cluster replication in Windows Servers.Shared locally attached disks are not natively supported on Azure VMs. Thanks,
