You plan to migrate an on-premises database to Microsoft Azure. The planned deployment will include an Always On Failover Cluster Instance of Microsoft SQL Server. You need to implement a storage solu

Azure Table Storage is a NoSQL key-value store and is completely unsuitable for storing SQL Server relational database files or backups.

Storage Spaces Direct (S2D) is a technology that aggregates locally attached disks on Azure Virtual Machines to create shared storage for a Failover Cluster Instance, rather than being a standalone Azure storage service that is implemented directly for the database files.

Although Azure Blob storage cannot directly host the primary data files (MDF/LDF) for a SQL Server Always On Failover Cluster Instance, it is a common and cost-effective solution for storing SQL Server database backups. Blob storage can also be used for a cloud witness share for the Windows Server Failover Cluster, which is a component of an FCI deployment.

SAN virtualization is a technology for managing and provisioning storage in traditional on-premises data centers and is not an Azure-native storage service or solution for Azure deployments.
