If you are creating a SQL Sever failover cluster instance (FCI) in Azure, you can use Storage Spaces Direct (S2D) and configure Storage Pools to set-up the Cluster Storage.

I have been advocating the use of SQL Server Failover Cluster Instances (FCI) to provide high availability for over 10 years. However, during a review of our reference architecture the question..

A quick look at the [hardware and software requirements for SQL Server 2008 R2](https://msdn.microsoft.com/en-us/library/ms143506(v=sql.105).aspx) indicates that it is indeed supported.
