How Does Azure Stack Utilize S2D?

Just a brief on where and how S2D was fit into Azure Stack box!

Azure Stack uses S2D in the hyper-converged mode. In addition, Microsoft made the following design choices for Azure Stack and S2D:

Two virtual disks created per node in the Azure Stack deployment. One for tenant storage and another for ephemeral storage such as pagefile blobs for virtual machines.

Storage Bus Cache will be SMB3 and SMB3 direct

Storage in Servers with locally attached disks are listed below:

    • Serial ATA (SATA)
