OS-integrated software + CSV/SMB (Native)
VHDX (Docker in Linux VM or Windows Server 2016 VM)
Native: With Windows Server 2019 (plus latest updates) there is support for mapping container data volumes on top of Cluster Shared Volumes (CSV) backed by S2D shared volumes. This allows a container to access its persistent data regardless of the physical cluster node where the container resides.
With Scaleout File Server, created on top of an S2D cluster, the same CSV data folder can be made accessible via an Server Message Block (SMB) share. This remote SMB share can then be mapped locally on a container host, using the new SMB Global Mapping PowerShell.
Docker: When leveraging Docker inside a Linux or Windows Sever 2016 VM, virtual disks (VHDX) is configured and attached to the VM. Inside the VM one or more virtual disks are mapped to the Linux/Windows container.
