Hello,
If you search for SnapDrive components in the HWU it gives support for both ONTAP DSM 4.1P1 as well as Microsoft MS DSM.
https://mysupport.netapp.com/matrix/imt.jsp?components=946;75304;77073;&solution=4&isHWU
The supported version of VSC only goes to v6.x since v7 only supports SnapCenter, which does not use SnapDrive...so is not listed 🙂
However, the only real benefit of using the ONTAP DSM is the GUI that shows the owning VSM, otherwise the Host Utilities Kit together with the Microsoft MS DSM provide the same functionality.
Hope this helps.
Cheers,
Grant.
