I use these settings with SOFS clusters that are serving traditional SAN storage via SMB Direct, not just with Storage Spaces Direct. So the MPIO role is there when using storage that requires multipathing.

jaromirk commented 5 years ago

OK, makes sense. In S2D cluster it will keep not used (VMM also installs it by default)

nmdange2 commented 5 years ago

Yup that's why when you specify the S2D role it ensures MPIO is uninstalled
