Are there any refrenc guide or supported topology to connect :
RACK 1 - 16 vxRail nodes - (2xS4148F-ON with SmartFabric Enabled) - that would be leaf
RACK 2 - 10 R740 nodes - (2x S4148F-ON) - that would be a leaf
RACK 3 - 2 x S4148U-ON - that would be a spine
Is that topology supported or we can not mix spine and leaf with smart fabric services ?
