Mount points and SANs

Where can I read about how mount points and SANs work? In other words, at
the driver level, how do they fit into the stack?

I’m playing with the minispy sample and it appears it’s not seeing activity
going to a mount point nor to a SAN-mounted drive, so I’m trying to learn
more about it all works.

Currently going through the index of the Nagar book looking for answers but
not seeing the big picture yet.

Thanks for any pointers.
