Yes, there is an ASM instance that manages the disks.

Our company put together a high-level presentation on ASM a couple of months ago for presentation at an Oracle event. It is not a kernel-level nuts and bolts internals presentation (it was for a mixed audience of technicians and managers), but it does provide an overview of what ASM is and how it works. There is a basic walk-through on how to set it up, query information in it once it is setup, etc.

You can snag the PDF off of our website if you're interested:

I hope this helps answer some of the questions.
