Actually you are both are right and wrong.  The XRaid uses FibreChannel 
to communicate to the host machine(s).  The Raid controller is a 
FibreChannel controller.  After that there is a FibreChannel to UltraATA 
conversion for each drive, separate ATA bus for each drive.

What I am curious about is if this setup gets around ATA fsync problems, 
where the drive reports the write before it is actually performed.
