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.

Guys,
the XServe/XRaid comes with FibreChannel
I stand corrected. That should help things some; it makes it more of a small
tradeoff between performance and storage size for the drives.
