Re: Anyone familiar with Apple Xserve RAID

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.
