Yes, it would work that way, but it would be safer to use a RAID 5
partition. Since it's a hardware RAID the OS has no difficulty booting off
a RAID 5 partition. Then you'll have the same RAID 5 features for your boot
volume as you have for your data volume. If a drive goes down you can
replace and rebuild without stopping the Xserve, regardless of which drive
fails. Also, carving off one non RAID partition from one drive prevents the
RAID controller from using that much space on the other two drive. So you'd
have the same total space.
I also have a Xserve G5, 3 500GB drives, and the hardware RAID controler. I
run it with a RAID 5 partition for the OS and, and two RAID 5 partitions for
data.
