I used SurfRAID Triton external RAID units connected to Sun X4100
boxes via LSI Fibre Channel cards.  I run them as RAID6 plus hot spare
with a total of 16 drives.  This is extremely fast and provides for up
to 2 disk failure.  The key is to have 1 or 2 gigs of cache on the
RAID units.  I also crank up the RAM on the servers to at least 20Gb.
