I have Pretty much the same story.  SmartCard IV in two different
machines. A webserver and a new server.  Both have been running for at
least 1 1/2 years.  RAID 5 with five drives.  This means that one of the
controllers has only one drive.

	The only input I have is that one of the identical boxes was set up
with all of the drives on one controller (webserver).  The other had
them spread over the three controllers with 2 2 and 1 drives (News
Server).  The DPT that used all three controllers was more stable.  We
lost a couple of drives in the webserver over a  period of a few
monthes.  The News server has yet to loose it's first drive.

	Under FreeBSD 4 I believe the DPT controller is built into the GENERIC
kernel.  I am setting up one now and checked but have not even booted up
yet....

Back to work.
