  This statement (extracted from a much longer posting) is right on the
  money - literally.  We are currently doing just what it says: migrating
  from a 5810 to a cluster of 4 5000's with SCSI drives,  for exactly the
  reasons given.  

  Our primary application is a mid-to-large database in INGRES (apx. 1GB
  now and growing at a rate of apx. 10MB per week).  One 5000 has replaced 
  the 5810 as a server.  When we can keep INGRES from crashing (which has been
  rare since version 6 arrived...), we see a rough 200-300% overall performance
  improvement over the 5810.
