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. greg pavlov, fstrf, amherst, ny
