All of my experiences of OnLine on RAID have been disastrous, and in spite of copious numbers of provocative postings over several months both here and in the HP conf (HP are big pushers of RAID), I have yet to receive one single response that says a kind word about it. RAID cuts across the grain of the very way OnLine was designed to work best, ie give OnLine the maximum number of separate, raw disks. Start messing about with that and you can really slaughter performance. Don't do OnLine on RAID kids. akent@cix.compulink.co.uk (Andy Kent) -------------------------------------
