I have used least 3 RAID software packages on Suns
Sun Disksuite is a Sun product that works entirely in software
Sun RAID Manager 6 (the very poorly named rm6) works only on hardware RAID controllers
Veritas Volume Manager can work with either hardware or software RAID, but is not by Sun, although it is included in some Sun hardware RAID products The one thing you can't give for your heart's desire is your heart. - Lois McMaster Bujold
