How about disk mirroring ? If you have a _mirrored_ database on two 2G disks and then add 2x2G (or may be 1x4G) and get spanned mirrored database. You get reliability due to mirroring and easy expansion due to spanning. Serge Babkin ! (babkin@hq.icb.chel.su) ! Headquarter of Joint Stock Bank "Chelindbank" ! Chelyabinsk, Russia
