Jared, I will have 2 volumes for my redo. but my question is not about the number of volumes for redo, it's about what should I do with that config. RAID-5 for data and index, and RAID-1 for redo and archived .... Should I put everything on RAID-10 ? I won't have to lose that space for my redo and archived b'cause they are the only one on RAID-1.
