Our Spac solaris 10 box has only three disks (budge limitation), and they were configured with hardware RAID 1 (3-way). Obviously, the disk performance is going to suffer since both OS and DATA will live on the same mirrored disks, however, this part of disk configuration puzzles me even more: a soft RAID 5 is added on the top of 3-way mirroring for two slices (c0t0d0s5, and c0t0d0s7) where Oracle data will reside. Can any RAID expert comment on it please? It seems to me our OLTP type of Oracle Application will suffer from slow writing with RAID 5, not that disk space isn't an issue.
