To be more clear. The 4 D40's are a mixture of database, logs and disk
pools. One VG for database, one for mirrored database and one for data
storage pools.  Four full D40's just for a database would be quite
unnecessary. No raid anywhere, all raw disk consisting of one LV per disk no
matter if it is database, log or disk pool related.  Mirrors are absolutely
on separate spindles which are also on separate D40's.
