Hi!
You were right.
After I figured that ASM can work with partitions we found a way.
My current idea is:
- We combine our six discs into three drives (Mirroring), using
RAID 1 on the controller
- partition each drive into
- Non-DB (Linux, Software, et.) (innermost cylinders)
- Db slow (archived logs)
- DB medium, fast
- DB Really fast (control, redo) (outermost cylinders)
- and let ASM do the striping across the three drives for
the DB stuff. That way we don't have to buy an expensive
RAID 10 or 0+1 capable controller and my boss is happy.
Lots of thanks for pointing me to ASM!
