Files are kept safe simply by RAID-5 mechanism. RAID-5 protects against any single disk failure (double disk failure can wipe it all out) and that is precisely why Mogens is such a zealous proponent of RAID-5 systems.

I read some posts on here with shared storage such as SAN and Network Appliances its no longer necessary to multiplex datafiles on different disks, since the storage array handles that for you.
How do you ensure that control files and redo log files are kept safely apart so that no one disk failure in the shared storage can take them all out?
According to the OFA(well the abbreviated version I have in front of me) 4-5 disks is optimal for multiplexing. Does this no longer apply with shared storage? How do you ensure database available with shared storage? if your not multiplexing datafiles?
I may have read some peoples posts incorrectly. Im just digging into backup and recovery.
