Yes, software RAID is for bungee jumpers...

I've been concidering following (high-end NT box): NT,Oracle: raid1

redo:         raid1
rb & tmp:     raid1

(if that's 3x(2 disks) or a compromise, depends on activity and $$$)

data & index wide raid5 (if $$$ then raid1+0) (no, I don't separate data and index, let the raid spread the I/O) (1 wide raid is better than 2 narrow ones, right?)

archive logs: raid0 (several 9Gb disks)
(part of this is Compressed directory, which holds last full export,  (and if possible)even last cold/hot backup)

If something blows up, everything needed for recovery is already on the disk...
(well, unless raid0 breaks, but then I can limb forward after switching archive destination)

Did I miss something?
Is this a dream or what?
