Just a small question for those people who use external logs. Do you put
them on the same disk (or disk set) or do you put them on a seperate
disk (and indeed, seperate controller).
If you do put them on a seperate disk, is it mirrored? To a seperate
controller?
I'm just thinking, that to build a fault tolerant, yet high throughput
server could start costing a lot of cash... On the otherhand, does
(hardware) RAID5 push the performance down so low, that an external log
won't improve things anyway.
