Re: Exchange setup with 6 drives



That's overkill. It depends on how many drives your box can accomodate.
If possible, I'd go with
2 X 18GB miiroorod for OS. they can be internal
3 X 146GB RAID5 for data. Hot swap.
2 X 146GB for logs. Either hot swap or not.

The rational being that you want to be able to recover your array
IMMEDIATELY in the event of a drive failure. An OS drive can be replaced
after hours. Logs depends.
