If that single RAID5 (which holds everything) fails... You will lose everything.

Disks are now so much bigger than they used to be. And there are some great budget servers available with room for just a few disks, which cost a good deal more when adding an expansion cabinet and controller needed to support the number of drives you need for the 'standard' way of doing things. That's why, for the real low budget, small numbers of users scenario, we do exactly what you suggest, Craig: all the disks go in a big raid, and we partition 3 logical droves on it. Sure, we're taking a performance hit; but our users don't even notice. It works great for <50 users. If they're extra jumpy, we keep one disk as a hot spare, ready to replace any failed disk immediately. We've been doing this for all our small servers for a couple of years now, and we've never had a controller failure yet.

Stick with what Steve recommends. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Molkentin Sent: Monday, July 26, 2004 9:59 PM To: Exchange Discussions Subject: RE: Comments on performance Craig, Ultimately, it depends on your expectation of load and budget, but my thoughts would be: Raid1 - Programs (programs and logs *could* share the same mirror) Raid1 - Logs Raid5 - database I am happy for that to be shot down with the better solution - there are more out there that know more than I. themolk. > -----Original Message----- > From: Craig A.
