What scale are we talking here? personal (~ 100 message/day), small biz (~ 1000 messages/day) medium biz (~ 10,000 messages/day) large corporation (~ 500,000 messages/day) MSO (~ 1,000,000 messages/day) Galactic Gateway (~1.5x10E23 messages/day :-) ?? > > I'm working with an 80g drive just so you can use that as reference. > Any suggestions on slice layouts will be very welcome.

It's a toss up on which should be your root disk, but I'd put log and root together instead of spool and root. Of course, if you have three disks, separate root from log and spool altogether. Sizes will have to be determined on calculations for how many messages per day. I read a survey not long ago that suggested that the "average" message size has now grown to around 40K bytes. Seemed like a lot, but I guess with embedded graphics, multi-character sets and attachments, you can easily reach that figure over time. For large+ you will need multiple servers, with an industrial strength RAID solution on all of them. Sorry, I don't have any experience with Galactic Gateways :-).
