What kind of storage configuration would you recommend for a small Exchange server deployment supporting about 50 users? Probably won't grow past 75 users in 3 years. Majority will be "medium" users, with a few "heavy" users and BlackBerry clients.
So far, everything that I've read suggests keeping the Exchange database and the transaction logs on separate physical drives, and keeping both of those off of the system drive. It also says to put the transaction logs on something fast, like a Raid 1+0 array. Considering that all the data needs to be protected, it looks like this would be an optimal setup:
System drive - 2 small drives in RAID 1 Exchange database - 2 big drives in RAID 1 Transaction logs - 4 fast drives in RAID 1+0
However, using 8 drives for a tiny Exchange server seems like incredible overkill. Where would it be safe to cut back?
