Depends on why you ask...
If you are asking because you want to protect yourself from data loss, then the
minimum is three redundant disk arrays... one for the OS & Exchange Program
Files, one for the Databases, and one for the Database Log Files. Which means
a minimum of 6 disks (3 RAID1 arrays), preferably 8 (raid1 for the OS &
database, raid5 for the log files, and a hot spare)
If you are talking about performance only, you can actually usually get better
performance by having a raid1 array for the OS, and a raid1+0 array split into
two partitions for the database and log files.
I guess it depends on the installation... for a company of less than 250 users,
you can get away with less, since you will never reach the threshhold where you
notice.

Conversation: [windows2000] Exchange installation/volumes
Subject: [windows2000] Exchange installation/volumes
I remember at one time it was recommended to install Exchange on a server
with a physically separate Windows system volume (preferably mirrored), then
have Exchange & the Information Store installed on another physically
separate set of drives (either mirrored or RAID 5, depending on the amount
of total storage required/planned for Exchange).
Is this still a recommended standard, or is it outdated considering the
advances in hardware performance?
