If he is doing a fresh install, you can select custom partitioning and do
it during the install. With three drives, you will most likely want to
use raid 5 for most of your partitions. /boot should be on a raid 1 partition
mirrored accross all three drives. Depending on why you are using raid,
you might want 3 separate nonraid swap partitions, a raid 0 or a raid 5
swap partition.

If you particularly like using raid 1 (for example you split mirrors to do
testing or the like), then you can also use that buy having 3 raid 1
partitions split accross the three unique pairs of drives.
