At work I usually RAID 1 my 256 MB /boot with all the hard drives that
are also in the raid5/6 arrays. This is usually 6 to 10 drives. On top
of that I keep the OS on its own smaller raid 5/6. So my partitions on
every disk are usually

boot raid 1 (over all disks)
swap (seperate swap on all disks)
root raid (raid 5/6 over all disks)
data raid (raid 5/6 over all disks)

on top of the data raid I usually use lvm for simpler partitioning and
spanning across a second raid if I choose to do that in the future.
