Sun is capable of mirrioring the root file system. It although is only
raid1 you cannot have a raid5 root.

I have been running a root raid system for a while now. 

using the .90 patches with the auto-initialization features it is possible
to get a system to boot up and mount root on /dev/md0. There are 2
problems at this time:
1) you cannot create a raid partition from a non raid partition. So you
   end up having to use an extra disk or partition to create the system.
2) lilo or other boot loaders may have some problems with booting from a
   list of drives. So that if the main disk is un-bootable a secondary
   disk will be used to boot from. This is in some ways less an issue with
   lilo and more an issue with the BIOS.
