I currently use HP DL360 G5's with 4 drives in them and at the hardware level, I create a single raid 5 and am using NetWare 6.5 with two volumes, one for sys and one vol1

I'm planning a migration to SLES-OES and in my testing it looks like I have to add two more disks to each server so i can create a raid1 for the / and a raid 5 for an NSS.

Is there a supported way to use just a raid 5 with 4 disks and have the root and swap on one partition and NSS on another ?

I do not mind getting extra disks if its a better solution.
