I'm getting ready to migrate a NW 6.5 SP5 CPR server to a Dell 2950
with a SATA raid array. Should I stay with SP5 or install SP6 (with
the wiki recommendations)? The server mostly does file and print
services and also hosts a MySQL database.

Are the SATA drives a Really Bad Idea? The server has 4 SATA II drives
installed. I did read the previous thread on SATA. We own Portlock
Storage Suite and the linux boot cd v3.6 does contain the Volume
Defragment for NetWare. From the readme:

The following versions of Novell NetWare are supported:
......Novell NetWare 5.0, 5.1

It's my understanding that NSS is the same for NW5 and NW6
