We're contemplating replacing our existing BM 3.6 server with a new NetWare 6.5/BM 3.9 server - and are interested in RAID recommendations.

I've read where it is not recommended to use a RAID "array" for the "Cache" volume - and to use a traditional (non NSS) volume.

Any problems with RAID on the SYS volume? Specifically - RAID1 or RAID5.

At times (on other servers) - we've used RAID 1 and periodically "swapped" the mirror disk with a spare - to serve as a "backup" mechanism for disaster recovery.

Any thoughts?
