I use the Dell 2850 and 2950's (plus a pile of older Poweredge 4600s and a few other models) a lot in the systems that I administer at the college, Rod. They're very good machines.You've got what Dell terms a "RAID 1 + 5" configuration (OS on RAID 1, data on RAID 5), which I've been using very successfully on several dozen servers over some five years now. If you stay with that, the only change I would make would be to add a hot spare (extra HD, online and configured to be available for automatic failover) to your array, so that one additional HD is always there. If you're talking real fault tolerance, I assume that you've got Dell's redundant power supplies, ECC RAM, etc., etc. You know that score...
300GB SAS HD's are the minimum that I would use for your application.
RAID 6 is interesting, but still young...and it does have some costs as well as some benefits. (See link below for more.) I'd wait until Dell integrated it...don't remember seeing it as an option on any of my recent Dell Premier site server building systems.
Best wishes to you with the upgrade project. Believe me, I know what's involved in a decision like this....
