we are ordering a new server that will have sco-unix latest and greatest version on it. I have never seen sco-unix before, i was wondering if i can setup a mirror, setup useing sco-unix, it can be mirroring, striping, or anything. I would prefer mirroring over 2 disk drives. Any helpful information or a place to start would be appreciated.
 
Do yourself a favor and use a hardware based mirroring/raid system. This will then be transparent to the OS. Most controller manufacturers still support (at least for now) SCO Openserver.

 
hardware RAID is the best solution...preferrably adapted or ami raid controller cards...
 
I have used with great success, and strogly recomend the software RAID drivers from SCO, called Virtual Disk Manager. I use it primarily for RAID 10 config, and it is the fastest RAID, and with better results than the hardware solutions we tried. Another benifit is the fact you use standard controller cards (available anywhere) and any size drive, with no future problems finding a replacement drive of the same capacity (older hardware RAID had these issues). With today's 160 cards and drives, you can place 4 drives in the striped array, and achieve disk I/O 4 times faster than a single drive. You will need a single boot drive, and mirror, making the total drives 8 or 10, but with the prices today, that is not bad for such a powerful server. I take it you are going to have many users, or do a web server?
 
As a low-end raid solution (if you're using IDE drives), you can install the Dupli-disk II by Arco. Otherwise, the votes for Adaptec or AMI solutions are probably best. As posted above, most hardware raid solutions are transparent to the os as long as a driver for the controller is available (and the hardware solutions are generally a faster implementation as well since you are not utilizing processor and memory resources to manage it).
 
Raid is good and highly suggested for performace, but you may want to look at rsync for backup.
