Okay, thanks. I was concerned that the 166AXP would be struggling under
the parity load. It's not really a high volume service, but I didn't know
what kind of load it would require. I'd prefer to have that 1.5GB
available.

That's what I thought, but didn't know if 0+1 was different than 1+0 and
didn't understand how mirroring would work with three disks, etc. It
looked like I wanted RAID 5, but the CPU usage concerned me.

I suspect it might be as well. It's all SCSI-10.
As for additional backup, I also have tape so it's not a SPOF. I'm not
really sure what I'm going to put on here, but I suspect it will be used
primarily for CVS data. This UDB has 72MB RAM so I guess that's another
negative for mirroring due to the page cache.
Thanks for the help!
