Hopefully you have a redundant PS unit. Having a UPS is not going to help if your PS fails.
That's a very good point never thought of that. Acrtually this RAID 1 setup I'm planning is for my desktop machine, problem is is's not built like a server so there is not the traditional slid in bay for a second PS as do many 1 and 2u rack servers have. Unless there is some specialty product available that somehow fits in to a tower case.
Could you reccomend a redundant PS for a desktop machine (if they exist)?
The whole system needs to be designed for dual supplies. You can't just plop down two power supplies in parallel without some circuitry that attempts to monitor & balance them out.
I'm curious - why does your desktop needs so much redundancy ?
