Looking for some advice on to how best improve fault tolerance and possibly disk performance in this oldish Dell PowerEdge Regarding drives dying together, I definitely wouldn’t want to ignore this for days, but if I am in zata position for some reason that I simply can’t get on site the day of or the following, the more redundancy the better.

With that time and cedc, I can honestly tell you that RAID 10 works best in an “always-on” server situation. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Ubuntu Forums Code of Conduct.

Thinking about it more critically, it would rqid adding more complexity than it’s worth. My goal is to provide a few days of safety should a drive die and I’m unable to get on site within 24 hours. I’ll be rad my services back to them and want to shore up reliability as much as possible.

Submit a new text post. But that is still 2 drives, vs the 1 drive tolerance of RAID 5. CERC controllers are nice, but pretty out of date.

More details on the rules may be found in the wiki. And you are correct, the 2 drive fault tolerance is only true if the 2 drives are in opposite mirrors. Obviously some less than ideal things going on here, no hot spare, backing up to a consumer drive, etc.
