This caused me some grief, both in planning and when I got my hands on all the parts. In my last post, you can read about the my discovery and elation that RAID controllers can be added to systems (which seems a little silly in retrospect). In researching this specific kind of RAID controller, I read that I needed to make sure I got the right cables. “OK, sure, I’ll pick up one that come with cables” I thought to myself, not realizing where each cable would go. I got this combo (listing here), and thought everything would be great.
