Make sure you get a full height bracket when you order, that was one of the things I had to check as I recall now, since I have a full height tower system, not a 2U rack mounted system.

Yours claims RAID capability Ram> (assuming IR firmware) and the other seem to be no raid (may be Ram> IT firmware) I just flashed the standard LSI firmware from their site as I recall. I disabled any hardware RAID stuff as well. Since I can't just bounce the system to check, take what I say with a grain of salt. Ram> Both are from China, and like you say, not sure what I will get. I seem to recall I got it from someone in the US. The other trick I did was to put all my data volumes on the LSI controller, and just a pair of SSDs onto the internal SATA controllers. This way I know which devices I'll boot from, and it made it simpler to know I had updated and setup GRUB properly. You do want to test booting from a broken RAID1 boot device. When I recently did my big re-org, I found that to make it boot I had to move the working boot drive to the non-working slot, since of course the failed one was effectively /dev/first-drive and that's how grub needed to boot.
