That's something one should do for these Adaptecs :) And that thing they
are putting into Proliants instead of the RAID controller.
If it's fast *and* does not drop disks from the array for no reason (HP,
I'm looking at you here) - stick with hardware RAID, always said that.
Your approach gives portability, nothing wrong with that.

I agree with you. MEGACli was designed for Matrians, and storcli can be
hardly called an improvement over it. But at least you can monitor
separate disks via smartd/smartctl, so it's not that bad.
