That’s precisely what we do here. We use a lot of HP hardware, and just for fun (aka testing DR strategies), I moved all the drives between two test machines (RAID 0+1 across 6 500GB SATA drives).

The HP SmartArray controller detected the drives, found the array configuration, and proceeded to mount, check, and boot.

I, too, like to sleep at night...
