Cool! As I understand it, yes. Not being a guru about this kind of stuff, I don't know the in's and out's of doing this, but this was one of the big deals about the Intel RAID controllers - they all used the same drivers and firmware (being based on the ICP Vortex design and software, you'd expect that!). You could swap controllers and models of controllers (even in Windows 2000!) and the machines would just work. The latest Intel RAID controller (U42X) breaks this model and I don't believe it is yet supported in FreeBSD. Something about a new RAID architecture on this and 'all future controllers'. For now though, the S14L should be a good-to-go hardware RAID controller for FreeBSD.
