Most definitely. While I think the kernel upgrade can be done with the
aarich driver remotely, it might be tricky the first time or two.

I did some bonnie++ tests on a piece of hardware with the aarich
driver, and then reinstalled with software raid. Attached are the
results.  Mudpuddle is the aarich driver and mudpuddle2 is software
raid.

Someone with more I/O knowledge than me will have to interpret the
results. To me it looks like a wash. Both ways have their strengths
and weaknesses.
