"The problem is that there is no such thing as "hardware RAID" there is
only "software RAID."  The "HW RAID" controllers are processors
running software and the features of the product are therefore limited by
the software developer and processor capabilities.  I goes without saying
that the processors are very limited, compared to the main system CPU
found on modern machines.  It also goes without saying that the software
(or firmware, if you prefer) is closed.  Good luck cracking that nut." --

Yes, thx!
And beyond that, there are HW RAID adapters and HW RAID chips embedded into 
disk enclosures, they are all HW RAID ASICs with closed software, not very 
Open Storage.   ;-)

best,
