I don't know if there is any "official" status here, but certainly most 
threads are about md raid - and this is the best source of help and 
information about md raid.  But dm-raid is also discussed here, and 
occasionally hardware raid comes up.  There are some regulars here who 
are very experienced with hardware raid and provide helpful advice - 
there are times when hardware raid is a better solution than software raid.

No one can be familiar with all the hardware raid implementations in 
common use - but maybe the OP will get lucky and someone here can help. 
  So it is certainly on-topic for the list, even if it is unlikely to 
get a useful reply.

That all sounds completely reasonable.  Thanks to everyone for the
clarifications!
