For model serial etc if the drives support a FRU then FRU device should 
be able to discover them assuming an smbus connection. Otherwise the 
CPLD on the HSBP that we have supports presence, so we can identify a 
drive is there, but not what model. I believe that's all we're 
supporting currently.
