Yep, they should work.  You may need to flash them with their Mellanox equivalent
firmware, but I'm not sure.  (doing that flash isn't very hard btw)

Not sure, as I've not needed to personally.  None of my storage (or other uses)
even fills one DDR port.  Yet. :)

I *think* the answer to that is yes,

Again not sure.  Other people here would likely know. :)
