It's either a pleonasm, or you're saying that the unit has 4 power supplies. Either way, it's wrong. It either has redundant power supplies, or it has dual power supplies.
Anywho, it's a nice unit, but the price is probably going to be all wrong.
Listed at $2400, they certainly aren't giving them away.
I think dual redundant makes sense. It is dual is the nunber of PSUs, redundant is desvribing theit setup. It could be dual non-redundant (2 PSUs, each with dedicated work load) or (in this case) dual redundant (2 PSUs, both sharing the same workload.)
You can have dual PSUs in non-redundant settings (one powering the system, another the HDDs, other systems have dual PSUs with one powering everything except the multi-GPUs and one just for the GPUs). And you can have non-dual redundant PSUs (3, 4, 5) so either of those statements alone would not describe this system accurately. Hence his use of dual redundant is perfectly fine and needed in order to convey the actual setup of the system.
The Infiniband port will be as useless as a 10GbE port, the Atom doesnt' have the power to drive that type of high bandwidth card. Also you need RDMA protocols to take advantage of any of the cpu saving features.
FreeNAS on a microserver can easily saturate a 1G line. You're obviously not going to get anywhere near 10G speeds without RDMA, but there is room for improvement.

Since there is a free PCIE slot, I wonder if you could plug an infiniband adapter into this bad boy instead of a 10 GbE?ganeshts - Monday, March 4, 2013 - link
Hmm.. Not officially supported yet by QNAP, in its OS but I will ask :)shank15217 - Monday, March 4, 2013 - link

So many of these "higher end" NAS units go for Atom instead of ARM. I haven't seen a single one go for Bobcat from AMD. Why not?
