Primary reason for this is because current Gen1 C-N-A's simply do not fit in
1RU systems.  Where 2-4RU systems are purchased for the primary reason of
adapter real estate, the Gen2 C-N-A's offer a path to 1RU.

Not to mention less power in connecting to the server to one access layer
switch fabric, rather than two.

Right, the pitch is largely: "same price, smaller, more capabilities, and oh
by the way, less power".

Of which there is no disadvantage in C-N-A's ... which lead us to this
tangent  :)
