I would guess it [CRS-X] is too power and cooling inefficient. The
same for the NCS6K...

The longevity of the NCS55K could be questionable although I'd expect
the 8Ks to be more expensive, I expect the Silicon One chip to be more
featureful and where the NCS55K sines is with dumb packet pushing. The
NCS55Ks are high throughput and a relativity low price point with
fewer features. They are also much more space, power and cooling
efficient compared to the NCS6K and presumably the CRS-X but I don't
know those boxes very well. Also Cisco are pumping new features in the
NCS55K right now, so I don't think it will be dropped any time soon,
it serves a different purpose and price point than the NCS8K as far as
I can see.

Yeah I don't think there is any point buying NCS6K now. I think the
NCS55K has superseded it. I'm not sure there is a place for larger
ASR9K boxes either. We tried to re-purpose an ASR9922 recently that
was pulled out and it just wasn't cost effective; given the number of
packets they shift whilst consuming a whole rack of space and $LOL
amount of power, if you just need edge capacity with minimal features
and buffers it's not efficient.
