While the technical details are factual, the tone of content of the doc shows a clear bias towards the fiber-optic which is the core of Cornings business -- they need to blast Cat6 since they need to sell fiber!
1 - the OP was referring to an install where the cable length in the 6 to 20 feet (2 to 6 metres). At those distances, none of the issues riased in the doc really have any significance.
2 - the posted topic is about IP over IB, IB connections don't support very long distances so worrying about cables of more than 50 metres is not appropriate.
3 - the need for server side connection of over 10GB/s will be several years away. 40/100GB/s connections are only being discussed for data centre backbones, where there are 100s of servers which would be connected to intermediate switches, which would need to be tied together using 40/100 GB/s connections. When you consider that a *single* HP ProCurve A12500 switch can support **512** 10GB/s connections (with intermediate 1 Gb/s switches which could connect at 10GB/s to that switch, more than 5120 1Gb/s connections could be handled that that single switch), the need for interconnects to another switch is something that very few installs would ever need to worry about.
