Note I know whilst you are talking copper. IME 10Gbit copper is
nothing but a hassle. You are lucky to get 30Metres out of a run
without Negotiation issues.
I encourage you strongly to look to using Optical LX style fibre if
you are moving to 10G. The cost of structured cabling and the length
of runs is a lot cheaper than Cat6a/7 runs needed for 10gbit copper.
