Apologies, as this was discussed recently.
There was an engineer from Charter Business who was setting up IPv6
trials for Charter Business customers recently. If he is still lurking
the list, can I ask that you contact me off-list to discuss this?
Thank You.

Hey guys,
Does anyone here have experience running copper 10Gbase-T networks? It
seems like the standard just died out. For us it would make a lot of sense
for our applications -- even if throughput and latency aren't as great. If
anyone out there knows of any *copper* 10 gig-t switches (48 port?)
Check out the Force 10 S4810 switch.

Mostly backwards compatibility; simplicity. We're planning for some
super-high-density virtualization/storage projects mixed in with lower
bandwidth gear, and sticking to one type of cable for everything would be
convenient. I thought DAC had some distance limitations as well.
This is all speculat
Gotcha. With SFP+ I think the only nod to backward compatibility would
be 1gbit RJ-45 SFPs, which can get a little spendy in large numbers
(although so can DACs).
As for distance, I admit I haven't encountered any DACs longer than 15
meters (~49 feet) -- not that I'm positive they don't exist.
We recently took possession of a building which part of it was used for
a teleco room by a Cellular company. The floor looks like crap. So we
were thinking about maybe just putting another new flooring on top.
Currently it has some type of tile looking flooring. I have been told

10Gbase-T doesn't make much sense for a new virtual environment. Once you
factor in the cost of the cabling and power, you probably would have been
better off with DAC or FET interconnects. Also 10Gbase-T does not necessarily
work with Legacy wiring, depending upon how it was run. Large bundl

Well, our new supermicro servers come with 10Gbase-T standard on
the motherboard.

If you are thinking of VCT, try stained+polished concrete. Naturally
