[ale] 10G networking

[Lightner, Jeff]

When I read up on all this recently it appeared to me you could either have the fibre SFP or the copper rj45.

We've run across a couple of servers now that  offer the rj45 on the motherboard for 10 Gb but our Nexxus switch is fibre so we have to have the SFP - We've used the Broadcom HBAs successfully in our Linux systems for connections to that switch.

On at least one Dell server I recently looked at they had various daughter cards for the onboard networking so you could get a choice of all 1 GB RJ45,  or 2 x 1 GB RJ45 + 2 x 10 GB SFP, or 2 x 1 GB RJ45 + 2 x 10 GB RJ45.   From what I read there it appears this is something they're moving to on their PowerEdge line because of differing requirements.

I know that we have some special copper cables that have SFP+ ends.  We are going to Cisco 10GB switches out of Broadcom 57711 cards.  They were in range of several hundred $$$ each, but cheaper than the fiber option.  I can get the info from our Network team, if that is of any use to you?

Is there such a thing as a 10G SFP+ module that has an RJ45 socket instead of fiber? Not a direct copper link but for cat6/6e/7 ethernet cable.

Looking at a few 10G switches and Netgear has a 12 port 10G with rj45 that way affordable but my existing gear all uses sfp+ lc fiber.

The new NetworkManager in centos 7 support link aggregation directly with very cool failover and high bandwidth methods that are supportable in the switching I'm looking at from supermicro (24 port 10G all sfp+ for under $6k).
