no 10G twinax option for network speed

[maverickhunterx]

Hello all. I recently built a server for SAN purposes and I have two intel x520-da2 cards. I have plugged in twin-ax cables and on my switch side I see 10G, however on my nas4free side, I see "media: Ethernet autoselect (autoselect <full-duplex>). I just want to be sure this is synchronized at 10Gb. there seemingly is no real way to tell. I read an article with one person being able to choose "media: Ethernet autoselect (10Gbase-Twinax <full-duplex>)" with ifconfig -m but I see no such option. Please if anyone can provide any insight, that would be most appreciated.

PS: I also have these interfaces in etherchannel mode and on my switch I see it linked up at 20Gb.

revise that is supported, and must work: http://www.freebsd.org/cgi/man.cgi?quer ... ormat=html

do an iperf test.

if the speed is about 1000 mbit then its working.
the gui does not have an option for 10g.

ran iperf and got 3.02Gbits/sec. I was expecting more...

Is that about right? I only configured the client with a single 10gb link. I have 20gb ether channel to SAN.

[b0ssman]

not many people have 10gbit atm.

try without lagg first. see what the cpu utilization is on both ends.

Alright, so I ran another iperf with more processes and was able to push 9.89Gbits. So that seems to be ok. Thanks all for your help.
