Re: ConnectX-3 FreeBSD support
My understanding is that in the new driver design wth FreeBSD 10 they're kernel mode drivers that don't need to be compiled into the kernel. You can build the kernel drivers by: cd...

HI, I've been investigating SR-IOV support on ConnectX-3, specifically MT27500 with CentOS-7 as the host and CentOS-6.4 as the guest. I've create one VF on my card and expose it to the VM. I wasn't too...

Yes, thank you. Can you try to set the speed on the Arista port to 10000, it may be set to auto negotiate.

Thanks Anand. We have to open a change-control with Sungard, usually takes the better part of a day.Keep you posted and appreciate your assistance.

Re: ConnectX3 FreeBSD 10 ethernet mode
It's actually a ConnectX-3 built directly into a SuperMicro motherboard (integrated)... so not sure how that equates. I emailed support with the ibv_devinfo as requested in the other topic. Thanks!

Im aware that the 10G Base SFP+ port operates at 10G. I dont want the port to try to auto negotiate the speed. Since there is also an Intel transceiver involved, It complicates things.By setting it to...
