Thank you for your post.
Please find answers to your questions below:
1. This card supports Network Operating Systems, such as Windows Server 2012 and 2008 R2.
2, 3 and 4 - The modules and cables you're using is not supported. We have listed the supported modules and cables in Product Brief.
5. I'll have further check if modules are hot swappable or not. Will update you on my findings.
Thank you for your patience and understanding.
Thanks for your reply.
The Product Brief you have linked to is for the XL710, not the X710 card. The X710 doesn't have 40G QSFP ports so the supported modules in that document don't apply in my case.
I have just come across Intel® Ethernet Converged Network Adapter X710 Series — Which SFP+ Modules, SFP Modules, and Cables Can I Use with the X… - which seems to cover the supported modules. Now it appears based on that, that the Cisco Twinax is compatible with SFF-8431 so I guess it should work (although if you have reason to suggest it won't work I'd be very interested to hear).
Is it likely that we could see the 1G Copper SFPs supported in the future or is this a hardware limitation?

Thank you for replying. I see you're inquiring about X710 and not XL710 model - my mistake.
Yes, Cisco* Twinax cable would work with this adapter since it is compatible with SFF-8431.
Let me share with you the Intel® Ethernet Converged Network Adapters X710 Product Brief.
With regards to your inquiry on 1G Copper SFP+ modules, it is likely that it will work with this adapter. Since we do not manufacture 1G Copper modules, there are third party companies manufacturing these modules performs tests for compatibility with our adapter. Just like what we have for Intel® Ethernet Converged Network Adapter X520 Series. Please refer to the link below:
Hope this is helpful. Feel free to contact us again if you have further inquiries.
Thanks for your help Sandy, closing this off as correct.
