I’m considering using NFS over InfiniBand (and IPoIB). Since prices are more-less similar I wandering which of the two should I buy?
Hello Zbuntowany,
Thank you for posting your inquiry on the NVIDIA Networking Community.
Below links will provide you the product capabilities for both adapters:
- https://www.mellanox.com/related-docs/prod_adapter_cards/PB_Connect-IB.pdf
- https://www.mellanox.com/related-docs/prod_adapter_cards/ConnectX3_VPI_Card.pdf
The Connect-IB is IB only. The ConnectX-3 VPI has the option to change the port type to IB or Ethernet.
Both adapters in general are EOL and majority of the ConnectX-3 models are EOS.
Our latest GA drivers, will not support Connect-IB anymore.
Recommendation would be to try to purchase a more recent adapter like the ConnectX-4 or 5 VPI, or even the ConnectX-6 VPI. All these VPI adapters will give you the opportunity to change the port type to IB or Ethernet so they will be more versatile to use.
Thank you and regards,

Thanks for a quick answer,
As I understand both are enough to run NFS over RDMA. So I don’t think I’ll spend money on anything better than Connect-IB. This is not for production but a kind of academic purpose.
Well, if you would like to donate some for our university…
