Hardware requirements for physical CORD POD

Hi,

I am wondering whether the hardware requirements regarding the servers' network cards for a physical CORD POD are still the ones mentioned here.

Both NIC vendors have made substantial improvements (both in terms of link speeds and programmability) since the Intel XL710 (i40 driver) and the Mellanox ConnectX-3 (mlx4 driver) NIC adapters.

Are there any updates in CORD's bootstrap scripts which are related to newer NIC hardware, but are not yet pushed to github or gerrit?

We are planning to buy the newest Mellanox adapters (either simple ConnectX-6 or Bluefield-2) which use the mlx5 driver.

Of course, I am willing to contribute to CORD if any updates are required, but I am trying to avoid duplicate work.

Thanks in advance for your guidance.

Best regards,

Georgios

Hi Georgios,

We still use those servers with those cards and we did not have the need to update those scripts so any contribution is much appreciated.

Thanks,

Hi Andrea,

Thanks for the prompt response, I will definitely strike back when we set up our new cluster.

One more question regarding CORD: Is there a possibility to use bare metal Kubernetes or Openshift+Kubernetes, thus getting rid of OpenStack?

In other words, are there additional cloud platform options apart from OpenStack+Kubernetes?

Thanks,

Georgios

Hey Georgios,

In the latests deployment at ONF we actually do use bare metal k8s deployed and managed with rancher, so it should be possible even with the CORD bringup scripts, although I’ve never tried myself.
