NVMe-TCP configuration and storage connectivity

[mcarpendale]

Is there support for NVMe over TCP in Talos?

Ive used the UCS-X Blade with NVMe-TCP interfaces. Ive assigned IPs to these Interfaces and they can be pinged.
I can see the worker nodes NQN

But I cant figure out how to discover the NVMe Array

Thanks - Mike

Talos ships all required support for NVMe-TCP, but in order to mount external arrays in Kubernetes you usually use some CSI which would automate the process.

Hi @smira , there is two parts to getting NVMe-TCP working with K8S in general.

1. The non-proprietary Talos plumbing to recognise NVMEoF block storage, based on industry standards.
2. The proprietary storage vendor software, modules, services etc to mount that attached that block storage into a container either via a 1:1 mapping (via CSI driver) or via a software defined abstraction layer.

Regarding point 1 above, what are the general steps to recognise a block volume in Talos before we get to proprietary storage vendor software?

@frezbo i noticed you work on 10009 and I'm wondering if you could lend a hand in point us in the right direction?

CSI that's support nvmeof just works
