SMB Direct – SMB3 over RDMA

Interesting, the main things I've read for SMB Direct are from Microsoft, for their Windows Server implementation.

But with Apple's recent introduction of RDMA over Thunderbolt, that got my hopes up I could use it for storage, not only moving LLMs, but also for video file storage, where editing from one Mac to another (or over Ethernet, if that's supported) could be much faster, with lower latency.

What is the performance impact of soft RDMA over SMB this way, vs the traditional SMB on the IP stack?

is there some open source product who can leverage this or this just assume you have to use Microsoft stuff?

I was sure SMB3 was Super Mario Bros 3.

What, um... Are... Are people using samba to sync model weights between cluster nodes...?
