L40/L40S didn't have it either, which was announced late and felt like a gut-punch for the rare actual non-AI use-case at the time.

A40 nvlink was limited though, one-to-one (bridge), never saw it daisy-chained or nvswitched (might have just not seen them myself, they may have existed).

Of course it doesn't; artificial segmentation because they really want you to buy their even more expensive datacenter GPUs for AI training.
