Claims

An NVL72 rack involving Dell, CoreWeave, and Nvidia has successfully passed L11 diagnostics.
Passing L11 diags confirms that IMEX channels on the NVL72 scale-up domain within the rack are operational.
The system is not yet a full cluster because scale-out networking has not been configured.

Key quotes

Notably, passing L11 diags means that this rack is up and running, including the IMEX channels on the NVL72 scale-up domain within the rack! Not a full cluster, since there is no scale-out networking setup yet, but still quite the flex from Mr. Dell, CoreWeave, and NVIDIA.
