Derive a 16-leaf, 8-spine fabric from 512 endpoints, trace local and cross-leaf routes, and check what rail placement and oversubscription actually guarantee.

Diagnose failed 800G links using endpoint compatibility, lane modes, inventory and controlled swaps. Learn why speed labels and failure patterns do not prove a cause.

Localize a slow fabric rail with matched tests, path comparisons and counter deltas. Separate an independent-bandwidth sum from collective completion time.

Compare complete fabric proposals on workload performance, support and total cost. Translate any measured regression into application impact before pricing the discount.

Choose between supported InfiniBand and RoCE designs using workload tests, congestion behavior and a complete cost model.

Follow expert assignments from logical payload to off-rank and cross-node traffic. Compare dispatch and combine dtypes, receiver skew and local-domain placement.
