Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
Microsoft Azure's ND H200 v5 cluster, entered in the November 2024 TOP500 at rank 32 with 45.59 PFlop/s Rmax and still listed at rank 57 in June 2026. Microsoft Learn describes the ND H200 v5 VM as eight H200 GPUs with 96 Sapphire Rapids vCPUs and a dedicated 400 Gb/s Quantum-2 InfiniBand link per GPU, and TOP500 lists Xeon Platinum 8480C hosts with NDR InfiniBand. No datacentre or power figure is published, so the site follows the undisclosed convention used for Eagle.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
| Cited source | Result | Found on the page |
|---|---|---|
| learn.microsoft.com | does not name this system | NVIDIA H200 SXM, Intel Xeon Platinum 8480C, NVIDIA InfiniBand NDR (Quantum-2) |
| top500.org | names system and part | NVIDIA H200 SXM, Intel Xeon Platinum 8480C, NVIDIA InfiniBand NDR (Quantum-2), Ubuntu Server |
