This is how you know this guy is a clueless bear. He can't even come up with good lies. ZT Systems have some of the most experienced rack engineers. Every time the stock rallies you can bet it attracts a lot of bears.
ZTS racks and known customers before acquisition:
| Platform before acquisition | When documented | ZT Systems' role | Source |
|---|---|---|---|
| **NVIDIA GB200 / ZT ACX200** | June 2024 | Announced a complete liquid-cooled rack platform integrating Grace CPUs, Blackwell GPUs, NVLink switch trays, specialized cabling and rack-level cooling. The clearest named example of its full-rack AI expertise. | [ZT announcement](https://ztsystems.com/zt-systems-announces-acx200-solutions/) |
| **NVIDIA DGX GH200** | May 2023 | Supplied the compute pods for NVIDIA's 256-Grace-Hopper supercomputer. ZT's role was identified during NVIDIA's Computex presentation. | [Computex coverage](https://www.servethehome.com/nvidia-computex-2023-keynote-nvidia-dgx-gh200-mgx-and-spectrum-x-specturm-4-arm/) |
| **NVIDIA H100/H200 systems** | By August 2024 | Participated in the NVIDIA server supply chain with Inventec. Inventec confirmed existing H100, H200 and GB200 orders would continue following AMD's acquisition announcement. Customer-specific rack model names were not disclosed. | [Economic Daily News, quoting Inventec](https://money.udn.com/money/story/5612/8172313) |
| **AMD Instinct MI250X and MI300X systems** | Before August 2024 | AMD confirmed it had already collaborated with ZT on AI platforms for large cloud customers using these accelerators and EPYC CPUs. Specific customer rack configurations were not named. | [AMD acquisition-call transcript](https://stockanalysis.com/stocks/amd/transcripts/222757-m-a-announcement/) |
| **Microsoft Project Olympus / ZT XPO200** | 2017 onward | Earlier hyperscale server and rack-integration work. ZT's 2018 presentation covered rack power, management, cooling and GPU systems, including HGX-1. These were predecessors to modern integrated AI racks. | [ZT's OCP presentation](https://www.opencompute.org/files/ZT-OCP2018.pdf) |
**Publicly documented customers**
| CSP / hyperscaler | Evidence of relationship | Source |
|---|---|---|
| **Microsoft / Azure** | Identified as a ZT customer by Reuters; also had a public engineering relationship with ZT around Project Olympus. | [Reuters](https://www.reuters.com/technology/amds-49-bln-zt-systems-deal-faces-eu-antitrust-decision-by-march-12-2025-02-05/) |
| **Amazon / AWS** | Longstanding server customer. Reporting predates the acquisition by more than a decade; 2024 coverage also identified AWS in the Inventec/ZT supply chain. | [Wired](https://www.wired.com/2012/11/amazon-google-secret-servers/) / [Economic Daily News](https://money.udn.com/money/story/5612/8172313) |
| **Meta** | Explicitly identified as a ZT customer by Reuters. Meta is a hyperscaler operating its own infrastructure, rather than a public-cloud provider like AWS or Azure. | [Reuters](https://www.reuters.com/technology/amds-49-bln-zt-systems-deal-faces-eu-antitrust-decision-by-march-12-2025-02-05/) |
ZT kept many customer engagements confidential. This is not an exhaustive customer list, and the public sources do not establish which customer purchased each rack/platform above.
