Dell and Supermicro were both reported as server suppliers for xAI’s planned Grok-focused compute project in Memphis, Tennessee. A June 20, 2024 report confirmed both companies’ involvement but did not disclose how the GPU clusters would be divided between them. Later Supermicro-hosted case-study material documents hardware used for the Colossus cluster; it should not be treated as a complete specification for every xAI site.
Who is building Grok’s AI compute factory?
Data Center Dynamics reported on June 20, 2024, that Dell and Supermicro would provide servers for xAI’s supercomputer project in Memphis. The story linked the project to xAI’s effort to build a “gigafactory of compute.” Michael Dell, Dell chairman and CEO, described it in a post reproduced in the report: “We’re building a Dell AI factory with @nvidia to power @grok for @xai @elonmusk.” Elon Musk also confirmed Supermicro’s involvement. Data Center Dynamics’ June 20, 2024 report did not say which supplier would provide which GPU clusters, or how much work each company would handle.
What hardware is documented for the Colossus cluster?
Supermicro’s later Colossus materials describe a particular xAI cluster implementation, not a universal configuration for the Memphis project or all xAI facilities. The vendor feature page identifies Colossus as a 100,000-GPU cluster and describes liquid cooling. Supermicro’s Colossus feature page and a December 2024 ServeTheHome case study hosted by Supermicro provide the concrete details:

- Cooling: Liquid-cooled racks.
- Rack layout: Eight 4U servers and 64 GPUs per rack, according to the case study.
- Build time: The case study says the teams built the cluster in 122 days. Its account states, “In only 122 days, the teams built this giant cluster.”
Those figures are specific to the Colossus case study. They do not establish the configuration of Dell’s contribution, the supplier allocation across the original project, or hardware used at later xAI sites.

How does the Memphis project relate to later xAI facilities?
The June 2024 supplier report concerned a project described as being in Memphis, Tennessee. Later reporting covers separate expansion in the greater Memphis area, so the sites and stages should not be collapsed into one facility. The Associated Press reported on regional expansion and a planned xAI data center in Southaven, Mississippi. In January 2026, AP reported xAI’s announcement of a $20 billion Southaven project and quoted xAI’s CFO describing a planned cluster with 2 gigawatts of computing power. Those are announcement claims, not a measurement confirming an operating facility. AP’s report on regional expansion and its January 2026 Southaven report describe this later context.

The June 2024 report establishes that Dell and Supermicro were both named as server suppliers, but it does not identify their respective GPU-cluster assignments or provide a complete division of equipment. The available Colossus case-study details cannot fill that gap: they describe one cluster and do not amount to a full supplier inventory for xAI’s subsequent facilities.

Dell also describes an enterprise offering to bring Grok models on-premises, but that is a separate deployment offering rather than evidence about Dell’s server allocation for xAI’s own compute project. Dell’s enterprise announcement covers that distinct use case.
