Hosn Rack
A rack-scale starting scope for institution-wide workloads. Facility evidence, measured demand and acceptance requirements determine the architecture.
What Hosn Rack is
Hosn Rack is the rack-scale Hosn configuration for institution-wide workloads that require a dedicated GPU, storage and network design at the customer's site. Its final architecture is developed from workload evidence and a review of the intended facility.
Public configuration summary
| Configuration | Rack-scale GPU deployment |
|---|---|
| Intended scope | Institution-wide workloads |
| Model | Selected and validated during discovery |
| Data boundary | Customer site, with an air-gapped option |
| Capacity | Sized against workload and facility evidence |
| Integration | Defined in the delivery scope |
| Commercial terms | Written quotation and contract |
When Rack may fit
Rack may fit when measured demand calls for institution-wide concurrency, larger retrieval collections, redundancy, dedicated accelerators or model adaptation on approved local material. Each capability is scoped separately and is not implied by the configuration name alone.
If a department or several teams can meet their requirements without facility-grade infrastructure, Hosn Kernel or Hosn Tower may be the more proportionate design.
Facility and technical evidence
Power, cooling, rack space, storage, network segmentation and operational access are reviewed before a rack-scale design is proposed. The bill of materials follows that evidence. Hosn does not publish a universal GPU count or capacity figure because those figures depend on the selected models and workload.
Model serving and adaptation
Selected open model families can be evaluated for local inference. Adaptation or fine-tuning is included only where it is technically justified, permitted by the institution and stated in the delivery scope. Training data handling and resulting artefacts are defined in the same scope.
What a quotation confirms
A written quotation confirms the architecture, bill of materials, software, integrations, acceptance criteria, facility responsibilities, schedule, support and commercial terms. Rack pricing is not published because the design is configuration-specific.
