Every Spacebus site is built from the same repeatable design: a self-contained cluster with its own power, cooling, and compute — engineered so that adding sites means replicating a proven design, not re-solving infrastructure from scratch each time.
Four systems, engineered together, repeated identically at every location in the network.
Spacebus sites run on current-generation GB300 NVL72 clusters, purpose-built for large-scale inference and training workloads at rack-scale density.
Next-generation platforms — including NVIDIA Vera Rubin and Groq LPx — are treated as a roadmap upgrade into the same physical footprint, not a separate build. Sites are designed from day one to absorb the next hardware generation rather than be stranded by it.
Every site uses closed-loop thermal management with no ongoing water draw. That removes local water availability as a siting constraint and eliminates a growing source of community and regulatory friction around data center growth.
Conventional evaporative cooling ties data center growth to local water systems. A water-zero design means Spacebus can site capacity in more places, including markets where water stress would otherwise rule out new construction.
Every site is built on fully redundant, 2N power infrastructure — no single point of failure between the grid and the GPU.
Each site pairs grid power with owned, onsite solar generation, reducing dependence on grid interconnection timelines and easing the demand each site places on the local grid.
Every site connects out on fully redundant, 2N 400GbE fiber links — no single point of failure between the cluster and the network, matching the same redundancy standard applied to power.
High-bandwidth, low-latency connectivity keeps inference traffic moving as fast as the GPUs can serve it, so the network is never the bottleneck between a request and a response.
The core of the Spacebus model: a standardized build process that takes a site from control to live workloads in 90 days.
Site secured and power interconnection agreements finalized alongside local utility and permitting partners.
Prefabricated power, cooling, and enclosure modules installed on a standardized design — minimizing on-site custom construction.
GPU clusters installed, networked, and validated against performance and redundancy benchmarks.
Contracted customer workloads onboarded and live — typically within 90 days of site control.
Built to meet the assurance requirements of regulated and public-sector customers as the network scales.
