The hardware that makes
a hub credible.

The default GPU at every ARO site is the NVIDIA RTX PRO 6000 Blackwell, 96 GB of GDDR7 memory and native FP4 precision. That combination is the difference between needing two H100s to run a 70B-parameter model and running it on a single card with KV-cache headroom to spare.

For tenants whose workload profile leans toward training or distributed multi-node clusters, anchor sites can be specified with NVIDIA H100 or H200 nodes. H200 brings 141 GB of HBM3e per GPU and roughly twice the memory bandwidth of an H100, useful for very-large-context inference or fine-tuning.

Inside each rack, GPUs are wired together over NVLink high-speed fabric for low-latency tensor sharding. Outside the rack, every node has a 100 GbE backhaul path to the property's fiber demarc.

What you can run

• Production LLM inference, 7B to 70B parameter models on a single Blackwell card; larger model parallelism across the rack.
• Multi-modal & vision, image, video, and audio inference workloads with bandwidth headroom.
• Fine-tuning & LoRA, tenant-specific model adaptation on isolated nodes.
• Distributed training at anchor sites with H100/H200 NVLink-fabric configurations.

Modern AI racks push 100–140 kW. That density isn't survivable on air alone. Standard ARO hub cooling is the Motivair M16 rear-door heat exchanger, a passive plate at the back of each rack fed by a 55–65°F facility water loop. Heat leaves the IT loop in sensible exchange to the rear-door coil; no condensation, no air handlers in the room.

For high-density configurations, we offer a liquid immersion cooling option, racks submerged in dielectric coolant, near-silent operation, and density well beyond what rear-door alone can carry.

Power profile

• 415V 3-phase electrical service per rack, six IEC 309 60A 3P+N+E connections.
• UPS-backed with site-specific runtime targets.
• Behind-the-meter generation or microgrid integration at qualified sites, valuable where utility queue times are blocking grid-tied AI capacity.
• Sub-meter on the property's electrical service so utility consumption is reimbursed cleanly.

Water profile (rear-door cooling)

• Closed loop, 55–65°F supply temperature.
• Coolant chemistry within published Motivair limits (chloride, calcium, magnesium, sulfate ≤ 25 ppm; pH 7–10.5).
• 50-mesh inline filtration in the closed loop.
• Total water draw is per-site; we share specifics during the design pass.
