What we do.

Big3 Energy plans, builds and turns on the AI compute stacks that power large data center operators — architecture, deployment and day-two operations, owned end to end.

01 · Services

Four disciplines. One accountable partner.

Service 01

Architecture & Planning

We translate GPU-hungry workloads into a buildable, bankable data center design.

  • Workload & density modeling
  • NVIDIA reference architecture selection
  • Power, cooling & network engineering
  • Site feasibility & capacity audits
Service 02

Deployment & Commissioning

From shipping crates to a validated, production-ready cluster — on schedule.

  • Rack-and-stack & cable management
  • NVLink / InfiniBand fabric bring-up
  • Driver, firmware & microcode baseline
  • 24-hour stress & burn-in validation
Service 03

Power & Cooling Systems

AI density breaks conventional facilities — we engineer the infrastructure that keeps up.

  • Direct-to-chip liquid loop design
  • 415V / 48V power distribution planning
  • Redundancy & uptime engineering
  • Thermal modeling at rack density
Service 04

Operations & Optimization

Post-cutover, we make sure every GPU earns its keep.

  • Cluster monitoring & alerting
  • Job orchestration — SLURM / Kubernetes
  • GPU utilization & cost optimization
  • Runbooks, docs & team training

02 · The Stack

Top to bottom, we deliver every layer.

A Big3 deployment is designed as a single system: applications, software, compute, fabric, and the power and cooling that keep them alive.

01 Applications & Orchestration SLURM · KUBERNETES · MLFLOW 02 Software Stack CUDA · NCCL · CUDA-X · TENSORRT 03 Compute Nodes GB200 NVL72 · B200 · H200 · GRACE BIG3 · CORE FOCUS 04 Fabric & Network NVSWITCH · NVLINK DOMAINS · 800G IB / ROCE 05 Power & Cooling DIRECT LIQUID COOLING · 415V PDU · UPS

NVIDIA-NATIVE REFERENCE STACK — ONE PARTNER, EVERY LAYER

03 · Engagement Model

A delivery pipeline built for new-build scale.

S1

Survey

Walk the site — power, cooling, network capacity

S2

Design

Lock the reference architecture & bill of materials

S3

Deploy

Build and cable the cluster to spec

S4

Validate

Stress-test fabric, thermals & throughput

S5

Handover

Docs, runbooks & engineer-to-engineer training

S6

Optimize

Continuous utilization & cost tuning

04 · Why Big3 Energy

Built by people who have done this at scale.

AI workloads punish every mistake in the stack — from a single bent fiber to a miscalculated thermal envelope. Big3's engineers come from large-scale HPC and data center delivery, and it shows in the uptime.

  • NVIDIA-native expertise across DGX, HGX & GB200 platforms
  • Vendor-agnostic procurement oversight and lead-time management
  • Turnkey delivery — one contract from blueprint to bare metal
  • Designed for multi-megawatt, GPU-dense facilities
big3 — principles
01 / design for density, not convenience 02 / fabric validated before first job 03 / thermals modeled, not assumed 04 / every rack cabled to spec 05 / handover = runbooks + humans

Scope your build

Let's put your next cluster on the critical path.

Whether it's a pilot rack or a multi-megawatt hall, the first conversation is free.
