The Problem

AI factories don't stall on GPUs. They stall on the network.

A neocloud building an AI factory has to assemble power, cooling, structured cabling, optical interconnect, open switches, AI fabric software, cluster management, and network intelligence — each from a different specialist.

"Integration debt" — months managing 10+ vendors before the first GPU collective even runs.

Each vendor optimizes for their own layer. None integrate the whole. The result: mismatched delivery schedules, validation rework, and finger-pointing when something doesn't talk to something else.

Without a VAD doing the work for you

  • 10+ separate vendor relationships per build phase
  • Optical supply chain risk at neocloud volumes
  • Fabric OS lock-in or DIY SONiC integration
  • No software intelligence above the fabric
  • Power, cooling, OOB out of scope
  • Cabling design and labelling done in-house
  • Onsite install at five different timelines
The Validated Stack

The Full Ecosystem. Eight layers. One commercial relationship.

Every layer of the sovereign data center networking stack — from in-rack DAC to network intelligence — supplied, validated, and delivered through a single EPS Global engagement.

~800–900 Coherent optics and AOC per POD — the single largest line in the BoM by unit count, reflecting why a 25-year authorized Coherent partnership is the anchor of this stack. Plus 2× Vertiv rPDUs per rack, in-rack CDU 121 cooling, and Avocent ACS8000 OOB management.
Challenges & Solutions

Six points of friction. One bundle that closes them.

Challenge

10+ vendors per build phase. Mismatched delivery dates. Months of integration work before the cluster lights up.

→

Solution

One validated stack, one PO, one account team. EPS Global pre-sales engineering sizes the BoM and handles vendor coordination.

Challenge

Optical supply chain risk at neocloud volumes — and ~800 transceivers per POD means optics is your #1 line item.

→

Solution

25-year authorized Coherent partnership. Volume terms, roadmap visibility, and full reach coverage from in-rack to ZR+ metro.

Challenge

Picking a fabric OS without locking yourself into a single vendor or rolling your own SONiC distribution.

→

Solution

Validated choice between Hedgehog and Aviz Networks — both running on Celestica hardware, both integrated with Maia Edge above.

Challenge

Hardware-only VADs leave the AI workload intelligence layer empty. RoCE, GPU collective routing, traffic engineering — your problem.

→

Solution

Maia Edge for AI cluster fabric management. Aria Networks for SDN analytics and capacity planning. Both new strategic EPS Global relationships.

Challenge

Power, cooling, racks, and out-of-band management sit in someone else's scope — until they don't, and your install slips.

→

Solution

Vertiv closes the physical loop: PowerIT rPDUs to 150kW, CoolChip in-rack CDUs, Great Lakes enclosures, Avocent OOB — all on the same EPS Global PO.

Challenge

Cable design, custom labelling, and onsite install across multiple regions — typically the longest pole in the deployment tent.

→

Solution

Proficium handles 3D design, pre-labelled cable manufacturing, and onsite install — claimed 5× faster than traditional approaches.

The EPS Global Edge

What a hardware-only distributor can't do for you.

EPS Global is a value-added distributor — not a box-mover. The neocloud stack is assembled, validated, and delivered as a single engagement.

Optical anchor depth

Twenty-five years of authorized Coherent distribution. Volume pricing and supply chain depth that general distributors cannot match — critical when optics is ~800 units per POD.

Strategic software layer

Maia Edge and Aria Networks are new EPS Global relationships at the AI cluster management and network intelligence layers — differentiation no hardware-only VAD can replicate.

Choice, not lock-in

Hedgehog or Aviz Networks for the SONiC fabric OS — both validated on Celestica hardware. EPS Global engineering advises on the right fit for your operations model.

Complete physical infrastructure

Vertiv closes power, cooling, rack enclosures, and OOB management within the same EPS Global engagement. Amphenol covers DAC and structured fibre.

Professional services wrapped in

Proficium provides infrastructure design, custom cable manufacturing, and global install. Their BoM flows directly into EPS Global procurement.

Global fulfilment

28 EPS Global stocking locations across Europe, North America, and Asia Pacific support initial POD builds and ongoing replenishment of optics, AOC, PDUs, and cabling.

Frequently Asked Questions

Common questions from sovereign data center operators.

Nine validated partner technologies across eight infrastructure layers — Coherent (optics & AOC, anchor relationship), Celestica (open switches), Hedgehog or Aviz Networks (SONiC fabric OS), Maia Edge (AI cluster management), Aria Networks (network intelligence), Amphenol (DAC and structured cabling), Vertiv (power, cooling, rack, OOB), and Proficium (design and install services). All assembled, validated, and delivered through a single EPS Global engagement.
Yes. Both are validated on Celestica hardware and both integrate with Maia Edge as the AI workload management layer above. Aviz adds richer day-2 operations and multi-tenant GPU orchestration that suit GPU-as-a-Service models. Hedgehog is purpose-built for open networking automation in AI cluster fabrics. EPS Global pre-sales engineering will advise on the right fit for your operational model.
Direct procurement means 9+ separate commercial relationships, separate stocking arrangements, and integration validation done in-house. The EPS Global engagement consolidates this into one PO, one account team, validated layer-to-layer interoperability, and access to volume terms — particularly on the Coherent optics line, which is typically the largest single line item in a POD BoM.
Lead time varies by topology, fabric OS choice, and stocking position at the time of order. Our pre-sales team typically scopes a delivery window during the BoM consultation. Coherent stocking depth across 28 EPS Global locations and Proficium pre-labelled cable manufacturing materially compress the critical path versus a multi-vendor direct procurement.
Yes. The 1,024-GPU POD reference is a starting template, not a constraint. EPS Global pre-sales engineering and Proficium design services size the topology, oversubscription ratio, NIC density, optical reach mix, and rack power density to your specific deployment. Both Hedgehog and Aviz support custom fabric configurations, and Maia Edge / Aria Networks scale across larger fabric domains.
EPS Global operates 28 stocking locations across Europe, North America, and Asia Pacific, supporting both initial POD builds and ongoing replenishment of optics, AOC, PDUs, and cabling. Proficium provides global onsite installation services. Specific regional capabilities can be confirmed during the consultation — particularly relevant for tariff, customs, and lead-time planning.
