BE Networks and NVIDIA Partner to Automate GPU Farms with Spectrum-X Ethernet
Today we are proud to share with the public our strategic partnership with NVIDIA to bring a new level of automation and operational efficiency to GPU farm networking. By integrating BE’s Verity software platform with NVIDIA’s Spectrum-X Ethernet switches and Cumulus Linux, the two companies are enabling operators to stand up and manage high performance Ethernet fabrics with precision and reliability from day zero provisioning through daily operations.
Meeting the Demands of Modern GPU Farms
In the last decade, the growth of GPU accelerated computing has reshaped data centers. Training large scale AI models and running inference pipelines require clusters with thousands of GPUs operating at peak efficiency. The compute side of the equation has advanced rapidly, but the network fabric tying these GPUs together has often been the bottleneck.
Traditional manual provisioning methods or fragmented automation approaches cannot keep pace with the performance requirements or the scale of GPU farms built on Spectrum-X Ethernet. Operators need deterministic outcomes, predictable performance, and a way to reduce operational risk. The partnership between BE Networks and NVIDIA directly addresses these needs.
“Spectrum-X Ethernet was built to deliver lossless Ethernet optimized for AI workloads. By integrating with BE Verity, we are making it easier than ever for Enterprise customers to deploy and operate these fabrics without having the need for large, on-site and highly skilled NetOps team.”
The Role of Spectrum-X Ethernet and Cumulus Linux
NVIDIA Spectrum-X Ethernet switches have set the standard for ultra-low latency and lossless networking in GPU farms. They provide predictable throughput, congestion control, and optimized data paths for AI workloads. When combined with Cumulus Linux, operators gain the flexibility of a modern network operating system while retaining the deterministic forwarding behavior required for AI clusters.
However, operating these fabrics at scale is not trivial. A typical GPU farm can include hundreds of leaf and spine switches, with requirements for precise queue management, ECN configuration, and traffic engineering. Any misstep in provisioning or ongoing configuration can create congestion hotspots that cripple GPU efficiency. This is where BE Networks’ Verity software steps in.
BE Verity: Automation Built for Ethernet Fabrics
Verity was built by engineers who have spent decades designing, deploying, and troubleshooting large scale Ethernet networks. The platform automates the entire lifecycle of the fabric. From zero touch provisioning of new Spectrum-X Ethernet switches to day two operations such as monitoring, upgrades, and policy changes, Verity eliminates manual steps and reduces human error.
Key features of Verity include:
- ZTP-based onboarding: New switches can be racked, powered on, and automatically provisioned with the correct Cumulus Linux image, configurations, and policies.
- Deterministic fabric provisioning: Verity enforces topology aware configuration, ensuring that every link, port, and queue is set up correctly.
- Closed loop validation: The software constantly validates that the running state of the fabric matches the intended state, closing the gap between design and operations.
- Integrated telemetry: With our integrated Observability platform – Satori, real time fabric health monitoring gives engineers visibility into latency, buffer utilization, and congestion events.

Using NVIDIA Air, customers can easily learn how to use Verity as well as perform complex network simulations including digital twins, automation workflows, config rendering, and hardware evaluation.
Why Automation Matters for AI Networking
In GPU farms, networking is not just plumbing. It is a performance multiplier. A congestion event on a single switch can slow down a training job that spans thousands of GPUs, wasting compute cycles that cost millions of dollars per week. The economics of AI make automation essential.
Manual CLI-based provisioning does not scale. Scripting can help but often introduces complexity and fragility. What is required is a purpose-built automation platform that understands the nuances of Ethernet fabrics and is tightly integrated with the underlying hardware and operating system. Verity was designed for exactly this role.
A Partnership Built on Real Engineering
The collaboration between NVIDIA and BE Networks is more than a marketing announcement. Engineers from both companies have worked side by side to ensure that Verity can take full advantage of the capabilities of Spectrum-X Ethernet and Cumulus Linux.

Founder & CEO, BE Networks
Through joint testing in large scale GPU farm environments, Verity has demonstrated that it can automate fabrics spanning thousands of ports while maintaining the deterministic performance Spectrum-X Ethernet is known for. Operators can now deploy AI clusters faster, with less risk, and with greater confidence in long term stability.
Operational Impact for Customers
As GPU farms continue to scale, the need for automation will only grow. BE Networks and NVIDIA are committed to expanding the capabilities of Verity and Spectrum-X Ethernet to handle larger fabrics, more complex topologies, and tighter integration with AI frameworks.
Future roadmap items include enhanced telemetry integration with NVIDIA’s AI software stack, as well as expanded support for hybrid topologies that combine Ethernet and InfiniBand. The partnership is designed to evolve with customer needs and the rapid pace of AI innovation.
Conclusion
The partnership between BE Networks and NVIDIA represents a significant milestone for AI networking. By combining Spectrum-X Ethernet switches, Cumulus Linux, and BE’s Verity automation software, operators of GPU farms can now provision and manage their fabrics with unprecedented speed, reliability, and confidence.
For network engineers who have spent years managing complex data center fabrics, this collaboration feels like a turning point. Instead of patchwork scripts and manual troubleshooting, we now have an integrated, battle-tested solution that reflects the way networks should be built and operated.
The future of AI will be defined not only by GPUs but by the networks that connect them. With NVIDIA and BE Networks working together, that future just became more predictable, more efficient, and more attainable.
