DriveNets, WhiteFiber and WEKA successfully connected GPU clusters at two geographically separated data centers to operate as one AI supercluster. The video explores how this scale-across approach helps overcome power and capacity constraints, alongside network planning considerations and plans to expand to more sites.

𝗞𝗲𝘆 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆𝘀

•  Plan the network ahead: use shallow buffer for intra-site connectivity and deep buffer for cross-site connectivity.
•  Provide sufficient capacity, preferably dark fiber, between the sites, and use a scheduler that spreads the workload across different systems.
•   • When a data center runs out of power, add GPUs in another data center up to 50 and even 100 miles away. Both GPU clusters then work as a single cluster.
•   For latency-sensitive inference, place GPUs closer to customers at the edge, and measure time to first token and time between tokens, not just round-trip delay.
•   WhiteFiber runs 2 sites today and plans 3 or more in a mesh or hub-and-spoke model, combining smaller modular capacity into one larger fabric.

At the AI Infra Summit, DriveNets’ Dudy Cohen (VP Product Marketing) explores how networking plays a key role in AI infrastructure, from optimizing GPU utilization, supporting scale-across for data centers to enabling heterogeneous AI.

What will you learn:

• How networking helps optimize GPU utilization and improve tokens per dollar and per watt.
• Why full-stack optimization spans switches, NICs, communication libraries, and workloads.
• How networking enables heterogeneous AI clusters with different GPU and ASIC types.
• Why disaggregated inference requires networks that handle bursty traffic and KV cache transfers.
• How scale-across connects GPUs across geographically separated data centers to tap into available power resources.

Nasdaq Marketsite reporter Kristina Ayanian interviews DriveNets CEO & co-founder, Ido Susan, and Hillel Kobrinsky, Chief Strategy Officer and co-founder.

DriveNets Co-Founder and CEO Ido Susan and Co-Founder and Chief Strategy Officer Hillel Kobrinsky joined Kristina Ayanian at Nasdaq MarketSite to discuss DriveNets’ $410 million Series D funding round, the company’s growth, and the future of AI infrastructure.

In the interview, they explained why the round is not a traditional fundraising milestone, but a “delivery round” designed to support DriveNets' scaling inventory, supply chain, and customer delivery.

They also covered AMD’s role as a strategic investor, the market shift toward open, multi-vendor AI infrastructure, and why network performance has become critical to maximizing GPU utilization.

DriveNets is helping to solve AI networking bottlenecks by optimizing the software stack connecting tens of thousands of GPUs into a single high-performance infrastructure. Discussing the rise of heterogeneous AI, they expand on how different AI workloads should be matched to the most suitable chips, resources, and architectures.

Dudy Cohen, VP of Product Marketing at DriveNets, examines the rapid evolution of Ethernet technology and its critical role in AI infrastructure. Cohen discusses how Ethernet is advancing through multiple dimensions—from 800G to 1.6T line rates, co-packaged optics integration, and the introduction of scheduling layers that address Ethernet's traditional limitations. He explores the dramatic scaling of GPU clusters, from thousands to potentially millions of units, and explains why different scheduling approaches—fabric scheduling versus endpoint scheduling—suit different deployment scenarios.

Cohen traces DriveNets' journey from building scalable service provider routers to applying the same scheduled fabric technology to AI backend networks. The discussion reveals how technical architecture choices directly impact business metrics, from time to first token to cost per million tokens, and why open, Ethernet-based solutions are gaining traction across hyperscalers, neoclouds, and enterprise deployments.

What You Will Learn:

• How Ethernet technology is evolving across speed, optics, and scheduling capabilities
• The difference between fabric scheduling and endpoint scheduling for AI networks
• Why ESUN technology enables Ethernet to compete with purpose-built scale-up protocols
• How GPU cluster sizes are scaling from thousands to potentially millions of units
• The business case for Ethernet-based AI infrastructure in terms of deployment speed and operational costs

From the SuperCompute25 event in St. Louis, this episode takes a look behind the scenes of the world’s largest temporary network. Hear about the real challenges of orchestrating massive, multi-vendor networks—and how a new platform aims to simplify network operations end to end, with big news coming in 2026.

In this episode of CloudNets, we dive into the last-mile redundancy dilemma for service providers. We explore the trade-offs between single and dual connections, the complexity of traditional chassis-based designs, and how Distributed Disaggregated Chassis (DDC) delivers the best of both worlds—true redundancy, resilience, and scalability without added operational complexity.
