CloudNets S5 E4 Last Mile Redundancy Dilemma

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.𝗥𝗲𝗮𝗱 𝘁𝗵𝗲 𝗳𝘂𝗹𝗹 𝘀𝘁𝗼𝗿𝘆https://www.whitefiber.com/blog/cross-data-center-networking-solution---------------------------------------------------------------------𝗟𝗲𝗮𝗿𝗻 𝗺𝗼𝗿𝗲 𝗮𝗯𝗼𝘂𝘁 𝗗𝗿𝗶𝘃𝗲𝗡𝗲𝘁𝘀https://drivenets.com/DriveNets builds high-performance networking solutions for large-scale AI infrastructure and service-provider networks.

Discussing the rise of heterogeneous AI, they expand on how different AI workloads should be matched to the most suitable chips, resources, and architectures.𝗪𝗵𝗲𝗿𝗲 𝘁𝗼 𝗳𝗶𝗻𝗱 𝗗𝗿𝗶𝘃𝗲𝗡𝗲𝘁𝘀🔗 LinkedIn: https://www.linkedin.com/company/drivenets        🔗 X:   https://x.com/drivenets𝗣𝗼𝗱𝗰𝗮𝘀𝘁𝘀🔈 Apple:  https://podcasts.apple.com/il/podcast/cloudnets/id1589786423🔈 Spotify:  https://open.spotify.com/show/1q8e4hNOyaz5ySTeRjTP25👇SUBSCRIBE TO OUR NEWSLETTER NOW👇Subscribe on LinkedIn https://www.linkedin.com/build-relation/newsletter-follow?entityUrn=6953575364468056064

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 capabilitiesThe difference between fabric scheduling and endpoint scheduling for AI networksWhy ESUN technology enables Ethernet to compete with purpose-built scale-up protocolsHow GPU cluster sizes are scaling from thousands to potentially millions of unitsThe business case for Ethernet-based AI infrastructure in terms of deployment speed and operational costs
