  • The Three Puzzles of AI Data Center Fabric (Scale-Up, Out, Across)

    In our last post, we discussed the story of the birth of Ultra Ethernet Transport (UTE), which emerged as an alternative to the sluggish TCP and cumbersome RoCEv2 to handle the explosive traffic of the AI era. However, many of you often ask, “The concept is great, but is this really a feasible technology? When will it be implemented in our data centers?” Global consulting group McKinsey &…

  • The Birth of Ultra Ethernet (UET) and Next-Generation AI Fabric

    When training AI models, networks are no longer mere pipes. In a collective communication environment where tens of thousands of GPUs exchange data, a single packet loss becomes a critical bottleneck that delays the entire Joint Training Completion (JCT). At last year’s HPE Discover Barcelona, HPE and VIAVI Solutions presented a remarkable demonstration signaling a fundamental transformation of Ethernet…
