Cloud Native Theater | KubeVirt Summit: Breaking the Performance Barrier... Jian Li & Yves Weisser

This talk covers high-performance AI storage virtualization using KubeVirt, presented by Jian Li from SK Telecom and Yves Weisser from NetApp. The rapid growth of generative AI demands a robust infrastructure that merges the flexibility of virtualization with the performance of bare-metal systems. The speakers detail the optimization techniques implemented in SK Telecom's Petasus AI Cloud, which features over 1,000 NVIDIA Blackwell GPUs and a unique fast filesystem integration. They share empirical data from benchmarks that illustrate the performance improvements achieved by virtualizing Ethernet Fabrics and enabling Native NFS over RDMA, demonstrating how to effectively reduce the "virtualization tax" in GPU clusters for cloud-native deployments.
