Talk: RDMA at Hyperscale: Experience and Future Directions

Abstract: Remote Direct Memory Access (RDMA) has long been recognized as a powerful technology for high-performance computing and data-intensive applications. In this talk, I will present our experience in deploying intra-region RDMA to support storage workloads in Azure. Today, around 70% of traffic in Azure is RDMA and intra-region RDMA is supported in all Azure public regions. I will also discuss some open problems we see going forward and our early efforts in these directions.
