InfiniBand and High-Speed Ethernet for Dummies

SESSION: InfiniBand and High-Speed Ethernet for Dummies

EVENT TYPE: Tutorials

EVENT TAG(S): Architectures, Clouds and Distributed Computing, Networks

TIME: 8:30AM - 12:00PM

Presenter(s):Dhabaleswar K. (DK) Panda, Hari Subramoni, Khaled Hamidouche



InfiniBand (IB) and High-speed Ethernet (HSE) technologies are generating a lot of excitement towards building next generation High-End Computing (HEC) systems including clusters, datacenters, file systems, storage, cloud computing and Big Data (Hadoop, Spark, HBase and Memcached) environments. RDMA over Converged Enhanced Ethernet (RoCE) technology is also emerging. This tutorial will provide an overview of these emerging technologies, their offered architectural features, their current market standing, and their suitability for designing HEC systems. It will start with a brief overview of IB and HSE. In-depth overview of the architectural features of IB and HSE (including iWARP and RoCE), their similarities and differences, and the associated protocols will be presented. An overview of the emerging Omni-Path architecture will be provided. Next, an overview of the OpenFabrics stack which encapsulates IB, HSE and RoCE (v1/v2) in a unified manner will be presented. An overview of libfabrics stack will also be provided. Hardware/software solutions and the market trends behind IB, HSE and RoCE will be highlighted. Finally, sample performance numbers of these technologies and protocols for different environments will be presented.
