InfiniBand Networking Fundamentals for High-Performance Computing

High-performance computing, artificial intelligence workloads, and modern data centers rely on ultra-low latency and massive throughput to function efficiently. Understanding how to configure and manage InfiniBand networks is a critical skill for systems administrators and network engineers working in these cutting-edge environments. This text-based course guides you from foundational networking concepts to practical administration strategies. You will transition from a general understanding of standard networking to a detailed command of high-performance fabric management, enabling you to optimize cluster communications. You will learn to: - Understand InfiniBand architecture, terminology, and how it differs from traditional Ethernet - Identify and configure key physical components including Host Channel Adapters, switches, and cables - Configure and manage the Subnet Manager to control fabric routing and initialization - Implement partition keys and security policies to isolate and protect cluster traffic - Monitor fabric health and troubleshoot link errors using standard command-line diagnostic tools - Explore modern integration patterns including RoCE (RDMA over Converged Ethernet) and virtualization This course begins with a thorough introduction to basic high-performance clustering terms and architectural layers before moving into configuration files and diagnostic commands. Through clear, written explanations and structured examples, you will build a solid working knowledge of fabric administration. This course is designed for beginner-level network administrators, systems engineers, and IT professionals who want to understand high-speed fabrics. No prior experience with InfiniBand is required, though a basic understanding of general networking concepts is helpful.
