InfiniBand: Overview, Working, Installation & Configuration 1. What is InfiniBand? InfiniBand (IB) is a high-speed, low-latency networking technology designed for HPC (High-Performance Computing), AI, and data centers . It provides high bandwidth (up to 800 Gbps with NDR InfiniBand) and is commonly used in supercomputers and clusters . 2. How InfiniBand Works? InfiniBand creates a switched fabric topology, where each node (compute or storage) is connected via InfiniBand switches . Unlike traditional Ethernet, IB uses RDMA (Remote Direct Memory Access) , allowing direct memory access between nodes without CPU involvement . Key Features of InfiniBand: ✅ High Bandwidth (up to 800 Gbps with latest versions). ✅ Low Latency (sub-microsecond). ✅ RDMA Support (direct memory access, reducing CPU load). ✅ Lossless Networking (no packet drops like Ethernet). ✅ Supports Multi-Pathing for better reliability. 3.
