InfiniBand is a high-speed, low-latency, high-bandwidth input/output (I/O) communication architecture designed for computer clusters and other parallel computing environments. It provides a switched fabric architecture that enables communication between processors, memory, and I/O subsystems. InfiniBand is used in high-performance computing (HPC) environments such as data centers, supercomputers, and high-speed storage networks, as well as in applications such as database clustering, grid computing, and digital content creation.
