InfiniBand defines an input/output architecture that can connect servers, communications infrastructure equipment, storage and embedded systems. It can achieve very high data transfers up to 120GB/s over copper and optical fiber connections, with the benefits of low latency and only requiring a low processing overhead. It is used in many data centers, high-performance computer clusters, connecting supercomputers, and in embedded applications that scale from two nodes up to a single cluster that interconnects thousands of nodes.
