InfiniBand serial switched fabric is an emerging technology noted for high-performance, low latency, scalability and low cost per port. Designed to solve issues inherent to large systems, this technology has been adopted by the high-performance computing (HPC) market and is gaining respect in the enterprise and embedded computing arenas. Before assuming that you must use the traditional non-blocking system architecture, measure your server performance. As server performance increases, more switches can be added to accommodate the increase in bandwidth.
