InfiniBand is a type of communications link for data flow between processors and I/O devices that offers throughput of up to 2.5 gigabytes per second and support for up to 64,000 addressable devices. Because it is also scalable and supports quality of service (QoS) and failover, InfiniBand is often used as a server connect in high-performance computing (HPC) environments. The internal data flow system in most PCs and server systems is inflexible and relatively slow. As the amount of data coming into and flowing between components in the computer increases, the existing bus system becomes a bottleneck. Instead of sending data in parallel (typically 32 bits at a time, but in some computers 64 bits) across the backplane
