InfiniBand Network Architecture
InfiniBand utilizes high-speed serial technology to interconnect data center elements. Each link consists of a signal pair that transfers information in both directions simultaneously at 2.5Gb/s. To increase throughput even more, four or twelve pairs can be implemented, yielding transfer rates of 312.5MB/s, 12.5GB/s, or 37.5GB/s.
Unlike other networking technologies, InfiniBand permits local and remote application software entities to perform memory-to-memory transfers without the intervention of the processor. This frees up most of the processor’s bandwidth to deal with computational problems. The architecture provides increased reliability, better sharing of data, and built-in security. InfiniBand Network Architecture provides a detailed description of this networking technology from both the hardware and software perspective.
