InfiniBand

A high-speed interface used to connect storage networks and computer clusters, introduced in 1999. Using switched, point-to-point channels similar to mainframes and also similar to PCI Express (switched version of PCI), InfiniBand is designed for fabric architectures interconnecting devices in local networks.

A Technology Merger
Supporting both copper wire and optical fibers and originally known as "System I/O," InfiniBand is a combination of Intel's NGIO (Next Generation I/O) and Future I/O from IBM, HP and Compaq. For more information, visit the InfiniBand Trade Association at www.infinibandta.org. See RDMA, PCI Express, NGIO and Future I/O.
