An input/output architecture used in high-end computer clusters and storage networks, 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 as a true fabric architecture that can extend connections via external networks. Speed is 2.5 Gbps in each direction, and channels can be bonded to double and quadruple the data path to 5 and 10 Gbps.

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.

A futures broker who has a direct relationship with a client, but delegates the work of the floor operation and trade execution to another futures merchant. The merchant firm is usually a close partner of the IB.

Investopedia Says:
This is done to increase efficiency and lower the work load for futures brokers. It allows the IB to focus on the client while the futures merchant focuses on trading floor operations.
