InfiniBand is an interconnect technology that breaks through the bandwidth and fanout limitations of PCI bus by switching from traditional shared bus architecture to a switched fabric architecture. It is a switched fabric I/O technology that ties together servers, storage devices, and network devices. Instead of sending data in parallel, which is what PCI does, InfiniBand sends data in serial and can carry multiple channels of data at the same time in a multiplexing signal.

IBM® AIX® 610 supports InfiniBand hardware and various protocols that run over InfiniBand. This article shows how to configure InfiniBand and set up IP over InfiniBand interface (IPoIB) in AIX. Also, this article explains how to use RDS (Reliable Datagram Sockets), a protocol (similar to UDP) designed to work over InfiniBand to send and receive data using sockets.
