A Brief History Future I/O (FIO) was being developed by IBM, Compaq Computer, Hewlett-Packard, 3Com, Adaptec, and Cisco. Next Generation I/O (NGIO) was being developed by Intel, Dell Computers, Sun, and others. FIO and NGIO were competing technologies Neither would “win” so they combined forces to form Serial I/O (SIO) which combined the best of both technologies The name SIO could not escape the powerful clutches of the Intel Marketing department and hence was renamed InfiniBand Architecture or IBA for short

What is InfiniBand? A technology used to interconnect processing nodes to I/O nodes to form a System Area Network Intended to be a replacement for PCI Heavily leverages best-of-breed technologies

The Problem The need for a cost-effective interconnect technology for building clusters. Bus-based architectures (i.e. PCI) are limited to a single host system and cannot easily extend beyond the confines of the “box”. Bandwidth and Latency between boxes using existing system area networks are limited and/or expensive. This suggests that I/O interconnects need to radically change every few years in order to maintain system performance. Presented by D. Sudhir, Roll CS 200118133

Conclusion The collective effort of industry leaders has successfully transitioned InfiniBand from technology demonstrations to the first real product deployments. The IBTA has a vision to improve and simplify the data center through InfiniBand technology and the fabric it by creating an interconnect for servers, communications and storage.
