IBTA
The InfiniBand Trade Association (IBTA). The IBTA is an industry consortium of more than
200 companies working together to develop a new common I/O specification designed to bring
greater scalability and performance to server I/O. InfiniBand defines a new channel based,
switched-fabric technology for server-to-server and server-to-I/O interconnection that is
expected to improve scalability and performance over existing PCI Bus technologies.
