InfiniBand is a switched fabric communications link used in high-performance computing and enterprise data centers.
Its features include high throughput, low latency, quality of service and failover, and it is designed to be scalable. The InfiniBand architecture specification defines a connection between processor nodes and high performance I/O nodes such as storage devices. Infiniband host bus adapters and network switches are manufactured by Mellanox and Intel (which acquired Qlogic's infiniband business in January 2012).
InfiniBand forms a superset of the Virtual Interface Architecture (VIA).
