Physical interconnectionEdit

InfiniBand switch with CX4/SFF-8470 connectors

In addition to a board form factor connection, it supports both active and passive copper (up to 30 meters) and optical fiber cable (up to 10 km).[9] QSFP connectors are used.

The Inifiniband Association also specified theCXP copper connector system for speeds up to 120 Gbit/s over copper and active optical cables.

APIEdit

InfiniBand has no standard API. The standard only lists a set of verbs like ibv_open_deviceor ibv_post_send, which are abstract representations of functions or methods that must exist. The syntax of these functions is left to the vendors. The de facto standard software stack is that developed byOpenFabrics Alliance. It is released under two licenses GPL2 or BSD license for GNU/Linux and FreeBSD, and as WinOF under a choice of BSD license for Windows. It has been adopted by most of the InfiniBand vendors, for GNU/Linux, FreeBSD, and Windows.
