InfiniBand is a bus of high speed serial communications, designed for both internal and external connections. Infiniband uses a bidirectional serial bus so that avoids the typical problems associated with parallel buses over long distances (in this context, a room or building). Despite being a serial connection, it is very fast, giving a gross rate of 2.5 Gigabits per second (Gbps) in each directionper link.

The SFF connectors are distinguished by their smaller size, they are ideal for saving space. The SFF connectors also increase port density cards, switches etc ..

Gbps (Gb/s, Gbit/s) is the speed with which information is transmitted. It is normally used to measure the speed information in the ADSL/fiber addresses transmitted.

• 1 Gb/s is equivalent to 1,000,000,000 b/s.
• 1 Gb/s is equivalent to 1000000 kb/s.
• 1Gb/s equals 1000 Mb/s.
