== Overview ==
 
−
The NVSwitch was introduced with the launch of Nvidia's {{nvidia|DGX-2}} computer. The NVSwitch is a 2 billion transistor, 18-port, {{nvidia|NVLink}} switch. With each port operating at 50 GB/s, the switch has a total bandwidth of 900 GB/s. The switch allows up to any nine devices to be routed to any of the other nine devices. In addition to the NVLink ports, the switch has addition I/O for control and management including x4 [[PCIe]] Gen 2 management port, [[I²C]], and [[GPIO]].

The DGX-2 uses 6 NVLinks per baseboard to create a fully-connected network of GPUs.

The DGX-2 has two baseboards to fully connect all 16 {{nvidia|V100}} GPUs to each other. Each switch does have 2 ports unused. It's possible those ports will be used in configurations involving the {{ibm|POWER9}} microprocessors which have native support for NVLink 2.0.
