Overview[edit]
The NVSwitch was introduced with the launch of Nvidia's DGX-2 computer. The NVSwitch is a 2 billion transistor, 18-port, 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 V100 GPUs to each other. Each switch does have 2 ports unused. It's possible those ports will be used in configurations involving the POWER9 microprocessors which have native support for NVLink 2.0.
