On Windows
1. Open Device Manager on the server. Click Start => Run, and then enter devmgmt.msc.
2. Expand System Devices and locate your NVIDIA ConnectX-6 adapter card.
3. Right click the mouse on your adapter's row and select Properties to display the adapter card
properties window.
4. Click the Details tab and select Hardware Ids (Windows 2012/R2/2016) from
the Property pull-down menu.

In the output example above, the first
two rows indicate that one card is installed in a PCI slot with PCI Bus address 05
(hexadecimal), PCI Device number 00 and PCI Function number 0 and 1. The other
card is installed in a PCI slot with PCI Bus address 82 (hexa-decimal), PCI Device numb
er 00 and PCI Function number 0 and 1.
Since the two PCIe cards are installed in two PCIe slots, each card
gets a unique PCI Bus and Device number. Each of the PCIe x16 busses sees two network
ports; in effect, the two
physical ports of the ConnectX-6 Socket Direct adapter are viewed as four net
devices by the system.
