Overlay
Networks
In order to better scale their networks, data center operators often create overlay networks that
carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as
NVGRE and VXLAN. While this solves network scalability issues, it hides the TCP packet from the
hardware offloading engines, placing higher loads on the host CPU. NVIDIA ConnectX-6 Lx
effectively addresses this by providing advanced NVGRE and VXLAN hardware offloading engines
that encapsulate and de-capsulate the overlay protocol.
RDMA
overConve
rged
Ethernet
(RoCE)
NVIDIA ConnectX-6 Lx, utilizing RoCE (RDMA over Converged Ethernet) technology, delivers low-
latency and high-performance over Band and Ethernet networks. Leveraging data center bridging
(DCB) capabilities, as well as NVIDIA ConnectX-6 Lx, advanced congestion control hardware
mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3
networks.
NVIDIA
PeerDirect
®
NVIDIA PeerDirect®communication provides high-efficiency RDMA access by eliminating
unnecessary internal data copies between components on the PCIe bus (for example, from GPU to
CPU), and therefore significantly reduces application run time. NVIDIA ConnectX-6 Lx advanced
acceleration technology enables higher cluster efficiency and scalability to tens of thousands of
nodes.

Uninstalling the Card
Safety Precautions
The adapter is installed in a system that operates with voltages that can be lethal. Before
uninstalling the adapter card, please observe the following precautions to avoid injury and prevent
damage to system components.
Remove any metallic objects from your hands and wrists.
It is strongly recommended to use an ESD strap or other antistatic devices.

Holding the adapter card from its center, gently pull the ConnectX-6 Lx out of the PCI Express
slot.
Cables and Modules
Cable Installation
All cables can be inserted or removed with the unit powered on.
To insert a cable, press the connector into the port receptacle until the connector is firmly
seated.
Support the weight of the cable before connecting the cable to the adapter card. Do
this by using a cable holder or tying the cable to the rack.
Determine the correct orientation of the connector to the card before inserting the
connector. Do not try and insert the connector upside down. This may damage the
adapter card.
Insert the connector into the adapter card. Be careful to insert the connector straight
into the cage. Do not apply any torque, up or down, to the connector cage in the
adapter card.
Make sure that the connector locks in place.
After inserting a cable into a port, the Green LED indicator will light when the physical
connection is established (that is, when the unit is powered on and a cable is plugged into
the port with the other end of the connector plugged into a functioning port).See LED
Interfaceunder the Interfaces section.
After plugging in a cable, lock the connector using the latching mechanism particular to the
cable vendor. When data is being transferred the Green LED will blink. See LED
Interfaceunder the Interfaces section.
Care should be taken as not to impede the air exhaust flow through the ventilation holes. Use
cable lengths which allow for routing horizontally around to the side of the chassis before
bending upward or downward in the rack.
To remove a cable, disengage the locks and slowly pull the connector away from the port
receptacle. LED indicator will turn off when the cable is unseated.

Get the device location on the PCI bus by running lspci and locating lines with the string “Mellanox
Technologies”:
lspci |grep -i Mellanox
Network controller: Mellanox Technologies MT2892 Family [ConnectX-6Lx]
On Windows
Open Device Manager on the server. ClickStart=>Run, and then enterdevmgmt.msc.
ExpandSystem Devicesand locate your NVIDIA ConnectX-6 Lx adapter card.

PCI Device (Example)
In theValuedisplay box, check the fields VEN and DEV (fields are separated by ‘&’). In the
display example above, notice the sub-string “PCI\VEN_15B3&DEV_1003”: VEN is equal to
0x15B3 – this is the Vendor ID of NVIDIA Technologies; and DEV is equal to 1018 (for
ConnectX-6 Lx) – this is a valid NVIDIA Technologies PCI Device ID.
If the PCI device does not have a NVIDIA adapter ID, return to Step 2 to check
another device.

The list of PCI Device IDs can be found in the PCI ID repository at http://pci-
ids.ucw.cz/read/PC/15b3.
