ConnectX-6 Socket Direct™ Cards
The Socket Direct technology offers improved performance to dual-socket servers by enabling direct access from each CPU in a dual-socket server to the network through its dedicated PCIe interface.
Please note that ConnectX-6 Socket Direct cards do not support Multi-Host functionality (i.e. connectivity to two independent CPUs). For ConnectX-6 Socket Direct card with Multi-Host functionality, please contact Mellanox.
11
ConnectX-6 Socket Direct cards are available in two configurations: Dual-slot Configuration (2x PCIe x16) and Single-slot Configuration (2x PCIe x8).
ConnectX-6 Dual-slot Socket Direct Cards (2x PCIe x16)
In order to obtain 200Gb/s speed, Mellanox offers ConnectX-6 Socket Direct that enable 200Gb/s connectivity also for servers with PCIe Gen 3.0 capability. The adapter’s 32-lane PCIe bus is split into two 16-lane buses, with one bus accessible through a PCIe x16 edge connector and the other bus through an x16 Auxiliary PCIe Connection card. The two cards should be installed into two PCIe x16 slots and connected using two Cabline SA-II Plus harnesses, as shown in the below figure.

ConnectX-6 Single-slot Socket Direct Cards (2x PCIe x8 in a row)
The PCIe x16 interface comprises two PCIe x8 in a row, such that each of the PCIe x8 lanes can be connected to a dedicated CPU in a dual-socket server. In such a configuration, Socket Direct brings lower latency and lower CPU utilization as the direct connection from each CPU to the network means the interconnect can bypass a QPI (UPI) and the other CPU, optimizing performance and improving latency. CPU utilization is improved as each CPU handles only its own traffic and not traffic from the other CPU.
A system with a custom PCI Express x16 slot that includes special signals is required for installing the card. Please refer to PCIe Express Pinouts Description for Single-Slot Socket Direct Card for pinout definitions.

Overlay In order to better scale their networks, datacenter operators often create overlay networks that Networks 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. ConnectX-6 effectively addresses this by providing advanced NVGRE and VXLAN hardware offloading engines that encapsulate and de-capsulate the overlay protocol.
RDMA and ConnectX-6, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged RDMA over Ethernet) technology, delivers low-latency and high-performance over InfiniBand and Ethernet Converged networks. Leveraging datacenter bridging (DCB) capabilities as well as ConnectX-6 advanced Ethernet congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services (RoCE) over Layer 2 and Layer 3 networks.
Mellanox PeerDirect™ communication provides high efficiency RDMA access by eliminating unnecessary PeerDirect internal data copies between components on the PCIe bus (for example, from GPU to CPU), and
™therefore significantly reduces application run time. ConnectX-6 advanced acceleration technology enables higher cluster efficiency and scalability to tens of thousands of nodes.

Please refer to the Specifications section for airflow numbers for each specific card model.
Airflow from the heatsink to the network ports:
22
Airflow from the network ports to the heatsink:
All cards in the system should be planned with the same airflow direction.
Software Requirements
•See Operating Systems/Distributions section under the Introduction section.
•Software Stacks - Mellanox OpenFabric software package MLNX_OFED for Linux, WinOF-2 for Windows, and VMware. See the Driver Installation section.
Safety Precautions
The adapter is being installed in a system that operates with voltages that can be lethal. Before opening the case of the system, observe the following precautions to avoid injury and prevent damage to system components.
•Remove any metallic objects from your hands and wrists.
•Make sure to use only insulated tools.
•Verify that the system is powered off and is unplugged.
•It is strongly recommended to use an ESD strap or other antistatic devices.
23
Pre-Installation Checklist
•Unpack the ConnectX-6 Card; Unpack and remove the ConnectX-6 card. Check against the package contents list that all the parts have been sent. Check the parts for visible damage that may have occurred during shipping. Please note that the cards must be placed on an antistatic surface. For package contents please refer to Package Contents.
Please note that if the card is removed hastily from the antistatic bag, the plastic ziplock may harm the EMI fingers on the networking connector. Carefully remove the card from the antistatic bag to avoid damaging the EMI fingers.
•Shut down your system if active; Turn off the power to the system, and disconnect the power cord. Refer to the system documentation for instructions. Before you install the ConnectX-6 card, make sure that the system is disconnected from power.
•(Optional) Check the mounting bracket on the ConnectX-6 or PCIe Auxiliary Connection Card; If required for your system, replace the full-height mounting bracket that is shipped mounted on the card with the supplied low-profile bracket. Refer to Bracket Replacement Instructions.
Bracket Replacement Instructions
The ConnectX-6 card and PCIe Auxiliary Connection card are usually shipped with an assembled highprofile bracket. If this form factor is suitable for your requirements, you can skip the remainder of this section and move to Installation Instructions. If you need to replace the high-profile bracket with the short bracket that is included in the shipping box, please follow the instructions in this section.
Due to risk of damaging the EMI gasket, it is not recommended to replace the bracket more than three times.
To replace the bracket you will need the following parts:
•The new brackets of the proper height
•The 2 screws saved from the removal of the bracket
Removing the Existing Bracket
1.Using a torque driver, remove the two screws holding the bracket in place.
2.Separate the bracket from the ConnectX-6 card.
Be careful not to put stress on the LEDs on the adapter card.
3.Save the two screws.
Installing the New Bracket
1.Place the bracket onto the card until the screw holes line up.
Do not force the bracket onto the adapter card.
2.Screw on the bracket using the screws saved from the bracket removal procedure above.
24
Use a torque driver to apply up to 2 lbs-in torque on the screws.

Cables and Modules
To obtain the list of supported Mellanox cables for your adapter, please refer to the Cables Reference Table at http://www.mellanox.com/products/interconnect/cables-configurator.php.
Cable Installation
1.All cables can be inserted or removed with the unit powered on.
2.To insert a cable, press the connector into the port receptacle until the connector is firmly seated.
a.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.
b.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.
c.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.
d.Make sure that the connector locks in place.
When installing cables make sure that the latches engage.
Always install and remove cables by pushing or pulling the cable and connector in a straight line with the card.
3.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.
25
4.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.
5.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.
6.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.
