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.
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.

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
- 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.
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.
-
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.

Installing Mellanox OFED
Installation Script
The installation script, mlnxofedinstall, performs the following:
• Discovers the currently installed kernel
- Uninstalls any software stacks that are part of the standard operating system distribution or another vendor's commercial stack
- Installs the MLNX_OFED_LINUX binary RPMs (If they are available for the current kernel)
- Identifies the currently installed InfiniBand and Ethernet network adapters and automatically upgrades the firmware.
Note: The firmware will not be updated if you run the install script with the --without-fw-update' option.
Note: If you wish to perform a firmware upgrade using customized FW binaries, you can provide a path to the folder that contains the FW binary files, by running --fw-image-dir. Using this option, the FW version embedded in the MLNX_OFED package will be ignored. Example:
./mlnxofedinstall --fw-image-dir /tmp/my_fw_bin_files
Usage
./mnt/minxofedinstall [OPTIONS]
Pre-existing configuration files will be saved with the extension ".conf.rpmsave".
The installation script removes all previously installed Mellanox OFED packages and re-installs from scratch. You will be prompted to acknowledge the deletion of the old packages.
- If you need to install Mellanox OFED on an entire (homogeneous) cluster, a common strategy is to mount the ISO image on one of the cluster nodes and then copy it to a shared file system such as NFS. To install on all the cluster nodes, use cluster-aware tools (such as pdsh).
- If your kernel version does not match with any of the offered pre-built RPMs, you can add your kernel version by using the "mlnx_add_kernel_support.sh" script located inside the MLNX_OFED package.
On Redhat and SLES distributions with errata kernel installed there is no need to use the mlnx_add_kernel_support.sh script. The regular installation can be performed and weak updates mechanism will create symbolic links to the MLNX_OFED kernel modules.
The "mlnx_add_kernel_support.sh" script can be executed directly from the mlnxofedinstall script. For further information, please see '--add-kernel-support' option below.
On Ubuntu and Debian distributions drivers installation use Dynamic Kernel Module Support (DKMS) framework. Thus, the drivers' compilation will take place on the host during MLNX_OFED installation. Therefore, using "mlnx_add_kernel_support.sh" is irrelevant on Ubuntu and Debian distributions.
Example
The following command will create a MLNX_OFED_LINUX ISO image for RedHat 6.3 under the /tmp directory.
<h1 id="mlnx_ofed_linux-xx-x-rhe163-x86_64mlnx_add_kernel_supportsh-m-tmpmlnx_ofed_linux-xx-x-rhe163-x86_64-make-tgz">./MLNX_OFED_LINUX x.x x-rhe16.3 x86_64/mlnx_add_kernel_support.sh -m /tmp/MLNX_OFED_LINUX x.x x-rhe16.3 x86_64/ --make-tgz</h1>
Note: This program will create MLNX_OFED_LINUX TGZ for rhel6.3 order /tmp directory.
All Mellarox, ORM, OPED, or Distribution TR packages will be removed.

- The script adds the following lines to /etc/security/limits.conf for the userspace components such as MPI:
• * soft memlock unlimited
• * hard memlock unlimited
- These settings set the amount of memory that can be pinned by a user space application to unlimited. If desired, tune the value unlimited to a specific amount of RAM.
For your machine to be part of the InfiniBand/VPI fabric, a Subnet Manager must be running on one of the fabric nodes. At this point, Mellanox OFED for Linux has already installed the OpenSM Subnet Manager on your machine.
For the list of installation options, run:
./mInxofedinstali --h
The DKMS (on Debian based OS) and the weak-modules (RedHat OS) mechanisms rebuild the initrd/initramfs for the respective kernel in order to add the MLNX_OFED drivers. When installing MLNX_OFED without DKMS support on Debian based OS, or without KMP support on RedHat or any other distribution, the initramfs will not be changed. Therefore, the Inbox drivers may be loaded on boot. In this case, openbd service script will automatically unload them and load the new drivers that come with MLNX_OFED.
Installation Procedure
- Login to the installation machine as root.
- Mount the ISO image on your machine.

| Firmware The firmware of existing network adapter devices will be updated if the following two conditions are fulfilled:The installation script is run in default mode; that is, without the option --without-fw-update'The firmware version of the adapter device is older than the firmware version included with the Mellanox OFED ISO image Note: If an adapter's flash was originally programmed with an Expansion ROM image, the automatic firmware update will also burn an Expansion ROM image.In case that your machine has an unsupported network adapter device, no firmware update will occur and the error message below will be printed.The firmware for this device is not distributed inside Mellanox driver:0000:01:00.0 (PSID: IBM2150110033)To obtain firmware for this device, please contact your HW vendor. |
Installation Logs
While installing MLNX_OFED, the install log for each selected package will be saved in a separate log file. The path to the directory containing the log files will be displayed after running the installation script in the following format: "Logs dir: /tmp/MLNX_OFED_LINUX-
Example:
Logs dir: /tmp/ELNX_OFED_LINUX-4.4-1.0.0.0.63414.logs
openibd Script
As of MLNX_OFED v2.2-1.0.0 the openibd script supports pre/post start/stop scripts: This can be controlled by setting the variables below in the /etc/infiniband/openibd.conf file.
OPEN1BD_PRE_START
OPEN1BD_POST_START
OPENTBD_PRE_STOP
OPENTBD_POST_STOP
Example:
OPENTBD_POST_START=/sbin/openibd_post.start.sh
An example of OPENIBD_POST_START script for activating all interfaces is provided in the MLNX_OFED package under the docs/scripts/openibd-post-start-configure-interfaces/folder.
Driver Load Upon System Boot
Upon system boot, the Mellanox drivers will be loaded automatically.
To prevent automatic load of the Mellanox drivers upon system boot:
- Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
blacklist mlx4_core
blacklist mlx4_en
blacklist mlx5_core
blacklist mlx5_ib
- Set "ONBOOT=no" in the "/etc/infiniband/openib.conf" file.
- If the modules exist in the initramfs file, they can automatically be loaded by the kernel. To prevent this behavior, update the initramfs using the operating systems' standard tools. Note: The process of updating the initramfs will add the blacklists from step 1, and will prevent the kernel from loading the modules automatically.

Updating the Device Manually
To update the device manually, please refer to the OEM Firmware Download page at http://www.mellanox.com/page/firmware_table_dell?mtag=oem_firmware_download.
In case that you ran the mlnxofedinstall script with the --without-fw-update' option or you are using an OEM card and now you wish to (manually) update firmware on your adapter card(s), you need to perform the steps below. The following steps are also appropriate in case that you wish to burn newer firmware that you have downloaded from Mellanox Technologies' Web site (http://www.mellanox.com > Support > Firmware Download).
- Get the device's PSID.
mlxfmanager_pci | grep PSID
PSID: MT_1210110019
-
Download the firmware BIN file from the Mellanox website or the OEM website.
-
Burn the firmware.
mixfmanager_pci -i <fw_file.bin>
- Reboot your machine after the firmware burning is completed.
Updating the Device Firmware Automatically upon System Boot
As of MLNX_OFED v3.1-x.x.x, firmware can be automatically updated upon system boot. The firmware update package (mlnx-fw-updater) is installed in the "/opt/mellanox/mlnx-fw-updater" folder, and openibd service script can invoke the firmware update process if requested on boot.
If the firmware is updated, the following message is printed to the system's standard logging file:
fw_updater: Firmware was updated. Please reboot your system for the changes to take effect.
Otherwise, the following message is printed:
fw_updater: Didn't detect new devices with old firmware.
Please note, this feature is disabled by default. To enable the automatic firmware update upon system boot, set the following parameter to "yes" "RUN_FW_UPDATER_ONBOOT=yes" in the openlbd service configuration file "/etc/infiniband/openib.conf".
You can opt to exclude a list of devices from the automatic firmware update procedure. To do so, edit the configurations file "/opt/mellanox/mlnx-fw-updater/mlnx-fw-updater.conf" and provide a comma
separated list of PCI devices to exclude from the firmware update. Example:
MLNX_EXCLUDE_DEVICES="00:05.0,00:07.0"
UEFI Secure Boot
All kernel modules included in MLNX_OFED for RHEL7 and SLES12 are signed with x.509 key to support loading the modules when Secure Boot is enabled.
Enrolling Mellanox's x.509 Public Key on Your Systems
In order to support loading MLNX_OFED drivers when an OS supporting Secure Boot boots on a UEFI-based system with Secure Boot enabled, the Mellanox x.509 public key should be added to the UEFI Secure Boot key database and loaded onto the system key ring by the kernel. Follow these steps below to add the Mellanox's x.509 public key to your system:
Prior to adding the Mellanox's x.509 public key to your system, please make sure that (1) The 'mokutil' package is installed on your system, and (2) The system is booted in UEFI mode.
- Download the x.509 public key.
<h1 id="wget-httpwwwmellanoxcomdownloadsofedmlnx_signing_key_pubder">wget http://www.mellanox.com/downloads/ofed/mlnx_signing_key_pub.der</h1>
- Add the public key to the MOK list using the mokutil utility.
<h1 id="mokutil-import-mlnx_signing_key_pubder">mokutil --import mlnx_signing_key_pub.der</h1>
- Reboot the system.
The pending MOK key enrollment request will be noticed by shim.efi and it will launch MokManager.efi to allow you to complete the enrollment from the UEFI console. You will need to enter the password you previously associated with this request and confirm the enrollment. Once done, the public key is added to the MOK list, which is persistent. Once a key is in the MOK list, it will be automatically propagated to the system key ring and subsequent will be booted when the UEFI Secure Boot is enabled.
To see what keys have been added to the system key ring on the current boot, install the 'keyutils' package and run: #keyctl list %:.system_keyring#
Removing Signature from kernel Modules
The signature can be removed from a signed kernel module using the 'strip' utility which is provided by the 'binutils' package. The strip utility will change the given file without saving a backup. The operation can be undo only by resigning the kernel module. Hence, we recommend backing up a copy prior to removing the signature.
To remove the signature from the MLNX\_OFED kernel modules:
- Remove the signature.
<h1 id="rpm-qa-grep-e-kernel-ibmlnx-ofa_kernelisersrpknemmlnx-rdsmlnx-nfsrdmamlnx-nvmemlnx-rdma-rxe-xargo-rpm-ql-grep-kcs-xargo-strip-g">rpm -qa | grep -E "kernel-ib|mlnx-ofa_kernel|iser|srp|knem|mlnx-rds|mlnx-nfsrdma|mlnx-nvme|mlnx-rdma-rxe" | xargo rpm -ql | grep ".kcs" | xargo strip -g</h1>
After the signature has been removed, a massage as the below will no longer be presented upon module loading:
"Request for u-known module key 'Mellanox Technologies signing keys: 61feb0747c/292f958419386ffdd9d5ca999e403' err -11"
However, please note that a similar message as the following will still be presented:
"my_module: module verification failed: signature and/or required key missing - tailing kernel"
This message is only presented once, upon first module boot that either has no signature or whose key is not in the kernel key ring. Therefore, this message may go unnoticed. Once the system is rebooted after unloading and reloading a kernel module, the message will appear. (Note that this message cannot be eliminated.)
- Update the initramfs on RHEL systems with the stripped modules.
rkinitrd /bool./initramfs-(uname -r).ing(uname -r) --force

Updating Adapter Firmware
Each adapter card is shipped with the latest version of qualified firmware at the time of manufacturing. However, Mellanox issues firmware updates occasionally that provide new features and bug fixes. To check that your card is programmed with the latest available firmware version, download the mlxup firmware update and query utility. The utility can query for available Mellanox adapters and indicate which adapters require a firmware update. If the user confirms, mlxup upgrades the firmware using embedded images. The latest mlxup executable and documentation are available from http://www.mellanox.com > Products > Software > Firmware Tools.

PCIe Express Pinouts Description for Single-Slot Socket Direct Card
This section applies to ConnectX-6 single-slot cards (MCX653105A-EFAT and MCX653106A-EFAT).
ConnectX-6 single-slot Socket Direct cards offer 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. The PCIe x16 interface is split into 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.
In order to allow this capability, a system with a special PCI Express x16 slot is required. Table 31 provides the pin definitions of the required four special PCIe pins.
| PCIe pin # | Server Connection for 2x PCIe x8 mode Server | Connection for 1x PCIe x16 mode | Comments |
| B82 | 1Kohm pull up to 3.3VAUX Either leave | unconnected or pulled to GND | Configure the card to work at 2x PCIe x8 or 1x PCIe x16 modes |
| A32 | P signal of differential PCIe clock (100MHz nominally) of the CPU which connects to PCIe lanes 15-8 of the PCIe connector | Not Connected | PCIe clock for ConnectX-6 PCIe bus lanes [15:8] |
| A33 | N signal of differential PCIe clock (100MHz nominally) of the CPU which connects to PCIe lanes 15-8 of the PCIe connector | Not Connected | |
| A50 | PERST signal from the CPU which connects to PCIe lanes 15-8 of the PCIe connector | Not Connected PERST (PCIe Reset) for ConnectX-6 PCIe bus lanes [15:8] | |
Finding the GUID/MAC on the Adapter Card
Each Mellanox adapter card has a different identifier printed on the label: serial number and the card MAC for the Ethernet protocol and the card GUID for the InfiniBand protocol. VPI cards have both a GUID and a MAC (derived from the GUID).
The product revisions indicated on the labels in the following figures do not necessarily represent the latest revisions of the cards.
