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 Networks

In order to better scale their networks, datacenter 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. ConnectX-6 effectively addresses this by providing advanced NVGRE and VXLAN hardware offloading engines that encapsulate and de-capsulate the overlay protocol.

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.

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

Installing Mellanox OFED

./mlnxofedinstall --fw-image-dir /tmp/my_fw_bin_files

./mnt/mlnxofedinstall [OPTIONS]

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-fwupdate’ 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:

Usage

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

# ./MLNX_OFED_LINUX-x.x-x-rhel6.3-x86_64/mlnx_add_kernel_support.sh -m /tmp/MLNX_OFED_LINUX-x.x-x-rhel6.3x86_64/ --make-tgz Note: This program will create MLNX_OFED_LINUX TGZ for rhel6.3 under /tmp directory.

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:

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, openibd service script will automatically unload them and load the new drivers that come with MLNX_OFED.

Installation Procedure

Mount the ISO image on your machine.

Run the installation script.

For unattended installation, use the --force installation option while running the



Installation Results

Software Most of MLNX_OFED packages are installed under the “/usr” directory

Firmware The firmware of existing network adapter devices will be updated if the

• except for the following packages which are installed under the “/opt” directory:

•

fca and ibutils

•

The kernel modules are installed under

•

/lib/modules/`uname -r`/updates on SLES and Fedora Distributions

•

/lib/modules/`uname -r`/extra/mlnx-ofa_kernel on RHEL and other Red Hat like Distributions

• 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-<version>.<PD>.logs".

Example:

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.

OPENIBD_PRE_START OPENIBD_POST_START OPENIBD_PRE_STOP OPENIBD_POST_STOP

Example:

OPENIBD_POST_START=/sbin/openibd_post_start.sh

blacklist mlx4_core blacklist mlx4_en blacklist mlx5_core blacklist mlx5_ib

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.

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.

Where:

Note: MLNX_OFED provides kernel module RPM packages with KMP support for RHEL and SLES. For other operating systems, kernel module RPM packages are provided only for the operating systems' default kernel. In this case, the group RPM packages have the supported kernel version in their package's name.

Example:

If you have an operating system different than RHEL or SLES, or you have installed a kernel that is not supported by default in MLNX_OFED, you can use the mlnx_add_kernel_support.sh script to build MLNX_OFED for your kernel. The script will automatically build the matching group RPM packages for your kernel so that you can still install MLNX_OFED via yum. Please note that the resulting MLNX_OFED repository will contain unsigned RPMs, therefore, you should set 'gpgcheck=0' in the repository configuration file.

To update the device online on the machine from the Mellanox site, use the following command line:

Example:

mlxfwmanager --online -u -d 0000:09:00.0 Querying Mellanox devices firmware ... Device #1:

---------Device Type: ConnectX-5 Part Number: Description: PSID: MT_1020120019 PCI Device Name: 0000:09:00.0 Port1 GUID: 0002c9000100d051 Port2 MAC: 0002c9000002 Versions: Current Available FW 2.32.5000 2.33.5000 Status: Update required

--------Found 1 device(s) requiring firmware update. Please use -u flag to perform the update.

Updating the Device Manually

mlxfwmanager_pci | grep PSID PSID: MT_1210110019

mlxfwmanager_pci -i <fw_file.bin>

fw_updater: Firmware was updated. Please reboot your system for the changes to take effect.

fw_updater: Didn't detect new devices with old firmware.

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.

Download the firmware BIN file from the Mellanox website or the OEM website.

Burn the firmware.

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:

Otherwise, the following message is printed:

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 openibd 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.

MLNX_EXCLUDE_DEVICES="00:05.0,00:07.0"

# wget http://www.mellanox.com/downloads/ofed/mlnx_signing_key_pub.der

# mokutil --import mlnx_signing_key_pub.der

Example:

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 UEFIbased 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.

Add the public key to the MOK list using the mokutil utility.

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.

After the signature has been removed, a massage as the below will no longer be presented upon

"Request for unknown module key 'Mellanox Technologies signing key: 61feb074fc7292f958419386ffdd9d5ca999e403' err -11"

"my_module: module verification failed: signature and/or required key missing - tainting kernel"

mkinitrd /boot/initramfs-$(uname -r).img $(uname -r) --force

module loading:

However, please note that a similar message as the following will still be presented:

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.

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 SingleSlot 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.
