As the popularity of InfiniBand technology increases, the number of Linux distributions and open source organizations producing drivers and tools will increase. For up-to-date information, check with open source organizations and your current vendors.
The OpenFabrics organization is the Open Software solution in the InfiniBand software space and OpenFabrics Enterprise Distribution (OFED) is the InfiniBand suite of software produced by this organization. Various vendors contribute their drivers (and other software components) to OFED.
OFED contains the following components:

Warning: this is an old info extracted form Sun documentation. Despite discrepancies with version 2.1 it is still useful... See MLNX_OFED 2.1-X Release Notes
1. Verify what card you have:
lspci |grep -i Mellanox 03:00.0 Network controller [0207]: Mellanox Technologies MT27500 Family [ConnectX-3]
2. From root, extract the files by typing:
tar -zxvf MLNX_OFED_LINUX-2.1-1.0.0-rhel6.5-x86_64.tar3. From the create by tar directory initiate the installation process by typing ./mlnxofedinstall - This is the MLNX_OFED_LINUX installation script.

The Sun Blade Server Module is configured now to start up the InfiniBand software on reboot (ONBOOT=yes).
If this is not the desired behavior, you can edit the /etc/infiniband/openib.conf file, changing ONBOOT to equal no. You can also manually control basic InfiniBand behavior by entering the following command:
/etc/init.d/openibd option
where option can be start, stop, or status.
After the reboot, the Server Module should come up as a functional member of the InfiniBand fabric.
1. Verify that the Linux software driver is installed and attached to the IB EM by typing the openibd status command.
| Note - When using the openibd command, type the entire path as shown in the example. |
> /etc/init.d/openibd status
HCA driver loaded
Configured devices:
ib0
Currently active devices:
ib0
The following modules are also loaded:
ib_cm
ip_ipoib
.
.
.
2. To view details of operational status, type the ibstat command.
The following example shows one operational IB channel into the IB fabric (or network). The LinkUp state indicates active participation in an IB fabric. It is present as lid 69 and it is being managed by lid 2.
> ibstat CA 'mthca0' CA type: MT25204 Number of ports: 1 Firmware version: 1.1.0 Hardware version: a0 Node GUID: 0x001b00000ca72620 System image GUID: 0x001b00000ca72623 Port 1 State: Active Physical state: LinkUp Rate: 20 Base lid: 69 LMC: 0 SM lid: 2 Capability mask: 0x02510a68 Port GUID: 0x001b00000ca72621
You can also verify that the InfiniBand fabric is operational by entering the ibnetdiscover command. The output from this command will list all the nodes, as shown in the following sample output.

Our build out of the Open Compute Windmill V3 server utilizes the Mellanox MCX342A XCAN 10GbE, 2-p SFP+ mezzanine card. By default, the Mellanox card is not natively supported by CentOS 6.4.
[root@server /]# lspci | grep Mellanox 06:00.0 Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]That being said, I had to download the appropriate driver from Mellanox here.
That being said, I also needed quite a few RPM's to do the driver install, I did:
yum -y install kernel-source kernel headers gcc rpm-build gcc make patch redhat-rpm-configEven then, I was getting an error:
No kernel sources/headers found for 2.6.32-358.el6.x86_64 kernel.As it turns out, the symbolic link of /lib/modules/2.6.32-358.el6.x86_64/build to ../../../usr/src/kernels/xxxxxxx was incorrect. I had to do:
ln -s ../../../usr/src/kernels/2.6.32-358.23.2.el6.x86_64 buildwithin /lib/modules/2.6.32-358.el6.x86_64/
Only then was I able to correctly install the Mellanox driver.

I have the following ethernet card and after the upgrade to RHEL 6.,5 it stopped to work and I had to roll back to previous kernel.
Even downloading the latest driver it gets the following error.
MLNX_OFED_LINUX-2.0-3.0.0-rhel6.4-x86_64]# ./mlnxofedinstall
Error: The current MLNX_OFED_LINUX is intended for rhel6.4
# cat /etc/redhat-release

Where is the plan to release a driver for RHEL 6.5?
More information regarding the ethernet card.

Which kernel do you use? You can try to build an iso or tgz package using mlnx_add_kernel_support.sh script.
It has self-explanatory help. You'd run it for your running kernel (need to have installed all devel/source packages for current kernel), and it will create an iso or tgz image in /tmp. Then you will use that custom package to install ofed.

I was able to it to work with 6.5 by reverting grub back to kernel version 2.6.32-358, doing a yum downgrade for the kernel-{headers,devel,firmware} rpms, and then editing a couple of files in the iso and building a new one. The diffs for those are

If you have installed current releases of Red Hat Enterprise Linux Advanced Server (RHEL AS 4-U3 or later) or SUSE Linux Enterprise Server (SLES9 SP3 or later, SLES10) on a Sun Blade Server Module and you have installed the bundled drivers and OFED Release 1.2.5 or later, you do not need to install or configure additional drivers to support the IB ExpressModule (IB EM).
Specifically, RHEL AS 4-U4 contains support in the kernel for HCA hardware produced by Mellanox (mthca driver). The kernel also includes core InfiniBand modules, which provide the interface between the lower-level hardware driver and the upper-layer InfiniBand protocol drivers. The InfiniBand modules provide user space access to InfiniBand hardware.
The kernel also includes the Sockets Direct Protocol (SDP) driver, IP over Infiniband (IPoIB) and the SCSI RDMA Protocol (SRP) driver.
RHEL AS 4-U4 includes the following user space packages:
- kernel-ib. Base package that is required to support all other packages. Includes the files necessary to configure the kernel portion of the openib stack, create the proper udev rules, add the init script that allows the kernel modules to be selectively loaded at boot, and so on.
- dapl. RDMA API that supports the DAT 1.2 specification.
- ibibcm. InfiniBand Connection Management API.
- libibcommon. Common utility functions for the IB diagnostic and management tools.
- libibmad. Low-layer IB functions for use by the IB diagnostic and management programs, including MAD, SA, SMP, and other basic IB functions.
- libibumad. User MAD library functions that sit on top of the user MAD modules in the kernel. Used by the IB diagnostic and management tools, including OpenSM.
- libibverbs. Library that allows user space processes to use InfiniBand "verbs" as described in the InfiniBand Architecture Specification.
- libibverbs-utils. Useful subnet and device diagnostic utilities.
- libmthca. Device-specific user space driver for Mellanox HCAs (MT23108 InfiniHost and MT25208 InfiniHost III Ex) for use with the libibverbs library.
- libipathverbs. Device-specific driver for Pathscale HCAs for use with libibverbs (only available on x86_64 and ia64 systems).
- librdmacm. RDMA Connection Management (cm) library.
- libsdp. Driver that enables a sockets application to use InfiniBand Sockets Direct Protocol (SDP) instead of TCP transparently and without recompiling the application.
- openib-diags. Diagnostic programs and scripts that diagnose the IB subnet.
- opensm. Subnet manager software for InfiniBand networks.
- opensm-libs. Shared libraries for InfiniBand user space access.
- perftest. InfiniBand performance tests.
- srptools. In conjunction with the kernel ib_srp driver, allows discovery and and use of SCSI class devices via the SCSI RDMA Protocol over InfiniBand.
- mstflint. Tool to query and update firmware flash memory attached to Mellanox InfiniBand HCAs.
| Note - These package names can change, depending on the Linux OS. |
The packages selected to support any given configuration will vary. TABLE 3-1 lists the packages considered the absolute minimum needed to support the environment described in this guide.

If you elected not to install these packages when installing the Linux OS or if you want to upgrade your drivers, you can install these packages at any time from the OS distribution source or by downloading the required files from OpenFabrics.org. For information on both of these procedures, see Installing the InfiniBand Drivers on Linux.
As the popularity of InfiniBand technology increases, the number of Linux distributions and open source organizations producing drivers and tools will increase. For up-to-date information, check with open source organizations and your current vendors.
The OpenFabrics organization is the Open Software solution in the InfiniBand software space and OpenFabrics Enterprise Distribution (OFED) is the InfiniBand suite of software produced by this organization. Various vendors contribute their drivers (and other software components) to OFED.
TABLE 3-2 lists the tested Linux platforms and the corresponding OFED release.
|
Linux Platform |
OFED Release |
|---|---|
|
RHEL AS 4-U3 or later |
For RHEL AS 4-U3, Sun has tested OFED Release 1.2.5 of the OpenFabrics stack. Note: RHEL AS 4-U4 includes an older version of OFED, so you must install OFED Release 1.2.5 or a later version. |
|
SLES9 SP3 or later, SLES10 |
Sun has tested OFED Release 1.2.5 for the SLES10 platform. Note: You must have OFED Release 1.2.5 or a later version. |
OFED contains the following components:
If you did not install the InfiniBand drivers when installing the Linux OS, you can install them at any time from the OS distribution source or by downloading the necessary files from OpenFabrics.org.
To do so, choose one of the following procedures:
If you need to determine whether or not the drivers are already installed, see To Verify Driver Installation on Linux.
|
To install the InfiniBand drivers, you need access to the Red Hat Package Manager (RPM) files. Access to these files is dependent on your individual installation configuration (net boot, CD/DVD boot, .iso files, and so on). When you decide on the appropriate access method and package selection, you can add the packages to the KickStart configuration file (on RHEL) for automatic inclusion in future installations.
| Note - On a 32-bit RHEL4 system, all packages have a .i386.rpm extension (as shown in the following procedure). On a 64-bit RHEL4 system, all packages have a .x86_64.rpm extension instead. |
1. Enter the rpm -ivh command for each InfiniBand package that you need to install.
Packages must be installed in the following order:
The following example shows the installation of one package (libibcommon) and the resulting dialog on an RHEL AS 4-U4 32-bit system:
> rpm -ivh libibcommon-1.0-1.i386.rpm warning: libibcommon-1.0-1.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e Preparing... ##################################### [100%] 1:libibcommon ########################################### [100%] > rpm -ivh libibumad-1.0-1.i386.rpm . . . |
2. If you are running the CSH or TCSH shell, enter the rehash command to rebuild the shell's view of available executables.
3. Enter the ibstat command to verify that the OS sees the IB em.

4. (Optional) You can enter the ibnetdiscover command to verify the presence of an operational IB fabric.
For an example of the output of this command, see To Verify Driver Installation on Linux.
5. (Optional) You can check the status of the ib0 network interface to determine whether the ib_ipoib driver is installed.
For details on this step, see To Install IPoIB Driver.
|
| Note - The Sun Dual Port 4x DDR IB Host Channel Adapter PCIe ExpressModule requires OFED Release 1.2.5 or later. |
1. On the Sun Blade Server Module, log in as root and copy the required files from the following location:
http://www.openfabrics.org/downloads.htm
In the following example, OFED-1.2.5.tar is used only as an example.
| Note - You need Write access to the files to execute the install script. |
2. From root, extract the files by typing:
> tar -zxvf OFED-1.2.5.tar |
3. From the OFED-1.2.5 directory, initiate the installation process by typing:
> ./install.sh |
4. When the InfiniBand OFED Distribution Software Installation Menu appears, select option 2 (Install OFED Software).
5. When the Select OFED Software menu appears, select option 3 (All packages).
6. When you are asked if you wish to create/install an MPI RPM with gcc,
enter n.
The following compiler(s) on your system can be used to build/install MPI: gcc Do you wish to create/install an MPI RPM with gcc? [Y/n]: n |
7. Next, you are asked if you wish to create/install an openmpi RPM with gcc. Again, type n.
The following compiler(s) on your system can be used to build/install openmpi: gcc Do you wish to create/install an openmpi RPM with gcc? [Y/n]: n |
The installation script lists the OFED packages that it will build. See the following sample output.
Following is the list of OFED packages that you have chosen (somemay have been added by the installation program due to package dependencies): ib_ipath ib_ipoib ... mpitests ibutils WARNING: This installation program will remove any previouslyinstalled IB packages on your machine. Do you want to continue? [Y/n]: Y |
8. Type Y to continue, as shown above.
Next, you are prompted to configure InfiniBand IP support.
9. Type Y when asked if you want to include IPoIB configuration files.
Do you want to include IPoIB configuration files (ifcfg-ib*)? [Y/n]: Y |
10. Press Enter to accept the default when prompted to enter a temporary directory for OFED.
RPM build process requires a temporary directory. Please enter the temporary directory [/var/tmp/OFED]: |
11. Press Enter to accept the default when prompted for the OFED installation directory.
Please enter the OFED installation directory [/usr/local/ofed]: |
At this point, the installer begins compiling InfiniBand packages. The process of building packages takes approximately 15-20 minutes.
The system displays output like the following:
The MPI_COMPILER_openmpi variable is not defined. Trying the default compiler: gcc The following compiler(s) will be used to build the openmpi RPM(s): gcc Checking dependencies. Please wait ... Building InfiniBand Software RPMs. Please wait... Building openib RPMs. Please wait... . . . 33 packages were built Build process finished ... |
Installation begins. See the following message.
Removing previous InfiniBand Software installation Running /bin/rpm -e libibverbs libibverbs-devel libibverbs-utils... |
The actual installation takes about one minute.
Assuming the IB EM hardware is installed (and, therefore, an InfiniBand HCA is present), you are prompted to configure InfiniBand IP support.
12. Enter Y in response to the following prompt:
Do you want to configure IPoIB interfaces [Y/n]? Y |
The default IPoIB interface configuration is based on DHCP. A special patch for DHCP is required for supporting IPoIB. The patch is available under:
OFED-1.2.5/docs/dhcp
If you do not have DHCP, you must change this configuration in the following steps.
The system next displays the current configuration.
13. When asked if you want to change the configuration as displayed, type y.
The current IPOIB configuration for ib0 is: DEVICE=ib0 BOOTPROTO=dhcp ONBOOT=yes Do you want to change this configuration? [y/N]: Y |
The configuration script guides you through the changes one at a time. See the following as an example.
Enter an IP Address:10.0.0.52 Enter the Netmask: 255.255.255.0 Enter the Network:10.0.0.0 Enter the Broadcast Address:10.0.0.255 Start Device On Boot? [Y/n]:Y Selected configuration: IPADDR=10.0.0.52 NETMASK=255.255.255.0 NETWORK=10.0.0.0 BROADCAST=10.0.0.255 ONBOOT=yes Do you want to save the selected configuration? [Y/n]: Y |
14. Type Y to save the configuration.
If you have entered a valid IP configuration for ib0, you are now properly configured for IPoIB operations.
15. Iterate the InfiniBand configuration over all InfiniBand interfaces.
Enter a valid IP configuration for each network interface.
Once all IPoIB interfaces have been configured, you are prompted as follows to configure OpenSM for the blade.
Do you want to configure OpenSM [Y/n]? n |
16. Enter n to complete this part of the installation.
You should see a message like the following.
Installation finished successfully... Press Enter to continue... |
17. Press Enter.
The InfiniBand OFED Distribution Software Installation Menu is displayed.
18. Type Q to exit.
The Sun Blade Server Module is configured now to start up the InfiniBand software on reboot (ONBOOT=yes).
If this is not the desired behavior, you can edit the /etc/infiniband/openib.conf file, changing ONBOOT to equal no. You can also manually control basic InfiniBand behavior by entering the following command:
/etc/init.d/openibd option |
where option can be start, stop, or status.
19. After a successful installation, reboot the Server Module.
After the reboot, the Server Module should come up as a functional member of the InfiniBand fabric.
|
1. Verify that the Linux software driver is installed and attached to the IB EM by typing the openibd status command.
| Note - When using the openibd command, type the entire path as shown in the example. |
The following example shows the IB driver installed, running and presenting one IB HCA channel or network device (ibn) to the OS. In the example, the Linux network device appears as ib0.
> /etc/init.d/openibd status
HCA driver loaded
Configured devices:
ib0
Currently active devices:
ib0
The following modules are also loaded:
ib_cm
ip_ipoib
.
.
.
