You could try temporarily to "down-grade" in this file: /etc/debian_version

I changed the debian_version to 7.5 and installation of driver seems to start, however it aborts with following error:
Error: One or more packages depends on MLNX_OFED.
Those packages should be removed before uninstalling MLNX_OFED:

glusterfs-common spiceterm pve-qmeu-kvm libpve-storage-perl qemu-server pve-manager

I am pretty sure it would be very bad thing for the proxmox node if i do remove them.
 
Is this what you see when installing a binary package or the source package?

You could try installing using: dpkg --force-depends -i package.deb

This should install the package disregarding the dependencies. As the error states the package will not remove the dependent packages itself.

The driver package came with its own installer script. I am only running the script. The driver folder have .deb packages in DEBS subfolder along documentation. The drive package was downloaded from here: http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers, for Debian 7.5 in .tgz. Should i try to run all the debs packages individually? But i am assuming if i do that it will asks for dependencies for every one of the debs in the sub folder.
 
You could also hope for a quick update to RHEL 6.6 kernel in proxmox.

  • All Mellanox mlx drivers have been updated to their latest upstream versions.
  • The ixbe driver has been updated to the latest upstream version.

And also:
[h=2]4.2. Networking[/h]


Mellanox SR-IOV SupportSingle Root I/O Virtualization (SR-IOV) is now supported as a Technology Preview in the Mellanox libmlx4 library and the following drivers:

  • mlx_core
  • mlx4_ib (InfiniBand protocol)
  • mlx_en (Ethernet protocol)

Package: kernel-2.6.32-335

I tried this command to install OFED drivers. Although the installation seem to go ok, after reboot none of the infiniband drivers were loaded. The installation appears to remove mlx4_ib drivers and other protocols. So based on the manual i used the uninstaller came with the package to uninstall OFED drivers only find out that it also removed packages such as pve, qemu and soem other. Unfortunately it did not ask me do i want to remove or cancel. It only showed what has been removed. So after a reboot i found out that services such as pveproxy, pvedaemon, pvestatd are missing and thus the node shows offline from GUI. This is a ceph node so i dont necessarily need qemu packages. The ceph OSDs are working just fine though.

Which packages do i need to install ir order get those services back. I am able to see content of /etc/pve/ so looks like cluster side is working.
 
I have just installed Mellanox ConnectX DDR and first test run with iperf:

Remember above is performance per connection and since this is running a dual test the numbers is showed per connection.

I am still waiting for my cables but I cannot wait until they arrive ;-)
 
Hi symmcom,

Did you remember this trick provided you have dual port HCA's?
cat /etc/sysctl.d/infiniband.conf
net.ipv4.conf.ib0.arp_ignore=1
net.ipv4.conf.ib1.arp_ignore=1
 
If your DDR IB card putting out that much bandwidth, my QDR cards must put out at least closer to yours. Below is a snippet of output after running your exact command. Not good.

Which driver did you use? Is it on Proxmox node?
 
It is installed in the Proxmox node.
