Re: mellanox mhqh29b-xtr dual ethernet adapter install
grep -i 15b3 /lib/modules/3.10.0-693.2.2.el7.x86_64/modules.* | grep -i 673c says that's supported by the mlx4_core module in the current CentOS 7 kernel.
The future appears to be RHEL or Debian. I think I'm going Debian.

but how to install drivers and how to inter-server communication ?

Re: mellanox mhqh29b-xtr dual ethernet adapter install
Try running modprobe mlx4_core and then look in /var/log/messages and/or dmesg to see what that says. If lsmod reports it already loaded then modprobe -r it and then modprobe it so you see the current set of messages in the logs.

If you install infiniband-diags you can check the output of "ibstat". Depending on what you want, you can set the "link_layer" to either Ethernet or Infiniband via the mlx4_core module option "port_type_array", like if you have a dual-port adapter:
options mlx4_core port_type_array=1,2
in /etc/modprobe.d/mlx4.conf to set the first port to link layer Infiniband and the second port to Ethernet.
