[Starlingx-discuss] stx 6.0 aio mellenox connectX 40GB dual card

[M. Vefa Bicakci]

Hi,

StarlingX 5.0.1 release has Mellanox OFED v5.1, and I just checked that the RPM file linked below indeed has the mlx4* kernel modules, so I believe that StarlingX 5.0.1 ought to work with Mellanox ConnectX-3 cards:

  http://mirror.starlingx.cengn.ca/mirror/starlingx/release/5.0.1/centos/distro/outputs/RPMS/std/mlnx-ofa_kernel-modules-5.0-OFED.5.0.2.1.8.1.g5f67178.tis.2.x86_64.rpm

It could be possible to adapt Mellanox OFED v4.9 to StarlingX 6.0, but I am not aware of anyone who has tried this, so it is difficult for me comment with certainty.

Thank you,

Vefa
