Thanks for the tips. We make heavy use of SR-IOV, which seems to work better when using current OFED drivers. With regards to performance, pause-frame based flow control and PFC is disabled across our network, so we are keen to experiment with drivers.

I'll run this test when next possible. For this machine, sequential R/W is paramount as it's serving large assets to video editor clients.

As a comparison, I'm running a 15TB mdadm ext4 array on the following hardware: EPYC 7443P 24-core CPU 256GB 8-channel RAM 8x Samsung PM9A3 Gen4 NVME U.2 1.92TB drives, connected via 2x AOC-SLG4-4E4T-O bifurcation re-timer cards Seeing ~40GB/s read and ~20GB/s write via a sequential FIO test.

Thank you for the quick reply! I'll check the firmware, but would also like to know if it's currently possible to install OFED drivers on Proxmox 7. Would OFED for Ubuntu 21 work?

Apologies to resurrect an old thread... What was the exact process to install the Ubuntu 21 OFED drivers on Proxmox 7? Many thanks

Any luck with installing Mellanox OFED on Proxmox 7? We have many ConnectX-4 25Gb cards that perform poorly on Proxmox 7...

I'm also having issues with poor performance using Mellanox ConnectX-4 25Gb SFP28 cards on Proxmox 7. Have you had any luck installing an OFED driver? How about the one intended for Ubuntu 21?
