@markos Just so you know, my previous post sent me down the path of researching RSS and RSSv2 in Windows Server 2022. As far as MS documentation is concerned, they think it’s on by default with 2022. As far as Nvidia is concerned, it’s not. You must set the registry key to enable it. See my post here: ConnectX-6 Dx with RRSv2
With that in mind, I enabled this key for all Connect-X 6 Dx NIC’s on 4 out of the 5 Hyper-V cluster nodes for one of our clusters.
This is what running the Mlx5Cmd.exe -OidStats looks like on our HyperV node 1 after enabling the RssV2 registry key for both NIC’s and rebooting:
This is what running the Mlx5Cmd.exe -OidStats looks like on our HyperV node 2 without enabling the RssV2 registry key for both NIC’s:
This may not fix the issue, but I’m extremely hopeful. If this doesn’t work, turning off RSS entirely may be the next step. Generally, the NIC resets show up for us about 2 weeks or so after our last reboot. In 2 weeks, I’ll be testing again to see if the problem still exists. I would expect it to exist on node 5 of our cluster, and the other 4 nodes to not have the problem.
I’ll report back in 2 weeks after I see how this goes.
