MicrosoftGabrie van Zanten thanks for your feedback.
Hyper-V in clustered environments require more attention to detail and deeper knowledge. Again Windows Server 2025 and Azure Stack HCI will reduce this once again. If users adopt the features. Like Network ATC etc.
No help if they do things like they did since.
I am often hearing what you second here. Other hypervisor solutions appear to be more plug and play, let it be ESXi, Nutanix etc.
Does it mean the Networking Performance is optimal out of box? Let's pretend few care to optimize and as long things are stable they might not care.
What I am aware out there are VMware and Hyper-V clusters with RDMA support but none of these are use. Given the existing topology of storage networks, and this requires supported switches or not, what a waste of performance I would say. Cannot tell anything how competition handles other offloadings, like RSS.
I do hope if any of the network settings you mentioned were off, they would've signaled them by now.
I would recommend, you should check these yourself. Don't trust they are looking at all things from the tons of logs.
Suboptimal settings remain suboptimal settings, not necessarily turn up in a logfile pointing that out. Easier for S2D and Azure Stack HCI as SDDC logs and environment logs are more comprehensible (imho).
Gabrie, when you are in such an unfortunate situation that an issue cannot be reproduced, I would always recommend taking a second look from your end. I have had these cases that never seem to find a remediation. It's utterly frustrating. That's why I am posting here in lenghts. Not to defend and saying things cannot go wrong but to raise the awareness of complexity and where having a second look is worth the time.
Hope that this is overly helpful.
Would you have more details about This is a limitation that's addressed with Windows Server 2025 and Azure Stack HCI 22H2 or newer?
Yes of course it's been highlighted in a video of last year's Ignite by Jeff. I believe the video is in the OP. Also second time in the Windows Server Summit 2024. Check this out, please. CPU Compat flag will do what you are used to with VMware ESXi.
