Hyper-V cluster - network design

Hello,

I try to get new recommendations about hyper-v clustering network configurations. I want to discuss my ideas.

When creating a 2 node hyper-v failover cluster with

4x 1Gbit each node
2x 10Gbit each node
Storage connected via FC, so I am not asking about storage traffic

My preferred network design:

  1. deactivate 4x 1Gbit

  2. create SET team of 2x 10Gbit with managementOS = true
    This is easy and I can use 10Gbit for management (fast backups) + guest traffic + CSV + LM

Are there any downsides? I could use "Set-SmbBandwidthLimit -Category LiveMigration -BytesPerSecond XXXMB" to limit the Live Migration traffic. I can limit backup traffic with the backup software. All I can see is that the cluster does only have 1 network, so the metric is the same for all traffic. How can I take care of the csv traffic in this case (maybe with PFC and ETS or is this not applicable)?
I could also create two vNICs on top of the SET team (and make use of SMB Multichannel) and choose this for CSV and LM...

Or would you still suggest to use different networks for MGMT, LM, CSV and MGMT and make use of the 1Gbit adapters?

Thank you for discussing
