Problem Network with Switch Embedded Teaming (SET)

[matou801]

Hello,

I have a problem on a Hyper-V cluster. 

Here is the detail :

3 X DL 380 Gen 10 with 768 Go RAM connectd with 2 HPE3PAR (50To) on remote copy and  Multipathing on switchs Aruba 3810 with DAC network cables. The cluster hosts around 200 VMs

OS : Windows 2016 with rules Hyper-V, managed with System Center Virtual Machine Manager.  

Network server hyper-v01:

Live Migration : 10.8.8.1

Cluster HeartBeat : 10.7.7.1

Network storage 01 : 100.0.0.1

Network storage 02 : 200.0.0.1

Network Active Directory cluster : 10.2.180.1/24 (connected on Internet)

Backup Network (DPM) : 10.9.9.1

And two ethernet adapter configure with Switch Embedded Teaming (SET) for VMs 

Sometimes the vms are disconnected.
I desactivate the network cards of the vms and it works again.This problem occurs on all 3 servers but not at the same time.
Have you ever had this kind of problem? I can't find anything in the windows logs. HPE tells me that my servers are all OK, drivers and SPP up to date. I have desactivate VMQ, but without success.

Network interface :

I can't see where to look to find the fault. Could a VM crash the network teaming ?

Thank you for Help

Matt
