Hello everyone,

I have a test lab with 2012R2 Hyper-V host, vmm 2012 r2 and 2 vms with 2012 R2.

Host have 2 pNics 1Gbps. 

I've deployed logical switch to host and teamed adapters.

for vms i used 2 different port profiles:

1: Min Bendwidth weight 1

2: Min Bendwidth weight 100

The problem that Min Bendwidth weight have no impact on network bandwidth testing results (pic below).

Im using jperf for tests. Hyper-V host is jperf server and vms are clients.



How does the setting minimal bendwidth weight is really work?

Thanks.

Minimum Bandwidth Weight controls how much bandwidth the virtual network adapter can use in relation to other virtual network adapters. The weight describes how much bandwidth to provide to the virtual network adapter relative to other virtual network adapters connected to the same virtual switch.

As long as there are sufficient bandwidth available, you won't see any spikes between the two profiles here.

Thanks for replay.

But where does it take network throughput?

If it take higher throughput then adapter realy has then Minimum Bandwidth Weight mechanism will never start working.
