Hello!
I am building a Hyper-V cluster with SCVMM 2012 SP1 and 4 nodes. The storage is SMB 3.0. everything is on Windows 2012.
I have created a Logical Switch with a 4 NICs (1 network card with 4 ports Intel PRO/1000 PT Quad). This logical switch has 3 network virtual adapters: Cluster, Storage and Live Migration (separate VLANs are used).
Everything works and the network is fully compliant. The problem I am facing is that storage speed is too slow. I am utilizing only 1 NIC during file transfer (I know this is a childish test but it is a good starting point). The transfer is stable ~112MB/s
Interesting part is next: if I go to network settings on a cluster host and create a network interface with different VLAN the same file is being copied with the speed of 180-200 MB/s (better but I would expect 300MB/s from 4 NICs).
The port Profile is set to LACP and TransportPorts.
Why is that? Why do I have a poor performance through the Hyper-V switch?
Thank you!
