Networking problem with shared nothing live migration over SMB 3.0

-

hello!

my basic setup atm consists of 2 windows server 2012 r2 nodes, network configuration basicly done discribed in video: http://www.it-cast.de/hyperv/hyper-v-unter-windows-server-2012-r2-preview-teil-4-die-livemigration/

so 2 nodes have 4 port 1gbit adapters , configured ports 1 , 2 on different subnets , directly attached between nodes. here's thing now, if move data (shared folders) between nodes pumped 230mb/sec , both links used smb3.0.

i full link usage when move vm in status "shutdown". if try move vm in status "running" both links used well, time there magic 800mbit (or maybe 1 gigabit, dont gigabit speed single link either, while live migration) barrier cannot overcome. (the 800mbit split evenly on number of links)

i searched 5 days until , cant find error in setup.

(for curious, rss enabled 8 queues , far smb 3.0 goes, setup seems working)

thanks in advance, dont know how further problem.

kind regards

rico
