SMB 3 Multichannel: File transfer speeds between multiple Gbit links and one 10Gbe link

Hi,

one question about SMB3 multichannel that has been bothering me today and for which I could not find a definitive answer after some extensive research online is this:

What actually happens if a SMB3 multichannel compatible client (e.g. Windows 10, 8 etc.) with two (or more) gigabit NICs tries to transfer files to / from a SMB3 mulitchannel compatible server (e.g. Windows Server 2012R2) connected via 10Gbe to the same network, e.g. via a switch offering both gigabit and 10Gbe ports? Will the client be able to fully saturate all the gigabit NICs like it actually would do in case of the server having multiple (two or more) gigabit links? Or will SMB3 multichannel not work in this case, as client and server have network adapters of different speeds?


I am aware that SMB3 multichannel will not work with network adapters of different speeds on the same client, e.g. a client with a 100Mbit and 1Gbit NIC installed. But what about the client - server scenario explained above? Is SMB3 multichannel 'intelligent' enough to saturate multiple, slower NICs on the client side knowing that the fat pipe on the server side can handle it?


Thank you!
