NIC teaming / link aggregation Hyper-V 2012 R2

Hi there,

Is possible to team NICs at the host running Hyper-V and in fact aggregate all the bandwidth? For example, get 4x 1GB NICS and in fact have 4GB network to a switch?

Thanks!

Yes, group all your nics, and select Team at the Host OS level.

NICs do not have to be the same make or manufacturer.

I heard many things about the NIC teaming not actually working as a single 4GB link, but doing only traffic for each single IP stream per NIC. Are you sure it can aggregate all of them in this way at the Hyper-V level (host) and then a single VM can make use of this wider bandwidth to send a single file transfer at 4GB for example?

That's how Microsoft advertise, it, I would also configure the switches as a trunk port, and "bond" all four ports into a channel group.

I'll try it myself tomorrow, got 2 server coming for testing so let's see how it goes :)

So, from all I've been reading, the NIC teaming works as a load balancing as it can't aggregate traffic from a single server, to another server for example using a simple file transfer. I would like to have a single transfer using both NICs, in case using 2GBIT, but it seems be physical or virtual, this can't work and the only way to use more bandwidth is if there is another client sending information from a different IP/connection so basically the server would be making 2 connections, one to each server and each at 1GB limit.

Is that in line with your knowledge or is there any other way of getting a single file transfer split between 2 connections so it can maximize the bandwidth?

I found another article now that again put more questions than answers:

http://blogs.technet.com/b/josebda/archive/2012/05/13/the-basics-of-smb-multichannel-a-feature-of-windows-server-2012-and-smb-3-0.aspx

Windows Server 2012 includes a new feature called SMB Multichannel, part of the SMB 3.0 protocol, which increases the network performance and availability for File Servers.
Increased throughput. The file server can simultaneously transmit more data using multiple connections for high speed network adapters or multiple network adapters.
At least one of the configurations below:

Multiple network adapters
One or more network adapters that support RSS (Receive Side Scaling)
One of more network adapters configured with NIC Teaming
One or more network adapters that support RDMA (Remote Direct Memory Access)

So, it seems it is actually possible because of SMB 3.0, but I could not get it to work yet
