NIC teaming / link aggregation Hyper-V 2012 R2

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 :)

Trying this guide now:

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?

it seems okay
