We received two servers with hyper-V 2012R2 free for our project this week, and we need to create an SMB failover. I'm not familiar with multiple network card setups, as we had our previous servers with a single NIC.

How can I configure properly the settings in PowerShell to transfer the data over multiple network connections?


You need to add MPIO feature and configure multipathing. Here’s the detailed guide about SMB, find the MPIO configuration: https://www.starwindsoftware.com/blog/part-2-smb-3-0-file-server-on-free-microsoft-hyper-v-server-2012-r2-clustered.

Here’s an info about MPIO as well http://www.itprocentral.com/mpio-on-hyper-v-server/.

Also, make sure you don’t use LACP with the iSCSI because of possible latency issues.
