I have just added a new 10GB network card to my Unraid server (previously it had 2 1GB NICs) and have seen Unraid pick it up straight away and add it into the bond. Seems to be working fine. However, I am questioning if I have this set up in the most optimal way.

 

I currently have no other servers with a 10GB NIC but will have this soon and will then be able to test so this post is just to gather some thoughts and information from people that have experience with this just to check my own understanding. I also plan to remove the 2nd 1GB NIC now I have the 10GB NIC working.

 

I have set binding mode set as “active-backup (1)” and all 3 NIC are seen in the bond; eth0, eth1 and eth3 (being 1GB, 1GB and 10GB NICs respectively.

 

 

With “active-backup” mode I would have expected one NIC to be used exclusively and a second NIC only to be used if the first failed. But what I’m seeing is the first old 1GB NIC being used most and the new 10GB NIC being used a little, so that is unexpected. The second 1GB NIC (eth1) is on a "private" test LAN so there's no traffic on that.

 

 

 

Is this because everything connecting to the Unraid server is currently doing so only at 1GB?

 

Ideally, I assume I would like the 10GB interface to be used for most things and the 1GB interface only to be used as a backup? Is my assumption correct and how do I set this in Unraid.

If what you are really trying to accomplish is to make the 10Gb your default connection for unRAID, you need to make sure it is eth0.  unRAID will always use eth0.

 

Under Settings --> Network Settings you can set which NIC is eth0
