Windows Server LAG with Netgear XS708E

Hello, I have a question for NIC teaming under Windows Server 2016. I wanted to Team two 10 GbE lanes with a Netgear XS708E and my Server with a intel x540-t2 card. On windows I selected LACP with dy...

    Hi Picmention

     

    You can use the XS708E and have  inbound and outbound load balancing , however please make sure that when you configure the Microsoft teaamin you choose : Switch-dependent teaming with Generic or Static Teaming as described below:

     

    • Switch-dependent teaming. This configuration requires the switch to participate in the teaming. Switch dependent teaming requires all the members of the team to be connected to the same physical switch.[1] There are two modes of operation for switch-dependent teaming:   

                          o  Generic or static teaming (IEEE 802.3ad draft v1). This mode requires configuration on both the switch and the host to identify which links form the team. Since this is a statically configured solution there is no additional protocol to assist the switch and the host to identify incorrectly plugged cables or other errors that could cause the team to fail to perform. This mode is typically supported by server-class switches.

     

    Hope it helps!

HI Picmenton

 

Thanks for letting us know that the LAG is currently working and good to know that you can see traffic incoming and outgoing for the different issues.

 

I think that there are different ways that you can tune it to see if you can improve the results:

 

  • Enable Jumbo frames on switch and NICs
  • Change the Hashing Algorithm to Dynamic or Address Hasing on the Microsoft teaming configuraiton
  • Test using ohter tools to make sure that the bootleneck is on the Network ( iperf)

 

Hope it helps!

 

Regards

Hello again,

I tried some different settings on my Server and its Intel card. Now I reach 17 Gbit/s in some tests with iperf. It looks like the results varied from test to test bit I think it is a normal behavior from the LAG's "load ballancing". Thanks again!

    Thanks for letting us know Picmention that's a great achievement :)

     

    I am sure that with some other protocols with less overhead you will be able to reach even a better performance.
