XS728T - LAG Load balancing
Hello all, I configured a LAG to my server with 4 10G ports with LACP. My storage server is running Windows Server 2019 with NIC Teaming with LACP. The LAG is up and running, but when I try ...
You were right...
It was some kind of intersection in the src MAC addresses.
I made a new test by:
- changing the switch's load balancing back to src-dst-mac.
- changing the mac addresses of four of my servers to:
f0-00-00-00-00-00
f0-00-00-00-00-01
f0-00-00-00-00-02
f0-00-00-00-00-03
As I have a defined number of servers that will connect to the storage, I can change their MAC addres to garantee a certain load balance in their traffic.
But the initial question persists, WHY the web interface of the switch does not allow me to change the load balancing mode?
Thanks,
Andre
My test was done by copying 40GB and 500GB from 4 to 10 server to the storage.
So there were different MAC addresses on the copy.
What I don´t understand is why it wasn't sending those different src mac addr packages in differents links of the LAG. When I changed it to use the ip load balancing mode, it started sending packages on the other links.
When using just mac load balancing I reached a 4Gbps average for the copies.
With the ip load balancing I reached a 16Gbps average with 20Gbps+ spikes for the copies.
I am not sure, but I think the switch' mac load balancing is broken or it is wrongly using the "dst mac" as the load balancing source.
The mac address of the 4 servers test copying files to the storage ended with:
Server 1: 19-94
Server 2: 1C-D4
Server 3: 19-50
Server 4: 17-D0
Maybe, if their driver allow, I will try to change their MAC addresses to end with 01,02,03,04 and try the test again.
