M4300-x to Qnap with 4 ports

[Jaimix77]

Hi,

I've cretead a Lag (mode 7, best perfomance of all that I tried) with 4 ports spf+ for Qnap connection. But when I simulate data transfer from other computers, I see in log that only 3 ports got the most of the packages and 1 of them got a almost zero packages . Any ideas ?

LAG does not imply an kind of link load balancing. As long as the aditonal link is not required, you won't see any usage.

Is the NAS (and are the computer(s) involved in the test) able to reach 30Gb+ - assuming you talk of SFP+ with 10 Gb - bandwidth?

Testing woith four (or more) PCs?

I've got  4 Pc's with 10 Gb connection each. And the test was reading / writing 32 GB from the QNAP at the same time !

Which QNAP NAS model, what storage configuration, SSD cache or tiered storage?

What bonding mode configured on the NAS and the switch?

What does the switch LAG status show?

What does the NAS bonding status show - also check # cat /proc/net/bonding/bond* and post the output.
