Hello everyone,
Disclaimer: as this is my first Post and English is not my mother tongue feel free to educate me on misplaced words or Posts.
I recently bought an Atom based miniPC for use as the NAS in my network
and run light 24/7 tasks to reduce power consumption. The existing AMD box should be used for Temporary heavy workloads and use the storage of the new Atom box.
After setup there was no link on the sfp+ ports.
I tried to forcing negotiation speed on both servers, but couldn’t figure out how to do it on scale.
Then i started to try out different combinations of hardware i have. These tests i summarized in the following Scearios.
I also tried Scenaroi1 with another scale box in the basement used for backups and connected using fiber. Same symptoms on Server1.
Setup:
Server1: Qotom Q20332G9-S1
builtin intel x553 4Port SFP+
Truenas scale Dragonfish-24.04.0
Server2: Custom build AMD box
pcie Chelsio Communications Inc T320 2Port SFP+
Proxmox 8.2.2
Scenario1:
When i connect Server1 and Server2 with DAC from 10GTek on Server 2 the Port light up. On Server1 nothing happens.
Server1 dmesg shows
ixgbe 0000:0b:00.1 eno2: detected SFP+: 4
Server2 dmesg shows
[75275.709949] cxgb3 0000:2b:00.0 enp43s0: unknown PHY module inserted
Scenario2:
When connectiong 2 Ports on Server1 the connection gets established.
Server1 dmesg shwos
