Problem With ixgbe (SFP+ module for networking)

[Dany Kurniawan]

Hello everyone.
I'm new on proxmox. So please forgive me if any mistake i made.

I have deploy a new proxmox 5.3 installation.
I use QuantaGrid D52BQ-2U server which include 2 Ethernet and 2 SFP+ ( Intel® Ethernet Converged Network Adapter X520-SR2 ) module on PCI card.

When i have done proxmox installation, i just see the 2 ethernet card showing in network config file.


When i do execute command modinfo ixgbe


When i do lspci | grep Intel :


When i do dmesg | grep Ether :


Do i missed something?

hmm - From the (partial) output I see the following:
* enp103s0f0/enp103s0f1 - are the 2 X722 NICs at PCI-address 67:00.0/67:00.1 - these use the i40e driver.
* from the lspci output it could be that these X722 use Twisted-Pair, a.k.a. RJ45 cabling

The output you pasted does not indicate that there is any X520-SR2 (which would use the ixgbe driver) in the system

* check `dmesg` for potential problems
* do you see the card present in the BIOS/UEFI of the system?
* does it get recognized with a (Linux) live-cd?

>> when i execute dmesg | grep ixgbe, i don't see any ixgbe output there. does ethernet support for 10G connection? i thought that 10G just for SFP.

>> what should i grep from dmesg sir?

* do you see the card present in the BIOS/UEFI of the system?
>> i see on bios same as lspci | grep Intel . 67:00.0 Intel Corporation Ethernet Connection X722 for 10GBASE-T and 67:00.1 Intel Corporation Ethernet Connection X722 for 10GBASE-T
>> No other ethernet/networking card showed up

* does it get recognized with a (Linux) live-cd?
>> when i install proxmox, it just recognize 2 NIC adapter. Like result in lspci | grep Intel

What else do i need to investigate regarding this sir?

Ethernet is a layer 2 Protocol and can be transported over many links (SFP+, Twisted Pair, ...) - and 10G over Twisted Pair (RJ45, CAT5/6/7) is possible (and AFAIK becoming more common).

Then it seems that either the X520-SR2 is not installed correctly or broken - maybe try to put it in another PCI-E slot

If the card does not show up somewhere in the BIOS (or with another OS (Linux LiveCD, FreeBSD, Windows)) - it is not related to PVE

Hello.
I have fixed that problem.
The problem is because i have 2 module on that server. The ethernet (twisted pair - RJ45) and ethernet (SFP module)
When i remove the ethernet twisted pair, the config file of ethernet SFP showed up.
I thought that this problem is on the misplaced position of ethernet.
