Try to stop all network interfaces that is not used in the moment with:
ifconfig xxx down

This should remove IP addresses that is not necessary.

On Windows side make the same - check for additional static IP addresses on all NIC's and remove them.
If the problems continues please provide output from:

Windows CMD:
ipconfig all
route print

NAS console:
ifconfig
netstat -rna

Hi guy's! Busy week so far.. so only could get to it now..

Disconnected everything, rebooted, connected the 10Gbe, used 'ifconfig *** down' on all but ix1, 1 ip listed.

so far so good.

(only connect 1 physical lead to your NAS people, even if it is the 'isolated' IPMI port on the server mobo you bought specifically to be able to remote access in the first #*! place..)

(tried setting IPMI in the uefi bios, no success)

Went on testing with iperf:

Code:
PS C:\Users\Matthias\Desktop\iperf-3.1.3-win64> .\iperf3.exe iperf3 -c -p 5201 -bidir
iperf3: error - unable to connect to server:

So the first measurement is when i still was on my Gbe copper lead on my desktop side. Changed it to 10Gbe fiber after that, and could reach anything, on with the 2-4 iperf test.

Yeah :smile:

tried hooking up the NAS directly to my desktop, no success.

Ifconfig on the NAS side:

ifconfig route print, did not work, but i could see the error 'interface route does not exist' error in the console.

Cutting it to here for today guy's!

To be continued..

did you mean netstat -r ?
Click to expand...
No, it went like i stated above.
I didn't do netstat, because of first error.

Then i went on re-connecting everything as it should be, and could do all requested commands.

I tried printing the output, but i didn't succeed..

Goddamn IPMI..

Going to try again later this weekend.

@sretalla ask because you mismatch the commands:
ifconfig -> list network interfaces on BSD/Linux
netstat -rna -> list routing information on BSD/Linux

ipconfig -> list network interfaces on MS Windows
netstat print -> list routing information on MS Windows

Your command:
ifconfig route print
is wrong and you receive expected error from "ifconfig".

Easiest way to eliminate the switch as bottleneck is to connect NAS and PC directly and you don't need to reconfigure anything. When you plug the fiber optic cable in PC and NAS ports directly you should have the link up and running (check the status from the NAS console) and should have access to the same IP address of the NAS as previously.

Hi all,

Tried all the above once again to find the culprit..
But however did not succeed in getting the NAS and PC connected directly.

It went as follows:

Checked all commands, when everything's up and running:

Next up, connected the module from my PC -> SWITCH, directly into the NAS.
Couldn't connect to the NAS IP.
Checked the Intel Proset adapter utility for the uplink itself, it was ok. (green light 10Gbe uplink)
Swapped out the modules again, no luck. Re-plugged the best combo.

re-did all the commands:

Glad i picked up a bit of navigation through the cli..

After scrolling through the outputs i noticed the following value's to be strange?
- PC IP (192.168.241.1)
- PC still having a persistent route? And they jump ip range?
Persistent Routes:
Network Address Netmask Gateway Address Metric
192.168.2.20 255.255.255.0 192.168.1.52 1
192.168.2.252 255.255.255.0 192.168.1.52 1

Also checked on the Windows 11 side of the story, booted a fresh copy of Windows 10. (reconnected everything to the SWITCH)
iperf show same results, starting in the low 1.2-3Gbe's to 6.5Gbe max throughput after a couple of runs.

So this should have eliminated every setting i did wrong on the Windows 11 side, but still was not able to connect directly tot the NAS nor achieve 10Gbe-ish.
Swapped the leads, but then the 10Gbe uplink in the Intel Proset Utility went dead.

Triple checked the console on the NAS side if the ip was still 192.168.1.33, it was the entire time.

I suspect my pc's IP range of 2 could be the answer? Than again, using the W10 machine with fresh network settings, that eliminates this possibility right?

Running in circles again..
Maybe your trained eyes spot something.

Thank you all

I think that the mystery is solved ;)

When you direct connect NAS and PC the NIC's are fine, the link is up and running, on NAS side you have proper network config but on PC side there is a problem.

Because the PC is configured to use DHCP for IP address assignment, there is no DHCP server on direct link and Windows assign IP address from Automatic Private IP Addressing space (169.254.0.0/16)

Code:
Ethernet adapter Ethernet 4:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::60e0:623:357e:602a%10
   Autoconfiguration IPv4 Address. . : 169.254.149.66
   Subnet Mask . . . . . . . . . . . : 255.255.0.0
   Default Gateway . . . . . . . . . :


with this IP address you can't access your NAS at 192.168.1.33

You almost find the clue but you looking on wrong network adapter:
Ethernet adapter VMware Network Adapter VMnet1 -> this is virtual adapter used from VMware

Code:
Ethernet adapter VMware Network Adapter VMnet1:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::12bf:4556:8040:1b7a%14
   IPv4 Address. . . . . . . . . . . : 192.168.241.1
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . :


You need to configure "Ethernet 4" with static IP address on Windows for testing direct connection between NAS and PC.
For example:
IP address -> 192.168.1.22
network mask -> 255.255.255.0

After the tests you can switch back to DHCP configuration on PC.

Soo... i was kind of hoping that the switch would be it, but than again not so much XD..

So next investigated with different combo's of SFP modules that work, same ballpark figures again.

Next on the checklist, i'd presume checking the firmware of both cards?
Or drivers?

Thanks again for the tips!

Or is my PCIe 2.0 x16 card not fully utilising the PCIe 3.0 x4 slot?

Checked the 2.0 specs, it runs at 4Gb/s per lane so x4 should be ok i think unless the change in PCIe spec creates overhead?

I think the PCIe version is not the problem.
I make some tests here on virtual Windows 10 and the strange thing is that I receive almost the same 6Gbps when I execute:

After this I try with iperf3 "-P" options for multiple streams:

[SUM]   0.00-10.00  sec  15.2 GBytes  13.0 Gbits/sec                  receiver


The SUM of the streams in my case are 15Gbps and on Windows Task Manager/Performance/Ethernet I see the same 15Gbps.

I'm not sure if iperf3 for Windows have limitations and can't reach max speed with one stream (execution without -P) but you can try to use "-P 4"

After this I try with iperf3 "-P" options for multiple streams:
Code:
iperf3.exe -c 10.10.10.10 -P 4

The SUM of the streams in my case are 15Gbps and on Windows Task Manager/Performance/Ethernet I see the same 15Gbps.

I'm not sure if iperf3 for Windows have limitations and can't reach max speed with one stream (execution without -P) but you can try to use "-P 4"

Yup, that's it!

Windows screenshot of the taskmanager with the X520 interface confirms:

note: added the following to iperf command: '-P 1', '-P 2', '-P 3'

So 10 Gbe confirmed working through the switch.

For the curious ones, i got to ' -P 30' till results got worse (due to cpu limits i figure, single threaded program?).
