SFP+ Cable Issues, Qbiquit and Mellanox

[Kevin Patrick]

Done.

I get the card Monday, probably late.

I’ll post back with results.

Thanks Bob

Bob,

While waiting for the new card (coming today) I heard back from QNAP. Apparently, they have the same UniFi switch I have and their test results are the same as mine. In their words, “not good.”

They suggested connect direct and retest. (same suggestion as yours, they just have a higher latency response time)

Though I do have to connect up to other devices (both wired and wireless) to this server. So I will still need a 10 Gbe switch. I’ve nothing but success with Netgear, so I’m wondering what you opinion is of Netgear’s GS110MX switch?

I changed out two things.

First I tried the new 10Gtek SFP+ cable. This cable is supposed to be compatible with the Mellanox driver in the QNAP network card. No change at all.

Next I replaced the network card in the server with the QXG-10G1T card.

I connected this card to the RJ-45 port of the UniFi 10 Gbe switch. No change at all.

Finally, I connected the iMac Pro directly to the new network card in the server.

I set the IP address manually on the server and the iMac Pro. However, QNAP complained about not having any DNS server address. I rebooted anyway, since with my limited networking knowledge, I didn’t think this should matter for this test.

No change at all.

Of everything I’ve tried I simply cannot get the performance numbers to change.

However, when I went to check the Jumbo Frame settings the server I discovered that the only Jumbo Frame option for this new network card was 1500. No other option was available.

(insert you favorite frustration expletive here)

Am I missing something thats preventing me from changing the Jumbo Frames settings?

Bob,

I have a call scheduled with QNAP tomorrow. I’ll let you know how that goes.

This was scheduled after they got back to me regarding the Jumbo Frame issue. They told me to update FW and that would fix the Jumbo Frame setting issue. It didn’t.

[Bob Zelin]

did QNAP help you ?
If they did not, I can help you.

Hi Bob,

Executive summary of QNAP call, “It’s broke. We’ll get back to you.”

After installing the RJ-45 card both you and QNAP suggested, I ran into the problem of not being able to change the Jumbo Frame setting on the card. 1500 and only 1500 was selectable. The point of today’s QNAP support session was to fix this. Which they didn’t. It’s been esculated. Again. So, the direct connect performance was the same as the performance going throught the UniFi switch.

You’ve recomended this card, so I’m guessing you’ve had success with this card. How can it be that I can’t?

I suppose it’s possible that QNAP broke the Jumbo Frame setting in the current release.

I’d like to take you up on your offer, but I don’t want to waste your time.

I’m not sure which is going to give out now. My desk or my forehead.

[Bob Zelin]

It’s not broken. They are loading in the wrong firmware version.
Exactly what is it going to take for you to contact me privately ? Do you want me to send you money ?
