My board has PCIe gen 4 x1, but unfortunately there’s a really cheap card with 6 ethernet ports but PCIe gen 2 X8

Thanks

Alright thanks

I see. Thanks

I thought they were using the USB protocol. Thanks

Oh. I thought they were using USB. Thanks

PCIe to USB and back to PCIe like what the miners use? Isn’t that unreliable long-term?

I cannot see any decent PCIE X1 to X16 risers on amazon. Everything is USB based which I don’t want

There’s another situation. There are older (and cheaper cards) which are PCIe gen 2 x8. Unfortunately, pcie gen 2 x1 is not going to suffice. What would I have to do to get this older kind of card to work? Do you have any reliable PCIe x1 to x16 risers in mind?

It doesn’t need that kind of bandwidth. 6 gigabit ports cannot saturate pcie gen 3 x1 in terms of bandwidth anyway.

What do I do if the card is PCIe gen 2 x8 though?

I’ll likely go for a 4 or 6 gigabit port card, so PCIe gen 3 x1 is not a problem. Am I correct in understanding that the card will run at PCIe gen 3 X1 if I do this?

What can I do if the card is PCIe gen 2 x8? These cards from Silicom are really cheap on ebay

Technically the slot is PCIe Gen 4 x1, but I understand. TBH PCIe gen 3 X1 is fine too, that’s more than 6 port Gigabit cards can saturate anyway.

Even maxing out the ports won’t be a problem. Even 6 gigabit ports don’t saturate a PCIe Gen 3 X1 slot in terms of bandwidth. But will the card work at all if all the physical pins are not connected electrically to the slot?

The slot is open. I’m just wondering whether the card will work properly in that slot since all the pins won’t be attached. PCIe Gen 3 X1 bandwidth is more than enough for it

I don’t want to cut the card

The card only needs PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth. I was hoping to fit it into the slot since it meets the bandwidth requirements

How would I do it then? The card doesn’t exactly need PCIE gen 3 X4, at the most it needs PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth.

Considering I am the operations team, just goes to show how much I have left to learn. I didn’t know about the external-dns operator.

Unfortunately, my company is a bit strange with certs and won’t let me handle them myself. Something to check out at home I guess.

I agree with you about the LVM. I have been meaning to set up Rook forever but never got around to it. It might still take a while but thanks for the reminder.

Wow. That must have been some work. I don’t have these certs myself but I’m looking at the CKA and CKS (or whatever that’s called). For sure, I loved our discussion. Thanks for your help.

I am using a reverse proxy in production. I just didn’t mention it here.

I’d have to set up a DNS record for both. I’d also have to create and rotate certs for both.

We use LVM, I simply mounted a volume for /usr/share/elasticsearch. The VMWare team will handle the underlying storage.

I agree with manually dealing with the repo. I dont think I’d set up unattended upgrades for my k8s cluster either so that’s moot. Downtime is not a big deal: this is not external and I’ve got 5 nodes. I guess if I didn’t use Ansible it would be a bit more legwork but that’s about it.

Overall I think we missed each other here.
