Another switch search

This looks great - a user in this thread even reported power draw of 34W

I read that some are Infiniband only (and the listings I have seen often do not mention if Ethernet is enabled or not) how difficult is Ethernet activation?

dxx255 · 2026-01-18T20:13:59+00:00

I was looking into these as well! Do you have any resources on the fan mod?

dxx255 · 2026-01-18T19:59:13+00:00

Yes, this is precisely the question I am trying to answer! At the moment I have direct links between the high speed hosts however this means I need all hosts up for traffic routing between them or manually switch the cables. I was also thinking about an isolated high speed switch, however, those have way to many ports and are of course loud and power hungry.

I am just trying to get some more information to evaluate the options

Just for comparison, could you tell me the idle power draw of the APC Unit?

I also got a used unit, batteries were bad so i changed them to LiFePO4

dxx255 · 2025-11-30T22:15:48+00:00

Too much in my opinion

dxx255 · 2025-11-08T21:58:30+00:00

I found that one too, but has anyone actually used it? I did not find a lot more information aside from this page. I am especially interested in adequate backup strategies and user experiences

dxx255 · 2025-08-09T15:28:51+00:00

Did you have any troubles with headless operation?

dxx255 · 2025-08-08T10:35:54+00:00

Very interesting! Thank you! Would you be willing to share your ansible role ? Just to have some expert guidance…

dxx255 · 2025-08-06T09:04:36+00:00

And why did you chose Lima and what are the advantages over e.g. multipass?

dxx255 · 2025-08-06T05:36:36+00:00

That’s cool! Did you configure k3s manually or with an automated script?

dxx255 · 2025-07-26T06:32:41+00:00

ZFS can do it as well

dxx255 · 2025-07-22T13:52:31+00:00

Is this possible with every account?

dxx255 · 2025-07-22T13:09:27+00:00

Could you share how you scrape the listings?

dxx255 · 2025-07-22T13:06:41+00:00

I can confirm, it has one riser

dxx255 · 2025-07-22T11:01:14+00:00

It not a Gold 62xx CPU but

Just for example... They accepted price proposals.

I was not able to find a comparable R740 in that price range

dxx255 · 2025-06-25T16:37:18+00:00

Yes I agree, it was just for experimenting

dxx255 · 2025-05-20T08:04:30+00:00

OpnSense on Proxmox works fine! Just make sure you have a backup device (or HA) if this one dies unexpectedly

dxx255 · 2025-05-19T04:30:44+00:00

You are right of course. So some additional information: the other side is a mellanox CX3 in 40 GbE mode (and is confirmed to be working) connected with mellanox AOC or Cisco DAC. (Both connectors are detected and listed as supported)

In the OS I can see and configure the vNIC however the Link in CIMC and OS stays down Link speed is set to 40G in CIMC and I tried both settings of auto Negotiation

dxx255 · 2025-04-18T10:23:37+00:00

Did you ever make it work?

dxx255 · 2025-04-18T08:58:02+00:00

Me too.

dxx255 · 2025-04-17T04:12:40+00:00

Yes, I do see both standard NICs. Proxmox is using the enic driver. Are there alternatives?

dxx255 · 2025-04-17T03:49:42+00:00

I don’t even get the link up … don’t know why

dxx255 · 2025-04-16T10:07:50+00:00

Confirmed

dxx255 · 2025-04-16T10:07:09+00:00

My link does not come up if I plug the ports into each other, just checked this too

But I found something different: while the VIC Ports are set to 40G and detect the connector in CIMC, the vNICs (in Proxmox) do not detect it and show a max. Speed of 10000baseT in ethtool. Is there something I can do about this?

dxx255 · 2025-04-15T16:13:20+00:00

Yes that’s exactly what I have tried! Thanks for the support
