What are some good ICX ES? Want to upgrade from Xeon Gold 6326 on Supermicro X12SPL Any cheap Stepping 6 out there? Or any other recommendations?

Bought 48 DIMMs, pending shipment :) will report back once I receive them

Ebay has some cheapish Raritan PX3-5464R-G1K2, they should be capable of individual outlet metering & switching iirc. Not sure whether they work with 120V though (weird North American grid...) There is also a single PX3-5453R available

Picked up my parcel from Jacob today. Only one card contained, as expected. I’m gonna return it

Not ONIE / System EEPROM I mean EEPROM in the fan modules / power supplies

@nasbdh9 do you know how to write to Mellanox SN2700 fan & PSU EEPROMs via I²C from Cumulus Linux? I need to mod some fan / PSUs PSIDs I did it via Onyx and mellaggra in the past, but I don't want to install Onyx just for that cumulus@cumulus:mgmt:~$ cat test.bin | sudo tee...

Geizhals description says „pack of 5“ quite clearly. But sometimes there’s a mismatch between the shops and geizhals. We’ll see

Ordered at Jacob, let’s see whether I‘ll actually receive 5 cards :)

Absolutely not. The public Mellanox switchdev driver has lots of features, but especially QoS / buffer allocation stuff for RoCE You can find release notes here: Home What if I told you that with the Mellanox internal SDK, those switches could even do MPLS? ;)

It can, but only with recirculation. That’s just one of the limitations. Check the Arista Feature Matrix for 7050X(3) vs 7060X to get an impression Tomahawk 1 has issues with FEC on breakout ports (no RS-FEC on 25G ports) Sadly, most Tomahawk 1 switches have the Atom. Other examples are Dell...

Same chip as 7060CX, DX010, Z9100, etc… But good NOS (JunOS). Not quite as good as Arista, but definitely A-Tier.

Depends what you define as „good“ Juniper QFX5200 (Tomahawk) are already around $500 Trident 3 switches below $500? Some models already are, but only Whitebox. Proper ones like Arista 7050X3 or Juniper QFX5120 below $500? We‘ll see. Mellanox SN2000 is not quite there yet.

There’s a reason why these switches are often comparatively cheap: The lack of a good NOS. SONiC is not a good NOS. OpenWRT does not run on any big enterprise network switch (okay, maybe Mellanox, because these have mainline Linux kernel support), and is not a good NOS. Oh and of course...
