Does anyone have any recommendations on a "relatively" cheap 400G QSFP-DD switch? One requirement is to be able to configure each port to fanout to 2x200G. I noticed that on some of the tofino based edgecore switches, they only fanout to 4x100G.

I am trying to find the NMLXCLI vib file. I need to use this cli tool to set spoof checking off and trust on in vmware. This needs to be done in order for VLANs, SRIOV and ESX to live happily ever after! If I use PCI-PT instead of SRIOV, it works. Unfortunately, I need to use SRIOV and need to...

STH just posted an article on these nic cards. I am trying to get some clarification on the specific cable to connect a QSFP-DD switch to one of the OSFP cx-7 nics. There are 2 issues that we encountered: 1. the nic side requires an OSFP "Flat top" connector not the "Fin top" that is normally...

I had a few motherboards that I was using to test my latest project (Nvidia Connectx-7 pcie gen5 nic). This project required a pcie 5.0 motherboard. While I was waiting on a real server board (intel sapphire rapids/amd genoa), I used an amd 7950x with a few different motherboards. I had 2...

I will be receiving some pmem 200 optane dimms shortly and wanted to understand how to set the mode MM, AD etc for the chips. I am assuming this might be in the bios somewhere but not sure. This will be on an ice lake system on a supermicro motherboard. I also have a few other systems but...
