Would buy something like this as a device you can connect via pcie to your server.
No need to have switches and servers in your rack anymore, every server is a switch and every switch is a server with a 192 threads CPU. Insane.
- wmf 2y agoIt ends up crazy expensive and complex to configure but go for it.
- Asmod4n 2y agoI bet Nvidia is selling something like that but with only 2-4 ports for the same price as a 48 port switch...
- wmf 2y agoAFAIK DPUs are only ~$2,000 but if you put one in each server it adds up to far more money than a traditional network. They're really not intended to replace TOR switches.
- karma_pharmer 2y agoAll the switches in this series except the one in this review actually have two separate boards inside with a PCIe-over-cable connection between them. For example the SN2700 here (the sleeved cable in the third photo; you can't see the connector from the angle it's taken from): https://ipng.ch/s/articles/2023/11/11/mellanox-sn2700.html https://ipng.ch/s/articles/2023/11/11/mellanox-sn2700.html The cable has a SAS (SFF-8087) connector on each end. I bet you can replace it with an SFF-8087-to-Oculink cable: https://www.amazon.com/chenyang-SFF-8611-SFF-8087-PCI-Express-Slimline/dp/B07DFHH4SK https://www.amazon.com/chenyang-SFF-8611-SFF-8087-PCI-Expres... and a PCIe-to-oculink card like one of these: https://www.amazon.com/Ableconn-PEX-OL153-OCuLink-SFF-8612-Adapter/dp/B08DR17F5F https://www.amazon.com/Ableconn-PEX-OL153-OCuLink-SFF-8612-A...
