They use Tofino as the networking switch. But Intel is discontinuing Tofino so I'm wondering what does future upgrade path look like for Oxide? Would they consider something like a p4 programmable DPU as the replacement?
- flumpcakes 3y agoOxide racks curren use AMD CPUs and and after buying Pensando AMD now offer P4 DPUs. I would hazard a complete guess and say maybe a move from Tofino to Pensando is on the cards for future networking revisions.
- osti 3y agoCompany where I work at is evaluating Pensando DPUs and they are very powerful.
- wmf 3y agoDPUs can't really replace switches. Maybe they could just keep using Tofino for the next N years until something better comes along.
- osti 3y agoIt kind of can if you want to add programmability to your switches. So on top of traditional switches, you can add a cluster of DPUs in order to add networking functionalities to your switches. Microsoft has done just that. https://www.usenix.org/system/files/nsdi23-bansal.pdf https://www.usenix.org/system/files/nsdi23-bansal.pdf
