I know hardware doesn't usually get attention on HN but this DPU trend is fascinating to me and I finally understand what Jansen was saying about GPU and the next innovation is in networking with DPU.

I wish I knew hardware better but I'm coming to the idea that an xTB nvme and ~25gb/s PoE pcie card in my gaming PC would be a sic always on device. Lots of server roles really just need a tiny IoT device but storage/backup/media you're talking NAS and I just don't want a big NAS around all the time.

So an always on network storage in my PC that's sometimes-on. Between NVME-of and pcie that should be doable I would have though. PoE from my router that's got a tiny UPS and that's pretty sick.

Maybe Valve should make it so everyone with a gaming pc it's re-downloading their steam library or running 2 computers just to open a file.

Basically you're talking about https://mikrotik.com/product/ccr2004_1g_2xs_pcie or https://www.solid-run.com/news/the-first-software-defined-dp... but I think a real NAS is cheaper.

Those are very cool thank you. Still need the host device to remain powered on however so not quite.

What exactly is that benchmark testing? Seems like a lot of cores to handle just 800 Gb/s; that is only ~12.5 Gb/s per core. Even with their ~19% headroom that is still only ~15 Gb/s per core. You can terminate encrypted transport multiple times faster than that and unencrypted transport 10x faster than that comfortably in software on regular cores.

They might be doing 800+800 which would be 30 Gbps per core.

Ideally they would run some kind of cloud vSwitch benchmark that includes encryption (e.g. ESP), encapsulation (e.g. GENEVE), routing, stateful firewalling, NAT, monitoring (e.g. NetFlow/sFlow), etc. It's a lot of work.
