Oxide and Friends
Unshrouding Turin (or Benvenuto a Torino)

Totally. Yeah. So when we end up designing for kind of not absolute density, but trying to get the best density in a fixed power budget, which because, you know, unlike the hyperscalers, we're not basically building a power plant next to every new DC. Yeah. that that's where it gets a little more challenging.

Oxide and Friends
Unshrouding Turin (or Benvenuto a Torino)

And so we're trying to work with folks to figure out, you know, Hey, if I don't need, say all of the arm cores that show up there, or let's say I didn't run with DDR five, you know, where can I, what can I get? What can I, can I still get out of there? You know, how can we kind of change this from, you know, some of these parts are, and I don't remember what this one was, you know, or 50, 75 Watts.

And, you know, that's that, or, you know, maybe I, I play games and I say, um, you know, I've got a lot of SSDs, but maybe I don't need all of the IOPS, all those SSDs. So I can double up, you know, capacity instead.

And that gets me back some of the power and I can send that to the neck, but it's definitely, uh, we're not in a, you know, even with just increasing power for the CPU, I'm already trying to think about like, well, what do I do for folks who don't have all that power? If I've got 32 sleds, how do I, uh,

But yeah, overall, really good, really nice to see, excited to see that kind of P4 continue there and hoping someday we can find a way to make it make sense for us. But I think there's a lot of other folks who it does make a lot of sense for.

Oxide and Friends
Unshrouding Turin (or Benvenuto a Torino)

Sure, I'll see if I can do it justice. Effectively, the way I think about P4 is it basically is a programming language that you can use to compile a program that operates on the Nix data plane. And I think this is an important part because for a lot of these things, the value is to actually run at line rate.

So you've got 100 gig, 200 gig, 400 gig, especially with all these 112 gig 30s coming along. You basically can't necessarily treat that as a general purpose program that's coming in, DMAing everything back to normal, you know, to a normal core's memory and processing it and sending it back out. But instead, this kind of lets it process the packets kind of in line in that hardware receive path.

Actually, George, this is the pitch I've tried to make to them. Just because to me, it's like if you actually look at NVIDIA and what they've done with NVLink and basically buying Mellanox, at the end of the day, to really be able to you know, deal with that, what they're doing with ultra ethernet, it feels like you have a P4 engine. Yes. It's going to be a big change.

Take it from, you know, the Nick kind of two cert, you know, two port form factor to, you know, a switch ASIC and kind of dealing with power. But I think that if you really want to do well in that space, you can't rely on just like, hey, I'm going to convince Broadcom to let me pass through, you know, XGMI, you know, through my switch.
