Intel’s X-Lab: Tomorrow’s Network Happens Here
By
NIC Evolution

“Twinville will be used on our fourth-generation 10GBASE-T adapter product,” said Pete. “Our first-generation card here at the top was a single-port, 10GBASE-T adapter. It used the 82598, had a third-party PHY, and it came in right at the top of the 25 W limit for PCI Express. The PHY itself burned approximately 14 W of that power budget and required an active cooling solution. That product was introduced in 2007. We then ‘upgraded’ that 82598 MAC by coupling it with a second-generation, 65 nm 10GBASE-T PHY. With that single-port solution, we were able to lose the active cooling. Losing active cooling is critical for LAN-on-motherboard solutions. You don’t want more fans…although blue LEDs might be nice! Anyway, we called this the WWF heatsink because it almost looks like the WWF logo. That design gave us enough surface area to dissipate the heat without a fan, and the total power was significantly lower—about 16 W.

Then, using a similar 65 nm device, we were able to use the same active [PHY] heatsink but go to a dual-port solution. Total power bumped up to approximately 20 W, which is still lower less power than the first-generation device, but with two ports. It uses the 82599 media access controller and has less board complexity. There are fewer power components, for example.

And now, moving to our 40 nm device, Twinville, you can see that the MAC is integrated with the PHY. Actually, it’s not just one physical interface—it’s two. Also, it supports three speeds—100 Mb, 1 G, and 10 G—whereas the others only supported two speeds. And it’s expected to consume about 10 W. The Twinville we have in testing now uses an active heatsink, but by production it’ll be passive, just like the second-gen card.”

    Anyone else notice the Guy Fawkes mask in the background?

    It's existence is noted in the text for pic3, though I can only wonder why he has it. Is it good taste to associate yourself with 4chan and anon nowadays?

    I am not sure if I ever saw the sign to the X-Lab when working at Jones Farm, but I did always wonder what went on in the labs that were similar to it. They kind of looked like IT work rooms to me, though it makes sense to have a need for oscilloscopes, soldering irons, networking tools, etc. for certain R&D projects.

    In picture #4 (elephant arm) :D 

    Thanks Toms for this article.

    Awesome article, I just finished me BSEE degree and now work in an network company where I help engineer servers so this is right up my alley!

    This all started in 1990 with the creation of EtherExpress 16 by a handful of people led by a visionary leader, Steve Kassel.

    My guess is that it was just a fun-looking mask someone had brought to the lab, perhaps because they also enjoyed "V for Vendetta." (I did!) I'd wager that the X-Lab crew had no idea of the mask's fleeting association with 4chan's anti-Scientology protests, much less the religious motivations behind Fawkes's attempted regicide. Let's not accuse good people without cause.

    Excellent article Tom (Willam actually). Nice reading, informative and geeky, just the way I like it. Amazing to see that they transfer 76TB in just one test (500,000,000*1518*100). Good job!

    Yeah, I was stunned. I honestly expected some automated tests, maybe a few guys with scopes taking occasional signal readings -- NOTHING like what I saw. I'd assumed that a technology as old as Ethernet was pretty much a done deal and didn't require much hand holding at this point. I couldn't have been more wrong.

    Does this have a PHY made by one of startups like Aquantia or Teranetics or is it a Broadcom PHY.
    I think we will be running 10GbaseT LOM in most datacenters soon.

    You can buy them off of newegg, they use Teranetics PHY's (Logo under the heatsink).

    Can Toms quit with the galleries or add a '10 per page' mode? Clicking next and having the entire page reload 50 times and having to scroll down 50 times is stupid. It's like we're suck in 2001 web design practices.

    The question is... where is QAM in networks? Why not? Is there anyone from Toms taking this question?

    Fun, great, informative and geeky. Loved reading every second of it. A nod and a drink to those guys for sure! By the way, i have IE9 and i cant post comments with it, have to use firefox for it, just an FYI. Not a big deal as i use FF anyways, just testing IE9.

    I don't know why but the picture of the engineer staring deeply into the glass struck an emotional tone with me.
