It’s not daily you get to work on merchandise that proceed to evolve so rapidly that earlier than you end speaking about one machine the following era comes out. Nevertheless, with Cisco Silicon One™ that’s precisely what we’ve performed.
We lately introduced our 19.2 Tbps P100 piece of routing silicon and I needed to spend a while going over what it means from a system perspective.
Cisco Silicon One P100—In a category of its personal
There are a number of forms of routing silicon accessible in the marketplace right now from third-party silicon suppliers to full system distributors. This silicon covers quite a lot of market wants however broadly talking routing silicon breaks down into silicon that’s constructed for core, peering, and aggregation markets versus these specializing in broadband aggregation. If we check out all of the silicon presently accessible in the marketplace, it’s clear that Cisco Silicon One is in a category of its personal, and nonetheless right now there’s no routing silicon that achieves increased bandwidth, even than our authentic Q100 introduced again in 2019. Since then, we rolled out the Q200 with increased bandwidth and decrease energy consumption than the Q100. At present, lower than 24 months from our preliminary Q100 launch and simply 12 months from our Q200 announcement, we launched the P100, additional rising our lead over the competitors. We imagine the Cisco Silicon One P100 is 2.6 occasions increased ethernet bandwidth than different routing silicon out there.
The Cisco Silicon One P100 builds upon the nice basis that we created with Cisco Silicon One however continues so as to add options, buffering, scale, and programmability enhancements whereas rising the bandwidth.
Determine 1. Routing silicon accessible in 2021
As a result of Cisco Silicon One gadgets can flexibly assign ports to be generic ethernet or a completely scheduled material, the Cisco Silicon One structure allows optimized fastened bins and modular methods.
Determine 2. Cisco Silicon One – Widespread structure throughout kind elements
This functionality is exclusive within the business, and it permits us to supply merchandise from a set field measuring only one rack-unit with a single piece of silicon, to an enormous modular chassis with many items of silicon, to a completely disaggregated chassis with much more items of silicon. That is all completed with a typical structure, SDK, and P4 forwarding code.
Which means that once we come out with a brand new piece of routing silicon, we allow our prospects to take pleasure in advantages throughout their portfolio and community.
If I attempt to oversimplify the impacts of the Cisco Silicon One P100 out there, we see that:
P100 allows excessive bandwidth fastened bins with 6–12 occasions much less silicon. This results in huge energy, area, and value financial savings whereas concurrently lowering latency.
P100 allows modular methods which are greater than 2 occasions increased bandwidth than the rest accessible in the marketplace, with the business’s first 36×800, 28.8 Tbps modular line playing cards, whereas considerably enhancing energy efficiencies of modular methods.
Determine 3. Cisco Silicon One P100 vs. competitors
Fastened field benefits
As a result of we will use a single piece of silicon to create a 19.2 Tbps, 24x800G, or 48x400G router we will drive a stage of effectivity remarkable within the business right now. The subsequent finest piece of routing silicon in the marketplace tops out at 7.2 Tbps.
Which means that you should use between six and 12 gadgets to construct an equal system. This distinction means Cisco Silicon One allows a smaller, decrease latency, extra power-efficient router on the system stage.
Determine 4. Cisco Silicon One P100 fastened field benefit
Modular line card benefits
Modular methods are constructed with a number of items of silicon. Primarily based on limitations on the faceplate, Printed Circuit Board (PCB), optics kind elements, silicon, and orthogonal connector densities, most system distributors produce 36x400G line playing cards with customer-facing 14.4 Tbps of bandwidth.
Utilizing our superior structure, coupled with 100G PAM4 Serializer/Deserializer (SerDes) know-how, Cisco Silicon One P100 allows line playing cards to push via earlier limitations in entrance panel optics, PCB applied sciences, and orthogonal connectors, leading to line card {hardware} that’s two occasions increased bandwidth than different modular line playing cards. When mixed with our 25.6 Tbps material ingredient, the Cisco Silicon One G100 is 2.6 occasions increased bandwidth than different material parts, so prospects can construct modular routers which are as much as 3 times increased bandwidth.
Desk 1. Cisco Silicon One P100 modular system bandwidth
The bandwidth enhance coupled with the facility effectivity of Cisco Silicon One drives important energy effectivity positive aspects in comparison with all different routing silicon out there.
Determine 5. Cisco Silicon One P100 modular line card benefit
Constructing the way forward for the web
Cisco Silicon One P100 allows the best bandwidth and most effective fastened field routers primarily based on a single piece of silicon. It additionally allows the best bandwidth modular line playing cards which are two occasions increased bandwidth than what will be constructed with our opponents’ silicon.
Cisco continues to validate the claims we made in December 2019 by proving the advantages of a completely converged structure constructed from the bottom up for the way forward for the web.
