While you search on-line, use e-mail, watch a video, or click on on a advisable hyperlink, you then would possibly’ve used hyperscaler networks that assist the whole lot from cloud-hosted functions to neural networks with AI/ML. Functions are producing and ingesting information at great charges, which implies information facilities are dealing with large visitors masses. In keeping with the Worldwide Vitality Company (IEA), for each bit of knowledge that travels the community from a knowledge heart to finish customers, one other 5 bits of knowledge are transmitted inside and amongst information facilities (“Knowledge Centres and Knowledge Transmission Networks”, November 2021). IEA estimates that 1% of all international electrical energy is utilized by information facilities, with rising power use over previous years, rising 10%-30% per yr (IEA 2022).

Challenges

To deal with these monumental calls for, cloud suppliers add extra servers with larger capacities leading to extra information being pushed into the community– each inside and out of doors of the information heart. With out correctly scaled infrastructure, the community turns into a bottleneck. And that’s when customers put up about their sub-par experiences.

Given the present environmental and geopolitical issues, power effectivity and attaining internet zero carbon emissions are more and more changing into high priorities for cloud suppliers. However as information facilities must scale and assist extra bandwidth-hungry functions, the query is how a lot energy, area, and cooling are wanted whereas going inexperienced?

Throwing bandwidth on the drawback would possibly look like a straightforward repair till the tradeoffs seem.  Rising capability includes extra gear, energy, area, and cooling to keep away from potential overheating, or dangers with working out of rack area. For instance, scaling to over 25Tbps capability in a leaf/backbone community utilizing 32x400G switches at 1 RU every would require six switches. That’s roughly 3000 watts consuming 6RU area, to not point out the 36 followers wanted for cooling.

Resolution

However, if we might construct large capability in a small footprint, we might tip the associated fee and efficiency scales again in favor of the suppliers and assist the atmosphere. What would possibly sound close to unattainable is now out there and transport, with the most recent member of the Cisco 8100 Sequence, the Cisco 8111-32EH that’s able to 25.6T capability in a compact 1 RU kind issue (see press launch). With ultra-fast QSFP-DD800 ports utilizing a Silicon One G100 25.6T ASIC, the Cisco 8111 can assist 64x400G ports in the identical 1 RU kind issue at roughly 700W.

That’s as much as a 77% discount in energy, 83% discount in area and variety of followers to realize the equal capability utilizing a number of 12.8T ASIC switches, primarily based on inner lab research 1 (see Determine 1).

Not solely can cloud suppliers profit from main operational value financial savings and decrease their energy payments, however this discount additionally interprets to important financial savings in carbon emissions with ~9000 kg CO2e/yr in Greenhouse Gasoline (GHG) discount (primarily based on inner estimates). And the ability financial savings may very well be used so as to add extra revenue-generating servers that assist cloud suppliers develop their enterprise.

The huge power financial savings are a results of our in depth investments, akin to Cisco Silicon One. For instance, utilizing cutting-edge 7nm know-how helps enhance energy effectivity, whereas using 256x112G SerDes helps ship 25.6T in a single chip for main energy/area/cooling discount.

With excessive density QSFP-DD800 modules, we’re introducing new 2x400G-FR4 and 8x100G-FR modules that allow excessive density breakouts to 100G and 400G interfaces, supporting 64x400G ports or 256x100G ports in simply 1 RU.

These modules will allow larger radix for next-gen community design and double the bandwidth density of the platform footprint with environment friendly connectivity over copper, single-mode, and multi-mode fiber. The QSFP-DD800 kind issue can assist subsequent technology pluggable coherent modules that will require larger energy dissipation and nonetheless present the effectivity and cooling capabilities.

By delivering ground-breaking improvements, akin to for public cloud information facilities, with a lot larger densities in compact kind components, we will help prospects drastically scale back operational prices. Primarily, we’re redefining the economics of cloud networking by cost-effective scale.

Improvements with Cisco 8000 Sequence

The Cisco 8000 portfolio is used for mass-scale infrastructure options to ship excessive efficiency and effectivity, together with for cloud networking with hyperscalers and web-scale prospects adopting hyperscale architectures (see Enabling the Internet Evolution). The Cisco 8000 portfolio consists of the next merchandise and cloud use circumstances:

  • Cisco 8100 Sequence merchandise are mounted port configurations in 1 RU and a pair of RU kind components which are optimized for web-scale switching with TOR/leaf/backbone use circumstances. This product line consists of 8101-32H, 8102-64H, 8101-32FH and now Cisco 8111-32EH. The 8100 might be provided as disaggregated methods utilizing a third-party NOS, akin to Software program for Open Networking within the Cloud (SONiC), along with built-in methods with IOS XR.
  • Cisco 8200 Sequence merchandise are mounted port configurations in 1 RU and a pair of RU kind components, together with Cisco 8201 and Cisco 8202 that can be utilized for the Knowledge Middle Interconnect (DCI) use case to hyperlink information facilities utilizing IP transport. These are provided as built-in methods with IOS XR.
  • Cisco 8800 Sequence are modular methods, and embody Cisco 8804, Cisco 8808, Cisco 8812, and Cisco 8818 that can be utilized in a wide range of use circumstances akin to super-spine, high-capacity DCI and WAN spine use circumstances

Extra particulars might be discovered within the Cisco 8000 information sheet.

The Cisco 8000 provides our prospects the pliability to select from a variety of kind components, speeds throughout 100G/400G/800G ports and a wide range of consumer optics, built-in methods, and disaggregated methods utilizing SONiC for open-source networking use circumstances (see Rise of the Open NOS), and leveraging Cisco Automation portfolio.

At Cisco, we meet prospects the place they’re, which implies offering resolution decisions that match their use circumstances and necessities to allow the proper buyer outcomes.

Greater networking capability is now attainable with out dramatically larger energy payments and inefficient cooling options, which ends up in quickly increasing the carbon footprint. Clients can save prices, assist the atmosphere, and decrease person frustrations by higher experiences. As a substitute of selecting between going inexperienced or scaling massive, we’re serving to cloud suppliers do each with Mass-scale Infrastructure for Cloud.

Open Compute Mission (OCP) International Summit

The Open Compute Mission (OCP) International Summit is assembly this week (Oct 18th – 20th) in San Jose, and this yr’s theme is “Empowering Open”, which we totally assist by open collaboration with the open-source group. Two years in the past, on the OCP International Summit, we first launched Cisco 8000 supporting SONiC with each mounted and modular methods, and proceed to collaborate with the OCP group to develop open options. For instance, on the OCP 2021 International Summit, Meta and Cisco launched a disaggregated system, the Wedge400C, a 12.8 Tbps white field system using Cisco Silicon One (see press launch).

This yr, we’re showcasing our 8100 portfolio with 8101-64H, 8102-32FH, 8101-32H together with the brand new 8111-32EH and QSFP-DD800 optics at OCP. We may also be displaying SONiC demos with totally different use circumstances, akin to twin TOR and with modular methods utilizing the 8800. Cisco may also be talking on the Government Speak, that includes Rakesh Chopra on “Developed Networking, the AI Problem”.

Go to our sales space at Open Compute Mission (OCP) International Summit this week to see our newest improvements.
