AI is driving a large improve in information middle workloads, with IDC predicting that information technology will develop at a compound annual progress fee (CAGR) of 40.5% by 2027. Gartner expects that the usage of generative AI fashions will affect over 90% of organizations to pursue hybrid cloud environments by 2027. This can put a major pressure on information middle interconnect (DCI) networks that transport information between distributed, hybrid, and cloud information middle architectures. Historically, transporting information between geographically distributed information facilities required leasing high-capacity circuits from service suppliers or investing in devoted optical transport networks. Nevertheless, DCI connections over darkish fiber utilizing coherent pluggable optics supply an modern various that reduces each the fee and complexity of connecting information facilities to assist AI functions.
The monetary burden of conventional DCI options
Sometimes, service suppliers use their fiber networks to supply DCI companies to enterprises. These leased circuits are sometimes 10G hyperlinks or a number of 10G hyperlinks that assist conventional DCI functions, akin to catastrophe restoration and enterprise companies. They’re additionally used to assist 100G hyperlinks for extra demanding functions—akin to information middle mirroring and high-speed information aggregation and connections—to cloud companies. The adoption of extra data-intensive functions is pushing DCI capability in the direction of high-bandwidth 400G and 800G connections. Because the price construction of DCI is often primarily based on bandwidth utilization, this shift creates a brand new monetary burden for enterprises. Prices can rapidly multiply as they want extra circuits to assist elevated capability calls for.
The benefit of leased darkish fiber for DCI
Leasing darkish fiber is a compelling choice for enterprises to mitigate the monetary impression of DCI as capability necessities improve. Darkish fiber are optical fiber cables which were laid however aren’t but “lit” with information transmissions by a service supplier. By leasing these fibers, enterprises can create their very own personal community, gaining management over their information site visitors with out the recurring prices related to bandwidth utilization below conventional service fashions.
The State of Maryland is a superb instance of the usage of darkish fiber for DCI. The state’s Division of Data Expertise operates a 3,300-mile community and turning to darkish fiber resulted in annual financial savings of over $111 million, with an ROI of 871%. The advantages of leasing darkish fiber and constructing a personal community lengthen past price financial savings. Darkish fiber offers enterprises scalability, which is important within the age of AI. As their information wants develop, enterprises can scale their bandwidth with out ready for his or her service suppliers so as to add extra capability. Darkish fiber additionally boosts enterprise safety postures by offering full management over the information traversing the community, which reduces publicity to exterior threats.
Integrating IP and optical networks for DCI
Conventional DCI architectures are constructed on a devoted optical community layer that requires investments in optical transponders and line methods to transmit information site visitors throughout the fiber. Enterprises can scale back the fee and complexity of DCI with Cisco Routed Optical Networking. It’s a confirmed and standardized resolution, utilized in hyperscale DCI environments and in service supplier networks. Greater than 300 prospects worldwide have adopted Routed Optical Networking to extend capability whereas lowering vitality consumption and prices.
Routed Optical Networking permits optical wavelengths to be delivered immediately from the high-capacity ports in routers or switches within the information middle. It simplifies the community by changing devoted transponders with industry-standard coherent pluggable optics, high-density routers, and easier optical line methods. This results in a lower-cost community design. For point-to-point DCI options, enterprises can deploy coherent pluggable optics with Cisco Nexus switches to break down the switching and optical layers at Layer 2. For networks supporting extra advanced companies, they’ll converge routing and optical layers onto a single IP/Multiprotocol Label Switching (IP/MPLS) community the place all switching occurs at Layer 3.
The advantages of Routed Optical Networking for DCI
What does all this imply to an enterprise stability sheet? Fewer elements imply diminished CapEx, a smaller {hardware} footprint, and decrease energy and cooling prices. In response to evaluation by ACG Analysis, Routed Optical Networking can lower the overall price of possession for DCI functions by a staggering 48%, whereas decreasing CapEx by 60% and general environmental prices (energy, cooling, and flooring area) by as much as 83%. However it doesn’t cease there. Routed Optical Networking additionally contributes to:
- Community simplification: Convergence of the IP and optical layers streamlines the planning, design, activation, administration, troubleshooting, and determination of community companies.
- Automation and assurance: A single end-to-end automation platform reduces errors, improves resiliency, simplifies repairs, and accelerates the launch of recent companies.
- Community efficiency: Routed Optical Networking helps high-speed connectivity for demanding functions like AI site visitors or long-distance transmission.
- Dependable transmission: Strong information transmission within the coherent pluggable optics adapts to completely different community and fiber infrastructure situations for enhanced transmission reliability.
DCI for AI-ready information facilities
Cisco has launched a set of accelerated compute, community cloth, and hyperscale cloth options to deal with the information middle necessities of AI—from the coaching of subtle fashions to the widespread use of inferencing. As the quantity of knowledge powering AI surges, the necessity for cost-effective and scalable options to interconnect information facilities has by no means been better. By leasing darkish fiber and adopting Routed Optical Networking, enterprises can be certain that their mission-critical networks are able to assist the unprecedented calls for of AI at the moment and tomorrow.
