What if you could reduce your routing and optical footprint while adding more capacity to expand bandwidth while simultaneously reducing costs? What if you had more visibility into your network and more control over how you wanted it to run at both the optical and routing layer? With the Cisco Intra-Data Centre and Enterprise DCI solution, you can do all that and much more.
The Intra Data Centre solution connects several enterprise data centres and then brings their traffic via a high-speed optical link to the closest colocation or peering point. Once the enterprise data centre is located in the colocation site, it can be managed by a single management system while configuration and provisioning can be automated when Cisco Network Services Orchestrator (NSO) orchestration is deployed.
Large enterprises today deploy backup data centres to ensure the reliability of their most critical data for continuity and corporate compliance requirements. Often multiple data centres are gathered and backhauled to the disaster recovery site where all data is replicated. The DCI must be robust enough to dynamically access all of the interconnected data centres, and in the case of a catastrophic event ensure that all the data is available and secure.
Across the globe, enterprises are turning to cloud-based services to share the data centre cost. Savvy colocation providers around the world are introducing valuable cloud exchange services to solve this growing need. Previously, enterprises had to cross the Internet on best effort links for their cloud services, but today colocation providers offer a direct connection to multiple cloud providers within the colocation site.
If a colocation provider offers a customer portal, with the Cisco NCS 1000 and Cisco ASR 9000 platforms and Cisco NSO simple provisioning of the network elements can be done via an API, keeping the colocation portal and network topology in place. If no portal exists, Cisco offers a colocation provider the Cisco Prime Services Catalogue or a third party application to help create a portal for that provider, making for an easy transition to provisioning through the Cisco NSO API.
It seems there’s no limit to the growth of network traffic. Per month, IP traffic is set to reach 278 exabytes and Internet traffic 235.7 exabytes by 2021. The average Internet user alone will generate 57.0 gigabytes of Internet traffic per month in 2021, up 139 percent from 23.9 gigabytes in 2016. By 2021, average broadband speeds will be a speedy 53 Mbps.1
Within data centres, global IP traffic is expected to grow at a Compound Annual Growth Rate (CAGR) of 27 percent between 2015 and 2020. This growth will be driven by the increasing Machine-to-Machine (M2M) traffic as well as the demand for higher bandwidth for cloud services; increasing digitisation; mobility; and the Internet of Things. Cloud traffic will nearly quadruple during the forecast period, representing 92% of data centre traffic by 2020. Data centre to data centre IP traffic will grow at a CAGR of 31.9 percent during that time, to 1,381 exabytes annually.2
It’s clear that this growth in network traffic will greatly impact all data centres globally. The challenge for large businesses and service providers will be to deploy infrastructure and solutions that maintain a high quality experience for employees and customers at the lowest possible cost. This will require a high degree of automation and intelligence; flexibility in resource sharing; solutions that promote greater density among existing transport resources and a long- term vision that embraces proactive measures instead of reaction.
Cisco Data Centre Interconnect (DCI) solutions are designed to simplify, automate, and optimise different types of DCI solutions―from intra-data centre campus, enterprise to data centre, disaster recovery, Metro DCI and long haul data centres connecting globally. Cisco provides the only DCI solution with a single operating system across both the IP and optical components of the network with the ASR 9000 Series and the NCS 1000 Series. This common operating system―IOS XR―offers several compelling benefits for the combined solution.
The pressure is on in data centres. Manual turn-up of optical wavelengths and services and configuration of gear will soon be the past. Automation and orchestration are the newer, better ways of provisioning, deploying and managing DCI solutions. With an automated services environment, you go from weeks to hours for deployment and change requests. Service providers in particular can see a big reduction in operational costs so their teams can focus on more productive and helpful networking tools.
IP advances such as Segment Routing can reduce your routing table size while also scaling the network. Newer optical advances such as Flexible Light Orchestration of Wavelengths let you pack more capacity into an individual fiber and balance the tradeoffs between capacity and distance. Do it using the current mesh Reconfigurable Optical Add/Drop Multiplexer (ROADM) network you have in place today.
Data centre footprint is also becoming challenging as data centres are crammed with servers and networking equipment, contributing to growing power and cooling requirements. The ability to reduce the networking footprint can go a long way towards lowering costs and using the energy more efficiently.
For DCI you need clear visibility into all of the packet flows, optical ports and DWDM trunks. Automation can help you correlate alarms to understand what actions are required. The Cisco automation environment along with real-time telemetry provide end-to-end visibility for more control and better management of services.
The Cisco Intra-Data Centre and Enterprise DCI solution is meant to interconnect traffic between local data centres and to facilitate various enterprise interconnect requirements. These include connecting gear in enterprise buildings throughout a campus and connecting enterprise data centres to colocation sites for routing to ISPs, national or international carriers and content providers.
The Cisco Intra-Data Centre and Enterprise DCI solution features secure, single point-to-point high-speed optical connections from one data centre to another. It has been a popular topology among cloud providers and Web-based companies due to its simplicity and because of the maximum capacity of a fiber that can be used between two links. The point-to-point architecture is also chosen by customers that don’t need or want protection and restoration at the optical layer. The network architecture features:
Cisco DCI solutions run on a single operating system ― Cisco IOS XR ― for routing, aggregation and optical transport. The software is packed with features representing over 15 years of global development and deployment. Cisco IOS XR is modular so that major features are available as independent packages. Industry-standard RPMs align update and upgrade procedures with those used in the data centre.
Cisco model-driven telemetry, available with Cisco IOS XR Software, is a new and improved approach to network monitoring. Data is streamed and captured continuously from devices with efficient, incremental updates. Model-driven telemetry is fully configurable using telemetry YANG models. You can precisely specify what data to stream, to where, and with what encoding and transport using just the models. With model- driven telemetry, you simply specify the YANG model that contains the data you want.
Model-driven telemetry opens up your entire operational space for fine-grained control. The increased visibility provided by the streaming telemetry push model enables the highly efficient techniques of segment routing for near real-time network optimisation.
