Summary
Today’s data center is a vital component to business success in virtually all industries and markets. New trends and technologies such as cloud computing and SOA-based applications have significantly altered data center traffic flows and performance requirements. Data center designs based on the performance characteristics of older technology and traffic flows have resulted in complex architectures which do not easily scale and also may not provide the performance needed to efficiently meet today’s business objectives.
A simplified, next-generation, cloud-ready two-tier data center design is needed to meet these new challenges without compromising performance or security. Since most enterprises won’t disrupt a production data center except for
scheduled maintenance and business continuity testing, a gradual migration to the “new network” is often most practical. This guide has identified and described how migration towards a simpler two-tier design can begin at any time and at various insertion points within an existing legacy data center architecture. These insertion points are determined by related trigger events such as adding a new application or service, or by larger events such as data center consolidation. This guide has outlined the design considerations for migration at each network layer, providing organizations with a path towards a simplified high-performance network which can not only lower TCO, but also provide the agility and efficiency to enable organizations to gain a competitive advantage by leveraging their data center network.
Juniper Networks has been delivering a steady stream of network innovations for more than a decade. Juniper brings this innovation to a simplified data center LAN solution built on three core principles: simplify, share, and secure. Creating a simplified infrastructure with shared resources and secure services delivers significant advantages over other designs. It helps lower costs, increase efficiency, and keep the data center agile enough to accommodate any future business changes or technology infrastructure requirements.
Additional Resources
Data Center Design ResourcesJuniper has developed a variety of materials that complement this Migration Guide and are helpful to the network design process in multiple types of customer environments and data center infrastructures. On our public Internet website, we keep many of these materials at the following locations:
1. Data Center Solution Reference Materials Site:
www.juniper.net/us/en/solutions/enterprise/data-center/simplify/#literature
At this location you will find information helpful to the design process at a number of levels, organized by selectable tabs according to the type of information you are seeking—analyst reports, solution brochures, case studies, reference architecture, design guides, implementation guides, and industry reports.
The difference between a reference architecture, design guide, and implementation guide is the level of detail the document addresses. The reference architecture is the highest level organization of our data center network approach; the design guide provides guidance at intermediate levels of detail appropriate to, say, insertion point considerations (in the terms of this Migration Guide); and implementation guides provide specific guidance for important types of network deployments at different tiers of the data center network. Implementation guides give customers and other readers enough information to start specific product implementation tasks appropriate for the most common deployment scenarios, and are quite usable in combination with an individual product’s installation, configuration, or operations manual.
