Data Center LAN Migration Guide 3. Legacy three-tier data center W Up to 75% of tra�c E Figure 5: Juniper Networks 3:2:1 Data Center Network Architecture Juniper’s data center LAN architecture embodies these principles and enables high-performance enterprises to build next-generation, cloud-ready data centers. For information on Building the Cloud-Ready Data Center, please refer to: www.juniper.net/us/en/solutions/enterprise/data-center. Other Considerations 2. Juniper two-tier data center W Up to 75% of tra�c E Juniper’s data center fabric It is interesting to note that even as vendors introduce new product lines, the legacy three-tier architecture remains as the reference architecture for Data Centers. This legacy three-tier architecture retains the same limitations in terms of scalability and increased complexity. Additionally, migrating to a new product line, even with an incumbent vendor, may require adopting a new OS, modifying configurations, and replacing hardware. The potential operational impact of introducing new hardware is a key consideration for insertion into an existing data center infrastructure, regardless of the platform provider. Prior to specific implementation at any layer of the network, it is sound practice to test interoperability and feature consistency in terms of availability and implementation. When considering an incumbent vendor with a new platform, any Enterprise organization weighing migration to a new platform from their existing one, should also evaluate moving towards a simpler high performing Juniper-based solution, which can deliver substantial incremental benefits. (See Chapter 3: Data Center Migration—Trigger Events and Deployment Processes for more details about introducing a second switching infrastructure vendor into an existing single vendor network.) In summary, migrating to a simpler data center design enables an enterprise to improve the end user experience and scale without complexity, while also driving down operational costs. 14 Copyright © 2012, Juniper Networks, Inc. 1.
