Advantages of Migrating Data Center Networks to 400G

    • 1. Increased Bandwidth and Scalability: Migrating to 400G transceivers provides a substantial boost in bandwidth, empowering data centers to efficiently manage the ever-increasing volumes of data generated by today's applications and services. This transition enables data centers to scale their networks effectively, ensuring they can accommodate future growth while maintaining optimal performance levels.

    • 2. Enhanced Network Performance: By leveraging 400G transceivers, data center networks can attain lightning-fast data transfer rates, resulting in reduced latency and enhanced overall network performance. The expanded capacity of these networks facilitates seamless handling of bandwidth-intensive tasks, including real-time data analytics and high-resolution video streaming.

    • 3. Optimal Resource Utilization: Migrating to 400G empowers data centers to optimize resource utilization by consolidating their network infrastructure, streamlining operations, and reducing complexity. By leveraging higher-speed connections, the need for multiple lower-speed links is minimized, resulting in simplified network architecture and decreased power consumption. This consolidation enables data centers to achieve a more streamlined and cost-effective network environment.

    • 4. Future-Proofing: Embracing 400G technology empowers data centers to future-proof their networks, positioning them at the forefront of technological advancements. With the ever-growing data demands, 400G networks provide a solid foundation for seamless scalability and robust support for emerging technologies like virtualization, cloud computing, and the Internet of Things (IoT).

Migration Options

This solution leverages the 400G DR4/400G XDR4 high-speed network connectivity technology to upgrade the rates of the core and spine switches to 400G while maintaining the leaf switch rate at 100G. By doing so, it significantly enhances the internal data transfer speeds within the data center, ensuring seamless and efficient communication. Additionally, this approach enables a gradual and cost-effective upgrade of the data center infrastructure, alleviating the financial burden on customers.

      • 1. Leaf-TOR <500m, using 400G DR4 and 100G DR1 connection

        Migration Options-1

      • 2. Leaf-TOR <2km, using 400G XDR4 and 100G FR1 connection

        Migration Options-2


By leveraging the power of 400G transceivers, data centers can meet the ever-growing demands of modern applications and services while laying a solid foundation for future growth and innovation. Embrace the migration to 400G and unlock the full potential of your data center network.
