400G network transformation

Under the wave of digitalization, data centers are facing unprecedented challenges and opportunities. The vigorous development of cutting-edge technologies such as artificial intelligence, cloud computing, big data, and 5G has promoted the exponential growth of data volume, placing extremely demanding requirements on the network performance of data centers. The limitations of traditional network architectures in terms of bandwidth, latency and scalability are becoming increasingly apparent, and it is difficult to meet the high-speed data processing, real-time analysis and operation requirements of modern data centers and next-generation applications. The emergence of the 400G network, like a ray of light, has brought new hope and possibility for the transformation and upgrading of the data center, which can not only completely change the performance of the data center, but also achieve unparalleled efficiency, scalability and reliability, becoming an indispensable key support in modern IT infrastructure.

The inevitable choice for data centers to move to 400G networks

With the acceleration of digital transformation, the data traffic carried by data centers is showing an explosive growth trend. The deep learning algorithm of artificial intelligence needs to process massive data samples for model training, and the real-time prediction and analysis of machine learning rely on high-speed data transmission. The widespread popularity of cloud applications makes enterprises and users have rising demands for data storage and access, and the commercial use of 5G networks has pushed the data traffic to a new peak. 5G technology not only enables ultra-fast mobile connections, but also promotes the widespread expansion of the Internet of Things, enabling massive devices to generate and transmit data in real time, greatly increasing the demand for data center bandwidth. According to relevant statistics, global data center traffic has increased several times in the past few years, and this growth trend is still continuing. In this context, the traditional 100G and 200G network architecture has been unable to meet the growing demand for data transmission, network bottlenecks are becoming more and more serious, congestion, high latency and low efficiency and other problems occur frequently, seriously restricting the performance of the data center and business development. Therefore, 400G Ethernet has become the next logical step in the development of modern data centers, which can effectively solve many problems faced by traditional network architectures and provide a solid foundation for the future development of data centers.

The emergence of 400G Ethernet is not only to cope with the explosive growth of data traffic, but also to meet the urgent needs of data centers for high performance, low latency and high scalability. It increases the data transfer capacity of each link by four times, enabling each link to handle 400 gigabits of data per second, which means a significant increase in data transfer speed, a significant reduction in congestion, and a significant reduction in latency. This high-speed data transmission capability enables data centers to more efficiently handle a variety of data-intensive workloads, whether it is real-time data analysis, artificial intelligence workloads, or bandwidth-intensive operations such as high-resolution video streaming, which can be more smoothly and continuously supported. In addition, the 400G network can also provide strong scalability for hyperscale data centers, with the extensive deployment of 5G and edge computing, data centers need to process an increasing amount of data and business types, and the large amount of distributed data generated by 5G networks requires high-capacity, low-latency connections between core and edge data centers. With its superior performance, 400G Ethernet can easily meet these challenges and achieve an efficient and scalable network architecture to meet the growing business demands of the data center.

Energy efficiency and cost optimization are always important considerations in data center operations. Compared to multiple 100G links, a single 400G link can not only provide higher bandwidth, but also significantly reduce power consumption and operating costs. By consolidating multiple low-speed links into a single high-speed connection, data center network infrastructure is simplified, network complexity is reduced, and power consumption is reduced, resulting in improved operational efficiency and a more energy efficient and sustainable data center architecture. This cost-effectiveness is not only reflected in the procurement and maintenance costs of hardware equipment, but also in the long-term operating costs of the data center, which provides a strong guarantee for the sustainable development of the data center.

400G networks lead the data center architecture revolution

Against the backdrop of growing data demands and the emergence of new services, data centers are undergoing a profound transformation. The core driver of this transformation is the pursuit of higher bandwidth, lower latency and higher scalability, and 400G Ethernet is a key driver of this transformation. A major shift in data center architecture is upgrading existing central offices by using CORD (re-architecting central offices as data centers) to bring data processing closer to end users. The concept was originally proposed by the Open Network Foundation to improve data processing efficiency and provide low latency services to end users. By turning the central office into a data center, data can be processed and stored closer to the user, greatly reducing the distance and latency of data transmission and improving the user experience. This architecture can not only meet the needs of OTT (over-the-top) service providers for distributed CDN (content delivery network), enabling them to more efficiently deliver high-quality, low-latency video content, but also pave the way for innovative applications with high latency requirements such as autonomous driving and intelligent manufacturing. The integration of edge computing significantly improves response times for critical applications, enabling data centers to better support the development of these innovative applications.

In addition to the change in CORD architecture, another major shift in data centers is the migration to 400GE infrastructure to accommodate growing data traffic. According to Omdia, the demand for 400G data center switches is driven by the growing popularity of 25G/50G server interfaces, which are critical for high-speed storage access and massive data processing. With the continuous development of data center services, data interaction between servers is becoming more frequent, and the access speed of storage systems is becoming higher and higher. The popularity of 25G/50G server interfaces provides strong support for the development of 400G networks. Although the market adoption rate of 400G ports is only 0.3% in 2020, it has grown threefold compared to 2019 and is expected to reach 11% of the market by 2025. This growth trend shows that 400G networks are gradually becoming the mainstream choice for data center infrastructure, and more and more data centers are beginning to recognize the huge advantages brought by 400G networks and actively upgrade and transform the network.
