Data Center Construction Speeds Up, Showing Four Major Development Trends In 2021

- Jan 25, 2021-

The construction of the data center will still be high-speed in 2021. In 2020, the data center will become a "core member" of the new infrastructure. Alibaba Cloud announced in 2020 that it will invest 200 billion yuan in data center construction in the next three years; Tencent has quickly followed up with 500 billion yuan and also focused on investing in data center projects; Kuaishou announced that it will invest in the construction of the first big data center in Ulan Qab. Aroused great attention; China Mobile plans to invest more than 100 billion yuan in three years to build a mobile cloud, and the data center is also the focus. According to CCID Consulting's data, by 2021, China's big data market will reach 492.03 billion yuan. Central South, North China, and East China will still account for the largest proportions. Hefei, Fujian, Guangdong, Zhejiang, Jiangsu, Shanghai and Beijing will continue The city is accelerating the pace of building a digital economy. In 2021, what trends will emerge in the construction of data centers?




   Accelerate the migration to the cloud




  Complex North Asia Technical Director Wu Jian believes that in 2021, data centers will accelerate the deployment of emerging technologies. Important global trends such as the growing demand for high-performance networks, improved management efficiency, and the impact of the COVID-19 epidemic will all have an impact on the deployment of emerging technologies in data centers. The increase in take-out orders and the sharp decline in retail shopping in physical stores have greatly promoted the growth of online sales and have also had a significant impact on data centers.




   Under non-"normal" circumstances, large and small enterprises are migrating to the cloud, and regardless of the epidemic situation, this trend will accelerate in 2021. Companies that were on the sidelines before, are now quickly turning to a cloud-based model to operate their businesses. Many companies that arrange for employees to work from home have adopted cloud-based applications to implement remote office strategies, while retailers are following the pace of industry giants and shifting sales tools to the cloud.




   Another major trend related to cloud computing is the accelerated adoption of private cloud infrastructure. Previously, the industry generally believed that everything would eventually be transferred to the public cloud. But judging from the needs of many companies, they prefer to store sensitive information such as finance and healthcare in a private cloud. At the same time, there are some applications that cannot be converted to the public cloud at all. Those who operate and maintain large data centers also find that the price of private clouds is lower than that of public clouds. Therefore, most enterprises will adopt a hybrid form of public and private clouds to manage their applications and data, which will also become an industry standard practice.




   Increase the adoption of artificial intelligence




   Converged artificial intelligence (AI) applications have always been the general trend of data centers, and this trend shows no signs of slowing down in 2021. Although apps launched during the epidemic may continue to be used after the epidemic is over, the above trends do have a strong correlation with the COVID-19 epidemic. AI is used to promote the development of safety and security applications, such as automatic body temperature measurement, contactless authorization, payment and control systems, and human flow monitoring. AI is also used in building management systems such as HVAC control and lighting.




   By processing large amounts of data or ML (machine learning) training sets, it is possible to develop complex AI algorithms. For example, millions of faces can be scanned to provide an algorithm that can fully understand the nuances of human expressions. After the algorithm is created, it can be responsible for responding to a large amount of real-time information, such as facial twitching, frowning, and pupil dilation.




   AI/ML data is usually stored in a huge data pool, and dedicated servers equipped with accelerators, such as GPUs, are very suitable for processing AI/ML tasks. Data center networks are increasing bandwidth to provide large enough data pipelines for these systems to enable the development of economical and efficient AI tools.




   IoT deployment will surge




  As companies strive to achieve better facilities and personnel management, IoT applications are rapidly increasing. Newer connection protocols such as LTE-M and Zigbee allow wireless sensors for temperature, water consumption, space occupancy, HVAC control, and other applications to be used, and Power over Ethernet (PoE) enables Wi-Fi access The unified high-efficiency of all applications such as point-to-surveillance cameras becomes possible.




   The Internet of Things provides critical data. For example, the Internet of Things can promote the optimization of manufacturing, making the application of AI in process control a trend. To realize communication between machines, the data communication system must achieve very low latency. Latency is also the main consideration when deploying new smaller distributed systems or edge data centers (edge data centers are used to support applications and services in close proximity). This trend is accelerating the deployment of distributed network facilities to support a large number of edge data center applications.




   With the continuous increase of IoT applications, the amount of data generated is expected to increase exponentially. Perhaps the most effective way to process IoT data is to process the data locally at the edge. According to Gartner's forecast, by 2025, about 65% of servers will be deployed in edge data centers.




  Promote the development of single-mode fiber




   The need for rapid response by remote workers and shoppers will drive the widespread adoption of single-mode fiber. Although single-mode fiber has existed for a long time, its deployment will accelerate further as data centers gradually adopt 400G Ethernet in 2021. Although affected by the epidemic, the deployment speed of 400G will slow down in 2020, but this situation is expected to improve in 2021.




   In addition, the capacity of the data center will continue to grow, and its efficiency is bound to continue to improve. Since the previous generations of copper cables have reached the upper limit in terms of speed and transmission distance, more efficient network switching equipment is required, and the use of "fiber to server" is promoted. This is precisely the optical fiber network that drives the increase in bandwidth of network equipment and optical devices. s reason. The goal of the IEEE 802.3db working group is to reach 100Gbps, 200Gbps, and 400Gbps speeds for server connections, which will help to develop VCSEL-based low-cost optical devices (multimode fiber optic transceivers) for short-distance applications.




   In 2021, adapting to and meeting the needs of remote office workers and customers, making facilities safer, more efficient and achieving performance improvements will become a key trend in data centers. As the industry continues to change, companies implementing these plans will be at the forefront of the digital wave.
