Over the past decade, ever-changing data communication technologies have continued to break the limits of speed and space constraints on Earth. Today, we can send a video blessing to friends on the other side of the ocean through WeChat, or broadcast a romantic wedding in Sanya, Hainan. In this era of Internet of Everything, data communication technology has advanced by leaps and bounds, especially in data centers for storing, processing, and transmitting data. Its rapid development, continuous iteration, and constant redefinition of people's lifestyles. Let's make an interesting analogy. Building a data center is like designing a smart city. The key to its success lies in the organic connection of a new generation of information technology and physical components to build a simple, efficient and reliable data city foundation.
At the moment of the Internet of Everything, fixed and mobile Internet traffic data traffic and data storage needs are growing at an incredible rate. According to Gartner, the number of Internet of Things (IoT) connected devices is expected to exceed 20 billion by 2020. Cisco Cisco's Visual Networking Index predicts that global monthly mobile data traffic will increase eight-fold between 2015 and 2020 to 30.6 EB. The growing demand for fixed and mobile data traffic is driving the increase in the number and size of data centers. Another notable trend today is the rise of public cloud services, which means deploying up to 10,000-scale hosts to build a very large data center, compared to a common data center of hundreds of servers. The relevant hardware level enhancements are required to match the requirements to address the following challenges.
§ Forward-looking change: data center accelerated iterationThe speed of transmission to the data center is like a change in the way the city travels. The influx of data traffic has prompted major service providers to continually revisit the upgrade of data transmission speeds in data centers. Data center equipment has increased data transmission speeds from 10 Gbps to 25, 40, 50, and 100 Gbps. As connector and cable assemblies continue to evolve for higher speed products, today's cutting-edge technologies are quickly becoming popular. For example, TE's Sliver internal cable interconnect system is capable of providing high-speed broadband interconnect solutions from 400Gbps to 800Gbps, and has been recognized by the Onboard Fiber Optic Module Alliance (COBO) as a new data center standard to address the challenges of increasing data transfer rates. . At the same time, designers are bound to face more complex signal transmission path designs. In the new world of data centers, decentralized architecture is driving innovation in data traffic processing, and the ever-increasing number of connections between racks and servers is driving the use of leaf and spine architectures that require larger, higher densities. Switches and a large number of internal and external ports. System architects must carefully consider multiple factors including size, weight, power, cost, and performance to ensure the best combination of choices, especially for cables that are often overlooked, and upgrades to accommodate hardware performance improvements. In order to give full play to the various upgrades brought by hardware upgrades.
Xu Suxiang, Senior Manager of Technology Applications, Asia Pacific, Data Concentration and Terminal Equipment Division, TE ConnecTIvity said: "At present, the global broadband development speed is growing at a geometrical level: from 1Gbps to 10Gbps for about 5-10 years, and then to 25Gbps for about 2-3 years. Time, then upgrade from 25Gbps to 100Gbps for about 2 years. The speed of its iterative update is beyond our imagination, which requires electronic components companies like TE to continuously improve our innovation speed and keep up with the pace of the market. We are required to have forward-looking research capabilities and market predictions. I expect the transmission rate to move forward to 400Gbps."
§ Flexible and compact: enhances spatial densityThe utilization of human settlement space is a major issue that needs to be paid more and more attention as the population continues to rise. Similarly, when designing a living environment for data signals, engineers naturally need to consider how to use space efficiently under the trend of steep traffic. An important measure of the strengths and weaknesses of a data center design is whether it can balance the gap between the spatial density of server growth and the high-performance expansion of the data center. Imagine that if you can configure multiple independent server nodes in a compact chassis, you can not only reduce its space consumption, but also have a flexible storage and sharing infrastructure, which requires a stronger density for each hardware unit. .
In particular, the backplane of the data center provides core support for today's emerging data center applications, and performance limitations on the backplane reduce overall system speed. Because of this, TE's STRADA Whisper interconnect system is revolutionary in design, simplifying and improving backplane design while maintaining signal integrity and saving onboard space, eliminating the need for engineers to redesign the backplane or the middle at no cost. The backplane enables efficient next-generation system upgrades to support current and future performance needs.
§ Innovative design: energy and heat optimization upgradeThe use of ultra-large-volume servers and the increase in transmission rate are inevitably accompanied by the doubling of power consumption and heat dissipation requirements. Therefore, power cable configuration, green energy conservation and power risk management have become an important issue in data center operations to help data signals create a safe, energy-efficient and livable “cityâ€. Data center power and cooling related issues are the same as speed requirements, which determine the design and implementation of the system. Over the past decade, the power consumption of a single rack (and the resulting heat loss) has risen dramatically, leading to two interrelated problems: providing higher power and addressing the cooling of power and active electronic components in crowded enclosures. Because of the current required in the big data center and in the physical structure of the rack (and the board connections in each rack system), many cables and associated connectors are needed to meet the power path design. For a single connector, even small contact resistance and voltage drop (IR loss) will result in reduced power efficiency and increased heat dissipation (I2R), so the temperature rise at the connector must be maintained at a moderate level (typically below 30 °C). To ensure safety and performance. In addition, the ever-increasing demand for connectors that support the "hot plugging" of the board (ie, unplugged or plugged in when the power is turned on) poses further challenges. If the connector does not have the best contact materials and characteristics, it will cause power supply timing and contact fatigue problems.
TE's latest microQSFP is recognized as a new standard in data center and wireless communications applications. One of the big factors is that this product has 30% better heat dissipation than the traditional standard QSFP28. Its revolutionary design is almost The entire panel is placed in the device's available airflow and significantly increases the cooling efficiency of the connector and all other internal components while also providing 100G transmission speed over a conventional 10G I/O interface size range.
Chinese characteristics: the time and place also need people andCompared with other countries such as Europe and the United States, due to China's large population, in densely populated areas, the gap between demand for service resources during peak hours and general time will be very large. One of the most obvious examples is the annual “Double Eleven†shopping carnival, where hundreds of millions of buyers are eager to click on “confirm†bids. Through the technology of cloud computing, realizing the concentration and sharing of resources, meeting the large traffic demand in special time periods, and supplementing the resources of idle time to other required applications will be a very beneficial change, which is more suitable for China's national conditions. In addition,
Because the data center occupies a large area, it is often built in an area with complicated terrain and harsh environment. This requires more hardware equipment to withstand various challenges and maintain efficient, safe and reliable operation.
Future data communication: everything is possibleFuture data communications will enable faster transfer rates, more powerful data exchange networks, and more seamless real-time communications, turning the seemingly whimsical scene into a real-world application.
In fact, the future is not far from us. At this year's World Mobile Communications Conference (MWC), more than 20 influential companies in the industry announced that 5G new radio technology will be deployed on a large scale in 2019. This means that after two years, the average consumer will get a faster data transfer experience, one year earlier than previously expected. "5G will bring high-speed, low-latency, high-capacity advantages, detonating a series of terminal and industry changes, subverting people's life scenarios, such as mobile applications, virtual reality, autonomous driving, remote surgery, etc." Vice President of TE ConnecTIvity Jason Merszei, General Manager of the Asia and Europe Region of the Data and Terminals Division, and Chairman of the Joint Committee of the TE China Business Unit, said at the 2017 MWC site, “In short, future data communications, everything is possible, and these pioneering physics The foundation is the backbone of the data from our connected world."
