  • The Importance Of Using Smart PDU In Data Center Rooms.
    The Importance Of Using Smart PDU In Data Center Rooms.
    April 18, 2023

    Data centers are essential components of modern businesses, providing the backbone for many of the services and operations that keep companies running. As such, it is critical that data centers be designed and managed in a way that ensures maximum efficiency and reliability. One of the most important aspects of data center design is the use of Power Distribution Units (PDUs). PDUs (Power Distribution Units) are used in data centers to provide power distribution and management. They are used to distribute power from a central source, such as a UPS or generator, to multiple devices in the data center. PDUs also provide remote monitoring and control of the power distribution system, allowing administrators to monitor power usage and adjust settings remotely. This helps to ensure that all connected devices are receiving the correct amount of power, while also reducing energy costs by eliminating wasted electricity.PDUs provide a reliable source of power to all devices in the data center, helping to ensure that they remain operational at all times. A PDU is an electrical device used to distribute power from a main source to multiple outlets or devices. It typically consists of a metal box with several outlets on one side and a power cord on the other. The PDU can be mounted directly onto a wall or rack, or it can be connected via cables to other equipment in the data center. In addition to providing power distribution, PDUs also offer protection against overloads and surges, as well as remote monitoring capabilities. The use of PDUs in data centers has become increasingly important over time due to their ability to provide reliable power distribution and protection from electrical problems. This is especially true for larger data centers, where there may be hundreds or even thousands of devices requiring power at any given time. By using PDUs, these devices can be powered reliably without having to worry about potential problems caused by overloaded circuits or surges in voltage. Additionally, since many PDUs come with remote monitoring capabilities, administrators can easily keep track of their power usage and make adjustments as needed. In addition to providing reliable power distribution and protection from electrical problems, using PDUs in data centers also helps improve energy efficiency. By distributing power more efficiently through the use of multiple outlets on each unit rather than relying on one large circuit breaker panel, less energy is wasted during transmission and cooling costs are reduced due to lower temperatures in the server room. Additionally, since many PDUs come with advanced features such as metering capabilities which allow administrators to monitor energy usage more closely, they can identify areas where energy savings could be made and take steps accordingly. Using PDUs also helps improve safety within the data center environment by reducing risks associated with overloaded circuits or surges in voltage which could potentially cause fires or other damage if left unchecked. Since most PDUs come with circuit breakers built-in which automatically shut off when an overload occurs, this helps protect both personnel and equipment from harm’s way while still allowing for reliable operation when needed. Finally, using PDUs helps reduce downtime by ensuring that all devices remain operational even if one outlet fails due to an overload or surge in voltage thus avoiding costly downtime for businesses relying on these systems for their operations.

Spring Festival", also known as "New Year", is a folk festival that integrates the removal of the old and the new, worshiping the gods and ancestors, praying for blessings and warding off evil spirits, family and friends reunion, celebration and entertainment, and food. Spring Festival has a long history and evolved from the ancient era of the first year of praying for the year's sacrifice. All things are originally from the sky, people are originally from the ancestors, pray for the year rituals, respect for the sky and the ancestors, and the beginning of the rewards. The origin of the Spring Festival contains a profound cultural connotation and carries a rich historical and cultural heritage in the inheritance and development. During the Spring Festival, various activities are held all over the country to celebrate the New Year, with strong local characteristics. In traditional agrarian societies, the Chinese New Year is of great significance and has given rise to a large number of folk cultures related to it. Although the calendar is different, the festive framework and many folk customs have been passed down throughout history. In modern times, people set the Spring Festival on the first day of the first month of the lunar calendar, but generally, the New Year does not end until at least the 15th day of the first month. The Chinese New Year is the first of all festivals and is the grandest traditional festival of the Chinese people. Influenced by Chinese culture, some countries and regions around the world also have the custom of celebrating Chinese New Year. According to incomplete statistics, nearly 20 countries and regions have designated the Chinese Spring Festival as a legal holiday for the whole or some cities under their jurisdiction. Spring Festival is one of the four traditional Chinese holidays, along with the Qingming Festival, the Dragon Boat Festival, and the Mid-Autumn Festival. The Spring Festival is a time to get rid of the old and bring in the new.

  • Sustainability Trends in Data Centers
    Sustainability Trends in Data Centers
    January 05, 2023

    Sustainability Trends in Data Centers Although more and more data centers have become more conscious of sustainability over the past decade, data centers remain one of the world's largest consumers of electricity as data demand is growing exponentially. According to the EU JRC, the information and communication technology (ICT) sector, including data centers, generates 2% of global CO2 emissions. According to the Mandipiai (MDPI) journal, its share of CO2 emissions is expected to rise to 8 percent by 2030 if no further measures are taken. For data centers, the electricity used to operate equipment and cool facilities accounts for about 86% of the total data center energy consumption, with cooling alone accounting for 40%. According to Hong Kong IDC New Horizon Interconnection, under pressure from multiple sources including regulators, investors and consumers, the data center industry has taken action to study and adopt sustainable operating models in an attempt to limit its impact on climate change. Many data center companies, led by massive corporations such as Google, Microsoft and Amazon, have also made commitments to operate data centers with renewable or carbon-free energy by 2025 and plan to achieve climate neutrality by 2030. According to a recent study by Global Market Insights, the green data center market is expected to be valued at more than $175 billion (approximately RMB 1.2 trillion) by 2030. Data centers reflect the ratio of total data center energy consumption to IT load energy consumption through the energy efficiency index (PUE), and the closer the PUE value is to 1, the more efficient the energy use is. Data centers take up 3% of the world's electricity, how should the energy problem be solved? In order to bring data center PUE closer to 1 and move closer to sustainable data centers, whether building new data centers or converting old buildings into data centers, there may be PUE requirements for data centers around the world in recent years to design data centers from the perspective of energy saving and using renewable energy. Singapore, for example, has thus implemented a data center ban from 2019 and did not open its green data center pilot program until July this year, with new data centers required to meet sustainability regulations to keep PUE below 1.3. Data Center Sustainability Trends 1. Finding Alternative Alternatives to Diesel Fuel Data centers need to be equipped with backup diesel generators to deal with unexpected situations such as power outages. Today, many data center operators are trying to reduce their reliance on diesel and looking for greener alternatives. Many data centers today are exploring hydrogen-powered fuel cells as an alternative to backup generators. While current technology does not yet guarantee the reliability of hydrogen fuel cells as a complete replacement for diesel generators, it is still worthwhile to continue research and development of the technology because hydrogen fuel cells produce zero emissions and its only byproduct as a fuel is water. As many as 37 percent of data center managers are currently considering implementing this technology in the coming year. In September, Equinix partnered with the Centre for Energy Research and Technology (CERT) at the National University of Singapore's (NUS) School of Design and Engineering to test hydrogen fuel cell power for a local data center, and in December, Dutch data center company NorthC developed the Eindhoven data center in the Netherlands, a facility that will use natural gas or hydrogen as an alternative to traditional diesel power generation. The facility will use natural gas or hydrogen as an alternative to traditional diesel power generation. 2. Renewable Energy The use of renewable energy sources is not only beneficial to the sustainability of data centers, but can also help them overcome the challenges posed by the energy crisis, with solar and wind power being more commonly adopted in data centers. Some hyper-scale enterprises have also started to purchase renewable energy to power their data centers. In September, Digital Realty signed a 650 GWh wind-based renewable energy deal with a Spanish renewable energy company, and in November, Google signed power purchase agreements (PPAs) in Texas and Spain, acquiring 942 MW and 149 MW of solar energy, respectively, to power local data centers. In the same month, Microsoft signed an agreement in Canada to purchase 543 GWh of wind power per year. 3. More Efficient Airflow Management While data centers cool equipment through air-cooled systems, airflow management means maximizing cooling efficiency and energy savings by minimizing contact between the cold air used to cool the server room and the waste heat in the facility. Therefore, it is a higher requirement for data center design to enable the facility to better manage the heating, ventilation and air conditioning systems so that airflow management becomes a virtuous cycle. 4. Cooling technologies for high-density computing As applications such as artificial intelligence and cryptographic computing that require large amounts of high-density computing become more popular, this means that traditional cooling methods in data centers may no longer be efficient. According to Gartner, a global consulting firm, liquid cooling is 3,000 times more efficient than air cooling. According to marketsandmarkets' forecast for the data center liquid cooling market, the market has grown rapidly in recent years and is expected to grow at an even higher rate in the coming years, from $2.1 billion (about RMB 14.6 billion) in 2022 to $6.4 billion (about RMB 44.6 billion) in 2027, a compound annual growth rate of 24.8%. 5. Saving Data Center Energy Costs with AI Identifying energy waste through smart sensors and deploying software to manage energy consumption will be more effective than manually monitoring power and can minimize PUE. There are already cases of using AI to assist data centers in reducing energy consumption today. Google saved 40% of energy for its data center in 2016 through its AI DeepMind. 6. Waste heat utilization Data centers hosting more powerful and intensive computing means more heat will be emitted, and how to deal with this waste heat is a challenge for data centers to consider. In the current case of data center waste heat utilization, using the waste heat for district heating for the local area or using the heat for crop farming nearby is a good direction. For example, QTS recently chose to connect its Groningen data center in the Netherlands to a local heating project, providing 2.5MW of waste heat generated by the data center. In addition, there is also the Hokkaido Mizaka Data Center in Japan, which heats air and water with heat generated by servers in order to try to grow food such as mushrooms, Japanese mustard spinach, coffee beans, abalone and sea urchin. Overall, while data centers continue to have significant power consumption problems, it's easy to see that in recent years, major data center operators have been making efforts to meet their climate and carbon neutrality commitments by trying to operate in a more sustainable manner.

At the same time, change also means opportunity, and IDC companies need to dynamically adapt to the external environment and policies to begin with the end in mind and seek a path to long-term stable development. For the coming 22 years, the IDC industry is mainly adapting to changes and constantly adjusting its own strategy for the year, and needs to continuously create value for customers with its own advantages and continuous innovation. In 2022, the digital economy will become the main line of global economic development. As the infrastructure of the digital economy, data centers play a fundamental role in supporting the take-off of the digital economy, and with the further development of the digital economy, the growth of data center demand is bound to be driven. However, while growing, we also need to pay attention to our national guidance on the healthy development of the data center industry. 2022, green, low-carbon and energy-saving will become the most core keywords for the sustainable development of data centers. 2.Data centers will develop rapidly and comprehensively, and continue to change and innovate Looking back to 2021, driven by both policy and demand, the industrial scale of China's IDC has approached 100 billion, the market investment scale has rapidly increased, and China's data center has officially stepped into the era of traffic enhancement. meta-universe is also exceptionally hot in 2021, and major central enterprises, unicorns and head Internet enterprises have entered meta-universe, and the importance of data assets and data center has been significantly increased again. Then, 2022 will be a year when the digital economy is riding high and the IDC industry will develop rapidly. In 2022, the whole data center industry will move from resource-driven to innovation-driven, and the data center market will enter the value competition stage. Medium and high density cabinets, elastic architecture, low carbon and energy saving, rapid deployment, AI intelligent operation and maintenance, security and trustworthiness will also be the main trends in the evolution of data center technology.

    Introduction to liquid cooling system 2
    November 17, 2022

    Characteristics of liquid cooling method 3.1 Make full use of the natural cooling source, energy-saving effect is obvious Liquid-cooled cabinet can make full use of the outdoor cooling source. Liquid-cooled cabinets in addition to cold plate liquid cooling, general spray and submerged liquid cooling of the server side in and out of the coolant temperature of 40 ℃ ~ 45 ℃, while the ambient temperature of the outside of the room can generally meet the requirements of the coolant cooling, spray and submerged liquid cooling can all use outdoor cold sources for server cooling, the overall PUE effect to improve significantly, and can make full use of natural cold sources, energy-saving effect is extremely The overall PUE is significantly improved, and natural cooling sources can be fully utilized, resulting in significant energy savings. The PUE of all three liquid cooling methods can reach below 1.2, especially the spray and submerged liquid cooling system is more obvious, saving about 20% of air conditioning power compared to air cooling, plus the elimination of the internal fan of the server, the IT part of the power can save 13% to 25%, the overall energy saving effect is more than 40%. For the current carbon emission, submerged and sprayed liquid cooling has a high temperature on its output water side, which has the value of waste heat recovery and utilization. If combined with partial waste heat utilization, the energy saving effect will have a significant space for improvement, and also can reduce the carbon emission intensity of the overall data center. 3.2 Low noise can be achieved in the server room The noise in the server room mainly comes from the server fans. According to the current national regulations, the noise value measured at the main operator position in the manned mainframe room and auxiliary area should be less than 65dB(A) when the electronic information equipment is down. As large data centers continue to emerge, it is becoming common for data centers with host rooms containing hundreds of network devices in size. When these devices are working at the same time, most of the noise is close to or exceeds 65dB, which is the noise value tested under normal operation and 50% to 60% load of the equipment, and can only be higher if working at full speed with adjustable fan speed. When the environmental noise exceeds 80dB, personnel have been unable to work in the environment for a long time, and the laws of Europe and the United States also provide that if the noise in the workplace reaches 80dB to 85dB, the corresponding occupational protection must be provided. Even if the cold plate type liquid cooling is used, the general fan works at a lower speed and the noise is lower than the conventional air-cooled form, so the noise value is greatly improved. In addition, due to its own characteristics, the liquid cooling system reduces the part of conventional cold sources (such as chillers, air conditioning outdoor units, etc.), which can also largely reduce the noise impact on the environment, and is relatively easy and friendly for the arrangement of the data center and the surrounding environment. 3.3 Small footprint Due to the simple structure of liquid cooling system, it can make full use of natural cooling source and reduce the layout of conventional data center's cooling source and ancillary equipment and pipeline, the system is simple and occupies a small area, plus the general liquid cooling cabinet can achieve high power density, which can realize 10~50kW power, saving a larger area than conventional. 3.4 Flexible system layout transformation Due to the small footprint of liquid cooling system, the simplicity of the system, the advantage of using natural cooling source, and the possibility of achieving high power density, the convenience can be greatly improved for the transformation or expansion of the data center. 3.5 Low environmental requirements for server rooms For submerged and cold plate type liquid cooling system server room, there is no positive pressure requirement for the server room, and there is no additional requirement for the neatness of the server room, and the requirement for the decoration of the server room such as wall and floor is low. Moreover, as the environment of the server room is mainly to meet the needs of personnel maintenance. The number of precision air conditioners and the arrangement of air conditioning rooms are reduced, and conventional air-cooled ends can be used, and the overall reliability of the server room's cold source needs are reduced. 3.6 Server reliability is improved and life span is extended 3.6.1 Low chip operating temperature and reduced energy consumption Since the conversion efficiency of liquid energy efficiency far exceeds that of air, and the liquid cooling system can directly dissipate heat to the chips and other key components of the server, the heat dissipation is precise and efficient, so the operating temperature of the key components of the server is significantly lower than the conventional air cooling heat dissipation temperature, and the temperature is constant, and the system can continue to run at high load, doubling the efficiency; and since the spray liquid cooling and submerged liquid cooling remove the server system fan, they can directly The energy consumption of the server is reduced by about 15% to 25%, while the cold plate type is reduced by about 5% to 10%. 3.6.2 Improved server lifetime The increase of server life is mainly reflected in two aspects. ① As the chip works mainly at a lower temperature and at a constant temperature, when reducing the vibration of the fan work (spray and submerged liquid cooling), it can significantly improve the life of the chip. ②Since the spray and submerged liquid-cooled server room is submerged in the coolant, the server does not need to be in contact with the air in the room, avoiding the accumulation of airborne dust and other particles in the server that can cause equipment failure. In addition, it also directly reduces the corrosion of the servers by moisture and dust in the environment, which improves the reliability and extends the service life of the equipment. 3.7 Low equipment maintenance expenses Compared with the spray and submerged liquid cooling, cold plate type liquid cooling system operation and maintenance costs are high, even more than the air-cooled system, mainly because of its use of pure water equipment operation and maintenance expenses are relatively high, and with the use of years of growth in costs almost doubled. Spray and submerged liquid cooling system has a simple structure, the number of components of the equipment is small, such as the number of equipment that eliminates the refrigeration host, air-cooled air conditioning, the probability of equipment failure will be reduced. In terms of the whole life cycle of the equipment, on the one hand, it reduces the spare parts of the equipment, and on the other hand, it can also reduce the manpower expenditure of the maintenance part at a later stage. The cold plate type is an additional set of liquid cooling pipes compared to the air-cooled system, and the system is more complicated. However, the coolant of partial immersion liquid cooling system uses fluorinated liquid phase change method, which requires overall shutdown for maintenance, and there is difficulty in maintenance, and the filling volume of liquid cooling coolant is the largest. From the three forms, the spray liquid cooling system, in addition to having a simple system, can do online maintenance, maintenance costs in the three for the lowest, overall in the later equipment life-cycle management, the overall maintenance costs of expenditure is the simplest, is the best one of the three ways. 3.8 Large upfront investment in equipment As liquid-cooled equipment is still in its infancy, the current liquid-cooled form is extremely small compared to traditional air-cooled rooms, coupled with some key materials such as coolant and other temporary monopoly by some companies, compared to conventional rooms, the initial investment in equipment is larger, and because some of the equipment needs to be customized, such as servers, when the required number of small cases, the cost is higher, the general initial investment for the traditional room 3 times More than. When the single cabinet management equipment density in more than 20kW and more than 500 cabinets, the cost will have a greater reduction. 3.9 Customer acceptance needs to be improved Liquid-cooled cabinets belong to a newer way, at present, customer acceptance is not as good as the acceptance of conventional air-cooled cabinets; because of the current investment in liquid-cooled rooms and the power density of the cabinets is greater, but with reference to the current social molding cases, the general power of liquid-cooled cabinets in 10 to 20kW or more, it is difficult to reach customer acceptance, the current basic use or transformation for own users, I believe that later with the liquid-cooled It is believed that with the promotion of liquid-cooled cabinets, the acceptance level of customers will be improved. Conclusion In summary, the advantages of spray liquid cooling compared with the other two liquid cooling methods are mainly reflected in the low weight of the server room, less coolant filling, simple system and low noise in the server room. Combined with the current characteristics of data scaling, there is a large utilization space in the application of server room renovation, upgrade of enterprise self-use server rooms, BBU small units in the communication industry, and there is a huge energy-saving potential in the use of natural energy, which is a new data center cooling method worth recommending.
