Huawei servers are the hottest energy-saving bench

Huawei server: be the benchmark of energy saving in data center

server is one of the three basic it components of IDC data center, and the power consumption accounts for about 40% - 50% of the total energy consumption of the data center. With the continuous expansion of the size of the data center, the power cost of the data center even exceeds the purchase cost of IT equipment. Therefore, reducing the power consumption of servers has become the top priority of data center energy conservation and reducing operating costs

Huawei servers implement the concept of green energy conservation throughout the product life cycle, adopt a variety of patented energy-saving technologies, and improve the energy efficiency ratio by 15% - 30%. In the energy efficiency test of spec standardization organization, Huawei fusionserver 2288h V3 ranks first in the field of CPU servers of the same model. To achieve this, intelligent monitoring of each component and fine management of the power consumption of the whole machine are indispensable

intelligent monitoring, dynamic energy saving

the dynamic energy saving technology of Huawei server includes: dynamic energy saving of DEM, component hibernation, power supply off, etc. The dynamic energy-saving technology represented by Huawei server demt can monitor the operation status of power supply, processor, fan and other components on the basis of intelligent monitoring system status, so as to achieve energy-saving effect. On the basis of meeting the business load, taking highly accurate measures to reduce power consumption is the core advantage of dynamic energy saving of Huawei servers. 5. Force measurement range: 50N, 100N, 200N, 500N, 1000N, 2000N, 5000n

DEM (dynamic energy management technology) is a dynamic energy-saving technology for Huawei servers. This technology automatically monitors the resource usage of the current server according to the business load pressure, dynamically adjusts the server operation status according to the resource utilization, provides power supply according to the business needs, and minimizes the server power consumption. The features of demt technology include:

greatly reduce the power consumption of the whole machine under various loads, but do not affect the business performance of users

automatic triggering and closed-loop monitoring, without manual intervention, realize the energy-saving design of intelligent server

adjust the power supply, processor, fan and other components of the server to achieve the lowest power consumption operation state that meets the business requirements

the energy-saving range of Huawei demt technology under different business loads is shown in the following figure. A single rack server can save 1357 kwh a year:

Huawei server component hibernation technology includes: CPU C-state hibernation, hard disk hibernation, power module hibernation and other component hibernation. When the processor is idle for a long time, it will trigger to enter c1/c3/c6/c7 and other sleep states. According to the setting of sleep state, the processor will cut off the internal clock of the CPU or reduce the CPU voltage to save energy. The power consumption of a single processor after deep sleep can be reduced by more than 50%

power supply phasing is another key dynamic energy-saving technology. The processor and memory of Huawei server adopt polyphase power supply. According to the business load, the processor controls the opening and closing of VRM polyphase power supply through SVID (serial voltage ID), which can improve the power supply conversion efficiency of server CPU and memory by 5~8%

energy saving of the whole machine, Zhizai management

the energy-saving technologies of the whole machine provided by Huawei server include: power capping, starting low power consumption, HVD driving precision hydraulic cylinder C power supply, energy-saving thermal design and other energy-saving technologies. Among them, power capping, high-voltage DC and other technologies are common energy-saving technologies in the industry, but there are great differences in technical accuracy, power supply efficiency and other aspects. Huawei pursues fast and accurate operation, adheres to the concept of efficient environmental protection and detailed design, and now Huawei servers have reached the industry-leading level in the fields of environmental protection, power efficiency, precision control and so on

Huawei servers provide industry-leading power capping technology, which can realize fast and accurate power capping operation, effectively improve the power supply efficiency of the computer room, improve the density of cabinet equipment, and reduce the maintenance cost of the computer room on the premise of ensuring the power supply safety of the computer room. At the same time, eliminate the risks of insufficient heat dissipation and power supply under abnormal conditions (such as air conditioning failure, sudden increase in business volume) and improve business reliability

Huawei's low-power technologies for server startup include: staggered peak power on of hard disk, staggered peak power on of blade, and CPU core off technology, which ensures that the power consumption of the server during power on is lower than the operating power consumption of the system, eliminates the power supply risk caused by excessive current at the moment of power on of hard disk and other components, and saves users' electricity charges at the same time

hvdc high-voltage DC power supply is the development trend of server power supply. By reducing the number of power conversion stages, the power supply efficiency can be improved. 2. Speed up the construction of the national power battery innovation center and additive manufacturing innovation center by 15%. At the same time, it can solve the large current problem caused by low-voltage DC power supply such as - 48V. In addition, Huawei server also provides a hybrid power supply scheme of HVDC and 220VAC, using HVDC as the main power supply and AC power supply as backup, which not only greatly improves the power supply efficiency, but also ensures the N + n redundancy of power supply and improves the reliability of products

Huawei server provides an intelligent energy-saving thermal design scheme, which collects real-time temperature and power consumption information through sensors all over the main components, cooperates with the ambient temperature and business load pressure, and realizes energy-saving speed regulation and accurate air supply of fans. The fan provides the appropriate cooling air volume according to the business load, and at the same time, it cooperates with the low wind resistance layout of the hardware to achieve the lowest power consumption and noise of the server, avoiding the use of a single temperature speed regulation algorithm, resulting in high power consumption, high noise, and high device temperature, which affects the business performance

with the increasing number of equipment in the data center, energy conservation and emission reduction is not only an important measure for society, but also an important measure to reduce operating costs, and a necessary guarantee to improve our ecological environment. Environmental protection, energy conservation and green low carbon are the design principles of Huawei servers. All Huawei servers meet the certification of energy star, national environmental protection certification, CQC energy conservation and other certification, and fully realize lead-free design and non-toxic substances. Huawei helps customers realize a green data center with high performance, low power consumption, high reliability and low cost through leading server energy conservation and emission reduction technology
