Inspur Information G7 Server Cooling Solution
Under the dual carbon strategy, enterprises are increasingly valuing green investment. Many companies attach great importance to investing in green construction of data centers, but often overlook the green design of servers themselves. As one of the three major infrastructure of a computing power center, servers are the core element of building a computing power center, and the overall power consumption can account for 40% -50% of the total energy consumption.
Inspur Information G7 server, relying on years of experience accumulated in infrastructure and solution development, innovates the "seven green black technologies", solves server heat dissipation problems through multiple hardware and software optimizations, achieves comprehensive green upgrades of servers, and improves overall heat dissipation capacity by more than 24%. A single device can save nearly a thousand kilowatt hours of electricity per year, and the PUE can be reduced to below 1.1, Assist users in running various application loads in a green and efficient manner, promoting the sustainable development of modern data centers.
Research has shown that for every 1 ° C increase in ambient temperature, data centers can save 4% of cooling energy consumption, while increasing ambient temperature poses new requirements for server cooling. In terms of hardware, the fan in traditional air-cooled servers serves as the power source for internal heat dissipation, which is the first step in optimizing G7 server components. At different speeds, different blade angles of attack will generate different airflow fields. The G7 server's products have undergone tens of thousands of simulation experiments to find the optimal blade angle of attack through precise calculation of blade spacing and shape, increase air volume and reduce vibration. At the same time, the motor efficiency, internal structure, and material are optimized to maximize the airflow per unit energy consumption and achieve a 15% reduction in energy consumption.
For the high-power components, the G7 server tested hundreds of different forms and materials of heat sinks, and ultimately defined various solutions such as standard cooling , T-shaped heat dissipation, siphon heat dissipation, and cold plate heat dissipation according to different products and configurations. Among them, by using the effective space of the server to increase the windward surface of the heat sink fins, it can solve the air-cooled heat dissipation needs of 500W CPUs; By utilizing a uniform temperature plate and a heat sink capillary structure, the chip's heat is dissipated in a three-dimensional direction, which can meet the cooling requirements of up to 700W GPU.
Facing users with higher demand for reducing PUE values, Inspur Information G7 servers support innovative technologies such as cold plate liquid cooling and immersion liquid cooling. Cold plate liquid cooling covers high power components such as CPU and memory, with liquid cooling covering more than 70% of the power consumption. At the same time, the liquid cooling module also accommodates multiple mainstream liquid cooling quick connect solutions, effectively reducing overall energy consumption and deployment costs, which can help data centers reduce PUE to below 1.1.
For the optimization of overall cooling strategy, the G7 server has more than 400 sensors built-in in each product to timely collect temperature information at different positions such as air intakes. By combining the detected information with unique intelligent control technology for overall machine zoning, the fan speed can be intelligently adjusted according to the power consumption of components in different air ducts, solving the problem of temperature transmission lag, achieving energy-saving speed regulation and precise air supply for fans, Efficiently supporting the green and low-carbon development of data centers.
