With the explosion of digital transformation and cloud computing technology and applications, data centers have shifted from traditional CPUs as the core to a stage where CPU, GPU, ASIC, FPGA, DPU and other hardware and chip architectures and diverse computing powers coexist. For enterprises, computing power is productivity in digital transformation, and the underlying computing power base may be the most important support and opportunity for enterprises to seek business innovation and commercial competition. Therefore, while data centers pursue more efficient and flexible computing power while taking into account green and low power consumption, it is also an important challenge for IT underlying technology manufacturers.
Inspur Computer, an important manufacturer in China's enterprise-level server market, is also an important enterprise in the computing power base ecological chain. Inspur Computer has accumulated many achievements in the design of multiple heterogeneous computing systems, the design of green energy-saving computing systems, and the design of stable and robust computing systems. Practical results. Recently, the person in charge of Inspur Computer’s technology and products was interviewed by the media and introduced in detail Inspur Computer’s experience and insights into multi-heterogeneous, green and low-carbon computing power bases and complete cabinet products.
Inspur computer basic technology research focuses on multi-heterogeneous, green and energy-saving, and system stability
Heterogeneous computing in data centers involves many aspects of R&D and design. For example, Inspur Computer has explored the design of technologies in the entire machine's multi-heterogeneous computing architecture, hybrid architecture balancing, signal integrity, heat dissipation design and firmware tuning. Specifically, in terms of high-density and high-speed interconnection technology, Inspur Computer carries out research on high-precision finite element 3D modeling and simulation technology, challenges the limits of high-speed signal design, and establishes high-speed interconnection design specifications that are higher than industry standards. PCBs with the same loss level Achieved higher signal transmission distance under board conditions; carried out research on high-density and high-speed PCB interconnection technology of more than 40 layers to achieve high-speed signal board-level transmission requirements of 56Gpbs and above under industrialized mass manufacturing conditions, and the wiring density is in the leading position in the world. level.
In addition to multi-element heterogeneous computing, there are also green and energy-saving computing system design capabilities. Inspur Computer's complete machine research and development uses dynamic voltage and frequency adjustment technology, intelligent energy efficiency management technology, and complete machine cooling strategy design to uniformly monitor the status of each chip in the server and dynamically adjust the chip working mode to achieve more optimization of the power consumption of the complete machine. Specifically, in terms of heat dissipation technology for high-power server systems, Inspur Computer uses new metal phase-change thermal conductive materials to achieve air-cooling heat dissipation for 8-card 500W GPUs in a 4U space. In addition, it has developed directional immersion cooling technology to achieve high-power performance of more than 700W. Directional immersion cooling of consumption chips will greatly improve system heat dissipation efficiency and reduce PUE. In addition, there are siphon heat dissipation, waveguide heat dissipation, etc. to improve the efficiency of traditional air-cooling design, and dynamic energy-saving management technology to adjust the number of power activations in real time to improve the power consumption efficiency of the entire machine.
Third, for stable and robust computing system design capabilities, Inspur Computer focuses on the complete machine system, researching the reliability design of the complete machine, manageable design, and easy-maintenance design technology to improve the reliability and stability of the complete machine. Specifically, in response to server system reliability design requirements, Inspur Computer established more than ten accelerated failure factor models covering component expansion coefficients, operating temperatures, etc., and verified the relationship between acceleration factor (Af) and life cycle (Nf). relation,. In addition, there are underlying threshold and funnel technologies, self-developed power consumption capping technology, innovative NVMe hot-swapping technology, as well as manageable designs such as development test fixtures, 400A-level power integrity technology, 32G high-speed bus simulation, and online upgrades and wireless Personnel on duty, real-time monitoring of hardware error reports, etc.
It is precisely because of the research and accumulation of these basic technologies in terms of multi-heterogeneity, green energy saving, and system stability that Inspur Computer can deliver complete cabinets in large-scale and ultra-large-scale data centers, and ultimately achieve low-cost, low-cost data centers. Rapid deployment and simplified operation and maintenance.
What other hard-core technologies are there for Inspur computers delivered as complete cabinets?
As digitalization accelerates, in addition to major Internet companies, customers in operators, finance and other industries are also increasing their demand for full-rack servers. In these user scenarios, there are usually general-purpose server clusters and multiple computing, storage, and network management platforms. Inspur Computer also sees that the current ecological development of data center servers is still diversified and no unified standards have been formed. Therefore, Inspur servers realize cabinet node decoupling, are compatible with common server models, and realize unified management across platforms and different storage network technologies, shielding heterogeneous differences and achieving seamless migration. In addition, the entire cabinet has centralized power supply. , Power pooling combined with dynamic energy-saving adjustment technology significantly reduces data center power consumption.
Specifically, first of all, current cabinet server products generally tend to be customized for large-scale customers. It is difficult to form a unified standard and cannot be compatible with general servers and their application scenarios. The coverage of customer applications in other industries is insufficient. Large-scale promotion brings great difficulties. Inspur Computer's innovative technology, the whole cabinet server, is the first to decouple cabinets from nodes and achieve compatibility with general server models. Customers can combine them as needed like building blocks according to business needs; realizing liquid cooling, centralized cooling, intelligent management, etc. The smooth expansion of value-added features, as well as the compatibility for integrated delivery and on-site value-added function expansion, will ultimately promote the large-scale promotion of full cabinet servers throughout the industry.
In addition, with the increase in user scenario applications, the requirements for computing power or computing characteristics in some specific scenarios are becoming more and more complex, leading more and more enterprises to choose multi-architecture computing power and Inspur Innovation Technology whole-rack servers. A unified interface standard has been established to manage these heterogeneous computing resources, achieving unified management of heterogeneous computing power and related storage and network resources, and enabling the application deployment of computing resources on different platforms and different technical routes. Resource scheduling, policy setting, and security management can monitor multiple indicators such as the operating status and usage of each computing unit in real time, and provide regular inspections, intelligent monitoring alarms, and automatic fault repairs to grasp and handle emergencies to help users Realize the seamless migration of computing power resources on different platforms and different technical routes, shield heterogeneous differences, improve resource utilization, and reduce operation and maintenance costs.
Finally, Inspur Computer Innovation Technology’s whole cabinet server adopts centralized power supply mode, supporting N+N or N+2 redundant 80Plus titanium power supply. The 48V output supplies power to the whole cabinet through Busbar, which can meet the power supply needs of multiple nodes and balance the load. Output; combined with dynamic PSU energy-saving adjustment technology, the power supply works at the 50% load efficiency point when the entire device is fully loaded; compared with the distributed power supply mode, the comprehensive energy consumption of Inspur's whole cabinet server is reduced by up to 4.6%. For data on the scale of 1,000 cabinets center, saving up to 2.5 million kilowatt hours of energy per year, reducing data center operating costs.
