/ Daily News/July 05, 2022 Guangzhou -- As a basic principle of fintech development, according to the Implementation Plan of implementing the target of carbon peaking and carbon neutrality and promoting the green and high-quality development of new infrastructure such as data centers and 5G, The average power utilization efficiency of newly built large and ultra-large data centers will be raised to below 1.3, and national hub nodes will be further raised to below 1.25. As one of the important components of data center energy consumption, servers with higher energy efficiency can not only effectively reduce energy consumption, but also better help to achieve the goal of carbon peak carbon neutrality.
Inspur K1 Power's unique workload dynamic optimization frequency energy-saving mode can better support the construction of green and low-carbon data center.
Inspur K1 Power server uses EnergyScale technology to realize multiple power management modes for servers, including a new variable processor frequency mode that can provide significant performance improvements beyond the static nominal frequency. Specific energy saving modes are as follows:
Disable all modes: Disable power saving mode. The processor clock frequency is set to a nominal value, and the power used by the system remains at a nominal level.
Enable static mode: Reduces power consumption by reducing the processor clock frequency and voltage to a fixed value. This option also reduces the power consumption of the system while still providing predictable performance.
Enable Dynamic performance mode: enables processor frequency to vary according to processor usage. During medium or high frequency usage, the processor frequency is set to the maximum allowable value, which may be higher than the nominal frequency.
Enable Maximum performance mode: Sets the processor frequency to a fixed value that can be specified. You can set maximum limits on the system processor frequency and power consumption.
The following two figures show the CPU frequency range of Inspur K1 Power server in different energy saving modes, and the influence of different modes of the current mainstream POWER9 server on CPU performance output and energy consumption:
At the same time, PowerVM hardware virtualization can further help save energy. As shown in the following figure, after PowerVM virtualization consolidation, server utilization increased to 70% and power consumption decreased from 8KW to 4KW.
In addition, with the improvement of the core computing power of the host, the configuration required for the same workload is lower and the carbon emission is lower, as shown below:
China 2021 CO₂ emission coefficient =0.997kg CO₂ / KWh
Calculate that the Power10 server saves 5KW than the POWER8 server.
Reduce CO₂ emission = 0.997 * 5 * 24 * 365 = 43.7t
Reduce C emission = 0.272 * 5 * 24 * 365 = 11.9t
Reduce standard coal use = 0.4 * 5 * 24 * 365 = 17.52t
Based on the calculation of 7.1 tons of carbon dioxide emissions per capita in China in 2019, save the total annual carbon dioxide emissions of 6 natural persons
