Abstract

The invention provides a fan control method based on the NUMA computer system structure. In computer systems using an FPGA device, such as physical layer multi-partition computers, an NIOS II soft core is established in the FPGA to monitor server system temperature and control and manage operation of a fan cooling system. A custom PWM module IP core is further provided. The functions such as temperature function, a PWM fan control module, a fan speed detection module, DDR2 SDRAM storage control and Flash storage control are integrated in the NIOS II soft core of the FPGA. Compared to the fan control method based on the NUMA computer system structure is flexible to use, well extensible, highly practical, and easy to popularize.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a fan control method based on NUMA computer architecture. Background technique [0002] The characteristic of NUMA's multi-physical layer partition computer architecture is that multiple processors and IO resources of the computer system can be divided on the physical layer, thereby dividing a multi-processor computer system into multiple independent multi-processor systems. , these divided computer systems can also be coupled into a complete computer system. The system often has a complex chassis structure, which requires multiple temperature detection points, multiple fan controllers, and multiple air ducts for heat dissipation. [0003] Ordinary NUMA processor architecture or single-processor system architecture servers usually use hardware monitoring IC series chips (such as W83795 series). This series of IC chips can detect the temperature of multiple points ...
