Abstract

The invention provides a BMC chip, an Expander chip and a cooling method and system of a server. The cooling method of the server comprises the steps that a two-dimensional array is built according to the preset number of PWM fan variable speed curves and the preset number of PWM cooling fans; then based on obtained current temperature values of preset temperature acquisition location points and preset corresponding congruent relationships, and PWM parameter values corresponding to the obtained temperature values are calculated in real time and correspondingly written in the two-dimensional array; afterwards, effective values of the PWM parameter values currently corresponding to the PWM cooling fans are traversed, actual regulation PWM parameter values currently corresponding to the PWM cooling fans are further calculated, and then rotational speeds of the cooling fans are correspondingly regulated. The cooling method is separately integrated into the BMC chip, the Expander chip and the cooling system of the server. The applicability to different server platforms is improved, and the universality of the cooling system of the server is improved.

Description

technical field [0001] The invention relates to the field of heat dissipation of servers (including storage), in particular to a heat dissipation method and system for BMC chips, Expander chips, and servers. Background technique [0002] With the development of science and technology and the continuous improvement of human life, in a limited space, the density of servers is constantly increasing, which generates more heat. The heat dissipation of the server is one of the key issues in the system engineering of the server (including storage). If the heat generated by the server cannot be dissipated in time, when the undissipated heat accumulates to the point where the temperature of the server reaches a certain level, the performance of the server will drop sharply. [0003] And there are many types of existing servers. In terms of the number of CPUs, server forms include 2-channel, 4-channel, 8-channel, and more than 8-channel. In terms of chassis height, servers include ...
