Problems solved by technology

[0003] In order to verify the function of fan redundancy, in the prior art, the fan redundancy test of BMC is basically manual plugging and unplugging of the fan, which needs to be opened, which is relatively dangerous
Moreover, the existing test needs to plug and unplug the fan, which cannot achieve long-term switching verification

Embodiment 1

[0028] The first embodiment of the present invention proposes a method of server fan redundancy test. First, the initial speed of the server fan is acquired, when any set of fan speed is zero, by comparing the remaining to determine the rest of the fans by comparing the initial speed The current speed fluctuation exceeds the fluctuation threshold; if the threshold is not exceeded, it is determined whether the actual speed of the fan is maximized if the actual speed of the fan is tested.

[0029] Such as figure 1 A method flow diagram of a server fan redundancy test is given in the first embodiment of the present invention.

[0030] In step S1O1, the initial speed of the server fan to be tested is obtained. In the present invention, the BMC first acquires the initial speed of the server fan to be measured.

[0031] In step S102, the rotational speed of any set of fans is set to zero. BMC controls the fan speed through the CPLD, and the CPLD can turn off the channel of the BMC to c...

Embodiment 2

[0044]Based on a method of server fan redundancy test proposed by the present invention, the present invention also proposes a system of a server fan redundancy test. Such as image 3 A system diagram of a server fan redundancy test is given in Example 2 of the present invention.

[0045] The system includes a substrate management controller, an editable logic chip, and a server fan to be tested.

[0046] The substrate management controller is used to obtain the initial speed of the acquired server fan, and the issuance command to the editable logic chip, allows the editable logic chip to turn off any fan channel to make the speed of zero, get the current speed fluctuation of the rest of the fans to be tested, and It is determined whether the current speed exceeds the fluctuation threshold; if the volatile threshold is not exceeded, the CPU pressurizing tool is controlled to pressurize, and if it is determined in the case of CPU pressurization, the actual speed of the fan to be tes...

Abstract

The invention provides a server fan redundancy test method and system. The method comprises the steps of acquiring the initial rotating speeds of to-be-tested server fans; setting the rotating speed of any fan as zero, acquiring the current rotating speeds of the other fans to be tested after waiting for the first period of time, comparing the current rotating speeds of the other fans to be testedwith the initial rotating speed, and judging whether the current rotating speed fluctuation of the other fans to be tested exceeds a fluctuation threshold value or not; if not, running a CPU pressuretool, acquiring the actual rotating speeds of the other fans to be tested after the second period of time, and judging whether the actual rotating speeds of the other fans to be tested reach the maximum value or not. Based on the method, the invention further provides a server fan redundancy test system. According to the server fan redundancy test method and system, the logic of a CPLD is modified, the signal channel between a BMC and the fans is cut off, physical isolation between the BMC and the fan is achieved, fan redundancy function testing can be implemented without plugging the fans inor unplugging the fans or with fan breakdowns, and stability of a whole machine heat dissipation strategy can be achieved.

Description

Technical field [0001] The present invention belongs to the field of server fan performance testing, and in particular, the present invention relates to a method and system of a server fan redundant test. Background technique [0002] With the continuous development of server technology, the server is constantly moving towards the direction of modularization, and the reliability and convenience of server operation and maintenance is also increasing. In servers based on domestic platforms, in order to ensure the heat dissipation performance of the whole machine, the fan has made redundant settings, preventing a fan failure, the whole machine heatspring is affected, and the general heat dissipation design is in accordance with 3 + 1 mode. That is to: the server has a total of 4 sets of fans, where one of the groups fails, and the other three groups can also provide normal heat dissipation. [0003] In order to verify the function of the fan, the fan redundancy test of BMC in the pr...
