To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments, based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in figure 1, the embodiments of the invention provide a kind of method of testing of server fan function, can include following
Step：
Step 101：For at least one fan-slot set in server, each fan-slot correspondence is detected respectively
At least one rotation speed of the fan.
Step 102：Judge at least one corresponding rotation speed of the fan of each fan-slot, if there is any fan and turn

Step 104：For each fan-slot, judge the effective rotor number of institute's installation fan in the fan-slot, be
It is no to be not less than the corresponding preset value of the fan-slot, if being, determine to be mounted on correspondence fan in each fan-slot, it is no
Then, abnormality processing is carried out.
The embodiments of the invention provide a kind of method of testing of server fan function, set respectively in detection service device
At least one corresponding rotation speed of the fan of each fan-slot；Judging at least one corresponding rotation speed of the fan of each fan-slot
In, when there is any rotation speed of the fan more than fan minimum speed, determine to be mounted on fan in each fan-slot；Determine each wind
Fan at least one corresponding rotation speed of the fan of slot, the number more than fan minimum speed is institute's installation fan in each fan-slot
Effective rotor number；The rotor bank of institute's installation fan is corresponding pre- not less than the fan-slot in each fan-slot is judged
If during value, determining to be mounted on correspondence fan in each fan-slot.Due to can be it is determined that on fan basis in place, entering one
Step determines correspondence fan whether is provided with fan-slot, so as to provide corresponding radiating effect.Therefore, the present invention is implemented
Example being capable of accurate test server fan functionality.
Specifically, can be provided with server in multiple fan-slots, and each fan-slot can be provided with one
Individual fan, wherein, the rotor bank of institute's installation fan can be different, to provide different radiating effects.
In detail, be the equal of that 1 fan is rotated at the same time, therefore can detect if including 1 rotor in a certain fan
To 1 rotation speed of the fan.Similarly, be the equal of that 2 fans are rotated at the same time if including 2 rotors in a certain fan, therefore can be with
Detect 2 rotation speeds of the fan.But, if during one of rotor fault, the corresponding fan of the failure rotor may be can't detect
Rotating speed, or the value of the rotation speed of the fan detected are relatively low.
Under normal circumstances, when fan propeller number is different, the radiating effect that fan is provided is different.For example, in present invention implementation
In example, 2 rotation speeds of the fan of the birotor fan detected can with equal, and with the rotation speed of the fan of the single rotor fan detected
It is equal, but the air quantity of birotor fan can be 2 times of single rotor fan in theory, so that in theory it is believed that double turn
The heat-sinking capability of sub- fan can be 2 times of single rotor fan.
In a step 102, can be by each rotation speed of the fan detected and the contrast of fan minimum speed, to determine each wind
Whether fan is mounted in fan slot.
For example, if the corresponding rotation speed of the fan of a certain fan-slot illustrates the wind no more than fan minimum speed
The equal failure of rotor of institute's installation fan in slot is fanned, therefore abnormality processing can be carried out, such as warning reminding, output fan groove position information
And the rotation speed of the fan detected etc..
In addition, in an embodiment of the invention, if being not detected by the corresponding rotation speed of the fan of a certain fan-slot, illustrating
Fan is not installed in the fan-slot, therefore can equally carry out above-mentioned abnormality processing；If the corresponding multiple wind of a certain fan-slot
Fan in rotating speed, while there is a situation where to be more than fan minimum speed and no more than fan minimum speed, then illustrate the fan-slot
There is failure rotor in middle installed fan, but can continue executing with subsequent step.
In detail, the fan minimum speed pre-set can be 0rpm, or a suitable tachometer value, such as
10rpm。
In order to ensure to be mounted on correspondence fan in each fan-slot, fan is mounted in each fan-slot is confirmed
Basis on, can reaffirm whether installed fan can provide expected radiating effect.Wherein, in fan-slot
The following two kinds implementation can be had by being provided with correspondence fan：
Mode 1：The effective rotor number of institute's installation fan in fan-slot, preset value corresponding not less than the fan-slot；
Mode 2：The effective rotor number of institute's installation fan in fan-slot, preset value corresponding equal to the fan-slot, and
The failure rotor number of institute's installation fan is 0 in fan-slot.
In detail, for aforesaid way 1：
When the effective rotor number of institute's installation fan in fan-slot is not less than corresponding preset value, you can think the fan
There is corresponding fan in slot, therefore the correspondence fan can be：It is equal to expected radiating effect in the absence of failure rotor and radiating effect
Fan, there is failure rotor but actual radiating effect and be not less than the fan of expected radiating effect, in the absence of failure rotor but dissipate
Thermal effect is not less than any one in the fan of expected radiating effect.
For example, it is desired to which in installing the fan-slot of single rotor fan, single rotor fan can be installed, there is a failure and turn
The birotor fan of son, any one in birotor fan.By installing any fan, expected radiating effect can be reached
Really.It can be seen that, this implementation can make full use of to all types of fans, and be particularly suitable for use in fan kind and quantity deposit
Vacant situation.
In detail, the implementation process of this implementation can be if above-mentioned step 101 is to shown in step 104.
In detail, for aforesaid way 2：
In an embodiment of the invention, this method may further include：For each fan-slot, the wind is determined
Fan at least one corresponding rotation speed of the fan of slot, the number of no more than described fan minimum speed is is pacified in the fan-slot
Fill the failure rotor number of fan；
The effective rotor number for judging institute's installation fan in the fan-slot, if corresponding not less than the fan-slot
Preset value, including：Judge whether the effective rotor number of institute's installation fan in the fan-slot is corresponding pre- equal to the fan-slot
If value, and whether the failure rotor number of institute's installation fan is not 0 in the fan-slot.
As shown in the above, the corresponding fan installed in fan-slot can be in the absence of failure rotor and radiating effect
Equal to the fan of expected radiating effect.For example, it is desired to which in installing the fan-slot of single rotor fan, single rotor wind can be installed
Fan, to reach expected radiating effect, but does not generally install birotor fan or there is the birotor fan of a failure rotor.
It can be seen that, this implementation can be avoided using the fan that there is failure rotor, and can reduce the wave of fan cooling effect
Take.
In detail, it is predetermined to guarantee to provide after correspondence fan is mounted in determining each fan-slot
Radiating effect, can also further consider whether the rotating property of institute's installation fan is normal.
Therefore in one embodiment of the invention, in order to verify whether the rotating property of each fan is normal, to guarantee
Predetermined radiating effect is enough provided, so, this method can also include：At least one fan duty is set；
It is mounted on after correspondence fan, further comprises in described each fan-slot of determination：Fan is run
Pattern is set as manual mode；It is performed both by for each fan duty of setting：According to current fan duty, it is separately operable
The fan installed in each fan-slot, and read current at least one fan rotating property value；According to what is read
Each each current fan rotating property value, judges the whether normal operation of institute's installation fan in its corresponding fan-slot,
If so, the fan operational mode is set as into automatic mode.
In detail, staff can set at least one fan duty according to self-demand, for example, 3 can be set
Fan duty, respectively 100%, 50%, 30%.
In detail, at least one fan rotating property value, can there is following three kinds of implementations：
Mode A：Rotation speed of the fan；
Mode B：Fan rotates level of noise；
Mode C：Rotation speed of the fan and fan rotate level of noise.
In detail, for aforesaid way A：
In one embodiment of the invention, at least one fan rotating property value includes：Rotation speed of the fan；
Each each current fan rotating property value that the basis is read, judges institute in its corresponding fan-slot
The whether normal operation of fan is installed, including：Judge whether each current rotation speed of the fan read is satisfied by following formula
(1)；
Wherein, kvAllow sliding scales, V for rotating speedixFor current rotation speed of the fan, VimIt is corresponding for current rotation speed of the fan
The maximum rotation speed of the fan of institute's installation fan, Y in fan-slotiFor current fan duty.
For in theory, for any fan, when fan duty changes, rotation speed of the fan occurs correspondence and changed.Therefore, for
Institute's installation fan in any fan-slot, may be required in each when under forefan duty, the fan detected is corresponding
The equal coincidence formula of each rotation speed of the fan (1).
As an example it is assumed that current duty is 50%, single rotor fan is installed in the fan-slot currently detected, examined
The current rotation speed of the fan of the single rotor fan that measures is 5050rpm, and the maximum rotation speed of the fan of single rotor fan is
10000rpm, rotating speed allows sliding scales to be 5%, is computed understanding,Therefore
Judgement passes through.
Similarly, can be to judging when other all rotation speeds of the fan under forefan duty, and to other fans
Each rotation speed of the fan under duty judged, if judging to pass through, illustrates that the rotating property of each fan is normal, therefore can be with
Fan operational mode is set as automatic mode, so that server is normally run, and using each fan to server running
The heat of middle generation is effectively radiated.
In an embodiment of the invention, for aforesaid way 1, institute's installation fan in the fan-slot currently detected
, can be without the judgement to the corresponding rotation speed of the fan of failure rotor to exist during many rotor fans of failure rotor.
In detail, for aforesaid way B：
In one embodiment of the invention, at least one fan rotating property value includes：Fan rotates level of noise；
Each each current fan rotating property value that the basis is read, judges institute in its corresponding fan-slot
The whether normal operation of fan is installed, including：Judge whether each current fan rotation level of noise read is satisfied by following
Formula (2)；
Wherein, kNAllow sliding scales, N for noiseixLevel of noise, N are rotated for current fanimRotated for current fan
The maximum fan of institute's installation fan rotates level of noise, Y in the corresponding fan-slot of level of noiseiFor current fan duty.
For in theory, for any fan, when fan duty changes, rotation speed of the fan occurs correspondence and changed, and fan turns
Correspondence change can equally occur for dynamic level of noise.Therefore, for institute's installation fan in any fan-slot, it may be required in each
Individual to work as under forefan duty, each the corresponding fan of the fan detected rotates the equal coincidence formula of level of noise (2).
In detail, for aforesaid way C：
In one embodiment of the invention, at least one fan rotating property value includes：Rotation speed of the fan and fan
Rotate level of noise；
Each each current fan rotating property value that the basis is read, judges institute in its corresponding fan-slot
The whether normal operation of fan is installed, including：Judge whether each current rotation speed of the fan read is satisfied by above-mentioned formula
, and each current fan for reading rotates whether level of noise is satisfied by above-mentioned formula (2) (1).
As shown in the above, for any fan, when fan duty changes, rotation speed of the fan and fan rotation level of noise are equal
Can occur correspondence change.Therefore, for institute's installation fan in any fan-slot, it may be required in each and work as forefan
The corresponding equal coincidence formula of each rotation speed of the fan (1) of the fan detected under duty and each fan rotation level of noise
Equal coincidence formula (2).
In summary, by testing server fan function, it is ensured that in server in each fan-slot
Correspondence fan is installed, and the rotating property of each fan is normally errorless, this implementation can be avoided in server quantity of heat production
Greatly, in the case of environment temperature is higher etc., thus server fan heat sinking function it is not enough caused by server delay machine phenomenon so that
Client can be avoided to lose, improve manufacturer server goodwill.
As shown in Fig. 2 one embodiment of the invention provides the method for testing of another server fan function, this method
Based on aforesaid way 2 and mode C, specifically it may comprise steps of：
Step 201：For 4 fan-slots set in server, detect that each fan-slot is corresponding extremely respectively
A few rotation speed of the fan.
For example, 4 fan-slots, respectively slot 1, slot 2, slot 3, slot 4 are provided with server.According to
Need to install successively in actual radiating requirements, 4 fan-slots：Birotor fan, single rotor fan, single rotor wind
Fan, birotor fan.
Assuming that staff installed successively in 4 fan-slots be：The single rotor of birotor fan, rotor fault
Fan, birotor fan (belong to install), the birotor fan of rotor fault by mistake.After server fan assembling is completed,
Server fan functional test can be carried out.Therefore, at least one the corresponding rotation speed of the fan of 4 fan-slots detected can
To be followed successively by：V and v, 0, v and v, 0 and v.Wherein, v ＞ 10rpm, such as can be 5000rpm.
Step 202：Judge at least one corresponding rotation speed of the fan of each fan-slot, if there is any fan and turn
Speed is more than the fan minimum speed pre-set, if being, determines to be mounted on fan in each fan-slot, otherwise, enters
Row abnormality processing simultaneously terminates current process.
In detail, the fan minimum speed pre-set can be 0rpm, or a suitable tachometer value, such as
10rpm。
In detail, because at least one corresponding rotation speed of the fan of 4 fan-slots is followed successively by：V and v, 0, v and v, 0 and
V, therefore slot 2 is not present any rotation speed of the fan and is more than fan minimum speed, therefore abnormality processing, such as warning reminding can be carried out,
The identification information of slot 2, the output corresponding rotation speed of the fan of slot 2 etc. are exported, and terminates current process.
Therefore, staff can install fan for slot 2 and be changed, and perform after replacing step again
201.Assuming that the fan after changing is single rotor fan, and the rotating speed detected is inserted for v, i.e. 4 fans of this currently detected
At least one corresponding rotation speed of the fan of groove is followed successively by：V and v, v, v and v, 0 and v, therefore subsequent step can be continued executing with.
In an embodiment of the invention, the speed of inspection fan can be gone by IPMI orders, and is turned with fan minimum
Speed is contrasted, and this realizes that code can be with as follows：
Step 203：For each fan-slot, determine at least one corresponding rotation speed of the fan of the fan-slot, greatly
The effective rotor number of institute's installation fan in the number of fan minimum speed is the fan-slot, no more than fan minimum speed
Number for institute's installation fan in the fan-slot failure rotor number.
From the above mentioned, it may be determined that the effective rotor number of institute's installation fan is followed successively by 4 fan-slots：2nd, 1,2,1,
Failure rotor number is followed successively by：0、0、0、1.
In an embodiment of the invention, it is assumed that the rotor bank of fan is 1 or 2, can also compare the fan detected
Rotating speed number and fan physics number, if both numbers are equal, it is a rotor to mean that fan, if rotation speed of the fan
Number is precisely twice of fan physics number, and it is two rotors to mean that fan.Wherein, due to current in a fan-slot
One fan can be only installed, therefore fan physics number is 1.This realizes that code can be with as follows：
Step 204：For each fan-slot, judge institute's installation fan in the fan-slot effective rotor number whether
Preset value corresponding equal to the fan-slot, and whether the failure rotor number of institute's installation fan is 0 in the fan-slot, if
It is to determine to be mounted on correspondence fan in each fan-slot, otherwise, carries out abnormality processing and terminate current process.
As shown in the above, the corresponding preset value of 4 fan-slots can be pre-set and be followed successively by 2,1,1,2.
By the effective rotor number of institute's installation fan in 4 fan-slots is followed successively by：2nd, 1,2,1, failure rotor number according to
It is secondary to be：0、0、0、1.Through judging to understand, slot 3 and the corresponding effective rotor number of slot 4 are not equal to corresponding preset value, and insert
The corresponding failure rotor number of groove 4 is not 0, therefore can carry out abnormality processing, such as warning reminding, and exports the groove of slot 3 and slot 4
