Description

Technical Field

[0001] The present invention relates to computer technology, and in particular to a hard disk abnormality analysis method, device, electronic equipment and storage medium. Background Art

[0002] At present, the heat dissipation method of servers is mainly air cooling, and the storage device is mainly mechanical hard disk. The operation of the heat dissipation device will cause mechanical vibration. When the heat dissipation device is running at a high speed, the gap between the magnetic head and the disk in the mechanical structure of the mechanical hard disk is at the nanometer level, which is very susceptible to mechanical vibration, causing the hard disk to easily produce abnormalities such as read and write speed reduction. Therefore, it is necessary to improve the corresponding structure in the server to reduce the impact of the operation of the heat dissipation device on the hard disk.

[0003] In the prior art, it is impossible to directly determine the cause of the hard disk abnormality. Therefore, the corresponding structure is often randomly improved, and the hard disk operation status after the structure improvement is tested to determine whether the improvement is correct, which reduces the efficiency of solving the hard disk abnormality problem. Summary of the invention

[0004] The present invention provides a hard disk anomaly analysis method, device, electronic equipment and storage medium to improve the accuracy and efficiency of obtaining hard disk anomaly analysis results.

[0005] According to one aspect of the present invention, a hard disk abnormality analysis method is provided, the method comprising:

[0006] Determine a current excitation source from candidate excitation sources, determine a current target point from candidate target points, and determine a current transfer path from candidate transfer paths according to the current excitation source and the current target point; wherein the candidate excitation source is at least one heat sink of the target server, the candidate target point is at least one hard disk of the target server, and the candidate transfer path is a path formed by a set of connection devices between each heat sink and each hard disk;

[0007] In a preset non-working state, determining a current transfer function corresponding to the current transfer path by applying a target excitation to the current excitation source;

[0008] Under a preset working state, obtaining a total response of a first target point, and determining a first current response of the current target point to the current excitation source according to the current transfer function and the total response of the first target point;

[0009] A current path contribution of the current transfer path is determined according to the first current response, and a hard disk abnormality analysis result is determined according to the current path contribution.

[0010] Optionally, determining a current transfer function corresponding to the current transfer path by applying a target excitation to the current excitation source includes:

[0011] Obtaining a second current response of the current target point to the current excitation source by applying the target excitation to the current excitation source;

[0012] The current transfer function is determined based on the target stimulus and the second current response.

[0013] The advantage of this setting is that by applying the target excitation by the current excitation source in the preset non-working state, the second current response of the current target point to the current excitation source is obtained, and the current transfer function is determined according to the target excitation and the second current response, thereby decoupling the vibration response caused by the overall excitation source, obtaining the transfer function from a single current excitation source to a single current target point, and improving the accuracy of determining the current transfer function.

[0014] Optionally, determining a first current response of the current target point to the current excitation source according to the current transfer function and the first target point total response includes:

[0015] constructing a transfer function matrix according to the current transfer function;

[0016] Determining a total excitation of an excitation source according to an inverse matrix of the transfer function matrix and a total response of the first target point;

[0017] The total response of the second target point is determined according to the total excitation of the excitation source and the transfer function matrix, and the first current response is determined according to the total response of the second target point.

[0018] The advantage of this arrangement is that: a transfer function matrix is ​​constructed according to the current transfer function; the total excitation of the excitation source including the decoupled excitation source excitation under the working state is obtained by multiplying the inverse matrix of the transfer function matrix and the total response of the first target point; and the total response of the second target point is determined according to the total excitation of the excitation source and the transfer function matrix, and the total response of the second target point including the first current response is obtained, thereby determining the first current response, and solving the problem that the response caused by a single excitation source to a single target point cannot be obtained due to the excitation coupling of the excitation source under the working state.

[0019] Optionally, determining a hard disk abnormality analysis result according to the current path contribution includes:

[0020] Determining a path contribution degree of the current transfer path according to the current path contribution amount and the current target point response;

[0021] The hard disk abnormality analysis result is determined according to the path contribution degree.

[0022] The advantage of this setting is that by determining the path contribution of the current transmission path and determining the hard disk anomaly analysis result based on the path contribution, the impact of the transmission path on the hard disk anomaly is made more intuitive, which facilitates rapid positioning of the transmission path that causes the hard disk anomaly and improves the efficiency of hard disk anomaly analysis.

[0026] The advantage of this setting is that the current path contribution of the current transmission path is determined based on the first current response and the directional angle between the current target point response and the first current response, and the projection of the first current response on the total response direction of the first target point is used as the current path contribution, thereby achieving the response contribution of a single current excitation source to a single current target point, which is convenient for subsequent judgment of the excitation source and target point causing the hard disk abnormality based on the current path contribution, narrowing the judgment scope of the hard disk abnormality problem and improving the accuracy of hard disk abnormality analysis.

[0027] Optionally, also include:

[0028] In response to a hard disk abnormality analysis request, a target rotation speed of the current excitation source under the preset working state is determined.

[0029] The advantage of this setting is that by responding to the hard disk abnormality analysis request, the corresponding target rotation speed is determined, so as to avoid the situation where the rotation speed of the current excitation source corresponding to the preset working state is fixed, and different hard disk abnormalities caused by the current excitation source at different rotation speeds may not be discovered. For example, the current excitation source causes hard disk 1 abnormality at a high rotation speed and hard disk 2 abnormality at a low rotation speed, etc., which affects the comprehensiveness of the hard disk abnormality analysis, thereby improving the accuracy of the hard disk abnormality analysis.

[0030] Optionally, determining a current transfer path from candidate transfer paths according to the current excitation source and the current target point includes:

[0031] The current transfer path is determined from the candidate transfer paths according to the preset direction of the current excitation source and the current target point.

[0032] The advantage of this setting is that the current transfer path is determined from the candidate transfer paths through the preset direction of the current excitation source and the current target point. Compared with determining a single current transfer path based on the current excitation source and the current target point, it is more detailed and easier to determine the transfer path that causes the hard disk abnormality subsequently, thereby improving the accuracy of the hard disk abnormality analysis results.

[0033] According to another aspect of the present invention, a hard disk abnormality analysis device is provided, the device comprising:

[0034] A current information determination module, used to determine a current excitation source from candidate excitation sources, determine a current target point from candidate target points, and determine a current transfer path from candidate transfer paths according to the current excitation source and the current target point; wherein the candidate excitation source is at least one heat sink of the target server, the candidate target point is at least one hard disk of the target server, and the candidate transfer path is a path formed by a set of connection devices between each of the heat sinks and each of the hard disks;

[0043] The technical solution of the embodiment of the present invention is to take at least one heat sink of the target server as a candidate excitation source, at least one hard disk of the target server as a candidate target point, and the connection device set between each heat sink and each hard disk constitutes a candidate transfer path, so as to facilitate the subsequent vibration transfer analysis that causes hard disk abnormality. By applying target excitation to the current excitation source in a preset non-working state, the current transfer function of the current transfer path is obtained; in a preset working state, the first current response of the current target point to the current excitation source is determined according to the current transfer function and the total response of the first target point; the current path contribution of the current transfer path is determined according to the first current response, and the path contribution of each transfer path can be calculated, so as to facilitate the determination of the specific transfer path that causes the hard disk abnormality according to the contribution of each path, thereby determining the detailed abnormal analysis result of the hard disk. The problem that the cause of the hard disk abnormality cannot be directly determined, and the corresponding structure of the server needs to be randomly improved, and the operation of the hard disk after the structure improvement is detected to determine whether the improvement is correct, which reduces the efficiency of solving the hard disk abnormality problem, and achieves the beneficial effect of improving the accuracy and efficiency of obtaining the hard disk abnormality analysis results.

[0051] Embodiment 1

[0052] Figure 1 This is a flowchart of a hard disk abnormality analysis method provided in the first embodiment of the present invention. This embodiment can be applied to analyzing the situation where the mechanical vibration caused by the operation of the heat dissipation device leads to hard disk abnormality. The method can be executed by the hard disk abnormality analysis device provided in the embodiment of the present invention, and the device can be implemented in software and / or hardware. Figure 1 The hard disk abnormality analysis method provided in this embodiment includes:

[0053] Step 110, determine the current excitation source from the candidate excitation sources, determine the current target point from the candidate target points, and determine the current transfer path from the candidate transfer paths based on the current excitation source and the current target point; wherein the candidate excitation source is at least one heat dissipation device of the target server, the candidate target point is at least one hard disk of the target server, and the candidate transfer path is a path formed by a set of connecting devices between each heat dissipation device and each hard disk.

[0054] The excitation source is a part that causes mechanical vibration, the candidate excitation source is at least one heat sink of the target server, and may be all heat sinks in the target server, and the heat sink may be a heat sink fan, which is not limited in this embodiment. The target server is the server currently concerned, the current excitation source is the excitation source currently concerned, and the current excitation source is determined from the candidate excitation sources, which may be to select any one of the candidate excitation sources as the current excitation source, or to select the excitation sources in sequence according to the positions of the excitation sources as the current excitation source, etc., which is not limited in this embodiment.

[0055] The target point is the position of the vibration response caused by the excitation source. The candidate target point is at least one hard disk of the server, which can be all the hard disks in the server currently concerned. The hard disk can be a front mechanical hard disk, a rear mechanical hard disk, or other hard disks that are abnormally working due to mechanical vibration caused by the operation of the heat dissipation device. This embodiment does not limit this. The current target point is the target point currently concerned. The current target point is determined from the candidate target points. It can be any one of the candidate target points as the current target point, or the target points can be selected in sequence according to the position of the target point as the current target point, etc. This embodiment does not limit this.

[0056] The transmission path is a path for transmitting vibrations composed of the connection devices between the excitation source and the target point. The candidate transmission path is a path composed of the connection device set between each heat sink and each hard disk, that is, a single transmission path is a path composed of the connection device set between a single heat sink and a single hard disk. For example, the heat sink includes ABCD, and the hard disks include 1-6. Then the single transmission path can be a path composed of the connection device set between the heat sink A and the hard disk 1, and can also be a path composed of the connection device set between the heat sink D and the hard disk 2, etc. The connection device set includes at least one connection structure between the heat sink and the hard disk. The connection structure is, for example, a fan compartment, a chassis chassis, a chassis cover, a front hard disk compartment, and a rear hard disk compartment, etc. This embodiment does not limit this.

[0057] After the current excitation source and the current target point are determined, the connection path of the connection device set between the current excitation source and the current target point constitutes the current transfer path. It should be noted that the connection device sets passed by different transfer paths may be the same, but the transfer directions may be different, for example, transfer path A is from the top of the fan compartment to the chassis to the front hard disk compartment, and transfer path B is from the middle of the fan compartment to the chassis to the front hard disk compartment, etc.

[0058] Optionally, the candidate excitation sources, candidate transfer paths, and candidate target points may be changed accordingly based on factors such as servers of different architectures and hard disk locations that require attention.

[0059] Optionally, determining a current transfer path from candidate transfer paths according to a current excitation source and a current target point includes:

[0060] According to the preset direction of the current excitation source and the current target point, the current transfer path is determined from the candidate transfer paths.

[0061] The preset direction is at least one direction related to the current excitation source, for example, three main directions of the XYZ axes of a Cartesian coordinate system constructed with the current excitation source as the origin.

[0062] The current transfer path is determined based on the determined single preset direction and the current target point. The determined current transfer path is the path of vibration transmission composed of the set of connecting devices from the preset direction of the current excitation source to the current target point. Exemplarily, the preset direction is the X-axis direction of the excitation source A, and the current target point is the target point 1. Then the current transfer path is the path of vibration transmission composed of the set of connecting devices from the X-axis direction of the excitation source A to the target point 1. There can be multiple transfer paths between each excitation source and each target point. For example, if the current excitation source is the excitation source A, and the excitation source A has three directions of the XYZ axis, and the current target point is the target point 1, then there are 3 transfer paths between the excitation source A and the target point 1.

[0063] The advantage of this setting is that the current transfer path is determined from the candidate transfer paths through the preset direction of the current excitation source and the current target point. Compared with determining a single current transfer path based on the current excitation source and the current target point, it is more detailed and easier to determine the transfer path that causes the hard disk abnormality subsequently, thereby improving the accuracy of the hard disk abnormality analysis results.

[0064] Step 120: In a preset non-working state, a current transfer function corresponding to the current transfer path is determined by applying a target excitation to the current excitation source.

[0065] Among them, the preset non-working state can be a state in which both the heat dissipation device and the hard disk are in a non-working state, and the hard disk can be replaced with a mold to avoid the hard disk vibration caused by applying excitation to the excitation source, affecting the measurement results such as excitation measurement and response measurement.

[0066] The target excitation is the excitation applied to the current excitation source, so that after the target excitation is applied, the vibration is transmitted from the current excitation source to the current target point along the current transmission path. Exemplarily, the target excitation is the excitation applied to the X-axis direction of the excitation source A, and the current transmission path is the path of the transmission vibration composed of the set of connecting devices from the X-axis direction of the excitation source A to the target point 1. The method and size of applying the excitation are not limited in this embodiment. After applying the excitation to the current excitation source, the sensor corresponding to the current excitation source can read the corresponding reading, such as the acceleration sensor reading the acceleration reading.

[0067] After the target excitation is applied to the current excitation source, the target point generates a response according to the target excitation, and a corresponding reading is read by a sensor corresponding to the current target point, for example, an acceleration reading is read by an acceleration sensor.

[0068] Each transfer path corresponds to a corresponding transfer function, and the current transfer function is the transfer function corresponding to the current transfer path. The form of the transfer function can be determined according to the sensor type corresponding to the current excitation source and the sensor type corresponding to the current target point, such as an acceleration-acceleration transfer function. When the sensor type changes, the form of the transfer function can change accordingly. According to the form of the current transfer function and the preset current transfer function formula, the current transfer function of the current transfer path is determined.

[0069] Optionally, determining a current transfer function corresponding to the current transfer path by applying a target excitation to the current excitation source includes:

[0070] By applying a target excitation to the current excitation source, a second current response of the current target point to the current excitation source is obtained;

[0071] A current transfer function is determined based on the target excitation and the second current response.

[0072] The second current response is the response component caused by applying the target excitation to the current excitation source at the current target point in the preset non-working state, which can be recorded as x ij (ω) represents the response component caused by the current excitation source i at the current target point j in the preset non-working state. The second current response and the target excitation can be directly measured. The target excitation is denoted by F i (ω), represents the target excitation of the current excitation source i.

[0073] The current transfer function is determined based on the target excitation and the second current response, which can be expressed as Determine, where h ij (ω) is the current transfer function between the current excitation source i and the current target point j.

[0074] The advantage of this setting is that by applying the target excitation by the current excitation source in the preset non-working state, the second current response of the current target point to the current excitation source is obtained, and the current transfer function is determined according to the target excitation and the second current response, thereby decoupling the vibration response caused by the overall excitation source, obtaining the transfer function from a single current excitation source to a single current target point, and improving the accuracy of determining the current transfer function.

[0075] Step 130: Under a preset working state, obtain a total response of a first target point, and determine a first current response of a current target point to a current excitation source according to a current transfer function and the total response of the first target point.

[0076] The preset working state can be a state where both the heat sink and the hard disk are in working condition. The total response of the first target point is the response set of all target points under the preset working state, which can be recorded as A j ′, then A j ′=[X 1 ′(ω)X 2 ′(ω)…X j ′(ω)], where X j ′(ω) is the total response of the current target point j to each excitation source in the preset working state, which can be directly measured. After measuring each target point, the total response of the first target point can be obtained by adding the responses of each target point. The first current response is the response component caused by the current excitation source at the current target point, which can be recorded as x ij ′(ω) represents the response component caused by the current excitation source i at the current target point j in the preset working state.

[0077] According to the current transfer function and the total response of the first target point, the first current response of the current target point to the current excitation source is determined. The total excitation of all excitation sources is determined according to the current transfer function and the total response of the first target point including the overall information, and then the total response of the first target point including the first current response is obtained according to a preset formula based on the total excitation of the excitation source and the current transfer function, thereby determining the first current response.

[0078] Step 140: determine a current path contribution of the current transfer path according to the first current response, and determine a hard disk abnormality analysis result according to the current path contribution.

[0079] The path contribution is the contribution of the current transmission path to the hard disk abnormality. The higher the contribution, the greater the impact of the transmission path. The hard disk abnormality is the mechanical vibration caused by the operation of the heat dissipation device, which causes the hard disk to read and write speed reduction and other abnormalities.

[0080] The current path contribution of the current transfer path is determined according to the first current response, and the projection of the first current response in the direction of the total response of the first target point can be used as the current path contribution. The hard disk abnormality analysis result can be a transfer path that has a greater impact on the hard disk abnormality. The hard disk abnormality analysis result is determined according to the current path contribution, and the proportion of the current path contribution in the total path contribution of all transfer paths can be determined. If it is greater than a preset proportion threshold, it indicates that the current transfer path has a greater impact on the hard disk abnormality.

[0081] It is convenient to improve the server structure or add materials according to the hard disk abnormality analysis results. For example, if the current transmission path has a greater impact, the stiffness of the connection device in the current transmission path is changed; or vibration attenuation materials are added in the current transmission path direction of the current excitation source, etc. This embodiment does not limit this. This reduces the vibration transmission level, improves the hard disk working environment, and improves reliability.

[0082] Optionally, also include:

[0083] In response to a hard disk abnormality analysis request, a target rotation speed of a current excitation source under a preset working state is determined.

[0084] Among them, the hard disk abnormality analysis request is used to analyze the hard disk abnormality, and may include target speed information, which may be initiated manually or automatically when the hard disk is abnormal, and this embodiment does not limit this. In response to the hard disk abnormality analysis request, the target speed of the current excitation source in the preset working state is determined. The target speed is the actual speed of the current excitation source in the preset working state, which may be a single speed or multiple speeds, that is, the preset working state may include a single or multiple speeds of the current excitation source. Exemplarily, the target speed may include a preset high speed and a preset low speed.

[0085] The advantage of this setting is that by responding to the hard disk abnormality analysis request, the corresponding target rotation speed is determined, so as to avoid the situation where the rotation speed of the current excitation source corresponding to the preset working state is fixed, and different hard disk abnormalities caused by the current excitation source at different rotation speeds may not be discovered. For example, the current excitation source causes hard disk 1 abnormality at a high rotation speed and hard disk 2 abnormality at a low rotation speed, etc., which affects the comprehensiveness of the hard disk abnormality analysis, thereby improving the accuracy of the hard disk abnormality analysis.

[0086] The technical solution provided in this embodiment uses at least one heat dissipation device of the target server as a candidate excitation source and at least one hard disk of the target server as a candidate target point. The set of connection devices between each heat dissipation device and each hard disk constitutes a candidate transmission path, which facilitates the subsequent vibration transmission analysis that causes hard disk abnormalities.

[0087] By applying the target excitation to the current excitation source in the preset non-working state, the current transfer function of the current transfer path is obtained; in the preset working state, the first current response of the current target point to the current excitation source is determined according to the current transfer function and the total response of the first target point; the current path contribution of the current transfer path is determined according to the first current response, and the path contribution of each transfer path can be calculated, so as to determine the specific transfer path that causes the hard disk abnormality according to the contribution of each path, thereby determining the detailed analysis results of the hard disk abnormality. It solves the problem that the cause of the hard disk abnormality cannot be directly determined, and it is necessary to randomly improve the corresponding structure of the server and detect the hard disk operation after the structure improvement to determine whether the improvement is correct, which reduces the efficiency of solving the hard disk abnormality problem, and achieves the beneficial effect of improving the accuracy and efficiency of obtaining the hard disk abnormality analysis results.

[0088] Embodiment 2

[0089] Figure 2 This is a flowchart of a hard disk abnormality analysis method provided in Embodiment 2 of the present invention. This technical solution is to supplement the process of determining the first current response of the current target point to the current excitation source according to the current transfer function and the total response of the first target point. Compared with the above solution, this solution is specifically optimized to determine the first current response of the current target point to the current excitation source according to the current transfer function and the total response of the first target point, including:

[0090] Construct a transfer function matrix based on the current transfer function;

[0091] Determine the total excitation of the excitation source according to the inverse matrix of the transfer function matrix and the total response of the first target point;

[0092] According to the total excitation of the excitation source and the transfer function matrix, the first current response is determined. Specifically, the flowchart of the hard disk abnormality analysis method is as follows: Figure 2 As shown:

[0093] Step 210, determine the current excitation source from the candidate excitation sources, determine the current target point from the candidate target points, and determine the current transfer path from the candidate transfer paths based on the current excitation source and the current target point; wherein the candidate excitation source is at least one heat dissipation device of the target server, the candidate target point is at least one hard disk of the target server, and the candidate transfer path is a path formed by a set of connecting devices between each heat dissipation device and each hard disk.

[0094] Step 220: In a preset non-working state, a current transfer function corresponding to the current transfer path is determined by applying a target excitation to the current excitation source.

[0095] Step 230: Under a preset working state, obtain a total response of the first target point, and construct a transfer function matrix according to the current transfer function.

[0096] The transfer function matrix is ​​composed of transfer functions in order. For example, the transfer function matrix is ​​denoted as Hij, then

[0097] Step 240: Determine the total excitation of the excitation source according to the inverse matrix of the transfer function matrix and the total response of the first target point.

[0098] The total excitation of the excitation source is the excitation set of all excitation sources under the preset working state, and the total excitation of the excitation source is recorded as B i ′, then B i ′=[F 1 ′(ω)F 2 ′(ω)...F i ′(ω)], where F i ′(ω) is the excitation generated at the current excitation source i under the preset working state.

[0099] The formula can be According to the inverse matrix of the transfer function matrix and the total response of the first target point, the total excitation of the excitation source and the excitations of each excitation source constituting the total excitation of the excitation source are determined. Here, the total response of the first target point A j ', contains and only contains the value of each component, where the component is the target point response of each target point, for example, A j ′=[X 1 ′(ω)X 2 ′(ω)...X j ′(ω)], only X 1 ′(ω),X 2 ′(ω)...X j The value of ′(ω).

[0100] Step 250: Determine the total response of the second target point according to the total excitation of the excitation source and the transfer function matrix, and determine the first current response according to the total response of the second target point.

[0101] According to the total excitation of the excitation source and the transfer function matrix, the first current response can be determined by formula A j =B i ′H ij Get, where A j ″ is the total response of the second target point, and ″ is the total response of the target point including the first current response.

[0102] For example, A j ″=[X 1 ′(ω)X 2 ′(ω)...X j ′(ω)], with X j′(ω) as an example, the total response of the second target point includes components X j ′(ω)x 1j ′(ω), x 2j ′(ω)...x ij ′(ω) value, thus obtaining the first current response x ij ′(ω).

[0103] Step 260: determine a current path contribution of the current transfer path according to the first current response, and determine a hard disk abnormality analysis result according to the current path contribution.

[0104] Determining a current path contribution of a current transfer path according to the first current response includes:

[0105] Obtaining a current target point response of a current target point, and a direction angle between the current target point response and the first current response;

[0106] A current path contribution of the current transfer path is determined according to the first current response and the direction angle.

[0107] Get the current target point response of the current target point, where the current target point response is the above X j ′(ω), which is the total response of the current target point j to each excitation source in the preset working state, can be directly measured.

[0108] Since the current target point response and the first current response are both known, the direction angle between the current target point response and the first current response can be obtained through vector calculation.

[0109] The current path contribution of the current transfer path is determined based on the first current response and the direction angle, which can be obtained by formula C ij ′=|x ij ′(ω)|cosθ i ′ is determined, where C ij ′ is the current path contribution, that is, the response contribution of the current excitation source i to the current target point j, θ i ′ is the angle between the current target point response and the first current response, 0°≤θ i ′≤180°,|x ij ′(ω)| is the modulus of the first current response.

[0110] The advantage of this setting is that the current path contribution of the current transmission path is determined based on the first current response and the directional angle between the current target point response and the first current response, and the projection of the first current response on the total response direction of the first target point is used as the current path contribution, thereby achieving the response contribution of a single current excitation source to a single current target point, which is convenient for subsequent judgment of the excitation source and target point causing the hard disk abnormality based on the current path contribution, narrowing the judgment scope of the hard disk abnormality problem and improving the accuracy of hard disk abnormality analysis.

[0111] Optionally, determine the hard disk abnormality analysis result based on the current path contribution, including:

[0112] Determine the path contribution degree of the current transfer path according to the current path contribution amount and the current target point response;

[0113] The hard disk anomaly analysis result is determined based on the path contribution degree.

[0114] Among them, the path contribution is the proportion of the current transmission path in all responses corresponding to the current target point, which can be obtained by the formula Determine, where ξ ij ′ is the path contribution degree, that is, the ratio of the current path contribution to the modulus of the current target point response of the current target point j is defined as the path contribution degree.

[0115] The hard disk abnormality analysis result is determined according to the path contribution degree, and whether the path contribution degree meets the preset degree threshold can be judged. If so, the current transmission path is determined as an abnormal transmission path, so that corresponding improvements can be made according to the abnormal transmission path in the future.

[0116] The advantage of this setting is that by determining the path contribution of the current transmission path and determining the hard disk anomaly analysis result based on the path contribution, the impact of the transmission path on the hard disk anomaly is made more intuitive, which facilitates rapid positioning of the transmission path that causes the hard disk anomaly and improves the efficiency of hard disk anomaly analysis.

[0117] The embodiment of the present invention constructs a transfer function matrix according to the current transfer function; multiplies the inverse matrix of the transfer function matrix and the total response of the first target point to obtain the total excitation of the excitation source including the decoupled excitation source excitation in the working state; and determines the total response of the second target point according to the total excitation of the excitation source and the transfer function matrix, and obtains the total response of the second target point including the first current response, thereby determining the first current response, thereby solving the problem that the response caused by a single excitation source to a single target point cannot be obtained due to the excitation coupling of the excitation source in the working state.

[0118] In order to enable those skilled in the art to more clearly understand the present solution, the embodiment of the present invention also provides a specific implementation method.

[0119] A heat sink of the target server is determined as the current excitation source, a hard disk of the target server is determined as the current target point, and a path formed by a set of connecting devices of the heat sink and the hard disk is determined as the current transfer path. The transfer path can be determined according to the preset direction of the current excitation source and the current target point, so that a single excitation source and a single target point can correspond to multiple transfer paths.

[0120] In the preset non-working state, the target excitation is applied to the current excitation source, and the current transfer function corresponding to the current transfer path is determined by the following formula:

[0121]

[0122] Among them, h ij (ω) is the current transfer function between the current excitation source i and the current target point j, x ij (ω) is the response component caused by the current excitation source i at the current target point j in the preset non-working state, F i (ω) is the target excitation of the current excitation source i.

[0123] The transfer function matrix is ​​constructed by the current transfer function. The transfer function matrix is ​​composed of transfer functions in order. The transfer function matrix is ​​denoted as H ij ,but

[0124] Under the preset working state, the total response of the first target point is obtained, and the total excitation of the excitation source is determined according to the inverse matrix of the transfer function matrix and the total response of the first target point through the following formula:

[0125]

[0126] Among them, A j ′ is the total response of the first target point, which includes and only includes the target point responses of all target points. j ′=[X 1 ′(ω)X 2 ′(ω)...X j ′(ω)],X j ′(ω) is the current target point j response; B i ′ is the total excitation of the excitation source, B i ′=[F 1 ′(ω)F 2 ′(ω)...F i ′(ω)], where F i ′(ω) is the excitation generated at the current excitation source i under the preset working state.

[0127] Then the total response of the second target point is obtained through the following formula:

[0128] A j =B i ′H ij

[0129] Among them, A j ″ is the total response of the second target point, and ″ is the total response of the target point including the first current response.

[0130] Thus, the first current response is obtained.

[0131] The current target point response of the current target point is directly measured, and the direction angle between the current target point response and the first current response is obtained by vector calculation. The current path contribution of the current transfer path is determined according to the first current response and the direction angle by the following formula:

[0132] C ij ′=|x ij ′(ω)|cosθ i '

[0133] Among them, C ij ′ is the current path contribution, that is, the response contribution of the current excitation source i to the current target point j, θ i ′ is the angle between the current target point response and the first current response, 0°≤θ i ′≤180°,|x ij ′(ω)| is the modulus of the first current response.

[0134] The path contribution degree of the current transfer path is determined according to the current path contribution and the current target point response using the following formula:

[0135]

[0136] Among them, ξ ij ′ is the path contribution degree; |X j ′(ω)| is the modulus of the current target point response.

[0137] Thus, the hard disk abnormality analysis results are determined according to the path contribution degree.
