In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0027] Various modifications and changes can be made to the application in matters of form and details without departing from the spirit and scope of the application, which will be apparent to one skilled in the art. Therefore, the application is intended to cover modifications and variations of the application that come within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the application can be combined with each other without contradiction.

[0028] Before describing the technical solutions provided by the embodiments of the application, the problems existing in the prior art will be specifically described to facilitate the understanding of the embodiments of the application:

[0029] As described above, the inventors of the application have found that a mechanical hard disk, as a highly complex and precise storage device, mainly consists of a disk, a magnetic head, a disk shaft and a control motor. The magnetic head can move along the radial direction of the disk, and, combined with the high-speed rotation of the disk, the magnetic head can be positioned at a specified position of the disk for data read-write operation. All the disks in the mechanical hard disk are mounted on a rotating shaft, and the disks are parallel to each other. There is a magnetic head on the storage surface of each disk, and the distance between the magnetic head and the disk is only 0.01-0.5 μm.

[0030] Due to the complexity and precision of the mechanical hard disk structure, there is a high requirement for the mechanical vibration of the environment during its operation. If the mechanical vibration of the environment exceeds the specifications of the hard disk, it may cause performance degradation of the mechanical hard disk, or even physical permanent damage problems such as damage to the hard disk tracks or the hard disk. In the related art, a structure for hard disk shock protection is usually designed on the case, which increases the material cost. For solid state hard disks, which have high tolerance to vibration, shock protection is not required. Although the structure for hard disk shock protection designed on the case can also protect the mechanical hard disk from shock, it cannot adaptively adjust to the shock protection requirements of the mechanical hard disk and the solid state hard disk, resulting in waste of resources.

[0031] In view of the above research findings of the inventors, the embodiments of the application provide a hard disk shock protection method, device, equipment and computer readable storage medium, which can solve the technical problem that the hard disk cannot be adaptively protected according to its shock protection requirements without increasing the shock protection structure in the prior art.

[0032] Figure 1 is a structural schematic diagram of a hard disk shockproof device provided by an embodiment of the present application, as shown in Figure 1 A plurality of hard disks 106 are inserted on a hard disk backboard 104 of a server 103, a disk array card 102 is connected with the hard disks 106 through the hard disk backboard 104 of the server 103, and a vibration sensor 105 is detachably installed on the hard disk backboard 104. A baseboard management controller 101 is connected with the disk array card 102 through an I2C bus. The baseboard management controller 101 is connected with the vibration sensor 105 through the I2C bus. In addition, the baseboard management controller 101 can also be connected with a platform controller hub (PCH) through an LPC bus (Low pin count Bus) or a universal serial bus (USB), the platform controller hub is connected with a central processing unit (CPU) through a direct media interface (DMI), and the central processing unit is connected with the disk array card 102 through a peripheral component interconnect express (PCIE). The embodiment does not make specific limitation on the connection mode between the baseboard management controller 101 and the disk array card 102 and the vibration sensor 105.

[0033] Figure 2 is a flowchart of a hard disk shockproof method provided by an embodiment of the present application. As shown in Figure 2 The hard disk shockproof method can include the following steps S201 to S204.

[0034] S201, a first connection relationship between a baseboard management controller and a disk array card is established, and a second connection relationship between the baseboard management controller and a vibration sensor is established.

[0035] The baseboard management controller is connected with the disk array card through an I2C bus, and the first connection relationship between the two is established based on the I2C bus; the baseboard management controller is connected with the vibration sensor through the I2C bus, and the second connection relationship between the two is established based on the I2C bus.

[0036] S202, first vibration data of the vibration sensor is acquired.

[0037] The substrate management controller obtains the first vibration data of each hard disk tested by each vibration sensor through an I2C bus or other channels based on the second connection relationship between the substrate management controller and the vibration sensor. The vibration sensor uses the piezoelectric effect of a crystal to complete the vibration test of the hard disk. When the vibration (acceleration) of the tested hard disk forms pressure on the piezoelectric vibration sensor, the crystal element will generate corresponding electric charge, and the number of electric charges can be converted into the vibration parameter. The accuracy and measurement range of the vibration sensor need to meet the actual application scenario, and the selection of the vibration sensor in the embodiment is not specifically limited. Optionally, the vibration sensor used in the embodiment is ST LIS331DL, which is the smallest consumer low-power three-axis linear acceleration sensor of ST, and has an optional I2C / SPI serial interface standard output, supports intelligent embedded functions, and programmable register defines actual application scenario functions. The I2C interface of the device is connected to the substrate management controller through an I2C bus, so that the data interaction between the substrate management controller and the vibration sensor can be realized.

[0038] S203, determining whether the first vibration data is greater than a vibration threshold value of the hard disk matched with the vibration sensor.

[0039] Each hard disk has a vibration sensor matched therewith for testing the first vibration data thereof. The substrate management controller screens out the hard disk whose vibration amplitude or vibration frequency exceeds the corresponding vibration threshold value by determining whether the first vibration data of each hard disk is greater than the vibration threshold value thereof.

[0040] S204, in the case that the first vibration data is greater than the vibration threshold value, sending notification information to a disk array card corresponding to the hard disk, so that the disk array card protects the hard disk.

[0041] Each hard disk has a disk array card corresponding thereto for controlling the corresponding hard disk. When the first vibration data is greater than the vibration threshold value, that is, at least one of the vibration amplitude or the vibration frequency of the hard disk exceeds the corresponding vibration threshold value, the substrate management controller sends notification information to the disk array card corresponding to the hard disk through an I2C bus or other channels, so that the disk array card protects the hard disk controlled thereby. When the first vibration data is less than or equal to the vibration threshold value, that is, the vibration amplitude and the vibration frequency of the hard disk are less than or equal to the corresponding vibration threshold value, the substrate management controller continues to obtain the first vibration data tested by the vibration sensor through an I2C bus or other channels at regular intervals, and records the vibration data tested by all vibration sensors in a log. According to the vibration data recorded in the log, a time-vibration amplitude curve and a time-vibration frequency curve of the hard disk are drawn.

[0042] In the embodiment of the present application, the vibration sensor is installed on the hard disk backboard of the server, and the disk array card is connected with the hard disk through the hard disk backboard of the server. Thus, in the hard disk shockproof method of the embodiment of the present application, after the baseboard management controller establishes the first connection relationship and the second connection relationship with the disk array card and the vibration sensor respectively, the baseboard management controller acquires the first vibration data of the vibration sensor; it is judged whether the first vibration data is greater than the vibration threshold of the hard disk matched with the vibration sensor; in the case that the first vibration data is greater than the vibration threshold, the notification information is sent to the disk array card corresponding to the hard disk, so that the disk array card protects the hard disk. Therefore, in the embodiment of the present application, through the judgment of the baseboard management controller on the vibration data, it can be determined whether the hard disk needs to be shockproofed, and the hard disk can be protected by the disk array card. The embodiment of the present application decides whether to notify the disk array card to protect the corresponding hard disk from shock according to the vibration data of the vibration sensor without increasing the shockproof structure, flexibly adapts to the shockproof demand, and saves the material cost.

[0043] In some embodiments, before judging whether the first vibration data is greater than the vibration threshold of the hard disk matched with the vibration sensor, the hard disk shockproof method further comprises: acquiring first position information of the hard disk and second position information of the vibration sensor; and matching the hard disk and the vibration sensor according to the first position information and the second position information.

[0044] Exemplarily, before judging whether the first vibration data tested by the vibration sensor is greater than the vibration threshold of the hard disk matched therewith, the baseboard management controller needs to acquire the first position information of each hard disk and the second position information of each vibration sensor through the I2C bus, so as to match the hard disk and the vibration sensor according to the positional relationship between each hard disk and each vibration sensor, so that the baseboard management controller can quickly screen out the hard disk with excessive vibration according to the matching relationship between the hard disk and the vibration sensor after acquiring the first vibration data tested by the vibration sensor.

[0045] In some embodiments, matching the hard disk and the vibration sensor according to the first position information and the second position information specifically comprises: determining the physical distance between the hard disk and the vibration sensor according to the first position information and the second position information; determining the similarity parameter of the hard disk and the vibration sensor according to the physical distance and the pre-determined similarity coefficient; and determining the vibration sensor matched with the hard disk according to the smallest similarity parameter corresponding to the hard disk.

[0046] Exemplarily, the baseboard management controller first calculates the physical distance between each hard disk and each vibration sensor according to the first position information of each hard disk and the second position information of each vibration sensor. When a certain hard disk and a certain vibration sensor are located on different backplanes of the server, although the physical distance between the two is short, the vibration between the two backplanes needs to be indirectly transmitted through the motherboard and the like, which causes the physical distance between the hard disk and the vibration sensor calculated by the baseboard management controller to be relatively reduced. Therefore, the propagation path of the vibration wave on the server needs to be calculated according to the physical structure of the server pre-stored in the baseboard management controller, and a similarity coefficient greater than 1 is pre-determined at the development of the server based on the physical structure of the server and the propagation path of the vibration wave on the server. The product of the physical distance between the hard disk and the vibration sensor and the similarity coefficient is taken as the similarity parameter of the hard disk and the vibration sensor, so as to reduce the influence of the structure of the server on the determination of the physical distance between the hard disk and the vibration sensor. After the similarity parameter of each hard disk and each vibration sensor is determined, the minimum similarity parameter corresponding to each hard disk is obtained, and the vibration sensor corresponding to the minimum similarity parameter of each hard disk is taken as the matched vibration sensor.

[0047] In some embodiments, after the hard disk and the vibration sensor are matched according to the first position information and the second position information, the hard disk shockproof method further includes: matching the new hard disk and the vibration sensor when a new hard disk is inserted into the hard disk backplane; and clearing the matched vibration sensor of the original hard disk when the original hard disk is removed from the hard disk backplane.

[0048] Exemplarily, after the matching of the hard disk and the vibration sensor is completed, if a new hard disk is inserted into the hard disk backplane, the baseboard management controller needs to re-acquire the position information of the hard disk, and calculate the physical distance between the hard disk and each vibration sensor according to the position information of the hard disk and the known second position information of the vibration sensor on the hard disk backplane, so as to calculate the similarity parameter of the hard disk and each vibration sensor according to the similarity coefficient, and further determine the matched vibration sensor of the hard disk. If a certain original hard disk is removed from the hard disk backplane, the baseboard management controller needs to clear the calculation result of the similarity parameter of the hard disk and each vibration sensor, and clear the matched vibration sensor of the hard disk from the original vibration sensor, so as to update the matching relationship of the hard disk and the vibration sensor in real time according to the state of the hard disk and the vibration sensor on the hard disk backplane.

[0049] Figure 3 is a flowchart of another hard disk shockproof method provided by the embodiment of the present application. As shown in Figure 3As shown, according to some embodiments of the present application, optionally, before acquiring the first vibration data of the vibration sensor at S202, the hard disk shockproof method provided by the embodiments of the present application can further include steps S301-S304.

[0050] S301, detecting whether the host of the server is powered on and the vibration sensor is in place.

[0051] Before starting a hard disk monitoring thread, the baseboard management controller needs to determine through the I2C bus that the host of the server has been powered on and the vibration sensor has been in place. If the baseboard management controller detects that the host of the server has been powered off during the hard disk monitoring thread, the ongoing hard disk monitoring thread is ended.

[0052] S302, acquiring the model information of the hard disk through the disk array card under the condition that the host is powered on and the vibration sensor is in place.

[0053] Under the condition that the host of the server has been powered on and the vibration sensor has been in place, the baseboard management controller acquires the information of the hard disk through the disk array card, and determines the model of the mechanical hard disk inserted on the hard disk backplane according to the obtained information, so that the baseboard management controller can specifically protect the mechanical hard disk in the hard disk.

[0054] S303, determining the vibration specification data of the hard disk according to the model information.

[0055] The baseboard management controller stores a vibration specification data table of various mechanical hard disks supported by the server, and according to the model of the mechanical hard disk, the vibration specification data corresponding to the mechanical hard disk of each model can be determined from the vibration specification data table.

[0056] S304, determining the vibration threshold of the hard disk according to the vibration specification data.

[0057] The vibration specification data mainly includes the model, vibration amplitude and vibration frequency of the mechanical hard disk. The baseboard management controller can determine the vibration amplitude and vibration frequency corresponding to the mechanical hard disk of the model from the vibration specification data table according to the model of the mechanical hard disk, and further determine the vibration amplitude threshold and vibration frequency threshold of the mechanical hard disk of the model. If multiple models of mechanical hard disks are inserted on the hard disk backplane of the server, the baseboard management controller needs to record the vibration amplitude threshold and vibration frequency threshold of each model of mechanical hard disk.

[0058] In some embodiments, the notification information that the first vibration data is greater than the vibration threshold and the vibration specification data of the hard disk are sent to the disk array card corresponding to the hard disk, so that the disk array card reduces the rotation speed of the hard disk according to the notification information and the vibration specification data.

[0059] Exemplarily, when the first vibration data acquired by the baseboard management controller is greater than the vibration threshold of the corresponding hard disk, i.e., at least one of the vibration amplitude or the vibration frequency of the hard disk exceeds the corresponding vibration threshold, a vibration exceeding trigger event log is recorded by the baseboard management controller, and the hard disk vibration amplitude exceeding or vibration frequency exceeding notification information and the vibration specification data of the hard disk are sent to the disk array card corresponding to the hard disk. The disk array card protects the hard disk from shock according to the notification information and the vibration specification data of the hard disk, for example, reduces the rotation speed of the hard disk, so that the vibration amplitude and the vibration frequency of the hard disk return to the vibration specification data.

[0060] Figure 4 is a flow diagram of another hard disk shockproof method provided by an embodiment of the present application. As shown in Figure 4 According to some embodiments of the present application, after the notification information is sent to the disk array card corresponding to the hard disk to make the disk array card protect the hard disk when the first vibration data is greater than the vibration threshold at S204, the hard disk shockproof method provided by the embodiments of the present application can further include the following steps S401 to S403.

[0061] S401, acquiring second vibration data of the vibration sensor.

[0062] S402, judging whether the second vibration data is less than or equal to the vibration threshold.

[0063] S403, in the case that the second vibration data is less than or equal to the vibration threshold, sending the notification information to the disk array card to make the disk array card stop protecting the hard disk.

[0064] After the disk array card protects the hard disk from shock according to the notification information and the vibration specification data of the hard disk sent by the baseboard management controller, the baseboard management controller needs to acquire the second vibration data of the vibration sensor again, and judge whether the second vibration data is less than or equal to the vibration threshold of the hard disk. When the second vibration data is less than or equal to the vibration threshold, i.e., the vibration amplitude and the vibration frequency of the hard disk are less than or equal to the corresponding vibration threshold, the baseboard management controller sends the notification information to the disk array card corresponding to the hard disk through the I2C bus or other channels, to notify the disk array card to stop protecting the hard disk controlled by it from shock. When the second vibration data is still greater than the vibration threshold, i.e., at least one of the vibration amplitude or the vibration frequency of the hard disk does not return to the corresponding vibration specification data, the baseboard management controller continues to acquire the second vibration data tested by the vibration sensor periodically through the I2C bus or other channels until the second vibration data is less than or equal to the vibration threshold.

[0065] In some embodiments, the notification information is sent to the disk array card to stop the disk array card from protecting the hard disk, specifically including: sending the notification information that the second vibration data is less than or equal to the vibration threshold to the disk array card, so that the disk array card resumes the rotation speed of the hard disk according to the notification information.

[0066] For example, when the second vibration data obtained by the baseboard management controller is less than or equal to the vibration threshold of the corresponding hard disk, that is, the vibration amplitude and the vibration frequency of the hard disk are less than or equal to the corresponding vibration threshold, a vibration exceeding standard release event log is recorded by the baseboard management controller, and the vibration amplitude and the vibration frequency of the hard disk are restored to the vibration specification data, and the notification information that the vibration exceeding standard is released is sent to the disk array card corresponding to the hard disk. The disk array card stops the shock protection of the hard disk according to the notification information, for example, restores the rotation speed of the hard disk.

[0067] Based on the hard disk shockproof method provided in the above embodiments, correspondingly, the application also provides another specific implementation of a hard disk shockproof device. Please see the following embodiments.

[0068] Firstly, referring to Figure 5 The other hard disk shockproof device 50 provided by the embodiments of the application includes the following modules:

[0069] The establishing module 501 is configured to establish a first connection relationship between the baseboard management controller and the disk array card, and a second connection relationship between the baseboard management controller and the vibration sensor. The disk array card is connected with the hard disk through the hard disk backboard of the server, and the vibration sensor is installed on the hard disk backboard.

[0073] In the embodiment of the present application, the vibration sensor is installed on the hard disk backboard of the server, and the disk array card is connected with the hard disk through the hard disk backboard of the server. Thus, in the hard disk shockproof device of the embodiment of the present application, after the baseboard management controller establishes the first connection relationship and the second connection relationship with the disk array card and the vibration sensor respectively, the baseboard management controller acquires the first vibration data of the vibration sensor; it is judged whether the first vibration data is greater than the vibration threshold of the hard disk matched with the vibration sensor; in the case that the first vibration data is greater than the vibration threshold, the notification information is sent to the disk array card corresponding to the hard disk, so that the disk array card protects the hard disk. Therefore, in the embodiment of the present application, through the judgment of the baseboard management controller on the vibration data, it can be determined whether the hard disk needs to be shockproof, and the hard disk can be protected by the disk array card. The embodiment of the present application decides whether to notify the disk array card to protect the corresponding hard disk from shock according to the vibration data of the vibration sensor without increasing the shockproof structure, flexibly adapts to the shockproof demand, and saves the material cost.
