Specifically, the invention designs a monitoring module for determining an abnormal state of a Solid State Disk (SSD), wherein the module can acquire state information of the SSD, and the monitoring module comprises: temperature data, attitude data and path data of the solid state disk, wherein the attitude data comprises inclination angle data measured by a gyroscope and acceleration measured by an inertial measurement unit (Inertial Measurement Unit, IMU), whether the SSD is in a tremble state or is impacted can be inferred, the path of the solid state disk is a channel between the NAND and a main control chip of the solid state disk, after power-on, if the data read from the NAND by the main control chip is not wrong, the path is considered to be normal, and the inertial measurement unit can be an accelerometer.
The SSD is normally powered on to operate, the monitoring module is started along with the SSD and always acquires state information such as temperature data and attitude data of the SSD, and the data read from the temperature sensor, the IMU and the access are normal.
Step S102, comparing the value of the state information with a corresponding preset threshold value to obtain a comparison result.
Specifically, in the running process of the SSD, the monitoring module compares the temperature data and the gesture data in the state information with corresponding preset thresholds respectively to obtain a comparison result. If the comparison result shows that the temperature data is larger than the corresponding preset threshold value, the temperature of the solid state disk is possibly abnormal; if the comparison result shows that the gesture data is larger than the corresponding preset threshold value, the solid state disk is likely to be impacted by continuous environmental tremble or large force.

Specifically, if the monitoring module can determine that the temperature data of the solid state disk is abnormal according to the comparison result, the abnormal information is uploaded to the main control chip of the solid state disk, the main control chip firstly reduces the power consumption of the solid state disk, then the current new temperature data of the solid state disk are obtained again, if the new temperature data show that the temperature of the solid state disk is reduced, the solid state disk is normal, if the temperature of the solid state disk is not reduced, the solid state disk is abnormal, and the main control chip generates alarm information and sends the alarm information to a user.
Step S104, if the attitude data of the solid state disk is abnormal according to the comparison result, the access information and the read-write performance information of the solid state disk are obtained, and an abnormality judgment result of the solid state disk is obtained according to the access information and the read-write performance information.
Specifically, if the monitoring module can determine that the posture data of the solid state disk is abnormal according to the comparison result, the abnormal information, the acquired access information and the read-write performance information are uploaded to the main control chip of the solid state disk, the main control chip judges whether the read-write performance of the solid state disk is normal according to the access information and the read-write performance information, if the read-write performance of the solid state disk is normal, if the read-write performance of the solid state disk is abnormal, the main control chip generates alarm information and sends the alarm information to a user.
According to the method for determining the abnormal state of the solid state disk, the numerical value of the state information is compared with the corresponding preset threshold value to obtain the comparison result, whether the current state of the SSD is stable or not is judged according to the comparison result, the abnormal state of the solid state disk is fed back to a user in time, and reliability and safety of the SSD in running are improved. The method solves the problems that in the related technology, personnel are required to analyze the task actively and judge whether the task needs to be executed immediately, and timeliness and reliability of task processing cannot be guaranteed.
In some alternative embodiments, comparing the value of the state information with a corresponding preset threshold value to obtain a comparison result includes:
comparing the temperature data with a first preset threshold value to obtain a first comparison result;
comparing the first quantity of inclination angles in the gesture data with a second preset threshold value to obtain a second comparison result;
comparing the second plurality of accelerations in the gesture data with a third preset threshold value to obtain a third comparison result;
comparing the second plurality of accelerations with a fourth preset threshold value to obtain a fourth comparison result, wherein the fourth preset threshold value is larger than the third preset threshold value;
and obtaining a comparison result according to the first comparison result, the second comparison result, the third comparison result and the fourth comparison result.
Specifically, during the running process of the solid state disk, the temperature sensor monitors the working temperature of SSD NADN FLASH, transmits temperature data to the detection module, and the detection module compares the temperature data with a first preset threshold value to obtain a first comparison result, wherein the first preset threshold value is as follows: 80 degrees celsius.
The gyroscope monitors a first number of tilt angles of the solid state disk, the first number representing a plurality of, for example: if there is an angle of inclination in each of the x-axis, y-axis, and z-axis, the first number is 3. Transmitting the inclination angles to a detection module, and comparing the first quantity of inclination angles in the gesture data with a second preset threshold value by the detection module to obtain a second comparison result, wherein the second preset threshold value is as follows: 5 degrees.
The inertial measurement unit detects a second number of accelerations of the solid state disk, the second number representing a plurality of, for example: if there is acceleration in each of the x, y, and z axes, the second number is 3. The acceleration is transmitted to a detection module, and the detection module compares the second number of accelerations in the gesture data with a third preset threshold value to obtain a third comparison result, wherein the third preset threshold value is as follows: 0.2g, g is gravitational acceleration.
In addition, the detection module may further compare the second number of accelerations with a fourth preset threshold value, to obtain a fourth comparison result, where the fourth preset threshold value is greater than the third preset threshold value, and the fourth preset threshold value is, for example: 1g, g is gravitational acceleration. If the acceleration is larger than a fourth preset threshold value, the solid state disk can be determined to be impacted with larger force.
The monitoring module gathers the first comparison result, the second comparison result, the third comparison result and the fourth comparison result to obtain comparison results, and uploads the comparison results to the main control chip.
In this embodiment, the detection module compares the temperature data, the inclination angle and the acceleration in the state information with corresponding preset thresholds to obtain a comparison result, so that the main control module can conveniently determine whether the current state of the SSD is stable, and if the current state of the SSD is unstable, the abnormal state of the solid state disk can be further determined.
In some optional embodiments, if it is determined that the temperature data of the solid state disk is abnormal according to the comparison result, after reducing power consumption of the solid state disk, acquiring new temperature data, and obtaining an abnormality determination result of the solid state disk according to the new temperature data, where the determining includes:
if the first comparison result in the comparison results is that the temperature data is larger than a first preset threshold value, the temperature data of the solid state disk is abnormal;
selecting a target storage unit from storage units in a working state in the solid state disk, and controlling the target storage unit to enter an idle state;
acquiring current temperature data of the solid state disk, and judging whether the current temperature data is smaller than a first preset threshold value or not;
if the current temperature data is not smaller than the first preset threshold value, selecting a target storage unit from the storage units in the working state in the solid state disk to start to execute subsequent steps until the repetition time reaches a preset time period, stopping, and judging whether the current temperature data is smaller than the first preset threshold value;
if the current temperature data is not smaller than the first preset threshold value, determining that the abnormality is the abnormality according to the abnormality judgment result, and sending first warning information.
Specifically, if the first comparison result in the comparison results is that the temperature data is greater than a first preset threshold, the temperature data of the solid state disk is abnormal, and the first preset threshold is, for example: 80 degrees celsius. The main control module can reduce the power consumption of the solid state disk and judge whether the temperature of the solid state disk can be reduced.
The main control module selects a target storage unit from storage units in a working state (namely an active state) in the solid state disk, and controls the target storage unit to enter an idle state, wherein the storage units are as follows: NAND FLASH LUNs, which are the smallest individual units within a flash memory (NAND FLASH) that can execute commands and report their own status. And along with the reduction of the number of active LUNs, the temperature sensor can acquire the current temperature data of the solid state disk again, the current temperature data is uploaded to the detection module, and the detection module judges whether the current temperature data is smaller than a first preset threshold value or not. If the current temperature data is not smaller than the first preset threshold value, the main control module reselects a target storage unit from storage units in a working state in the solid state disk, controls the target storage unit to enter an idle state, and repeats the process. If the temperature of the device solid state disk is reduced in the repetition process, the solid state disk is normal. If the repetition process reaches a preset time period, stopping and judging whether the current temperature data is smaller than a first preset threshold value, wherein the preset time period is as follows: 10 minutes or any duration within 3-10 minutes. If the current temperature data is still not smaller than the first preset threshold, which means that the temperature of the solid state disk is not reduced or even is always increased, the abnormality judgment result is that abnormality is determined, and first warning information is sent to the user, for example: and turning on the warning lamp and sending prompt information to the user. The first warning information is to transmit the abnormal information to the user in a message mode to prompt the user that the temperature of the SDD working environment is abnormal at the moment.
The above is shown in fig. 2: the temperature sensor measures the temperature according to NAND FLASH, the temperature high/low uploading monitoring module and the detecting module determine that the temperature is normal/abnormal, and upload the result of the temperature normal/abnormal to the main control, the main control determines whether the solid state disk is abnormal by reducing or increasing the number of active luns, if so, the warning lamp is turned on, if not, the warning lamp is turned off, prompt information is sent to the user, and the abnormal information is transmitted to the user in a message mode.
In the embodiment, under the condition that the temperature data of the solid state disk is abnormal, the main control chip reduces the power consumption of the solid state disk by controlling the target storage unit to enter an idle state, judges whether the temperature of the solid state disk is reduced, if the temperature is reduced, the solid state disk is normal, and if the temperature is not reduced, the solid state disk is abnormal, and the method is simple, convenient and easy to implement and has high efficiency.
In some alternative embodiments, controlling the target storage unit to enter an idle state includes:
stopping sending the operation command to the target storage unit;
and after the historical operation command of the target storage unit is executed, the target storage unit enters an idle state.
Specifically, the master control module stops sending the operation command to the target storage unit, for example: some NAND FLASH LUNs. When the historical operation command of the target storage unit is executed, and the target storage unit does not receive a new operation command, the target storage unit enters an idle state. For example: normally, one channel of the solid state disk has 16 LUNs in a working state, when the temperature rises, the main control chip can use a software control method to send no command to an appointed LUN, such as LUN 0, the LUN can enter an idle state, and the solid state disk can reduce power consumption.
In this embodiment, the transmission of the operation command to the target storage unit is stopped, and the target storage unit is controlled to enter the idle state. The power consumption of the solid state disk can be reduced rapidly, and the abnormal state of the solid state disk can be determined conveniently.
In some optional embodiments, if the posture data of the solid state disk is determined to be abnormal according to the comparison result, obtaining the access information and the read-write performance information of the solid state disk, and obtaining an abnormality judgment result of the solid state disk according to the access information and the read-write performance information, where the method includes:
if the second comparison result in the comparison results is that at least one inclination angle is larger than a second preset threshold value and the first time is larger than a fifth preset threshold value, and the third comparison result in the comparison results is that at least one acceleration is larger than a third preset threshold value and the second time is larger than the sixth preset threshold value, the attitude data of the solid state disk are abnormal, wherein the first time is the time when the inclination angle is in a first interval, and the second time is the time when the acceleration is in a second interval;
if the fourth comparison result in the comparison results is that at least one acceleration is larger than a fourth preset threshold value, the attitude data of the solid state disk is abnormal;
Judging whether the data interface connection of the solid state disk is normal or not under the condition that the attitude data of the solid state disk is abnormal;
if the data access is normal, a target window of the whole data access of the solid state disk is obtained, wherein the data access utilizes the target window to transmit data;
if the number of the target windows is equal to a seventh preset threshold value, determining that the target windows are abnormal according to the abnormal judgment result, and sending second warning information;
if the number of the target windows is larger than a seventh preset threshold value, acquiring the read-write performance error of the solid state disk;
if the read-write performance error is larger than the eighth preset threshold, determining that the error is abnormal according to the abnormal judgment result, and sending second warning information.
Specifically, the IMU is used as an SSD internal measurement chip and comprises an accelerometer and a gyroscope, so that the attitude data of the SSD can be measured at any time. Although SSD has shell protection, the inside is the electronic device, and long-time tremble or instantaneous external force impact can all influence the internal structure, and whether current operational environment is steady static can be deduced through the gesture information of SSD that IMU measured.
The attitude data includes a plurality of inclination angles, for example: the roll, pitch, yaw angle of the SSD, and the attitude data also contains a plurality of accelerations. If a second one of the comparison results is that there is at least one tilt angle greater than a second preset threshold, for example: 5 degrees, and the first time of the first interval in which the inclination angle is in the vicinity of the second preset threshold value is greater than a fifth preset threshold value, for example, 12 hours, 24 hours, etc., and the third comparison result of the comparison results is that there is at least one acceleration greater than the third preset threshold value and the second time is greater than the sixth preset threshold value, the third preset threshold value being, for example: and 0.2g, the main control chip can judge that the attitude data of the solid state disk is abnormal when the SSD works in a tremble environment. The first interval is for example: 4.5 degrees-5.5 degrees, if the tilt angle is continuously in the first interval, it means that the tilt angle fluctuates around 5 degrees. The second interval is for example: 0.18g-0.22g, if the acceleration continues to lie in the second interval, indicating that the acceleration fluctuates around 0.2 g.
If a fourth comparison result of the comparison results shows that at least one acceleration measured on one or more of the three axes of the accelerometer of the IMU at a time SSD is greater than a fourth preset threshold, for example: 1g, the main control chip can determine that the solid state disk is impacted with a large force, and the attitude data of the solid state disk is abnormal.
Under the condition that the attitude data of the solid state disk is abnormal, the main control chip judges whether the data interface connection of the solid state disk is normal, checks whether the SSD data interface is connected well, and if the interface is completely plugged, if the interface is plugged well, the PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) interface of the SSD is wrongly reported.
If the connection of the data interfaces is normal, the main control chip acquires a target window of the whole data path of the solid state disk, wherein the data path transmits data by using the target window, the target window represents a usable window value of the whole data path, if the number of the target windows is equal to a seventh preset threshold value, the whole path has no usable window value, the abnormal condition of the path is indicated, an abnormal judgment result is that the abnormality is determined, and second warning information is sent, and the seventh preset threshold value is, for example: 0. the second warning information is used for informing the user that the SSD is affected by tremors or impacts and the like during working, prompting the user to change the working environment of the SDD and checking the internal structure of the SSD and stored data. The second warning information is for example: and turning on the corresponding warning lamp and sending prompt information to the user.
If the number of the target windows is greater than a seventh preset threshold, the number of the target windows indicates that the whole channel has a usable window value, the basic read-write performance of the solid state disk can be further analyzed, the basic read-write performance is that the speed of the solid state disk for reading data and writing data is represented as XXMB/s, the SSD can set a read-write speed standard according to different capacities and operating frequencies, the standard can be set in a code, if abnormality occurs in monitoring, the read-write speed at the current moment can be tested, and the read-write performance error of the read-write speed at the current moment relative to the read-write speed standard is calculated. The main control chip obtains the read-write performance error of the solid state disk, if the read-write performance error is larger than an eighth preset threshold, the basic read-write performance of the solid state disk is abnormal, the use requirement cannot be met, the abnormal judgment result is that the determination is abnormal, and the second warning information is sent, wherein the eighth preset threshold is as follows: 3%.
The above process is shown in fig. 3: the measured value exceeds a threshold value, the IMU transmits the measured value to a monitoring module, the monitoring module determines that the gesture is abnormal, the gesture abnormal information is sent to a main control, the main control checks NAND FLASH interface, a passage and read-write performance are checked, if the main control determines that the SSD gesture is abnormal, a warning lamp is turned on, if the main control determines that the SSD gesture is normal, the warning lamp is turned off, prompt information is sent to a user, and the abnormal information is transmitted to the user in a message mode.
In this embodiment, under the condition that the posture data of the solid state disk is abnormal, the main control chip firstly determines whether the data interface connection of the solid state disk is normal, then determines whether the whole data path has a target window to transmit data, and finally determines whether the error of the read-write performance of the solid state disk is too large, and obtains the abnormal determination result of the solid state disk by combining multiple factors.
In some optional embodiments, obtaining a target window of an entire data path of the solid state disk includes:
scanning preset parameters of a data path by using a preset program, wherein the data path comprises a third number of windows, the scanning of the preset parameters comprises changing the numerical value of the preset parameters, and acquiring the parameters read by each window;
and taking the window with the read parameters consistent with the preset parameters as a target window.
Specifically, the preset program is such as: a path scanning procedure, preset parameters such as: the phy parameters refer to parameters of a physical layer, which are used for describing physical characteristics of a network interface or a transmission medium, the data path includes a third number of windows, the third number represents a plurality of windows, and the path scanning procedure is a procedure capable of changing a value of a preset parameter and acquiring the parameter read by each window. Scanning the preset parameters of the data path by using a preset program, changing the numerical value of the phy parameter when scanning each channel, acquiring the parameters read by each window, testing the correctness of the window read data by comparing whether the parameters are consistent with the phy parameters, and taking the window with the read parameters consistent with the preset parameters as a target window. Typically, when the phy parameter is changed, each channel has a window with a read error of zero, for example, the phy scans from 0 to 10, the number of read errors is 0 between 4 and 7, which indicates that the target window is 4 to 7, if the channel has a target window, it indicates that the channel is normal, and if the channel has no target window, it indicates that the channel is abnormal.
In this embodiment, a preset program is used to scan preset parameters of the data path, determine whether the entire path includes a target window, and determine whether the entire path is affected by vibration or impact through the target window, so as to determine whether the performance of the path is normal.
In some optional embodiments, obtaining the read-write performance error of the solid state disk includes:
acquiring the current read-write rate and the preset read-write rate of the solid state disk;
and obtaining the read-write performance error according to the current read-write speed and the preset read-write speed.
Specifically, the read-write rate can be measured in the SSD operation, and the error can be obtained by comparing the actual rate with the standard rate. The main control chip obtains the current read-write rate and the standard read-write rate of the solid state disk, namely the preset read-write rate, and the preset read-write rate represents the normal rate in the running process of the solid state disk. Comparing the current read-write rate with a preset read-write rate, for example: the current read-write rate is subtracted by the preset read-write rate, and the difference is divided by the preset read-write rate to obtain the read-write performance error.
In this embodiment, according to the current read-write rate and the preset read-write rate, the read-write performance error is obtained, and whether the basic read-write performance of the solid state disk is affected by vibration or impact is determined according to the read-write performance error, so that the abnormality judgment result is more accurate.

If the temperature data is abnormal, the main control chip reduces the power consumption, judges whether the temperature is reduced, if the temperature is reduced, SSD is normal, and if the temperature is not reduced, the warning lamp gives an alarm to inform the upper computer. If the gesture data is abnormal, the main control chip judges whether the data path is normal, and if the data path is abnormal, the warning lamp gives an alarm and informs the upper computer; if the data path is normal, judging whether the read-write speed is normal, and if the read-write speed is normal, the SSD is normal; if the read-write speed is abnormal, the warning lamp gives an alarm to inform the upper computer.
