Description

Technical Field

[0001] The present invention relates to the technical field of solid state drives, and in particular, to a method and device for controlling the data transfer rate of a solid state drive. Background Art

[0002] With the rapid development of information technology, solid state drives (SSDs) have been widely used in the computer storage field. The data transfer rate of solid state drives is crucial for the performance of the entire computer system.

[0003] Traditional methods for controlling the data transfer rate of solid state drives are mainly based on fixed rate settings or threshold judgments. Based on fixed rate settings, a fixed upper limit of the data transfer rate is set according to the model or nominal speed of the solid state drive. Regardless of the actual operating conditions of the system, the data transfer will not exceed this set value. However, the fixed rate setting lacks flexibility and cannot adapt to the dynamic requirements for data transfer rates in different application scenarios. Based on the threshold control method, when the temperature or queue depth of the solid state drive reaches a certain threshold, the data transfer rate is adjusted. However, the threshold control is often too simple and rough, and the rate adjustment is only based on a single threshold, which is prone to misjudgment. Moreover, different solid state drives have differences in heat dissipation performance, internal architecture, etc., and a unified threshold setting cannot achieve precise rate control.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present invention.

[0060] Refer to Figure 1 as shown in Figure 1 is a flowchart of the solid-state drive data transfer rate control method provided by the present invention. In the embodiments of the present invention, the execution subject of the solid-state drive data transfer rate control method is a transfer rate control device. Therefore, the solid-state drive data transfer rate control method includes:

[0061] Step 10, collect the current internal state parameters and current operating load information of the target solid-state drive.

[0062] Optionally, the transmission rate control device collects the current internal state parameters and current operating load information of the target solid-state drive in real time. Among them, the current internal state parameters include the current temperature, current cumulative usage duration, current write amplification factor, and current queue depth. The current internal state parameters can reflect the comprehensive state index and performance bottleneck of the solid-state drive. For example, a higher temperature may mean that the solid-state drive is operating under high load and the transmission rate needs to be adjusted appropriately to avoid overheating; an excessively high write amplification factor may indicate that the storage cells of the solid-state drive are under greater pressure, and the data write rate also needs to be optimized and controlled.

[0063] Optionally, the current operating load information includes the current CPU usage rate, current memory occupancy rate, and the application program types of the currently running applications. Among them, the currently running applications can include system tool applications, network communication applications, and entertainment creation applications. Therefore, the application program types include system tool program types, network communication program types, and entertainment creation program types. Different types of application programs have quite different requirements for data transmission rates. For example, game applications usually require fast and stable data reading rates to ensure smooth screen rendering, while background data backup programs can run at a relatively low rate.

[0064] Step 20: Determine the comprehensive state index of the target solid-state drive based on the current temperature, current cumulative usage duration, current write amplification factor, and current queue depth.

[0065] Furthermore, the transmission rate control device determines the comprehensive state index of the target solid-state drive according to the current temperature, current cumulative usage duration, current write amplification factor, and current queue depth, as specifically described in Steps 210 to 203.

[0067] Optionally, a preset model library is pre-constructed in the transmission rate control device of the embodiment of the present invention. Among them, the preset model library includes multiple data transmission evaluation models, and the adaptation situations of each data transmission evaluation model are different. Each data transmission evaluation model is trained based on the sample CPU usage rate, sample memory occupancy rate, and their corresponding data transmission pressure ability label results. Therefore, the transmission rate control device matches the target data transmission evaluation model most suitable for the current situation in the preset model library, as specifically described in Steps 301 to 304.

[0068] Step 40: Input the current CPU usage rate and current memory occupancy rate into the target data transmission evaluation model to obtain the current data transmission pressure ability output by the target data transmission evaluation model.

[0069] Further, the transmission rate control device inputs the current CPU usage rate and the current memory occupancy rate into the target data transmission evaluation model, and obtains the current data transmission pressure capacity output by the target data transmission evaluation model, where the value range of the current data transmission pressure capacity is from 0 to 1, specifically as described in steps 401 to 403.

[0070] Step 50: Control the data transmission rate of the target solid-state drive based on the current data transmission pressure capacity and the application program type.

[0071] Further, for different application program types, the transmission rate control device controls the data transmission rate of the target solid-state drive according to the current data transmission pressure capacity and the application program type, specifically as described in steps 501 to 503.

[0072] In the embodiment of the present invention, the comprehensive status index determined by the current temperature, the current cumulative usage duration, the current write amplification factor, and the current queue depth of the target solid-state drive is used to match the target data transmission evaluation model most suitable for the current situation in the preset model library. The current data transmission pressure capacity of the target solid-state drive is evaluated through the target data transmission evaluation model in combination with the current CPU usage rate and the current memory occupancy rate, which improves the accuracy of the data transmission rate control of the solid-state drive. At the same time, the data transmission rate of the target solid-state drive is controlled in combination with the current data transmission pressure capacity and the application program type, so that when facing different application program types, the target solid-state drive performs data transmission at different data transmission rates, which improves the flexibility of the data transmission rate control of the solid-state drive.

[0073] In one embodiment, the descriptions of steps 210 to 203 are as follows:

[0074] Step 201: Determine the operation influence factor of the temperature on the target solid-state drive based on the current temperature.

[0075] Optionally, the transmission rate control device determines the operation influence factor of the temperature on the target solid-state drive according to the current temperature, and the specific formula is as follows:

[0076]

[0077] where T f represents the operation influence factor, T represents the current temperature, μ T and σ T respectively represent the mean and variance values of the normal working temperature of the solid-state drive.

[0078] Step 202: Evaluate the life of the target solid-state drive based on the current cumulative usage duration and the set total life value of the target solid-state drive, and obtain the current remaining life prediction value of the target solid-state drive.

[0079] Further, the transmission rate control device evaluates the lifespan of the target solid-state drive according to the current cumulative usage duration and the set total lifespan value of the target solid-state drive, and obtains a current remaining lifespan prediction value of the target solid-state drive. The specific formula is as follows:

[0080]

[0081] Among them, L f represents the current remaining lifespan prediction value, L represents the set total lifespan value, e represents the base of the exponential function, and t represents the current cumulative usage duration.

[0082] Step 203: Calculate a comprehensive status index of the target solid-state drive based on the current remaining lifespan prediction value, the operation impact factor, the current write amplification factor, and the current queue depth.

[0083] Further, the transmission rate control device calculates a comprehensive status index of the target solid-state drive according to the current remaining lifespan prediction value, the operation impact factor, the current write amplification factor, and the current queue depth. The specific formula is as follows:

[0084]

[0085] Among them, S f represents the comprehensive status index, W f represents the current write amplification factor, K Q represents a preset scaling coefficient, and Q f represents the current queue depth.

[0086] In the embodiment of the present invention, the target data transmission evaluation model most suitable for the current situation is matched in the preset model library through the comprehensive status index. Therefore, the current data transmission pressure capacity of the target solid-state drive can be evaluated by combining the target data transmission evaluation model with the current CPU usage rate and the current memory occupancy rate, improving the accuracy of the solid-state drive data transmission rate control.

[0087] In one embodiment, the descriptions of steps 301 to 304 are as follows:

[0088] Step 301: Determine a state stability index based on the comprehensive status index, determine a state change rate based on the state stability index, and determine a state fluctuation coefficient based on the state change rate.

[0089] Optionally, the transmission rate control device calculates a state stability index S stable , among which, the specific calculation formula of the state stability index S stable is as follows:

[0090] S stable = 1 / [1 + exp(Sf )].

[0091] Optionally, the state change rate reflects how fast the state changes over time and is related to the state stability index. Therefore, the transmission rate control device calculates the state change rate S based on the state stability index. rate , where the state change rate S rate has the following specific calculation formula:

[0092]

[0093] where represents the state stability index at the previous moment, represents the state stability index at the current moment.

[0094] Optionally, the state fluctuation coefficient is used to measure the intensity and uncertainty of state changes. In one embodiment, the sequence of state change rates over a period of time is where s represents the dimension of the state change rate sequence S rate (t). Therefore, the transmission rate control device calculates the state change rate variance S rate based on the state change rate sequence S V (t), and the specific formula is as follows:

[0095]

[0096] Furthermore, the transmission rate control device calculates the state fluctuation coefficient S V based on the state change rate variance S fluctuate , where the specific calculation formula of the state fluctuation coefficient S fluctuate is as follows:

[0097]

[0098] Step 302: Based on the state stability index, the state change rate, and the state fluctuation coefficient, construct a working state feature vector of the target solid-state drive.

[0099] Step 303: Based on the working state feature vector, match it with the model feature vectors of each data transmission evaluation model in the preset model library to determine the final matching degree of the working state feature vector to the model feature vectors of each data transmission evaluation model.

[0100] Further, the transmission rate control device fuses the state stability index, the state change rate, and the state fluctuation coefficient to construct a working state feature vector of the target solid-state drive. Further, the transmission rate control device matches the working state feature vector with the model feature vectors of each data transmission evaluation model in the preset model library to determine the final matching degree of the working state feature vector to the model feature vectors of each data transmission evaluation model, as specifically described in steps 3031 to 3033.

[0101] Step 304: Determine the data transmission evaluation model corresponding to the maximum final matching degree as the target data transmission evaluation model.

[0102] Further, the transmission rate control device traverses all the final matching degrees and determines the data transmission evaluation model corresponding to the maximum final matching degree as the target data transmission evaluation model.

[0103] In the embodiment of the present invention, the target data transmission evaluation model most suitable for the current situation is matched in the preset model library through comprehensive state indicators. Therefore, the current data transmission pressure capacity of the target solid-state drive can be evaluated by combining the target data transmission evaluation model with the current CPU usage rate and the current memory occupancy rate, improving the accuracy of the solid-state drive data transmission rate control.

[0104] In one embodiment, the descriptions of steps 3031 to 3033 are as follows:

[0105] Step 3031: Determine the adaptation degree of the working state feature vector to the model feature vectors of each data transmission evaluation model based on the vector distance between the working state feature vector and the model feature vectors of each data transmission evaluation model.

[0106] Optionally, the working state feature vector in the embodiment of the present invention is represented as X = {x1, x2, x3}, where, for example, x1 represents the state stability index, x2 represents the state change rate, and x3 represents the state fluctuation coefficient. There are m data transmission evaluation models in the preset model library, where the m data transmission evaluation models can be represented as M = {M1, M2,..., M m}, and the model feature vector of each data transmission evaluation model M i can be represented as M i = {M i1 , M i2 , M i3}, i = 1, 2,.., m, where M i1 , M i2 , M i3 respectively represent the relevant eigenvalue of the state stability index, the state change rate, and the state fluctuation coefficient of the data transmission evaluation model M i .

[0110] Further, the transmission rate control device determines the adaptation degree of the working state feature vector to the model feature vector of each data transmission evaluation model according to the vector distance between the working state feature vector and the model feature vector of each data transmission evaluation model. The specific formula is as follows:

[0111]

[0112] where represents the adaptation degree of the working state feature vector X to the model feature vector of the M i -th data transmission evaluation model. It can be understood that when the vector distance is relatively small, is close to 1, indicating that the adaptation degree of the working state feature vector X to the model feature vector of the M i -th data transmission evaluation model is high; when the vector distance is relatively large, is close to 0, indicating that the adaptation degree of the working state feature vector X to the model feature vector of the M i -th data transmission evaluation model is low.

[0113] Step 3032: Determine the model influence factor of each data transmission evaluation model based on the feature correlation and feature similarity between the model feature vector of each data transmission evaluation model and the model feature vectors of other data transmission evaluation models.

[0114] Further, the transmission rate control device obtains the feature correlation between the model feature vector of each data transmission evaluation model and the model feature vectors of other data transmission evaluation models, and the feature similarity between the model feature vector of each data transmission evaluation model and the model feature vectors of other data transmission evaluation models, where other data transmission evaluation models refer to other models in the preset model library except for itself for each data transmission evaluation model. The feature correlation can be calculated according to the Pearson correlation coefficient method, and the feature similarity can be calculated by the cosine similarity method.

[0115] Further, the transmission rate control device determines the model influence factor of each data transmission evaluation model according to the feature correlation and feature similarity between the model feature vector of each data transmission evaluation model and the model feature vectors of other data transmission evaluation models. The specific formula is as follows:

[0116] I i =α*Corr(M i ,M j )+(1-α 2 )*Sim(M i ,M j ),i≠j。

[0117] Wherein, I i represents the model influence factor of the M i th data transmission evaluation model, Corr(M i ,M j ) represents the feature correlation between the M i th data transmission evaluation model and the M j th data transmission evaluation model, Sim(M i ,M j ) represents the feature similarity between the M i th data transmission evaluation model and the M j th data transmission evaluation model, and α represents a preset coefficient.

[0118] Step 3033: Determine the final matching degree of the working state feature vector to the model feature vector of each data transmission evaluation model based on the adaptation degree of the working state feature vector to the model feature vector of each data transmission evaluation model and the model influence factor of each data transmission evaluation model.

[0119] Further, the transmission rate control device calculates the final matching degree of the working state feature vector to the model feature vector of each data transmission evaluation model according to the adaptation degree of the working state feature vector to the model feature vector of each data transmission evaluation model and the model influence factor of each data transmission evaluation model. The specific formula is as follows:

[0120]

[0121] Among them, represents the final matching degree of the working state feature vector X to the model feature vector of the M i th data transmission evaluation model, and β represents a preset adjustment parameter.

[0122] In the embodiment of the present invention, the working state feature vector of the target solid-state drive constructed by the state stability index, the state change rate, and the state fluctuation coefficient is used to determine the final matching degree with each data transmission evaluation model in the preset model library. Therefore, the target data transmission evaluation model that is most suitable for the current situation can be accurately matched according to the final matching degree. Therefore, the current data transmission pressure capacity of the target solid-state drive can be evaluated by combining the current CPU usage rate and the current memory occupancy rate through the target data transmission evaluation model, improving the accuracy of the solid-state drive data transmission rate control.

[0123] In one embodiment, the target data transmission evaluation model in the embodiment of the present invention includes a basic influence factor calculation layer, an interaction influence factor calculation layer, and a transmission pressure capacity calculation layer. Therefore, the descriptions of steps 401 to 403 are as follows:

The basic influence factor calculation layer calculates the first basic influence factor of the CPU usage rate on the data transmission pressure and the second basic influence factor of the memory occupancy rate on the data transmission pressure according to the current CPU usage rate and the current memory occupancy rate.

[0125] Optionally, the current CPU usage rate in the embodiment of the present invention is CPU usage , and its value range is between 0 and 100; the current memory occupancy rate is Memory usage , and the value range is between 0 and 100. For the convenience of subsequent calculations, the current CPU usage rate and the current memory occupancy rate are normalized to obtain the normalized CPU usage rate Y1 and the normalized memory occupancy rate Y2. The specific formulas are as follows:

[0126] Y1 = CPU usage / 100; Y2 = Memory usage / 100.

[0127] Optionally, the transmission rate control device inputs the current CPU usage rate and the current memory occupancy rate into the target data transmission evaluation model. Based on the basic influence factor calculation layer, according to the current CPU usage rate and the current memory occupancy rate, it calculates the first basic influence factor of the CPU usage rate on the data transmission pressure and the second basic influence factor of the memory occupancy rate on the data transmission pressure. The specific formulas are as follows:

[0128]

[0129] Among them, F CPU represents the first basic influence factor, and F men represents the second basic influence factor.

[0130] Step 402: Based on the interaction influence factor calculation layer, according to the current CPU usage rate and the current memory occupancy rate, calculate the interaction influence factor of the CPU usage rate and the memory occupancy rate on the data transmission pressure.

[0131] Furthermore, the interaction influence factor calculation layer calculates the interaction influence factor of the CPU usage rate and the memory occupancy rate on the data transmission pressure according to the current CPU usage rate and the current memory occupancy rate. The specific formula is:

[0132]

[0133] Among them, F inter represents the interaction influence factor.

[0134] Step 403: Based on the transmission pressure capacity calculation layer, according to the first basic influence factor, the second basic influence factor, and the interaction influence factor, calculate the current data transmission pressure capacity.

[0135] Furthermore, the transmission pressure capacity calculation layer calculates the current data transmission pressure capacity P according to the first basic influence factor, the second basic influence factor, and the interaction influence factor. The specific formula is as follows:

[0136] P = F CPU + F men + F inter .

[0137] In the embodiment of the present invention, by using the target data transmission evaluation model to combine the current CPU usage rate and the current memory occupancy rate to evaluate the current data transmission pressure capacity of the target solid-state drive, the accuracy of the data transmission rate control of the solid-state drive is improved.

[0138] In one embodiment, the descriptions of steps 501 to 503 are as follows:

[0139] Step 501, if the application type is a system tool program type, then based on the current data transmission pressure capacity, the maximum data transmission rate, and the minimum data transmission rate of the target solid-state drive, determine the first current data transmission rate of the target solid-state drive, and control the data transmission rate of the target solid-state drive at the first current data transmission rate.

[0140] Optionally, application programs of the system tool type usually have relatively high requirements for data timeliness and stability. Under different data transmission pressures, it is necessary to reasonably adjust the data transmission rate of the solid-state drive. Therefore, if it is determined that the application type is a system tool program type, the transmission rate control device obtains the maximum data transmission rate and the minimum data transmission rate of the target solid-state drive, and determines the first current data transmission rate of the target solid-state drive according to the current data transmission pressure capacity, the maximum data transmission rate, and the minimum data transmission rate, and controls the data transmission rate of the target solid-state drive at the first current data transmission rate. That is, when the target solid-state drive transmits the data of the system tool program, it transmits the data of the system tool program at the first current data transmission rate. The calculation formula for the first current data transmission rate is as follows:

[0141]

[0142] Wherein, R sys represents the first current data transmission rate, R min represents the minimum data transmission rate, R max represents the maximum data transmission rate, and P represents the current data transmission pressure capacity.

[0143] Step 502, if the application type is a network communication program type, then based on the current data transmission pressure capacity, the maximum data transmission rate, the minimum data transmission rate, and the network delay coefficient, determine the second current data transmission rate of the target solid-state drive, and control the data transmission rate of the target solid-state drive at the second current data transmission rate.

[0144] Optionally, application programs of the network communication type have certain requirements for the timeliness and continuity of data transmission, and at the same time, they need to take into account the network environment and data transmission pressure. Therefore, if it is determined that the application type is a network communication program type, the transmission rate control device obtains the maximum data transmission rate and the minimum data transmission rate of the target solid-state drive, and the network delay coefficient of the network. Among them, the value range of the network delay coefficient is from 0 to 1, and the higher the network delay, the greater the network delay coefficient.

[0145] Further, the transmission rate control device determines the second current data transmission rate of the target solid-state drive according to the current data transmission pressure capacity, the maximum data transmission rate, the minimum data transmission rate, and the network delay coefficient, and controls the data transmission rate of the target solid-state drive at the second current data transmission rate. That is, when the target solid-state drive transmits the data of the network communication program, it transmits the data of the network communication program at the second current data transmission rate. The calculation formula of the second current data transmission rate is as follows:

[0146]

[0147] Where, R net represents the second current data transmission rate, and L represents the network delay coefficient.

[0148] Step 503, if the application program type control includes the entertainment creation program type, then based on the current data transmission pressure capacity, the maximum data transmission rate, the minimum data transmission rate, and the user experience sensitivity coefficient, determine the third current data transmission rate of the target solid-state drive, and control the data transmission rate of the target solid-state drive at the third current data transmission rate.

[0149] Optionally, entertainment creation type application programs usually have a large bandwidth requirement for data transmission, but when the data transmission pressure is large, reasonable rate adjustment is also required to ensure the user experience. Therefore, if it is determined that the application program type control includes the entertainment creation program type, the transmission rate control device obtains the maximum data transmission rate and the minimum data transmission rate of the target solid-state drive, as well as the user experience sensitivity coefficient of the user to the experience. The value range of the user experience sensitivity coefficient is from 0 to 1. The higher the user's sensitivity to the experience, the larger the user experience sensitivity coefficient.

[0150] Further, the transmission rate control device determines the third current data transmission rate of the target solid-state drive according to the current data transmission pressure capacity, the maximum data transmission rate, the minimum data transmission rate, and the user experience sensitivity coefficient, and controls the data transmission rate of the target solid-state drive at the third current data transmission rate. That is, when the target solid-state drive transmits the data of the entertainment creation program, it transmits the data of the entertainment creation program at the third current data transmission rate. The calculation formula of the third current data transmission rate is as follows:

[0151]

[0152] Where, R ent represents the third current data transmission rate, and S represents the user experience sensitivity coefficient.

[0153] An embodiment of the present invention controls the data transmission rate of a target solid-state drive in combination with the current data transmission pressure capacity and the application program type, so that when facing different application program types, the target solid-state drive performs data transmission at different data transmission rates, improving the flexibility of data transmission rate control of the solid-state drive.
