Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of SSD power consumption management, and particularly relates to a SSD dynamic power consumption management method and device, computer equipment and a storage medium. BACKGROUND
[0002] With the evolution of the solid state disk (SSD) interface technology to the PCIe Gen5 generation, the peak performance of consumer SSDs continues to improve, but is accompanied by a significant increase in power consumption. The PCIe Gen5 SSD products currently on the market can be divided into multiple levels according to the performance upper limit, and there are obvious differences in peak power consumption performance among SSDs of different levels, and the higher the performance of the product, the higher the power consumption output.
[0003] However, the existing SSD interface protocol (such as NVMe) has not defined any function characteristics that allow the host to dynamically configure the power consumption upper limit. Limited by this, the SSD products on the market all lack the ability to actively control the power consumption threshold. This technical gap leads to a double dilemma for host manufacturers in product design: on the one hand, in order to ensure hardware compatibility, the power supply module must be designed according to the highest peak power consumption specified in the SSD product manual, even if this power consumption only occurs in extreme load scenarios; on the other hand, strict material classification management is required for SSDs of different power consumption levels to match the power supply capacity of specific host products. This not only increases the complexity of host hardware design and material management costs, but also limits the flexibility of differentiated product design.
[0004] For end users, this technical defect also causes compatibility risks. When users replace or upgrade SSDs on their own, if the peak power consumption of the new device exceeds the carrying capacity of the original host power supply module, it is easy to cause abnormal operation of the device and even hardware damage. In the existing solution, there is no protocol layer mechanism to prevent such risks, nor is there a standardized means to achieve power consumption adaptation.
[0005] In summary, the existing technology has the following core defects:
[0006] Protocol layer function missing: lack of host-configurable SSD power consumption management interface, unable to dynamically constrain peak power consumption;
[0007] System design rigidity: host manufacturers are forced to design power supply modules with maximum redundancy, which increases costs and restricts innovation;
[0008] Insufficient compatibility protection: there is a risk of exceeding the power consumption limit when users replace SSDs, affecting device reliability.
[0009] These defects collectively constitute a technical bottleneck that restricts the coordinated development of SSD technology in high-performance and low-power consumption scenarios. SUMMARY

[0048] Referring to Figure 1 The embodiment of the application provides a dynamic power consumption management method of SSD, which comprises the following steps:
[0049] S1, determining the power consumption gear of the SSD.
[0050] In specific implementation, the SSD is provided with multiple power gears, such as 5W, 8W, 10W, etc., which are not specifically limited by the application. The power consumption gear of the SSD can be set by the user according to actual needs.
[0051] For example, in some preferred embodiments, the above step "determining the power consumption gear of the SSD" specifically comprises the following steps: receiving a power consumption gear configuration instruction; and configuring the power consumption gear of the SSD based on the power consumption gear configuration instruction.
[0052] In specific implementation, the power consumption gear configuration instruction is issued by the host, and the SSD receives the power consumption gear configuration instruction and configures the power consumption gear of the SSD based on the power consumption gear configuration instruction.
[0053] Specifically, the NVME protocol allows manufacturers to implement specific functions through a custom SET FEATURE command, and the Feature command defined in the application is shown in Table 1. The host can set the power consumption mode of the SSD through the command according to its own working scene requirements.
[0054] Table 1. NVMe Set Feature command definition table
[0055]
[0056]
[0057] In the application, by receiving and responding to the power consumption gear configuration instruction issued by the host, the dynamic programmable capability of the system-level power consumption strategy is given:
[0058] Host-led power consumption strategy: the host can send a configuration instruction to switch the SSD gear according to the real-time power supply state (such as battery power less than 20%) or performance requirement (such as starting game mode). For example, after switching from 7W balanced gear to 5W energy-saving gear, the total token number of the token bucket is reduced synchronously, so that the SSD can immediately respond to the system power saving requirement without relying on hardware modification.
[0059] Cross-platform standardized management: the instruction interface provides a channel for OS layer unified power consumption management. The Windows power management module can directly issue a gear instruction through the NVMe drive, so that SSDs of different manufacturers follow the same power saving strategy, eliminating the fragmentation problem caused by private interfaces and simplifying the material management cost of OEM manufacturers.
[0060] S2, determining the total token number of the token bucket based on the power consumption gear.
[0061] In specific implementation, the total token number of the token bucket is determined according to the power consumption gear of the SSD, and the total token number refers to the maximum number of tokens that the token bucket can contain.
[0062] For example, in some preferred embodiments, the above step of "determining the total token number of the token bucket based on the power consumption gear" specifically includes the following steps: obtaining a preset gear-total token number mapping relationship; determining the total token number corresponding to the power consumption gear based on the gear-total token number mapping relationship.
[0063] In the embodiment of the application, the quantitative design based on the preset gear-total token number mapping relationship ensures the accuracy and scalability of power consumption control. The mapping relationship converts the abstract power consumption value (such as 7W) into the discrete total token number (such as 7000 tokens), and the adjustment of the power consumption threshold can be realized by increasing the number of gears (such as adding a 6W gear).
[0064] S3, initializing the token bucket based on the total number of tokens, wherein after the initialization, the token bucket contains the total number of tokens.
[0065] In specific embodiments, the token bucket is initialized based on the total number of tokens, and specifically, after the initialization, the token bucket contains the total number of tokens.
[0066] S4, determining the target number of tokens required by the host command if the host command is received.
[0067] In specific embodiments, the target number of tokens required by the host command is determined after the host command is received. Specifically, the power consumption value (i.e., power consumption contribution coefficient) required by each host command is measured in advance, and the quotient of the power consumption value of the host command and the reference power consumption value corresponding to each token is calculated to obtain the target number of tokens required by the host command.
[0068] For example, in some preferred embodiments, the above step of "determining the target number of tokens required by the host command" specifically includes the following steps: determining the power consumption contribution coefficient corresponding to the host command based on the type of the host command; and determining the target number of tokens required by the host command based on the power consumption contribution coefficient.
[0069] In specific embodiments, the power consumption contribution coefficients corresponding to different types of host commands are measured in advance, and the target number of tokens required by the host command is further determined based on the power consumption contribution coefficients. Specifically, a preset power consumption contribution coefficient-token number mapping relationship is obtained; and the target number of tokens corresponding to the power consumption contribution coefficient is determined based on the power consumption contribution coefficient-token number mapping relationship.
[0070] In some preferred embodiments, the method further includes: measuring the power consumption contribution coefficient corresponding to a host command of a preset type through experiments.
[0071] In specific embodiments, as shown in Table 2, referring to a typical SSD high-load working scenario, appropriate test tools and corresponding configuration items are selected, performance data and SSD power consumption data are recorded during the test process, and a performance-power consumption curve diagram as shown in FIG. 1 is generated. Figure 2

[0074] Based on the SSD power performance curve, the power consumption contribution coefficient of NAND FLASH data access under different models is calculated, and the formula is: power consumption contribution coefficient = power consumption / performance x unit command data volume calculation, and the results are shown in Table 3 (the performance and power consumption data in Table 3, the NAND FLASH access model is related to the master control design and medium parameters, and the correct data needs to be obtained according to different SSD designs).

[0077] S5, determining whether the remaining number of tokens in the token bucket is greater than or equal to the target token number.
[0078] In specific implementation, after determining the target token number required by the host command, it is determined whether the remaining number of tokens in the token bucket is greater than or equal to the target token number.
[0079] S6, if the remaining number of tokens in the token bucket is greater than or equal to the target token number, the target token number of tokens is allocated to the host command, and the host command is executed.
[0080] In specific implementation, if the remaining number of tokens in the token bucket is greater than or equal to the target token number, the target token number of tokens is allocated to the host command, and the host command is executed.
[0081] Further, in some preferred embodiments, the method further comprises: if it is detected that the host command execution is completed, releasing the tokens occupied by the host command to the token bucket.
[0082] In specific implementation, the closed-loop mechanism of releasing tokens when the host command is completed maintains the dynamic balance of the token bucket. The principle is: the tokens occupied during the execution of each command represent a "temporary power quota", and the tokens are returned to the bucket immediately after the command is completed (such as returning 3 tokens when the write command is completed), so that the subsequent command can reuse the quota.
[0083] For example, when the SSD continuously executes multiple write commands, token recycling and timely replenishment can avoid a long waiting queue; and when the burst load ends, the tokens can be quickly accumulated to respond to new requests. The effect realizes the sustainability of power consumption control - it allows instantaneous load to break through the average power consumption (as long as the tokens are sufficient), and can also constrain the long-term power level through the recycling mechanism, achieving the optimal balance between performance and power consumption.
[0084] S7, if the remaining number of tokens in the token bucket is less than the target token number, the host command is added to a preset command waiting queue.
[0085] In a specific implementation, if the remaining number of tokens in the token bucket is less than the target token number, the host command is added to a preset command waiting queue, and the host command is executed when the remaining number of tokens in the token bucket is greater than or equal to the target token number.
[0086] In some preferred embodiments, the method further comprises: detecting the temperature of the SSD; and reducing the total number of tokens in the token bucket if the temperature of the SSD is greater than a preset temperature threshold.
[0087] In a specific implementation, the temperature threshold can be set by those skilled in the art, and the present application does not specifically limit it. When the temperature of the SSD is greater than the preset temperature threshold, the total number of tokens in the token bucket is reduced, for example, by 10%-50% in proportion, and the present application does not specifically limit it. Further, when the temperature falls below the threshold, the original total number of tokens is restored.
[0088] In a specific implementation, the temperature-triggered total token number reduction mechanism increases the level of overheat protection. When the temperature sensor detects that the SSD exceeds the threshold (such as NAND flash > 85℃), the system automatically reduces the total token number (for example, from 100 to 70), which is equivalent to temporarily shrinking the upper limit of power consumption. The principle is that high temperature is often caused by continuous high power consumption (such as full-disk backup scenario), and reducing the token number will force the subsequent command to enter the waiting queue, giving the heat dissipation module time to recover. This design creates a double protection: on the basis of protocol layer flow control, hardware state feedback is superimposed, for example, when the SSD overheats due to poor heat dissipation, it automatically downshifts (such as 15W→10W) without the need for host intervention, preventing data loss or device damage caused by thermal runaway. The final effect is to improve the robustness of the system under extreme conditions, especially suitable for thermal management scenarios of compact devices.
[0089] The embodiment of the application provides a kind of SSD dynamic power consumption management method, comprising: determining the power consumption gear of SSD;Total token number of token bucket is determined based on the power consumption gear;Total token number is based on the initialization token bucket of the total token number, wherein, after initialization, the token number contained in the token bucket is equal to the total token number;If a host command is received, determine the target token quantity required by the host command;Judge whether the remaining number of tokens in the token bucket is greater than or equal to the target token quantity;If the remaining number of tokens in the token bucket is greater than or equal to the target token quantity, allocate the target token quantity of tokens for the host command, and execute the host command;If the remaining number of tokens in the token bucket is less than the target token quantity, add the host command to the preset command waiting queue.The SSD dynamic power consumption management method builds a three-level linkage mechanism of power consumption gear-token quantization-command execution, and actively restricts the maximum power consumption of the solid state disk for the first time in the protocol layer.The technical effect is specifically shown as follows: by determining the SSD power consumption gear to establish the basic control parameter, the host can set the power consumption upper limit threshold according to the system power supply capacity or heat dissipation demand, and solve the defect that the host must design the power supply module according to the maximum redundant power consumption of the SSD in the traditional scheme from the root;The process of determining the total token number of the token bucket based on the power consumption gear converts the physical power consumption into a quantifiable virtual resource, forming a token budget pool strictly corresponding to the power consumption upper limit;Initialization full token bucket ensures that the initial state has complete power consumption quota, laying a foundation for dynamic allocation.When the host command arrives, determine the target token quantity required by the command to realize the differentiated power consumption measurement of different operation types, so that heterogeneous loads such as reading and writing can accurately match their actual energy consumption characteristics;Token remaining amount judgment and allocation mechanism constitute the core control closed loop: if the remaining token is sufficient, immediately allocate and execute the command to guarantee real-time performance utilization rate;If the token is insufficient, the command is moved to the waiting queue, and the instantaneous power consumption peak is forcedly restricted by delayed execution.This design essentially builds a flow control system based on token feedback model-the total token quantity is limited by power consumption gear, command execution consumes tokens equivalent to power consumption quota, and command queuing mechanism forms negative feedback regulation, which ensures that the actual power consumption of SSD is always less than or equal to the gear setting value.Finally, it breaks through the bottleneck of prior art: host manufacturers can be free from the dependence on the nominal peak power consumption of SSD, and flexibly configure the power consumption gear according to product form (such as thin and light notebook or server), significantly reducing the design redundancy and material management cost of power supply module;When terminal user replaces SSD, the system automatically restricts the power consumption of new equipment according to the preset gear, and completely eliminates the compatibility risk caused by power consumption overrun;At the same time, it creates a new dimension for differentiated product design, such as realizing dynamic conversion of "performance mode" and "silent mode" by gear switching on the same hardware platform, promoting the coordinated development of high performance and low power consumption scenarios.
