[0063] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

For example, A and / or B may represent: A exists alone, B exists alone, and A and B exist at the same time. In addition, unless otherwise specified, the term "multiple" means two or more. For example, multiple systems refers to two or more systems, and multiple terminals refers to two or more terminals.
[0066] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "include", "comprises", "has" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.
[0067] With the rapid development of the Internet and cloud technology, data has exploded. Solid-state drives (SSDs) have been widely used in computing devices or high-performance storage systems due to their low read and write latency and high bandwidth.
[0068] In high-performance storage systems, such as cloud computing platforms, a large number of enterprises or individuals use cloud services, which leads to an increasing amount of data in the storage system of the cloud computing platform. The working frequency of the SSD is high, which leads to a rapid increase in the power consumption of the SSD, thereby increasing the power consumption of the cloud computing platform.
[0069] Currently, there are two ways to reduce SSD power consumption.
[0070] In one case, if Figure 1 As shown in FIG. 1 , when there is no IO service on the host side, the host sends a power-saving instruction to the SSD, so that the entire SSD enters a power-saving working mode. In this working mode, the SSD needs to shut down corresponding components, such as shutting down some physical links between the storage chip and the host, the power management unit (Power Management Unit, PMU) powers off the dynamic random access memory (Dynamic Random Access Memory, DRAM), and all the storage chips of the PMU. However, the SSD entering the power-saving working mode will affect the IO latency. For example, in the Non-Volatile Memory Express (NVMe) / PCIe framework, it takes microseconds to milliseconds for the SSD to enter or exit different levels of low-power modes, and the power-on initialization time of the DRAM and storage chips increases the latency of processing IO requests. In addition, in high-performance storage systems such as cloud computing platforms, since services need to be continuously provided to users, the host side needs to continuously have IO requests to interact with the SSD, resulting in a relatively small chance that the SSD enters a power-saving working mode.
[0071] In another case, if Figure 2 As shown in the figure, when there is IO service on the host side, the power consumption of the SSD can be reduced by reducing the operating frequency or voltage of the components in the SSD. However, the bandwidth of existing network services is volatile, and a large amount of IO load will fall on the storage chip in the SSD. Reducing the operating frequency or operating voltage of the SSD will cause the performance of the SSD to degrade, and then cause the IO latency of the SSD to increase when burst IO services occur.
[0072] Based on this, an embodiment of the present application proposes a power consumption control method for a solid-state drive. The method determines the timing of adjusting the SSD to enter a low power consumption mode by monitoring the parameter values of the target parameters of the SSD in real time. Among them, adjusting the SSD to enter a low power consumption mode includes adjusting the data in the SSD to be stored in the first storage chip, and all storage chips in the SSD except the first storage chip enter a state where IO data is not processed, thereby reducing the number of storage chips that process IO data, reducing the power consumption of the SSD, and avoiding increasing IO latency. This is just a brief description of the method. For details about the method, see the description below.
[0073] Next, a system for controlling the power consumption of a solid-state hard disk that may be applied to the power consumption control method of the solid-state hard disk provided in an embodiment of the present application is introduced. Figure 3 The embodiment of the present application provides a power consumption control method for a solid state drive, which can be applied to Figure 3 As shown in the system architecture diagram. Figure 3 As shown, the power consumption control system of the solid state drive includes a load monitoring module 301 , a power consumption management module 302 and a data layout module 303 .
[0074] The load monitoring module 301 is used to determine the parameter value of the target parameter of the SSD in real time. The target parameter can measure the current load of the SSD, that is, the amount of data processed by the SSD. For example, the target parameter can be a target parameter such as the bandwidth of the SSD in a continuous time, the amount of data in the SSD, the number of read and write operations performed by the SSD per second in a continuous time, etc.
[0075] The power management module 302 is used to determine whether the SSD enters the low power mode according to the parameter value of the target parameter. In the case that the SSD needs to enter the low power mode, an instruction is sent to the data layout module 303. After receiving the instruction, the data layout module 303 adjusts the layout of the storage chip of the data in the SSD to reduce the amount of data in the storage chip used to store data. At the same time, the power management module 302 also sends an instruction to the power management module to power off the storage chip that does not store data or enter the standby state.
[0076] In a possible implementation, the load monitoring module 301 , the power consumption management module 302 , and the data layout module 303 may be implemented by software.
[0077] In another possible implementation, in the embodiment of the present application, the load monitoring module 301, the power management module 302 and the data layout module 303 can be implemented by hardware. For example, the power management module 302 and the data layout module 303 can be implemented as a control circuit or a chip circuit.
[0078] There are many layout modes for the load monitoring module 301 , the power consumption management module 302 and the data layout module 303 .
[0079] For example, Figure 4a As shown, the load monitoring module 301 and the power consumption management module 302 are both deployed in the host 100 , and the data layout module is deployed in the control chip of the SSD 200 .
[0080] Another exemplary example is, Figure 4b As shown, the load monitoring module 301 , the power consumption management module 302 and the data layout module 303 are all deployed in the control chip in the SSD 200 .
[0081] The host 200 may be a computing device such as a computer or a server. In one example, the server involved in the present solution may be used to provide cloud services, which may be a server or a hyperterminal that can establish a communication connection with other devices and provide computing functions and / or storage functions for other devices. The server involved in the present solution may be a hardware server or may be embedded in a virtualized environment. For example, the server involved in the present solution may be a virtual machine executed on a hardware server including one or more other virtual machines.
[0082] The SSD 100 can be used as a data storage device of the host 200 to store relevant data of the host 200. Specifically, there is a communication link between the SSD 100 and the host 200. Through the communication link, the host 200 can send a data write instruction to the SSD 100, and the control chip 110 in the SSD 100 can respond to the data write instruction and perform a write operation to write relevant data into the storage chip through the write operation to achieve data preservation. Through the communication link, the host 200 can send a data read instruction to the SSD 100, and the control chip 110 in the SSD 100 can respond to the data read instruction and perform a read operation to read data from the storage medium 120, and send the read data to the host 200 through the communication link. Among them, the relevant functions of the control chip 110 may include a write operation, a read operation, a data receiving operation, a data sending operation, etc.
[0083] In some embodiments, the communication link between the host 200 and the SSD 100 may be a PCIe link.
[0084] like Figure 4a or Figure 4b As shown, the SSD includes multiple packages, 01 to 0n, each package includes multiple memory chips. The memory chips communicate with the host through data channels, and the data channels of the memory chips in the same package are the same.
[0085] In the embodiment of the present application, the load in the SSD is monitored by the load monitoring module, and the power management module determines whether the SSD enters the low power mode according to the load of the SSD. When the SSD needs to enter the low power mode, all the cached data in the SSD is adjusted to the first storage chip to reduce the number of storage chips used to process data, and all the second storage chips except the first storage chip enter a state of not processing IO data, and only the first storage chip processes IO data. In this way, the number of storage chips that process IO data is reduced, thereby reducing the power consumption of the SSD.
[0086] Next, a method for controlling power consumption of a solid state drive provided in an embodiment of the present application is introduced in detail.
[0087] Figure 5 is a flow chart of a method for controlling power consumption of a solid state drive provided in an embodiment of the present application. This embodiment can be applied to Figure 3 , Figure 4a or Figure 4b In the system shown. Figure 2 As shown, the power consumption control method of the solid state drive provided in the embodiment of the present application at least includes the following steps S501 and S502.
[0088] S501, determining a parameter value of a target parameter of an SSD, where the target parameter is used to measure the amount of data processed by the SSD, and the SSD includes a plurality of storage chips, and the plurality of storage chips are used to store data.
[0089] The target parameter of the SSD can measure the load of the SSD, that is, the amount of data processed by the SSD. The target parameter may be the bandwidth of the SSD in continuous time, the amount of data in the SSD, the number of read and write operations performed by the SSD per second in continuous time, etc.
[0090] The SSD includes multiple storage chips, and the storage chips are used to store data. Figure 6 As shown, the SSD includes 4 packages, namely 01 to 04, each package includes m memory chips. Before the SSD enters the low power mode, the memory chips used to store data are all memory chips in packages 01, 02, 03 and 04.
[0091] For example, Figure 6 As shown, the load monitoring module in the control chip in the SSD can monitor the load of the SSD. For example, the load monitoring module monitors the bandwidth of the SSD in a continuous time, the amount of data in the SSD, or the number of read and write operations performed by the SSD per second in a continuous time.
[0092] Here, the bandwidth of the SSD can be the bandwidth for writing data or the bandwidth for reading data.
[0093] S502, when the parameter value of the target parameter is lower than the preset parameter threshold, adjusting the SSD to enter the low power consumption mode, wherein adjusting the SSD to enter the low power consumption mode includes: adjusting data to the first storage chip, and controlling the second storage chip to enter the target state, wherein the multiple storage chips include the first storage chip, the second storage chip is a storage chip that does not store data among the multiple storage chips, and the target state is a state where IO data processing is not performed; during the period when the SSD enters the low power consumption mode, the first storage chip is used to process IO data.
[0094] Low power consumption mode refers to a mode in which the power consumption of the SSD is reduced when processing the same amount of data.
[0095] The preset parameter threshold is pre-configured into the SSD. It is understandable that the preset parameter threshold can be changed according to the actual situation. Different target parameters have different parameter thresholds. For example, if the target parameter is the bandwidth of the SSD in a continuous time, then the parameter threshold is 30% of the standard value of the bandwidth. The standard value of the bandwidth is a performance parameter of the SSD and is not specifically limited. If the target parameter is the amount of data in the SSD, then the parameter threshold is 50% of the capacity of the SSD. Here, the above is only used as an example to illustrate the parameter threshold.
[0096] When the target parameter is lower than a preset parameter threshold, the SSD enters a low power consumption mode to operate.
[0097] In a possible implementation, a target parameter may be used to determine when the SSD enters the low power mode. For example, when the bandwidth of the SSD is lower than 40% of the standard value of the bandwidth in a continuous period of time, the SSD is adjusted to enter the low power mode. For another example, when the amount of data in the SSD is lower than 50% of the capacity of the SSD, the SSD is adjusted to enter the low power mode.
[0098] In another possible implementation, the timing of the SSD entering the low power mode may be determined by multiple target parameters. For example, when the bandwidth of the SSD is lower than 40% of the standard value of the bandwidth in a continuous period of time and the amount of data in the SSD is lower than 50% of the capacity of the SSD, the SSD is adjusted to enter the low power mode.
[0099] In an embodiment of the present application, adjusting the SSD to enter a low power mode includes adjusting the layout of data in the SSD to reduce the number of storage chips used to store data. Specifically, adjusting the SSD to enter a low power mode includes storing all data in the SSD in a first storage chip. It is understandable that there is at least one first storage chip. During the process of the SSD operating in a low power mode, the chip storing data is the first storage chip, and the chip not storing data is the second storage chip. The first storage chip is used to process IO data. The second storage chip is in a state where no data processing is performed, such as a sleep state, a power-off state, etc.
[0100] For example, Figure 6 As shown, before entering the low power mode, the storage chips used to store data are all the storage chips in package 01 to package 04. However, the capacity of all the storage chips in package 01 to package 04 is 1024G, while the amount of all the data in the SSD is 408G. Therefore, it is necessary to adjust the SSD to enter the low power mode. Among them, all the data in the SSD are adjusted to the storage chips in package 01 and package 02, and the storage chips in package 03 and package 04 do not store data. In other words, when the SSD enters the low power mode, the storage chips in package 01 and package 02 are the first storage chips, and the storage chips in package 03 and package 04 are the second storage chips. In this way, when the SSD enters the low power mode, IO data is processed only by the storage chips in package 01 and package 02, and package 03 and package 04 enter the sleep state or power-off state.
[0101] Here, Figure 4a Based on the adjustment instruction of the power consumption management module, the PMU can control the second storage chip in the SSD to sleep or power off the second storage chip. Figure 7 As shown, there is a power line 71 and a signal line 72 between the PMU and the storage chip. The PMU supplies power to the storage chip through the power line, and the PMU controls the storage chip through the signal line. As a possible implementation, when the SSD enters the low power mode, the PMU can power off the second storage chip, or the PMU sends a high-level sleep signal to the second storage chip to put the second storage chip into a sleep state. For example, Figure 6 As shown, the power consumption management module sends an adjustment instruction to the PMU, wherein the adjustment instruction includes the identifier of the second storage chip. According to the adjustment instruction, the PMU sends a sleep signal to the storage chip in package 03 and the storage chip in package 04, so that the storage chip in package 03 and the storage chip in package 04 enter a sleep state. Here, controlling the second storage chip to enter a sleep state by a sleep signal is only a possible implementation method, and this embodiment of the present application does not specifically limit this.
[0102] The identifier of the storage chip may be a physical address of the storage chip in the SSD, etc., which is not specifically limited.
[0103] It should be noted that Figure 6 The signal lines in the figure are for illustration only, and the connection method between the signal lines and each memory chip shall be subject to the actual situation.
[0104] In S502, adjusting the SSD to enter the low power consumption mode includes determining a first memory chip. In some embodiments, the first memory chip may be determined from a plurality of memory chips according to the reliability of the memory chip.
[0105] As a possible implementation, the reliability of the memory chip is determined by calculating the remaining service life of each memory chip. Exemplarily, the remaining service life of each memory chip is determined. The service life of the package is calculated, wherein the service life of the package is the average of the remaining service lives of all memory chips in the package. The service life of each package is compared. The greater the service life of the package, the higher the reliability of the memory chip in the package. A first package is determined from a plurality of packages by a top K algorithm, wherein the memory chip in the first package is the first memory chip.
[0106] As another possible implementation, the reliability of the memory chip is determined by the number of errors of the memory chip. Exemplarily, the number of errors of each memory chip is determined. The number of errors of the package is calculated, wherein the number of errors of the package is the average number of errors of all memory chips in the package. The number of errors of each package is compared, and the fewer the number of errors of the package, the higher the reliability of the memory chip in the package. The first package is determined from the multiple packages by the topk algorithm, wherein the memory chip in the first package is the first memory chip.
[0107] As a possible implementation, the reliability of the memory chip is determined by the number of error recovery of the memory chip. Exemplarily, the number of error recovery of each memory chip is determined. The number of error recovery of the package is calculated, wherein the number of error recovery of the package is the average number of error recovery of all memory chips in the package. The number of error recovery of each package is compared. The larger the number of error recovery of the package, the higher the reliability of the memory chip in the package. The first package is determined from the plurality of packages by the top K algorithm, wherein the memory chip in the first package is the first memory chip.
[0108] After determining the first storage chip, the data in the second storage chip is written into the first storage chip. After determining the first storage chip, the power management module sends an adjustment instruction to the data layout module, wherein the adjustment instruction includes the identity of the first storage chip and the identity of the second storage chip. According to the adjustment instruction, the data layout management module sends a read instruction to the second storage chip to read out the data in the second storage chip, and sends a write instruction to the first storage chip to write the read data into the first storage chip. For example, Figure 6 As shown, the data layout module sends a read instruction to the memory chip in package 03 and the memory chip in package 04 to read out the data stored in the memory chip in package 03 and the data stored in the memory chip in package 04. And sends a write instruction to the memory chip in package 01 and the memory chip in package 02 to write the read data into the memory chip in package 01 and the memory chip in package 02.
[0109] Next, the power management module sends an adjustment instruction to the PMU, which carries the identity of the second storage chip. The PMU sends a sleep signal to the second storage chip or powers off the second storage chip according to the adjustment instruction. Figure 6 As shown, the power management module sends an adjustment instruction to the PMU, and the adjustment instruction includes the identity identifiers of all memory chips in package 03 (i.e., 031 to 03m) and the identity identifiers of all memory chips in package 04 (041 to 04m). According to the adjustment instruction, the PMU sends a sleep signal to memory chips 031 to 03m and sends a sleep signal to memory chips 041 to 04m, so that memory chips 031 to 03m and memory chips 041 to 04m enter a standby state.
[0110] According to the embodiment of the present application, Figure 4b Based on this, taking the target parameter being the write bandwidth of the SSD within T consecutive seconds as an example, the power consumption control method of the solid state drive SSD provided in the embodiment of the present application is exemplarily described.
[0111] Figure 8 FIG. 1 is a flow chart of a method for controlling power consumption of a solid state drive (SSD) provided in an embodiment of the present application. Figure 8 As shown, the power consumption control method of the solid state drive SSD provided in the embodiment of the present application includes steps S801 to S814.
[0112] S801, the host monitors the write bandwidth tBW of the SSD in real time.
[0113] S802, the host determines whether the write bandwidth tBW of the SSD within T consecutive seconds is less than 30% of the standard value tBW_0 of the write bandwidth. If yes, execute S803. If no, execute S810.
[0114] S803, the host sends an instruction to the control chip in the SSD to enter a low power consumption mode.
[0115] The write bandwidth can measure the load of the SSD. When the load of the SSD is low, the SSD can enter the low power mode. The low power mode can be described in detail in S501 and will not be described here. When tBM<0.3*tBW_0 for T consecutive seconds, the host sends a command to the control chip of the SSD to enter the low power mode.
[0116] S804, the control chip determines that the SSD is in low power consumption mode. If yes, execute S808. If no, execute S805.
[0117] S805: The control chip determines a first storage chip and a second storage chip.
[0118] The specific process may refer to the specific implementation method of determining the first storage chip in S502, which will not be described in detail here.
[0119] S806, the control chip writes the data in the second storage chip into the first storage chip.
[0120] S807, the control chip sends an adjustment instruction to the PMU, where the adjustment instruction includes the identity of the second storage chip.
[0121] S808: The PMU sends a sleep signal to the second storage chip to put the second storage chip into a sleep state.
[0122] S809: The host sends an IO data request to the SSD according to the bandwidth limit corresponding to the low power consumption mode.
[0123] S810, the host sends an instruction to the control chip in the SSD to enter a normal working mode.
[0124] S811, the control chip determines that the SSD is in a normal working mode. If yes, execute S814, if not, execute S812.
[0125] S812, the control chip sends a power supply instruction to the PMU.
[0126] S813, the PMU supplies power to all storage chips in the SSD.
[0127] S814, the control chip receives the IO data request sent by the host.
[0128] By monitoring the amount of data processed by the SSD, the timing when the SSD needs to enter the low power mode is determined. The SSD entering the low power mode includes adjusting all the data cached in the SSD to the first storage chip to reduce the number of storage chips used to process data, and all second storage chips except the first storage chip enter a state of not processing IO data, and only process IO data through the first storage chip. In this way, the number of storage chips that process IO data is reduced, thereby reducing the power consumption of the SSD.
[0129] Based on the same concept as the embodiment of the method of the present application, the embodiment of the present application also provides a power consumption control device for a solid state drive SSD. The power consumption control device for a solid state drive SSD includes several modules, each of which is used to execute each step in the personal information identification method provided in the embodiment of the present application, and the division of the modules is not limited here. The technicians in the relevant field can clearly understand that in practical applications, the various steps in the power consumption control method for the solid state drive SSD provided in the embodiment of the present application can be assigned to different modules as needed, that is, the internal structure of the device is divided into different modules to complete all or part of the functions described above. Each module in the embodiment can be integrated in a processing unit, or each unit can exist physically separately, or two or more modules can be integrated in one unit, and the above-mentioned integrated unit can be implemented in the form of hardware or in the form of a software functional unit. In addition, the specific names of each module are only for the convenience of distinguishing each other, and are not used to limit the scope of protection of the present application. The specific working process of the module in the above-mentioned device can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.
[0130] For example, the power consumption control device of the solid state drive SSD is used to execute the power consumption control method of the solid state drive SSD provided in the embodiment of the present application. Fig. 9 Schematic diagram of the structure of the power consumption control device of the solid state drive SSD provided in the embodiment of the present application. Fig. 9 As shown, the power consumption control device of the solid state drive SSD provided in the embodiment of the present application includes: a determination module 901 and an adjustment module 902.
[0131] A determination module 901 is used to determine a parameter value of a target parameter of the SSD, where the target parameter is used to measure the amount of data processed by the SSD, and the SSD includes a plurality of storage chips, and the plurality of storage chips are used to store data;
[0132] The adjustment module 902 is used to adjust the SSD to enter a low power consumption mode when the parameter value of the target parameter is lower than a preset parameter threshold value, and the adjustment of the SSD to enter the low power consumption mode includes: adjusting data to a first storage chip, and controlling a second storage chip to enter a target state, wherein the plurality of storage chips include the first storage chip, the second storage chip is a storage chip in which no data is stored in the plurality of storage chips, and the target state is a state in which IO data processing is not performed;
[0133] When the SSD enters the low power consumption mode, the first storage chip is used to process IO data.
[0134] In a possible implementation, the adjustment module is used to:
[0135] determining reliability of each memory chip in the plurality of memory chips;
[0136] Determining a first memory chip from a plurality of memory chips according to the reliability of each memory chip;
[0137] The data is adjusted into the first memory chip.
[0138] In this way, determining the storage chip used for processing data based on the reliability of the storage chip can improve the efficiency of processing IO data and reduce the power consumption of the SSD.
[0139] In a possible implementation, the SSD includes multiple packages, each of the multiple packages includes at least one storage chip, and the adjustment module is used to:
[0140] Calculate the service life of each package, which is the average of the remaining service life of all memory chips in the package;
[0141] According to the service life of each package, a first package is determined from multiple packages, and the memory chip in the first package is the first memory chip.
[0142] In this way, the efficiency of processing IO data can be improved, and at the same time, the power consumption of the SSD can be reduced.
[0143] In a possible implementation, the adjustment module is used to determine the reliability of the storage chip according to the number of errors of the storage chip or the number of bit error recovery of the storage chip.
[0144] In this way, by determining the reliability of the storage chip, a storage chip with higher reliability is selected to process IO data, which can improve the efficiency of processing IO data and reduce the power consumption of the SSD.
[0145] In a possible implementation, the adjustment module is used to stop supplying power to all memory chips in a second package, where the second package is a package among multiple packages except the first package, the memory chip in the second package is a second memory chip, and the first package is the package where the first memory chip is located.
[0146] In a possible implementation, the target state includes a standby state or a power-off state.
[0147] In a possible implementation, the target parameter includes at least one of the following items: the bandwidth of the SSD in a continuous time, the amount of data in the SSD, and the number of read and write operations performed by the SSD per second in a continuous time.
[0148] By monitoring the amount of data processed by the SSD, the timing when the SSD needs to enter the low power mode is determined. The SSD entering the low power mode includes adjusting all the data cached in the SSD to the first storage chip to reduce the number of storage chips used to process data, and all second storage chips except the first storage chip enter a state of not processing IO data, and only process IO data through the first storage chip. In this way, the number of storage chips that process IO data is reduced, thereby reducing the power consumption of the SSD.
