Technical Field
[0001] The present invention relates to the technical field of solid state drives, and in particular to a method, device and computer equipment for dynamically balancing power consumption and performance of SSDs. Background Art
[0002] As a new type of storage medium, SSD solid state drive uses NAND particles as data storage. Compared with traditional HDD, its biggest advantage is high read and write performance. As the read and write performance is getting higher and higher, the power consumption is also getting higher and higher. The host is very sensitive to the power consumption and performance of SSD. Therefore, the firmware algorithm must balance the performance and power consumption of SSD as much as possible.
[0003] Generally, SSD controllers do not care about power consumption for the sake of performance, while some SSD controllers limit the peak performance of SSD controllers for the sake of power consumption data. Such an approach cannot take into account both performance and power consumption, and the competitiveness of SSD controllers will be greatly weakened. Summary of the invention

[0006] Receive read and write request commands, record the data volume of each read and write request command, and accumulate the data volume of the read and write request commands;
[0007] Compare the data volume of the read / write request command with a preset threshold value to obtain a data volume comparison result;
[0008] If the data volume comparison result is that the data volume of the read / write request command is greater than the preset threshold within the preset time, calling a preset first timing to process the read / write request command, wherein the timing period of the first timing is greater than the timing period of the standard timing;
[0009] If the data volume comparison result is that the data volume of the read / write request command is less than the preset threshold, the preset second timing is called to process the read / write request command, and the timing period of the second timing is equal to the timing period of the standard timing.
[0010] Further, the data volume of the read / write request command is compared with a preset threshold value, and the data volume comparison result obtained includes:
[0011] The data volume of the read and write request commands accumulated within a preset time interval is compared with a preset threshold value to obtain a data volume comparison result within the preset time interval.
[0012] Furthermore, the timing period of the first timing is the timing period of the standard timing plus the first delay time.
[0013] Furthermore, the timing cycle of the standard timing is the processing time of each read / write request command.
[0014] The present invention also provides a device for dynamically balancing SSD power consumption and performance, comprising:

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.
[0032] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.
[0033] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.
[0034] The first embodiment of the present invention is: a method for dynamically balancing SSD power consumption and performance, comprising the following steps:
[0035] S10, receiving a read / write request command, recording the data volume of each read / write request command, and accumulating the data volume of the read / write request commands.
[0036] In this embodiment, the SSD records each read and write request command in chronological order, and accumulates the data volume of the newly received read and write request commands in sequence.
[0037] S20: Compare the data volume of the read / write request command with a preset threshold value to obtain a data volume comparison result.
[0038] In a specific embodiment, step S20 specifically includes: comparing the data volume of the read and write request commands accumulated within a preset time interval with a preset threshold value to obtain a data volume comparison result within the preset time interval.
[0039] In this embodiment, it is possible to determine whether the data volume of the read / write request command received within 1 second is greater than 96KB at a time interval of one second. If it is greater than 96KB, a data volume comparison result indicating a large data volume is obtained.
[0040] S30. If the data volume comparison result is that the data volume of the read / write request command is greater than a preset threshold within a preset time, a preset first timing is called to process the read / write request command, wherein the timing period of the first timing is greater than the timing period of the standard timing.
[0041] The timing period of the first timing is the timing period of the standard timing plus the first delay time, and the timing period of the standard timing is the processing time of each read / write request command.
[0042] In this embodiment, if the data volume of the received read / write request command is too large, the read / write timing is set to the first timing, the read / write is delayed, and the performance of the controller is limited to reduce power consumption. For example: after processing a read / write request command, a delay of 4 microseconds is performed before processing the next read / write command request.
[0043] S40. If the data volume comparison result is that the data volume of the read / write request command is less than the preset threshold, call a preset second timing sequence to process the read / write request command, wherein the timing period of the second timing sequence is equal to the timing period of the standard timing sequence.
[0044] In this embodiment, if the data volume of the received read / write request command is too small, the read / write timing is set to the second timing, and the read / write timing is not delayed. The peak performance of the SSD controller is used. For example, after processing one read / write request command, the next read / write command request is processed immediately.
[0045] The beneficial effects of this embodiment are: by identifying the scenario, the read and write performance of the SSD is dynamically adjusted to balance the power consumption. For scenarios with a large number of read and write requests, a slow timing is set to limit the performance of the SSD controller to reduce power consumption; for scenarios with a small number of read and write requests, a fast timing is set, that is, peak performance is used, to achieve a balance between performance and power consumption, thereby improving the competitiveness of the SSD controller.
[0046] like Figure 2 As shown, an embodiment of the present invention further provides a device for dynamically balancing SSD power consumption and performance, including:
[0047] The data volume statistics module 10 is used to receive read / write request commands, record the data volume of each read / write request command, and accumulate the data volume of the read / write request commands.
[0048] The data volume comparison module 20 is used to compare the data volume of the read / write request command with a preset threshold value to obtain a data volume comparison result.
[0049] The data volume comparison module 20 is specifically used to compare the data volume of the read and write request commands accumulated within a preset time interval with a preset threshold value to obtain a data volume comparison result within the preset time interval.
[0050] The first read / write calling module 30 is used to call a preset first timing to process the read / write request command if the data volume comparison result is that the data volume of the read / write request command is greater than a preset threshold within a preset time, and the timing period of the first timing is greater than the timing period of the standard timing.
[0051] The timing period of the first timing is the timing period of the standard timing plus the first delay time, and the timing period of the standard timing is the processing time of each read / write request command.
[0052] The second read / write calling module 40 is used to call a preset second timing to process the read / write request command if the data amount comparison result shows that the data amount of the read / write request command is less than a preset threshold, and the timing period of the second timing is equal to the timing period of the standard timing.
