[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] In a first aspect, an embodiment of the present application provides a method for managing power consumption of a solid state drive.

[0039] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the solid state drive power consumption management method of the present application. Figure 1 As shown, the solid state drive power consumption management method includes:

[0040] Step S10, obtaining a required read / write rate according to the amount of data sequentially read and written to the solid state drive per unit time;

[0041] In this embodiment, by real-time monitoring of the read and write operations on the solid state drive, if the read and write addresses are continuous, it is determined to be sequential read and write, and then the amount of data sequentially read and written per unit time is further determined, wherein the unit time is set according to actual needs, for example, set to 1s. Assuming that the amount of data sequentially read and written within 1s is 100, the required read and write rate is 100 / s.

[0042] Step S20, determining the number M of storage chips that need to be started per unit time according to the required read / write rate and the standard read / write rate of a single storage chip in the solid state drive;

[0043] In this embodiment, the solid-state drive includes multiple storage chips, and the standard read and write rates of each storage chip are the same and fixed, which can be determined according to the chip manual. For example, the standard read and write rate of each storage chip is 64 / s. In order to meet the read and write requirements, it is necessary to ensure that the sum of the standard read and write rates provided by the activated storage chips is greater than or equal to the required read and write rate.

[0044] For example, if the standard read / write rate of each memory chip is 64 / s and the required read / write rate is 100 / s, at least two memory chips need to be started, that is, the number of memory chips that need to be started per unit time is M=2.

[0045] Furthermore, in one embodiment, step S20 includes:

[0046] Determine the minimum integer M from the possible integers of P, where P*S'≥S, S' is the standard read and write rate of a single storage chip in the solid-state drive, and S is the required read and write rate; M is the number of storage chips that need to be started per unit time.

[0047] In this embodiment, the standard read / write rate of each memory chip is recorded as S', and multiple intervals are pre-set, such as (0, S'], (S', 2S'], (2S', 3S'], etc. Assuming that the required read / write rate S falls within the interval (0, S'], then M=1; if the required read / write rate S falls within the interval (S', 2S'], then M=2, and so on.

[0048] Furthermore, the ratio of the required read / write rate S to the standard read / write rate, which is recorded as S', can be calculated, and then the comparison value can be rounded up, and the rounded-up result can be used as M.

[0049] Step S30, starting M storage chips in the solid state drive within a unit time for sequential reading and writing.

[0050] In this embodiment, according to the required read and write rate and the standard read and write rate of a single memory chip in the solid state drive, a corresponding number of memory chips are started as needed for sequential reading and writing.

[0051] It should be noted that the above-mentioned embodiment is used for processing in each unit time, thereby ensuring that in each unit time, a corresponding number of storage chips are started on demand based on the required read and write rate and the standard read and write rate of a single storage chip in the solid-state drive, thereby balancing the read and write requirements and the SSD power consumption.

[0052] In the embodiment of the present application, the required read / write rate is obtained according to the amount of data sequentially read and written to the solid-state hard disk in a unit time; the number of storage chips M that need to be started in a unit time is determined according to the required read / write rate and the standard read / write rate of a single storage chip in the solid-state hard disk; and the M storage chips in the solid-state hard disk are started in a unit time for sequential reading and writing. Through the embodiment of the present application, according to the actual read / write performance requirements, the corresponding number of storage chips are started on demand, so that the power consumption of the solid-state hard disk is matched with the actual performance requirements, and energy waste is reduced.

[0053] Furthermore, in one embodiment, after step S10, the method further includes:

[0054] Check whether the required read / write rate is less than the total read / write rate of the SSD;

[0055] If it is less than, the step of determining the number M of storage chips that need to be started per unit time according to the required read / write rate and the standard read / write rate of a single storage chip in the solid state drive is performed.

[0056] In this embodiment, it is assumed that the solid-state drive includes N memory chips, and the standard read and write rate of each memory chip is recorded as S', then the total read and write rate of the solid-state drive = N*S'. If the required read and write rate S is less than the total read and write rate N*S' of the solid-state drive, it means that it is not necessary to start all N memory chips, and it is necessary to determine the number of memory chips M that need to be started, and start M memory chips as needed, that is, execute steps S20 and S30.

[0057] Furthermore, in one embodiment, after detecting whether the required read / write rate is less than the total read / write rate of the solid state drive, the method further includes:

[0058] If it is not less than, all storage chips in the solid state drive are started within the unit time for sequential reading and writing.

[0059] In this embodiment, if the required read / write rate S is not less than the total read / write rate N*S' of the solid state drive, it means that the read / write demand per unit time exceeds the performance of the solid state drive. In order to ensure the read / write efficiency, all storage chips in the solid state drive are started per unit time.

[0060] In a second aspect, an embodiment of the present application also provides a solid state drive power consumption management device.

[0063] A second determination module 20 is used to determine the number M of storage chips that need to be started per unit time according to the required read / write rate and the standard read / write rate of a single storage chip in the solid state drive;

[0064] The startup module 30 is used to start the M storage chips in the solid state drive within a unit time for sequential reading and writing.

[0065] Furthermore, in one embodiment, the solid state drive power consumption management device further includes a detection module, which is used to:

[0066] Check whether the required read / write rate is less than the total read / write rate of the SSD;

[0067] If it is less than, the second determination module is notified to execute the step of determining the number M of storage chips that need to be started per unit time according to the required read / write rate and the standard read / write rate of a single storage chip in the solid state drive.

[0068] Furthermore, in one embodiment, the startup module 30 is further used to:

[0069] If it is not less than, all storage chips in the solid state drive are started within the unit time for sequential reading and writing.

[0070] Further, in one embodiment, the second determining module 20 is specifically configured to:

[0071] Determine the minimum integer M from the possible integers of P, where P*S'≥S, S' is the standard read / write rate of a single storage chip in the solid-state drive, and S is the required read / write rate;

[0072] M is the number of storage chips that need to be started per unit time.
