Detailed Description

Referring to fig. 1, a schematic structural diagram of an apparatus according to an embodiment of the present disclosure is shown, where the apparatus is composed of one or more power consumption components, and as shown in fig. 1, the apparatus 10 at least includes a power supply 101, a processor 102, and a memory 103.

The power supply 101 is configured to supply power to each power consumption component of the apparatus 10 to ensure that the power consumption component operates normally, and the power supply 101 may supply power to the memory 103 to complete data access. It should be understood that the power consumption of the memory 103 will vary with the amount of data accessed, but the maximum power consumption will not exceed the power rating of the memory 103. Alternatively, the power supply 101 may independently supply power to some of the power consuming components, such as only the memory 103.

The processor 102 is a Central Processing Unit (CPU), and may be used to perform calculation processing and the like on data.

The storage 103 is a device for storing data, and may be a memory or a hard disk. The memory is an internal memory which directly exchanges data with the processor, can read and write data at any time, is fast, and is used as a temporary data storage of an operating system or other programs in operation.

The Memory includes at least two types of Memory, for example, the Memory may be a random access Memory (ram) or a Read Only Memory (ROM). For example, the Random Access Memory may be a Dynamic Random Access Memory (DRAM) or a Storage Class Memory (SCM). Static Random Access Memory (SRAM), and the like.

The memory in this embodiment may also be a hard disk. Hard disks are typically used to store data persistently. The hard disk type is a Solid State Disk (SSD), a mechanical hard disk (HDD), or other types of hard disks. Among them, the SSD has higher performance (e.g. high read/write speed), and therefore has wider application and faster development, and at present, the SSD has at least NVME, SATA, SAS, etc. interface types.

The device 10 may be provided with one or more hard disks. Please refer to fig. 1, which is a schematic structural diagram of an apparatus 10. In another form, as shown in fig. 2, the storage system (storage array) is composed of a plurality of hard disks, which may be completely the same, may not be completely the same, and may also be completely different, and in addition, the form of the hard disk may be a standard form, and may also be a non-standard form, which is not limited in this application.

The hard disk in this embodiment may also have a memory interface, and the processor may directly access the hard disk. As shown in fig. 2, a plurality of hard disks are connected to the same splitter and connected to a cpu, and the cpu can access the hard disks. It should be understood that fig. 2 is merely an example and that the apparatus 10 may include more or fewer devices than those shown in fig. 2.

A common storage scheme is to group multiple SSDs (e.g., 25 SSDs or 36 SSDs or more) together, so as to provide a large amount of storage space for the host, and also provide other value-added services for the host, which is not described herein in detail. Taking 25 as an example, assuming that the 25 SSDs are all 2.5 inch NVME SSDs (the maximum power consumption (rated power) of the 2.5 inch NVME SSDs is 25W), if the 25 SSDs operate at full speed, the total power consumption is 25W × N, and correspondingly, the required power supply is also larger. If the situation sets the power consumption of the hard disk to be a certain value, under certain conditions, for example, when the amount of data stored in the system is large and frequent, the high performance of the hard disk cannot be exerted, and it should be understood that the SSD access data amount is realized by electric energy, and the larger the electric energy is, the larger the amount of data to be accessed at one time is.

At present, a power distribution scheme for a storage system is to forcibly set the power consumption of all SSDs at a certain fixed value according to a power supply power and the power consumption value of the SSDs, for example, for a 2.5 inch NVME SSD, the maximum power consumption is set to be 16W for operation. The existing mode can cause that the performance of the hard disk cannot be exerted, the overall performance of the storage system is influenced, and in certain understanding, the method can also be regarded as waste of resources.

In view of this, an embodiment of the present application provides a dynamic power consumption adjustment method, in which an operation parameter of the system is monitored, the system is composed of a plurality of electronic devices, the operation parameter is used to indicate a total power consumption of the system, and a set power consumption corresponding to each of some or all power consumption devices of the at least one power consumption device is determined according to the operation parameter of the system; and configuring the maximum operation power consumption of each power consumption device as the determined set power consumption of the power consumption device. In the above manner, during the operation process, the operation parameter of the system is changed, and the set power of the power consumption device in the first system is adjusted according to the operation parameter, so as to dynamically adjust the maximum operation power consumption of the power consumption device, thereby bringing the performance of the power consumption device into full play as much as possible.

The technology of the present application is described in detail below with reference to the accompanying drawings.

Referring to fig. 3, a power dynamic adjustment method provided for the embodiment of the present application may be applied to the apparatus shown in fig. 2, and as shown in fig. 3, the method may include the following steps:

step 301: and acquiring an operation parameter value of an operation parameter of the system.

The system may be the storage system shown in fig. 2, or may be a system formed by a plurality of other electronic devices in the apparatus 10, where the electronic devices in the same system may be the same type of electronic devices, for example, all the electronic devices in the system are SSDs, or different types of electronic devices, for example, the system includes SSDs and memories, which is not limited in this embodiment of the present application.

The electronic device is operated based on electric energy, where the operation parameter may be used to indicate a total operation power consumption of a plurality of electronic devices in the system, for example, the operation parameter may be the total operation power consumption, or the operation parameter may be a parameter capable of reflecting the total operation power consumption of the system, for example, a performance parameter of the system, it should be understood that the electronic device has the highest performance when operating based on a rated power consumption, and there is an association relationship between the performance of the electronic device and the power consumption, therefore, the total performance of the system may also be monitored to determine the total power consumption of the system, and of course, the total operation power consumption may also be indicated by other parameters, which is not limited in the embodiment of the present application.

Step 302: and determining the maximum operation power value of each of at least part of the electronic equipment in the plurality of electronic equipment according to the acquired operation parameter values.

The method for determining the maximum operation power value of the electronic equipment in the system according to the operation parameter value in the embodiment of the application has various modes: two are exemplarily listed below:

the first method is as follows: and inquiring the preset corresponding relation according to the preset corresponding relation between the operation parameter value and the maximum operation power value of the system to determine the maximum operation power value corresponding to the obtained operation parameter value.

As shown in table 1 below, a specific example of a preset corresponding relationship is provided in the embodiments of the present application.

TABLE 1

Actual total operating power consumption of the system	Maximum operating power value
		(0，30％]A	First set value
(30％，50％]A	The second set value
		(50％，70％]A	Third set value
…	…

In table 1, a represents the maximum operating power consumption in the system, that is, the total operating power of the system when each electronic device in the system operates at the maximum operating power, which is also the maximum total operating power of the system. Where, illustratively, first set value > second set value > third set value, and so on.

As can be understood from table 1, when the total operating power of the system is not greater than 30% of the maximum total operating power of the system, the maximum operating power value of each electronic device of the system is a first set value; when the total operating power of the system is more than 30% of the maximum total operating power of the system and less than 50% of the maximum total operating power of the system, the maximum operating power of each electronic device of the system is a second set value; and so on.

It should be noted that table 1 is only an example given for convenience of description, where the total operating power consumption of the system may be determined according to the obtained operating parameter value, alternatively, table 1 may also represent a corresponding relationship between an actual operating parameter value of the system and the maximum operating power value, and this is not limited in this embodiment of the present application.

In an alternative embodiment, the maximum operation power value of part of the electronic devices in the system can be adjusted. See table 2 below for a specific example of another preset correspondence provided in the embodiments of the present application.

TABLE 2

Actual total operating power consumption of the system	Maximum operating power value
		(0，30％]A	First setting, n-n 1
(30％，50％]A	Second setting, n-n 2
		(50％，70％]A	Third setting, n-n 3
…	…

In table 2 a still indicates the maximum operating power consumption in the system, and illustratively, the first set value > the second set value > the third set value, and so on. Hereinafter, the same reference numerals are used for the same meaning, and the description will not be repeated. n represents the number of electronic devices in the system that need to be power regulated. Wherein n1, n2 and n3 are all positive integers and are all smaller than the number of all electronic devices in the system.

For example, when the total operation power of the system is not more than 30% of the maximum total operation power of the system, adjusting the maximum operation power value of n1 electronic devices in the system to be a first set value; when the total operating power of the system is more than 30% of the maximum total operating power of the system and less than 50% of the maximum total operating power of the system, adjusting the maximum operating power values of the n2 pieces of electronic equipment in the system to be a second set value; and so on. Where n2 ≧ n1, the n2 electronic devices that are adjusted may include the n1 electronic devices that are adjusted entirely, or include the n1 electronic devices that are adjusted entirely, or include the n1 electronic devices that are adjusted entirely. In addition, the n electronic devices to be adjusted may be randomly selected or may be selected according to the priority order of the electronic devices, for example, the electronic devices are ranked according to priority, and the electronic device with the lower priority is selected first.

The method and the device can sacrifice the performance of the electronic equipment with low priority to ensure that the electronic equipment with high priority exerts the maximum performance as much as possible. When the total operation function of the system is higher, the maximum operation power value of the electronic equipment with lower priority is reduced firstly, and the maximum operation power value of the electronic equipment with higher priority is reduced finally.

As shown in table 3 below, a specific example of yet another preset corresponding relationship is provided in the embodiments of the present application. In table 3, it is assumed that the system includes a first electronic device and a second electronic device, wherein the first electronic device has a higher priority than the second electronic device.

TABLE 3

Actual total operating power consumption of the system	Maximum operating power value
		(0，30％]A	The first electronic device is a first set value, and the second electronic device is a fourth set value
(30％，50％]A	The first electronic device is a first set value, and the second electronic device is a fifth set value
		(50％，70％]A	First electricityThe sub-device is the second set value, and the second electronic device is the sixth set value
…	…

For example, the first setting value is greater than (>) the second setting value > the fourth setting value > the fifth setting value > the sixth setting value, and it should be noted that the setting values listed in table 3 are only examples and do not limit the relationship between the setting values of the first electronic device and the second electronic device.

In table 3, when the total operating power of the system is not greater than 30% of the maximum total operating power of the system, the maximum operating power value of the first electronic device in the system is set to the first set value, and the maximum operating power value of the second electronic device is set to the fourth set value; when the total operating power of the system is greater than 30% of the maximum total operating power of the system and less than 50% of the maximum total operating power of the system, keeping the maximum operating power value of the first electronic device unchanged, and setting the maximum operating power value of the second electronic device as a fifth set value; when the total operating power of the system is greater than 50% of the maximum total operating power of the system and less than 70% of the maximum total operating power of the system, setting the maximum operating power value of the first electronic device as a second set value, and setting the maximum operating power value of the second electronic device as a sixth set value; and so on.

It should be understood that, in this embodiment of the present application, an initial maximum operating power value of each electronic device in the system may also be set, and if the initial maximum operating power value of the electronic device is the same as the maximum operating power value of the electronic device corresponding to the obtained operating parameter value, no adjustment is needed, for example, in table 3, if the initial maximum operating power value of the first electronic device is the first set value, and if the obtained operating parameter value indicates that the total operating power consumption of the system is (0, 30% ] a, the maximum operating power value of the first electronic device does not need to be changed, of course, the initial maximum operating power value of the electronic device may not be subjected to the apparatus in this embodiment, which is not limited in this embodiment, in addition, table 3 is illustrated with two electronic devices with different priorities, and actually there may be a plurality of electronic devices with different priorities included in the system in this embodiment, correspondingly, the preset corresponding relationship may also define adjustment manners of maximum operating power values of a plurality of electronic devices with different priorities, which is not limited in the embodiment of the present application.

The preset correspondences may also be combined with each other in the present application, for example, please refer to table 4, which is a specific example of another preset corresponding relation provided in the embodiment of the present application.

TABLE 4

Wherein n4, n5, n6, n7, n8 and n9 are all positive integers, n4, n6 and n8 are smaller than the number of first electronic devices included in the system, and n5, n7 and n9 are smaller than the number of second electronic devices included in the system.

As can be understood from table 4, when the total operating power of the system is not greater than 30% of the maximum total operating power of the system, the maximum operating power value of n4 first electronic devices in the system is set (or maintained) as the first set value, and the maximum operating power value of n5 second electronic devices is set (or maintained) as the fourth set value; when the total operating power of the system is more than 30% of the maximum total operating power of the system and less than 50% of the maximum total operating power of the system, setting (or keeping) the maximum operating power value of at least n6 first electronic devices unchanged, and setting (or keeping) the maximum operating power value of at least n7 second electronic devices unchanged; and so on.

The numerical values listed in tables 1 to 4 are examples, and the examples of the present application do not limit the values.

The following describes an example of a power dynamic adjustment method provided in the embodiments of the present application with reference to specific embodiments. For convenience of description, the technical solution of the present application is described below by taking a storage system as an example.

Referring to fig. 4, the apparatus includes a processor, a splitter, a storage system, a power supply, and a power supply monitoring unit, wherein the storage system includes a plurality of hard disks. The power supply is used for independently supplying power to the storage system, and the power supply monitoring unit can monitor the output power of the power supply, which is understood to be the total operating power of the storage system.

If the power supply can meet the condition that all the hard disks in the storage system work at the maximum operating power (rated power), the maximum operating power value of the hard disks does not need to be adjusted, and any hard disk can be kept to work at the maximum operating power so as to obtain the maximum hard disk performance.

If the power supply can not meet the condition that all the hard disks in the storage system work at the maximum operating power, the maximum operating power of the hard disks can be adjusted in the above mode.

Illustratively, in the storage system, part of the plurality of hard disks are used for cache use and part of the plurality of hard disks are used for persistent data storage, and the hard disks used for cache use are given higher priority than the hard disks used for persistent data storage. For convenience of description, a hard disk used for cache may be referred to as a cache disk, and a hard disk used for persistent data storage may be referred to as a data disk.

Taking the above-mentioned manner as an example, the preset corresponding relationship of the storage system may be as shown in table 5 below, and in table 5, the maximum operation power value of each hard disk is taken as an example of 25W.

TABLE 5

Power supply output power consumption/total power consumption	Maximum operating power value
		≤50％	The Cache disk is 25W, and the data disk is 16W
50％＜，≤70％	The Cache disk is 25W, and the data disk is 12W
		70％＜，≤80％	The Cache disk is 20W, and the data disk is 10W
80％＜	The Cache disk is 16W, and the data disk is 8W

Based on the preset corresponding relationship, the process of adjusting the power value of the storage system comprises the following steps:

step 1: acquiring an operation parameter value of an operation parameter of a storage system;

the operation parameter value can be the total operation power consumption of the storage system, namely the output power consumption of the power supply, and the output power consumption value is acquired by the power supply monitoring module; the total power consumption of the power supply is known and fixed.

Step 2: according to a preset corresponding relation (for example, table 5), determining a maximum operation power value of each of at least some of the plurality of electronic devices of the storage system corresponding to the operation parameter value.

For example: if the output power consumption of the power supply is less than 50% of the total power consumption of the power supply, the maximum operation power value of the data disk can be set to be 16W without adjusting the maximum operation power value of the cache disk; if the output power consumption of the power supply is more than 50% of the total power consumption of the power supply and not more than 70% of the total power consumption of the power supply, the maximum operation power value of the cache disk can still be set to 12W without adjusting the maximum operation power value of the cache disk; if the output power consumption of the power supply is more than 70% of the total power consumption of the power supply and not more than 80% of the total power consumption of the power supply, setting the maximum operation power value of the cache disk to be 20W, and setting the maximum operation power value of the data disk to be 10W; and so on.

It should be understood that table 5 is only an example and does not constitute a limitation to the storage system, and any parameter satisfying an actual scenario is applicable to the embodiment of the present application. In addition, the above table 5 may also be expressed by total power consumption for operation of the memory system/total power consumption for maximum operation of the memory system, for example, the power output power consumption/total power consumption for power supply may be replaced by total power consumption for operation of the memory system (power output function)/total power consumption for maximum operation of the memory system. Or may be identified by replacing the operating parameter values, which is not limited in the embodiments of the present application.

Referring to fig. 5, the apparatus includes a processor, a splitter, a storage system and a performance monitoring unit, wherein the storage system includes a plurality of hard disks. The performance monitoring unit is capable of monitoring performance parameters of the storage system.

If the power supply can meet the requirement that all the hard disks in the storage system work at the maximum performance (for example, work at rated power), the maximum operation power value of the hard disks does not need to be adjusted, and any hard disk can be kept to exert the maximum performance.

If the power supply can not meet the condition that all hard disks in the storage system work at the maximum performance, the maximum operation power of the hard disks can be adjusted in the above mode.

It is also exemplified below that the storage system shown in fig. 5 comprises at least a cache disk and a data disk.

When the storage system is powered on, firstly, the performance test is carried out on different hard disks of the storage system, and the performance parameters of the system when each hard disk in the system reaches the maximum operation power are recorded. For example, when each hard disk in the system operates at the maximum operating power, the performance parameter of the system is a, each hard disk in the system operates at 50% of the maximum operating power, the performance parameter of the system is b, each hard disk in the system operates at 70% of the maximum operating power, the performance parameter of the system is c, each hard disk in the system operates at 80% of the maximum operating power, and the performance parameter of the system is d, then the above table 5 may also be represented as the following table 6.

TABLE 6

Performance parameter	Maximum operating power value
		≤a	The Cache disk is 25W, and the data disk is 16W
a＜，≤b	The Cache disk is 25W, and the data disk is 12W
		b＜，≤c	The Cache disk is 20W, and the data disk is 10W
c＜	The Cache disk is 16W, and the data disk is 8W

step 1: acquiring a total performance parameter value of a total performance parameter of the storage system;

the value of the overall performance parameter may be collected by the performance monitoring module.

Step 2: according to a preset corresponding relation (for example, table 6), determining a maximum operation power value of each of at least some of the plurality of electronic devices of the storage system corresponding to the operation parameter value.

For example: if the total performance parameter value of the system is not larger than a, the maximum operation power value of the cache disk can be set to be 16W without adjusting the maximum operation power value of the data disk; if the total performance parameter value of the system is larger than a and not larger than b, the maximum operation power value of the cache disk can still not be adjusted, and the maximum operation power value of the data disk is set to be 12W; if the total performance parameter value of the system is larger than b and not larger than c, setting the maximum operation power value of the cache disk to be 20W, and setting the maximum operation power value of the data disk to be 10W; and so on.

It should be understood that table 6 is only an example and does not constitute a limitation to the storage system, and any parameter satisfying an actual scenario is applicable to the embodiment of the present application. In addition, the above table 5 may also be expressed by total power consumption for operation of the memory system/total power consumption for maximum operation of the memory system, for example, the power output power consumption/total power consumption for power supply may be replaced by total power consumption for operation of the memory system (power output function)/total power consumption for maximum operation of the memory system. Or may be identified by replacing the operating parameter values, which is not limited in the embodiments of the present application. Of course, the preset corresponding relationship is a semi-static adjustment manner, and in the embodiment of the present application, the maximum operation power value may also be determined by quantizing parameters in the preset corresponding relationship into a formula, so that each different total operation power consumption corresponds to a different set maximum operation power value, which is not limited in the embodiment of the present application.

For example, determining a maximum operation power value corresponding to the obtained operation parameter value according to the first parameter value, the first operation power value and the obtained operation parameter value; illustratively, the maximum operating power value satisfies the following equation 1 or equation 2:

pmax ═ max (P1V/V1, Pnominal) equation 1

Wherein Max () represents taking the maximum value within (); pmax represents the set maximum operating power value; v1 represents a first parameter value; p1 represents the corresponding maximum operation power value when the operation parameter value is V1; v represents the acquired operation parameter value of the system; the ptrade represents the maximum operating power value of the electronic device itself.

Pmax_nKn x [ max (P1 XV/V1, P rating)]Equation 2

Pmax_nIndicating a set maximum operating power value for electronic device n, Kn being a coefficient for electronic device n, which may be determined based on the priority of the electronic device.

For example, when the total performance parameter value of the system is a, the maximum operating power value corresponding to the electronic device is 16w, and when the total performance parameter value of the system is e, the maximum operating power value corresponding to the electronic device is 16 × e/a.
