[0031] When the fluctuation parameter of the plug-in is greater than the fluctuation preset value or the power feeding parameter of the plug-in is less than the power feeding preset value, determining that the matching response category of the corresponding plug-in for the power slot is a medium response category;

[0032] When the plug-in fluctuation parameter is greater than the fluctuation preset value and the plug-in power feeding parameter is less than the power feeding preset value, it is determined that the matching response category of the corresponding plug-in for the power slot is a weak response category.

[0033] Further, determining the number of power supply interfaces of the power supply slot corresponding to the single plug-in according to the matching response category of the single plug-in includes:

[0034] If the matching response category corresponding to a single plug-in is a strong response category, the number of power supply interfaces of a single power slot corresponding to the plug-in is within a first preset range.

[0035] Further, determining the number of power supply interfaces of a single power slot corresponding to each plug-in according to the matching response category of the single plug-in also includes:

[0036] If the matching response category corresponding to a single plug-in is a medium response category, the number of power supply interfaces of a single power slot corresponding to the plug-in is within a second preset range;

[0037] The second preset range includes the first preset range, and the second preset range is larger than the first preset range.

[0038] Further, the step of determining the number of power supply slots includes,

[0039] Determine the number of plug-ins in the strong response category, the number of plug-ins in the medium response category, and the number of plug-ins in the weak response category;

[0044] Wherein, the power supply slot includes a first power supply slot, a second power supply slot and a third power supply slot;

[0045] The condition for adding the third power slot is that the sum of the number of power supply interfaces in the first power slot and the second power slot that are not connected to plug-ins is less than the number of plug-ins of the weak response category.

[0046] Further, the step of determining the arrangement of the strong response category plug-in and each power supply interface in the first power supply slot includes:

[0047] Arrange all the plug-ins of a single strong response category in descending order of plug-in feeding parameters to form corresponding sequential strong response category plug-ins;

[0048] Dividing the sequential strong response category plug-ins into a plurality of strong response category plug-in groups;

[0049] Sequentially connect the plug-ins in each strong response category plug-in group to the power supply interface of the corresponding first power supply slot;

[0050] The number of plug-ins in each of the strong response category plug-in groups is equal to the number of the first power supply slots, and the plug-ins in each of the matching response category plug-in groups are not in the same power supply slot.

[0051] Furthermore, the arrangement of the weak response category and the power supply interface is determined according to whether the condition for adding the third power supply slot is met.

[0053] Furthermore, by determining the matching response category of each plug-in for the power slot according to the plug-in fluctuation parameter and the plug-in feeding parameter, refined management of the server power supply system can be achieved; when the fluctuation parameter of the plug-in is within an acceptable range (less than or equal to the fluctuation preset value) and the feeding parameter reaches or exceeds the feeding preset value, the plug-in is classified as a strong response category, which means that their demand for power is stable and high, and therefore more reliable power support is required; on the contrary, when the fluctuation parameter of the plug-in exceeds the fluctuation preset value and the feeding parameter is lower than the feeding preset value, the plug-in is classified as a weak response category, which indicates that its demand for power is low or fluctuates greatly, and may not require the same level of power supply guarantee.

[0062] See also Figure 1 As shown, it is a flow chart of an assembly method of a high-density power supply backplane according to an embodiment of the present invention. The present invention provides an assembly method of a high-density power supply backplane, comprising:

[0063] Step S1, obtaining historical plug-in data in the server, plug-in update data of each plug-in, plug-in usage data of each plug-in and the number of slots of the power supply backplane in the server;

[0064] Step S2, determining a plug-in fluctuation parameter of a corresponding plug-in according to the historical plug-in data and the plug-in update data of a single plug-in, and calculating a plug-in feeding parameter of a corresponding plug-in according to the plug-in usage data of a single plug-in;

[0065] Step S3, determining a matching response category of each plug-in for the power slot according to the plug-in fluctuation parameter and the plug-in feeding parameter;

[0066] Step S4, determining the number of power supply interfaces of the power slot corresponding to the single plug-in according to the matching response category of the single plug-in, and determining the number of the first power slot, the number of the second power slot and the number of the third power slot respectively in combination with the number of plug-ins corresponding to each matching response category, so as to determine the number of power slots in the slots of the power supply backplane; it can be understood that the number of power slots in the slots of the power supply backplane ≥ the number of the first power slots + the number of the second power slots + the number of the third power slots, the power supply backplane also includes a backup power slot, the number of the backup power slots = the number of current power slots + the number of currently deleted plug-ins ÷ the number of power supply interfaces of the first power slot;

[0067] Step S5, determining an arrangement of the strong response category plug-ins and each power supply interface in the first power supply slot according to the number of strong response category plug-ins, the plug-in feeding parameters of each plug-in and the number of the first power supply slots;

[0068] Step S6, determining the arrangement of the plug-ins of the middle response category and each power supply interface in the second power supply slot according to the number of plug-ins of the middle response category, the plug-in feeding parameters of each plug-in and the number of the second power supply slots;

[0069] Step S7, determining the arrangement of weak response categories and power supply interfaces;

[0070] The historical plug-in data includes the order in which the server installed the plug-ins, the time when each plug-in was first installed, and the total number of plug-ins corresponding to each installation time;

[0071] The plug-in update data includes the average update frequency of each plug-in, the number of updates of each plug-in, the update time of each plug-in, and the memory of each plug-in after each update;

[0072] The plug-in usage data of each plug-in includes the current power consumption, current usage frequency and current memory size of the plug-in;

[0073] Among them, the number of power supply interfaces in a single power slot is greater than or equal to a first preset value, and the first preset value is set to 2.

[0074] It should be noted that the plug-ins mentioned in this embodiment are the plug-ins on the original power supply backplane before the high-density power supply backplane is updated. The server can obtain historical plug-in data, plug-in update data of each plug-in, plug-in usage data of each plug-in and the number of slots of the power supply backplane.

[0075] It can be understood that the assembly method of the high-density power supply backplane provided by the present invention focuses on optimizing the power supply efficiency and stability of the server, and also ensures the flexibility and scalability of the server's power distribution unit (PDU); the present invention supports high-density server deployment and is suitable for environments such as data centers that have high requirements for space and energy efficiency.

[0076] See also Figure 2 As shown, it is a step diagram of determining the plug-in fluctuation parameter of a single plug-in according to an embodiment of the present invention. In step S2, the method for determining the plug-in fluctuation parameter of a single plug-in includes:

[0077] Step S21, determining a plug-in quantity matching degree according to the time of the first installation of each plug-in and the total number of plug-ins corresponding to the installation time;

[0078] It is understandable that after installing a plug-in, the plug-in may be deleted. Therefore, when installing the nth plug-in, the number of plug-ins included in the server should be less than or equal to n. Therefore, by determining the plug-in number matching degree, the change of all plug-ins in the server can be determined. The smaller the plug-in number matching degree A is, the smaller the change of plug-ins in the server is, that is, the fewer plug-ins are deleted.

[0079] Step S22, determining the plug-in update expected value of each plug-in according to the plug-in update data; the change of a single plug-in can be determined by the plug-in update expected value of a single plug-in, and the smaller the plug-in update expected value B is, the smaller the change of the single plug-in is, which means that the plug-in is more stable;

[0080] Step S23: determining the plug-in fluctuation parameter of the single plug-in according to the plug-in quantity matching degree and the plug-in update expected value.

[0081] In a specific embodiment, the plug-in fluctuation parameter is determined according to the following formula:

[0082] Gi=a×A+b×Bi,

[0083]

[0084]

[0085] Where Gi is the plugin fluctuation parameter of the ith plugin, i is 1, 2, ..., n, n is the number of different plugins currently installed, a is the plugin quantity weight, b is the plugin update weight, a + b = 1, A is the plugin quantity matching degree, Bi is the plugin update expected value of the ith plugin, ui is the total number of plugins in the server when the ith plugin is first installed (including the ith plugin, that is, ui ≥ 1, for example, when installing the third plugin, ui has values ​​of 1, 2, 3, ui = 1 means that the first plugin and the second plugin have been deleted when the third plugin is installed, ui = 2 means that the first plugin or the second plugin is deleted when the third plugin is installed, ui = 3 means that the first plugin and the second plugin are not deleted when the third plugin is installed), i is the ith plugin, Ri is the average update frequency of the ith plugin (in the implementation, the average update frequency of each plugin is converted into the number of updates per week), vi j is the memory size of the ith plugin after the jth update, and m is the number of updates of the ith plugin (when j=1, vi(j-1)=vi0, vi0 represents the memory size of the ith plugin after the first installation). It can be understood that if the ith plugin has been deleted, the calculation of the plugin is based on the data before the deletion.

[0086] It can be understood that Gi, A, and Bi are all dimensionless values ​​and are calculated without units when calculated according to the formula.

[0087] In implementation, the main factor affecting the plug-in fluctuation parameter of a single plug-in is the plug-in update expectation value of the single plug-in, and the secondary factor is the plug-in quantity matching degree; therefore, (1) a∈[0.1,0.25], a is determined by the plug-in quantity matching degree, the smaller the plug-in quantity matching degree A, the smaller the value of a, preferably a=0.15; (2) b∈[0.75,0.9], preferably b=0.85.

[0088] Specifically, in step S2, the plug-in feeding parameter of a single plug-in is calculated according to the following formula:

[0089]

[0090] Among them, Fi is the plug-in feeding parameter of the i-th plug-in, Wi is the current power consumption of the i-th plug-in, Pi is the current usage frequency of the i-th plug-in, Yi is the current memory size of the i-th plug-in, W is the current average power consumption of all plug-ins, P is the current average usage frequency of all plug-ins, Y is the current average power consumption memory size of all plug-ins, k1 is the power weight, k2 is the frequency weight, k3 is the memory weight, k1+k2+k3=1.

[0091] It can be understood that the plug-in feeding parameter Fi, power weight k1, frequency weight k2, and memory weight k3 of the i-th plug-in are all dimensionless values.

[0092] It can be understood that if the i-th plug-in has been deleted, its corresponding Wi, Pi and Yi are all equal to 0.

[0093] In implementation, The influencing factors of the plug-in power feeding parameters of a single plug-in include the current power consumption, current usage frequency and current memory size of the plug-in, among which the influence of current power consumption > the influence of current usage frequency > the influence of current memory size;

[0094] Therefore, k1∈[0.05,0.15], k2∈[0.15,0.4], k3∈[0.45,0.8];

[0095] Preferably, k1=0.1, k2=0.3, k3=0.6.

[0096] See also Figure 3 As shown, it is a step diagram of the matching response category of each plug-in for the power slot according to an embodiment of the present invention. In step S3, the matching response category of each plug-in for the power slot is determined according to the plug-in fluctuation parameter and the plug-in feeding parameter, including:

[0097] When the plug-in fluctuation parameter is less than or equal to the fluctuation preset value and the plug-in power feeding parameter is greater than or equal to the power feeding preset value, determining that the matching response category of the corresponding plug-in for the power slot is a strong response category;

[0098] When the fluctuation parameter of the plug-in is greater than the fluctuation preset value or the power feeding parameter of the plug-in is less than the power feeding preset value, determining that the matching response category of the corresponding plug-in for the power slot is a medium response category;

[0099] When the plug-in fluctuation parameter is greater than the fluctuation preset value and the plug-in power feeding parameter is less than the power feeding preset value, it is determined that the matching response category of the corresponding plug-in for the power slot is a weak response category.

[0100] It can be understood that the smaller the plug-in fluctuation parameter of a single plug-in, the less change the plug-in has, and the larger the plug-in feeding parameter of a single plug-in, the stronger the demand for the power supply interface (power supply) to ensure the normal operation of the plug-in; therefore, the response category of a single plug-in to the power supply interface is determined based on the plug-in fluctuation parameter and the plug-in feeding parameter.

[0101] In implementation, the fluctuation preset value g is calculated according to the formula, The feed preset value f is calculated according to the formula,

[0102] It can be understood that by determining the matching response category of each plug-in for the power slot based on the plug-in fluctuation parameter and the plug-in feeding parameter, it is possible to achieve refined management of the server power supply system; when the fluctuation parameter of the plug-in is within an acceptable range (less than or equal to the fluctuation preset value) and the feeding parameter reaches or exceeds the feeding preset value, the plug-in is classified as a strong response category, which means that their demand for power is stable and high, and therefore requires more reliable power support; on the contrary, when the fluctuation parameter of the plug-in exceeds the fluctuation preset value and the feeding parameter is lower than the feeding preset value, the plug-in is classified as a weak response category, which indicates that its demand for power is low or fluctuates greatly, and may not require the same level of power supply guarantee.

[0103] In implementation, after determining the matching response category of each plug-in, the number s1 of plug-ins of the strong response category, the number s2 of plug-ins of the medium response category, and the number s3 of plug-ins of the weak response category can be determined respectively.

[0104] Specifically, determining the number of power supply interfaces of the power supply slot corresponding to a single plug-in according to the matching response category of the single plug-in includes:

[0105] If the matching response category corresponding to a single plug-in is a strong response category, the number of power supply interfaces of a single power slot corresponding to the plug-in is within the first preset range, that is, the number of power supply interfaces of the first power slot is within the first preset range.

[0106] Specifically, determining the number of power supply interfaces of a single power slot corresponding to each plug-in according to the matching response category of the single plug-in also includes:

[0107] If the matching response category corresponding to a single plug-in is a medium response category, the number of power supply interfaces of a single power slot corresponding to the plug-in is within the second preset range, that is, the number of power supply interfaces of the second power slot is within the second preset range.

[0108] The second preset range includes the first preset range, and the second preset range is larger than the first preset range.

[0109] It is understandable that the number of power supply interfaces is a positive integer.

[0110] It can be understood that plug-ins in the strong response category require a strong level of power supply guarantee, plug-ins in the medium response category require a medium level of power supply guarantee, and plug-ins in the weak response category require a weak level of power supply guarantee; therefore, the first preset range should be a subset of the second preset range (the first preset range < the second preset range), that is, the first preset range = [2,4], the second preset range = [2,8]; in order to avoid low power supply efficiency and safety hazards caused by overheating of a single power slot when powering the plug-in, preferably, the number of power supply interfaces of a single power slot in the first preset range is set to 3 (the number of power supply interfaces of the first power slot is 3), and the number of power supply interfaces of a single power slot in the second preset range is set to 6 (the number of power supply interfaces of the second power slot is 6).

[0111] See also Figure 4 As shown, it is a step diagram of determining the number of power supply slots according to an embodiment of the present invention. In step S4, the step of determining the number of power supply slots includes:

[0112] Step S41, determining the number of plug-ins in the strong response category, the number of plug-ins in the medium response category, and the number of plug-ins in the weak response category;

[0113] Step S42, determining the number of second power supply slots according to the relationship between the number of the middle response category plug-ins and a second preset value;

[0114] Step S43, determining the number of first power supply slots according to the ratio of the number of plug-ins of the strong response category to the number of plug-ins of the medium response category;

[0115] Step S44, determining whether a condition for adding a third power slot is met, and determining the number of the third power slots according to the number of plug-ins of the weak response category when the condition for adding the third power slot is met;

[0116] Step S45, determining the number of power supply slots according to the sum of the number of the first power supply slots, the number of the second power supply slots and the number of the third power supply slots;

[0117] The power supply slots include a first power supply slot, a second power supply slot and a third power supply slot.

[0118] The condition for adding the third power slot is that the sum of the number of power supply interfaces in the first power slot and the second power slot that are not connected to plug-ins is less than the number of plug-ins of the weak response category.

[0119] In implementation, the second preset value is determined based on the number of power supply interfaces of a single power slot in the second preset range. Preferably, the second preset value is equal to the number of power supply interfaces of a single power slot in the second preset range; the number of second power slots h2 = the number of plug-ins in the response category ÷ the second preset value.

[0120] In implementation, the number of first power slots h1 = h2 × (s1 ÷ s2) × (the number of power supply interfaces of a single second power slot ÷ the number of strong response category plug-ins allowed to be connected to a single first power slot); the number of strong response category plug-ins allowed to be connected to a single first power slot is set to 2, that is, when the number of power supply interfaces of a single power slot in the first preset range is set to 3 (or 4), the number of power supply interfaces of the first power slot is 3 (or 4), but a single first power slot only allows the connection of 2 strong response category plug-ins.

[0121] It can be understood that when the conditions for adding a third power slot are not met, the number of third power slots = 0; when the conditions for adding the third power slot are met, the number of third power slots = (the number of power supply interfaces to which plug-ins are not connected in the first power slot + the number of power supply interfaces to which plug-ins are not connected in the second power slot - the number of plug-ins in the weak response category) ÷ the number of power supply interfaces of the third power slot; in implementation, the number of power supply interfaces of the third power slot ≥ the number of power supply interfaces of the second power slot, and preferably, the number of power supply interfaces of the third power slot = the number of power supply interfaces of the second power slot.

[0122] In implementation, if the calculated number of the first / second / third power slots is a decimal, the corresponding number of power slots is an integer rounded up (if the calculated value of the first power slot number is 2.6, then h1=3, i.e., there are 3 first power slots; if the calculated value of the second power slot number is 2.4, then h2=3, i.e., there are 3 second power slots; if the calculated value of the third power slot number is 0.6, then h3=1, i.e., there is 1 third power slot).

[0123] It can be understood that the power supply interface of the first power slot is used to connect plug-ins of the strong response category and plug-ins of the weak response category, the power supply interface of the second power slot is used to connect plug-ins of the medium response category and plug-ins of the weak response category, and the power supply interface of the third power slot is used to connect plug-ins of the weak response category.

[0124] Specifically, in step S5, the step of determining the arrangement of the strong response category plug-in and each power supply interface in the first power supply slot includes:

[0125] Step S51, arranging all the plug-ins of a single strong response category in descending order of plug-in feeding parameters to form corresponding sequential strong response category plug-ins;

[0126] Step S52, dividing the sequential strong response category plug-ins into a plurality of strong response category plug-in groups;

[0127] Step S53, sequentially connecting the plug-ins in each strong response category plug-in group to the power supply interface of the corresponding first power slot;

[0128] The number of plug-ins in each of the strong response category plug-in groups is equal to the number of the first power supply slots, and the plug-ins in each of the matching response category plug-in groups are not in the same power supply slot.

[0129] It can be understood that, in the first power supply slot, only the power supply interfaces at both ends of the slot are used to connect the strong response category plug-in.

[0130] In the implementation, in step S6, the method for determining the arrangement of the corresponding type plug-in and each power supply interface in the second power supply slot includes:

[0131] Step S61, arranging all plug-ins of a single medium response category in descending order of plug-in feeding parameters to form corresponding sequential medium response category plug-ins;

[0132] Step S62, dividing the response category plug-ins in the sequence into a plurality of response category plug-in groups;

[0133] Step S63, sequentially connecting the plug-ins in each corresponding category plug-in group to the power supply interface of the corresponding second power supply slot;

[0134] The number of plug-ins in each of the middle response category plug-in groups is equal to the number of the second power supply slots, and the plug-ins in each matching response category plug-in group are not in the same second power supply slot.

[0135] It can be understood that when the middle response category plug-in is connected to the second power slot, the power supply interfaces at both ends of the second power slot are connected first, and then connected to the middle in sequence; therefore, after the second power slot and the middle response category plug-in are connected, the plug-in feeding parameters in a single second power slot tend to be low in the middle and high on both sides.

[0136] Specifically, in step S7, the arrangement of the weak response category and the power supply interface is determined according to whether the condition for adding the third power supply slot is met, including:

[0137] Arrange all the plug-ins of a single weak response category in descending order of plug-in feeding parameters to form corresponding sequential weak response category plug-ins;

[0138] When the conditions for adding a third power slot are met, the weak response type plug-in first connects all the power supply interfaces of the third power slot, then connects the redundant interface in the second power slot, and after there is no redundant interface in the second power slot, connects the redundant interface in the first power slot;

[0139] When the condition for adding a third power supply slot is not met, the weak response type plug-in first fully connects the redundant interface in the second power supply slot, and then connects the redundant interface in the first power supply slot.

[0140] It can be understood that the minimum plug-in feeding parameter of the weak response type plug-in in the third power slot>the minimum plug-in feeding parameter of the weak response type plug-in in the second power slot>the minimum plug-in feeding parameter of the weak response type plug-in in the first power slot.

[0141] It can be understood that the redundant interface in the first power slot is a power supply interface to which the first power slot is not connected to a strong response type plug-in; the redundant interface in the second power slot is a power supply interface to which the second power slot is not connected to a medium response type plug-in.
