Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1, a flowchart illustrating steps of a method for adjusting power consumption of a network card according to an embodiment of the present application is shown, where the method includes:

Step 101, obtaining historical flow information of a network port in a first preset time period.

In the embodiment of the application, in the actual working state of the network card, the network card is always in a state of continuously existing data flow, but in most of the working time of the network card, the data flow of the network card is less than 10% of the actual bandwidth of the network card, even more often less than 1% of the actual bandwidth, and only very individual time is more than 10%, so that when the existing scene does not have a large amount of data increase, the network card continuously operates in a full power consumption mode, and a large amount of energy is consumed, thereby causing resource waste. In order to reduce the power consumption of a network card, the application discloses a method for reducing the power consumption of the network card without depending on an idle mode of a server system.

Specifically, the network card in the present application may be a network card applied to a server, which is a network card with PCIe (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCI bus) interfaces, and PCIe-based expansion cards can be inserted into PCIe slots in a device motherboard such as a host, a server, and a network switch, where PCIe network cards can implement a series of point-to-point connections through the switch to control data flow. After the PCIe network card is inserted, a logical connection is formed between the slot and the network card so as to communicate with each other. A server may include a plurality of slots to which a plurality of network cards are installed. The historical flow information of the network port in the first preset time period can be obtained for each network card, so that the working state of each network card can be independently adjusted.

Further, the first preset time period may be a time period before the current time, for example, the first preset time period may be a time of one week before the current time, and for one network card, the historical traffic information in the previous period may be obtained. For example, in order to adjust the working state of the network card in the week, the historical flow information of the network card in the week may be obtained first, where the historical flow information includes the flow values of each time point, and the maximum flow value, the minimum flow value and the average flow value of each sub-time period. Each time point may be a time point when the flow value is sampled, for example, taking updating the network port flow value once per minute as an example, each time point may correspond to each minute of the previous week, the flow value at each time point may be a flow value corresponding to each minute, and each sub-time period may be a custom period, for example, if the sub-time period is one hour, the maximum flow value, the minimum flow value and the average flow value corresponding to the sub-time period, that is, the maximum flow value, the minimum flow value and the average flow value corresponding to a certain hour.

For example, if the first preset time period is a week, the first minute flow value is counted as 20Mb/s, the second minute Zhong Liu is counted as 40Mb/s, the flow value of each minute is counted sequentially, 60 minutes is counted as a sub-time period, a minimum flow value of 20Mb/s, a maximum flow value of 70Mb/s and an average flow value of 40Mb/s in the sub-time period are obtained, then the information of the first hour is used as a reference, a mathematical statistical model is established, the data is classified and counted, then the information of the second hour is counted based on the mathematical statistical model, according to 7x24 hours of a week, the maximum data flow value and the minimum data flow value of each day and the distribution condition of the average data flow value of the next week can be counted, and further the data flow of the next week can be predicted.

And 102, determining a required flow threshold value in a second preset time period according to the historical flow information.

In the embodiment of the present invention, the maximum flow value in the second preset time period may be determined according to the historical flow information, where the second preset time period may be the current week, for example, the first preset time period is the flow statistics of the previous week, and then the second preset time period may be the current week, and through the flow statistics of the previous week, the possible demand flow threshold of the current week may be predicted.

Further, the demand flow threshold may be used to characterize a peak value of the current peripheral flow value, and according to the demand flow threshold, data such as an operating bandwidth required by the network port to meet the demand flow threshold may be determined.

Specifically, the manner of determining the demand flow threshold value in the second preset time period according to the historical flow information may be: if it is determined that the maximum flow value is the maximum value in the whole first preset time period on the sunday according to the historical flow information of the first preset period, the maximum flow value of a certain sub-time period on the sunday can be used as the predicted required flow threshold corresponding to the second preset time period. Still alternatively, an average of the maximum flow values for each sub-period of the day may be calculated, and a maximum of the average of the maximum flow values may be selected as the demand flow threshold for the second preset time period. It should be noted that, the sampling time interval of the network port flow, the division of the sub-time period and the determination of the required flow threshold in the second preset time period may be determined according to the actual requirement, which is not limited in the embodiment of the present application.

And step 103, determining configuration information of the network card according to the required flow threshold.

In the embodiment of the application, the configuration information of the network card can be determined according to the required flow threshold, and the configuration information of the network card is used for configuring the working state of the network card, so that the network card can meet the data transmission requirement in a second preset time period. In the actual running process of the network card, the network card defaults to be in a state of full power consumption running, and the actual bandwidth occupied by the network card in operation only occupies a small part of the theoretical bandwidth.

Specifically, after the required flow threshold is determined, the configuration information of the network card can be determined by taking the required flow threshold as a reference, and the network card can meet the data transmission requirement of each day in the whole second preset time period by taking the required flow threshold as a reference.

Further, if the cumulative maximum value of the current week data reaches M1 in the period from T1 to T2, the network card estimates Mx (maximum flow in a unit time) as a required flow threshold of the network port, and the network card can adjust its own transmission rate and PCIE bandwidth to reduce power consumption by calculating the connection condition of PCIE links of the network card and satisfying the required flow threshold. The calculated target transmission rate and target PCIE bandwidth can be used as configuration information of the network card.

Step 104, adjusting the working state of the network card based on the configuration information; the working state comprises the following steps: the working frequency of the network card and the link width between the network card and the host end.

In the embodiment of the invention, after the configuration information of the network card is determined based on the demand flow threshold, the working state of the network card can be adjusted based on the configuration information. For example, if the configuration information indicates that the transmission rate of the network card is GEN2 and the link width is PCIE ex1, the bandwidth rate requirement of the required traffic threshold may be met, and then the transmission rate of the network card and the PCIE link width may be adjusted based on the configuration information. The host side may be a server.

Further, the network card adjusts the working frequency of the internal network card through calculation of the data flow through the statistical model, reduces the main frequency of part of internal processors under the condition that the requirement of a required flow threshold can be met, synchronously adjusts links of the network card and a server, for example, can close redundant PCIE TX and RX differential signals for configuration of a network card chip default PCIEX8, only retains a pair of differential signals, namely retains PCIEX1, for detection of the network card and the server host, and forcibly configures Gen3 rate of the network card chip default to Gen2, so that the network card can negotiate with the server by using a PCIEX1 Gen2 mode, and the aim of reducing the overall power consumption of the network card is achieved.

In summary, in the embodiment of the application, historical flow information of a network port in a first preset time period is obtained; determining a required flow threshold value in a second preset time period according to the historical flow information; determining configuration information of the network card according to the required flow threshold; adjusting the working state of the network card based on the configuration information; the working state comprises the following steps: the operating frequency of the network card and the link width between the network card and the server. The method acquires the historical flow information of the network card, evaluates the required flow threshold value of a second preset time period according to the historical flow information, determines the configuration information corresponding to the requirement of the network card meeting the required flow threshold value based on the required flow threshold value, and adjusts the working state of the network card based on the configuration information.

Referring to fig. 2, a flowchart illustrating steps of another method for adjusting power consumption of a network card according to an embodiment of the present application is shown, where the method includes:

step 201, obtaining historical flow information of a network port in a first preset time period;

this step can refer to step 101, and will not be described here.

Step 202, determining a flow gain coefficient according to the target historical flow information corresponding to the second preset time period.

In the embodiment of the application, in order to make the determined required flow threshold more accurate, the application can also determine the flow gain coefficient first, wherein the flow gain coefficient is used for increasing the gain flow value on the basis of the maximum flow value so as to ensure that the working state of the network card after adjustment can meet the actual requirement in a second preset time period and ensure the fluency of data transmission in the second preset time period.

Specifically, the flow gain factor may be a value greater than 1, and the determined maximum flow value may be multiplied by the flow gain factor to obtain the final demand flow threshold. The flow gain coefficient may be determined by calculating the target historical flow information corresponding to the second preset time period, or may be determined by user-defining based on the actual requirement, which is not limited in the embodiment of the present application. The second preset time period may be a time period to be predicted, and the target historical flow information corresponding to the second preset time period may be historical flow information associated with a flow value of the second preset time period. For example, the second preset time period is the current week, then the target historical traffic information corresponding to the second preset time period may be the historical traffic information of the previous week, and if the second preset time period is the current week day, then the target historical traffic information corresponding to the second preset time period may be the historical traffic information of the current week day, if it is determined based on the historical flow information that the maximum value or the average value of the data flow always occurs on the day of the week, then if the second preset time period is the present week, the target historical flow information corresponding to the second preset time period may be the historical flow information of the day of the week. The embodiments of the present application are not limited herein. The use of the flow gain coefficient can enable the network card to still meet the actual data transmission requirement and ensure the working stability of the network card if sudden data increase exists in a second preset time period.

Optionally, step 202 includes:

Sub-step 2021, determining a target maximum flow value, a target minimum flow value and a target average flow value in the second preset time period according to the flow values of each target time point corresponding to the second preset time period;

sub-step 2022, determining a flow gain factor based on the target maximum flow value, the target minimum flow value, and the target average flow value.

In the embodiment of the present invention, for the sub-step 2041 and the sub-step 2042, if the second preset time period is the present week, the flow value of each target time point corresponding to the second preset time period may be the flow value of each time point of the previous week corresponding to the time point of the present week. If the second preset time period is the current week day, the flow value of each target time point corresponding to the second preset time period may be the flow value of each time point of the previous week day. Taking the second preset time period as the current week day as an example, according to statistics of flow values of all time points of the previous week day, a target maximum flow value, a target minimum flow value and a target average flow value predicted by the current week day can be determined. Or the second preset time period is taken as an example of the tenth sub-time period of Zhou Zhouri, and according to statistics on the flow value of the tenth sub-time period of the last week and day, the target maximum flow value, the target minimum flow value and the target average flow value corresponding to the tenth sub-time period of the week and day can be predicted and determined.

The flow gain coefficient may be determined from the target maximum flow value, the target minimum flow value, and the target average flow value.

Step 203, determining a required flow threshold in unit time according to the flow gain coefficient, the accumulated maximum flow corresponding to the second preset time period, and the time length of the second preset time period; and the accumulated maximum flow is accumulated and determined through the flow values of all target time points corresponding to the second preset time period.

In the embodiment of the invention, the required flow threshold value in unit time can be calculated by the following model:

Mx=（M1/（T2-T1））×（1+Mc/（Ma+Mb））

Where Mx represents the demand flow threshold, ma represents the flow maximum, mb represents the flow maximum and Mc represents the flow average, (T2-T1) represents the predicted second preset time period. The calculation result of (1+mc/(ma+mb) may be used as the flow gain coefficient, and the constant 1 may be a specified gain adjustment parameter, or may be another numerical value.

Specifically, if the cumulative maximum flow of the current week data reaches M1 in the period from T1 to T2, the network card estimates Mx as a maximum flow of the network port, and the network card can adjust the Gen3 rate and the bandwidth of PCIEX8 according to the flow requirement by calculating the connection condition of the PCIE link of the network card, thereby reducing the rate and the bandwidth of the network card as much as possible while meeting the flow requirement. For example, if M1 is 2400, T2-T1 is 60 minutes, ma represents the maximum flow value in the 60 minutes, such as 50 Mb/s, mb represents the minimum flow value in the 60 minutes, such as 20 Mb/s, mc represents the average flow value in the 60 minutes, such as 40 Mb/s, then the required flow threshold in the 60 minutes is calculated as: 62.8 Mb/s. At this time, 62.8 Mb/s may be used as the demand flow rate threshold per unit time.

And 204, determining configuration information of the network card according to the required flow threshold.

This step can refer to step 103, and will not be described here.

Optionally, step 204 includes:

Sub-step 2041, determining a target bandwidth rate required by the network card according to the required flow threshold;

Sub-step 2042, determining a target operating frequency and a target link width of the network card based on the target bandwidth rate.

In the embodiment of the present invention, for sub-step 2041 and sub-step 2042, after the required flow threshold is determined, the working state that the network card needs to reach, that is, the target bandwidth rate that the network card needs to meet, may be determined based on the required flow threshold, and the target bandwidth rate may be the network card bandwidth rate that meets the required flow threshold, and the target working frequency and the target link width of the network card may be correspondingly adjusted based on the target bandwidth rate, so that the network card after the configuration is adjusted, while meeting the requirement of the required flow threshold, the power consumption of the network card is reduced.

Step 205, adjusting the working state of the network card based on the configuration information; the working state comprises the following steps: the operating frequency of the network card and the link width between the network card and the server.

This step can refer to step 104, and will not be described here.

Optionally, step 205 specifically includes:

Sub-step 2051, adjusting the working frequency of the network card to the target working frequency, and adjusting the link width between the network card and the server to the target link width.

In the embodiment of the invention, PCIE (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, peripheral component interconnect express protocol) is a high-speed bus for connecting various components and external devices on a motherboard, so that the data transmission rate can be improved to an extremely high level, and different PCIE versions have a certain difference. The data transmission bandwidth of PCIE Gen1 is 2.5Gbps, each channel supports unidirectional 250MB/s data transmission, the data transmission bandwidth of PCIE Gen2 is 5Gbps, each channel can support unidirectional 500MB/s data transmission, the data transmission bandwidth of PCIE Gen3 is 8Gbps, each channel can support unidirectional 1GB/s data transmission, PCIE Gen4 can raise the data transmission rate to 16Gbps, each channel can support unidirectional 2GB/s data transmission, and along with continuous raising of PCIE version, the data transmission rate of each channel is also continuously raised, and data transmission can be completed more quickly. Meanwhile, the power consumption of PCIE equipment is increased to a certain extent. Therefore, after the required flow threshold is determined, a transmission rate protocol meeting the required flow threshold can be determined, if the default transmission rate of the network card is the Gen3 rate and the Gen2 is determined to meet the data transmission requirement based on the required flow threshold, the default transmission rate of the network card chip can be forcedly configured from the Gen3 rate to the Gen2, so that the power consumption is reduced to a certain extent by adjusting the working frequency of the network card.

Further, in PCIe systems, physical connections between two PCIe devices are made with links (links), each of which interconnects the two devices point-to-point. One link corresponds to a bus to which only one device is attached, and each link is assigned a link number. A link includes a plurality of paths, and the number of selectable paths is: x1, x2, x4, x8, x12, x16 or x32. Each channel is provided with four signal lines, each signal direction is provided with a pair of differential signals, and data can be simultaneously transmitted or received, so that double simplex and serial differential data transmission between two devices is realized. Therefore, after the required flow threshold is determined, the number of paths meeting the required flow threshold, that is, the link width, can be determined, for example, the configuration of the default link width pci ex8 of the network card chip can be configured by closing redundant PCIE TX and RX differential signals, and only one pair of differential signals, that is, the PCIE ex1, is reserved for the PCIE TX and RX to be used for communication between the network card and the host end of the server, so as to achieve the purpose of reducing the power consumption of the network card.

Optionally, the substep 2051 specifically includes:

sub-step 20511, switching the default transmission rate protocol corresponding to the network card to a target transmission rate protocol; the transmission rate defined by the target transmission rate protocol is smaller than the transmission rate defined by the default transmission rate protocol;

and step 20512, closing an idle transceiving pair channel between the network card and the server based on the target link width.

In an embodiment of the present invention, after the required traffic threshold is determined for sub-step 20511 and sub-step 20512, a transmission rate protocol satisfying the required traffic threshold may be determined as the target transmission rate protocol. For example, if the default transmission rate of the network card is the Gen3 rate, and it is determined that the data transmission requirement can be met by using the Gen2 based on the requirement flow threshold, the default transmission rate of the network card chip can be forcedly configured from the Gen3 rate to the Gen2, so as to reduce the power consumption to a certain extent by adjusting the working frequency of the network card.

Likewise, after the required traffic threshold is determined, the link width meeting the required traffic threshold can be determined, for example, the configuration of the default link width pci ex8 of the network card chip can be used for communication between the network card and the host end of the server by closing redundant PCIE TX and RX differential signals, and only one pair of differential signals are reserved for PCIE TX and RX, namely, PCIE ex1 is reserved, and PCIE ex1 is the target link width, so that the purpose of reducing the power consumption of the network card is achieved.

Optionally, step 205 specifically includes:

A substep 2052, based on a communication link between the network card and the host, of sending a renegotiation signal to the host;

sub-step 2053, adjusting the working state of the network card based on the configuration information when the host releases the resources corresponding to the network card based on the renegotiation signal.

In the embodiment of the present application, for sub-step 2052 and sub-step 2053, after determining the configuration information of the network card, the network card may be reconfigured based on the configuration information, so that the power consumption is reduced when the network card operates in a new period. Specifically, the network card firmware informs the server host of the need of renegotiating the PCIE at the slot position of the network card through the PCIE link, at this time, the BIOS (Basic Input Output System ) at the server host starts to release resources of the network card, after the resources are released, the network card firmware starts to adjust the configuration of its own chip, the network card adjusts the frequency of the internal operation of the network card based on the calculation result of the required flow threshold, and under the condition that the requirement of the data flow can be met, the main frequency of part of internal processors is reduced, the link of the network card and the server host is adjusted synchronously, for example, the configuration of the network card chip default PCIE ex8 can be used for negotiating with the server by closing redundant PCIE TX and RX differential signals, only one pair of differential signals is reserved for PCIE ex1, which is used for communication between the network card and the server host, and the Gen3 rate of the network card default Gen2 is forcedly configured to Gen2, so that the power consumption of the network card default Gen 1 and Gen2 can be used, and the overall negotiation of the network card is reduced. For one data center, a large number of servers are operated, and after the method provided by the application is adopted to reduce the power consumption of each network card, the total reduction amount of the power consumption of the network card is considerable, and the overall power consumption of the data center can be effectively reduced.

In the embodiment of the present application, for step 206 and step 207, since the network card reconfiguration needs to be performed after the network card is restarted, the data transmission needs to be suspended during the network card reconfiguration, and the data transmission process is continued after waiting for the network card reconfiguration to be completed. Therefore, in order to prevent the network card configuration process from affecting the normal operation of the server to the greatest extent, the application can also select a time period with the minimum network port data flow rate to perform the network card reconfiguration process based on the statistical result of the flow data of each sub-time period in the first preset time period.

For example, based on the flow value of each time point included in the first preset time period and information such as the maximum flow value, the minimum flow value and the average flow value of each sub-time period, a sub-time period with the minimum flow value can be determined, for example, a time period with the minimum flow value corresponding to each sub-time period is used as a time period for adjusting the working state of the network card. Or the time period with the minimum average flow value corresponding to each sub-time period is used as the time period for adjusting the working state of the network card, and the embodiment of the application is not limited herein.

In the embodiment of the present invention, referring to fig. 3, with respect to step 208 and step 209, based on the distribution situation of the maximum value in the graph, a time period corresponding to the maximum flow value may be correspondingly determined, and when the demand flow threshold of the next time period is predicted based on the historical flow information of the first preset time period, a second target time period with the maximum flow value may be determined based on the distribution situation of the maximum flow value of each sub-time period of the first preset time period; the second target time period is taken as a time period for evaluating the demand flow threshold.

If it is determined based on historical traffic information that the maximum or average of data traffic is always present on weekdays, then the demand traffic threshold determined based on the weekday data traffic information may cover bandwidth demands for other time periods within the week. Therefore, if the second preset time period is the present week, the target historical flow information corresponding to the second preset time period may be the historical flow information of the week of the previous week, and the required flow threshold of the present week is evaluated based on the historical flow information area of the week, so as to ensure that the configuration information of the network card determined based on the required flow threshold can meet the actual data transmission requirement.

Optionally, the method further comprises:

In the embodiment of the present application, based on step 210 and step 211, after the working state of the network card is reconfigured based on the updated configuration information, after the configuration information of the network card is continuously collected and changed, the data flow value of the network port at each time point in the new time period is determined, the maximum flow value, the minimum flow value and the average flow value of each sub-time period are determined, and based on the collected data, the required flow threshold of the next period is continuously predicted, so as to determine the configuration information corresponding to the network card in the next time period, thereby reducing the power consumption of the network card in the next time period. The application can acquire the data flow information of the network card in real time, and further continuously and intelligently adjust the working state of the network card, so that the adjustment of the power consumption of the network card is independent of the idle power saving mode of the system, the automatic adjustment of the power consumption of the network card based on the actual flow condition of the network card is realized, and the overall power consumption of the server is reduced.
