The embodiment of the disclosure provides a server performance adjusting method and a server capable of applying the method. The method comprises a load information acquisition phase and a performance adjustment phase. In the load information obtaining phase, network card load information of the server is obtained, and in the performance adjusting phase, the performance mode setting of the server in the boot system is adjusted on the basis of the network card load information on the premise of not interrupting the service of the server.

Fig. 1 schematically illustrates an application scenario of a server and a server performance adjustment method according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.

As shown in fig. 1, the application scenario may include a server 100, where the server 100 may be a server providing various data processing services and having various computing capabilities, the server 100 currently enters a boot system setting interface, the boot system has functions of booting an operating system of the server, ensuring normal operation of the operating system of the server, and the like, the boot system setting interface includes a processor setting menu, the processor setting menu includes a performance mode setting sub-menu, and the performance mode setting sub-menu includes three options: "normal mode", "high performance mode", and "low performance mode".

When the load of the processors of the server is different, the most adapted performance mode setting is correspondingly different, e.g. when the load is larger, the performance mode is set to "high performance mode" to support the correspondingly larger load, and when the load is smaller, the performance mode is set to "low performance mode" to reduce unnecessary power consumption. In other embodiments, the options in the performance mode setting submenu in the boot system of the server may be in various forms, and are not limited herein.

The server performance adjustment scheme provided by the embodiments of the present disclosure is applicable to scenarios in which performance mode settings in a boot system are actively adjusted without interrupting server operation based on differences in the load of the processors of the server.

Fig. 2 schematically shows a flow chart of a server performance adjustment method according to an embodiment of the present disclosure.

As shown in fig. 2, the method includes operations S201 to S202.

In operation S201, network card load information of a server is acquired.

In operation S202, the performance mode setting of the server in the boot system is adjusted during the operation of the server based on the network card load information.

It can be seen that, in the method shown in fig. 2, the performance mode setting of the server in the guidance system can be directly adjusted according to the network card load information of the server in the operation process of the server, and compared with the scheme in the prior art that the service of the server needs to be interrupted and the server enters the guidance system to be manually adjusted, the self-adaptive performance adjustment of the server in the operation state is realized.

It should be noted that the boot system is a system based on a hardware bottom layer of the server, and has functions of checking whether states of a processor and each controller in the server are normal, initializing a memory, a motherboard chipset, a graphics card, and a peripheral device of the server, providing basic settings of each component in the server, such as a display, a keyboard, a processor, and a memory, providing an interrupt resident program called by an operating system or an application program, starting the operating system of the boot server, and ensuring normal operation of the operating system of the server, and the like, for example, a Basic Input Output System (BIOS) is a conventional boot system, and a Unified Extensible Firmware Interface (UEFI) is a novel boot system, and the like, which are not limited herein.

In an embodiment of the present disclosure, the acquiring network card load information of the server in operation S201 includes: the network card driver reads the state statistic register group of the corresponding network card to obtain at least one of the following state information: the number of data packets received by the network card, the size of the data packets received by the network card, the speed at which the data packets are received by the network card, the number of data packets transmitted by the network card, the size of the data packets transmitted by the network card, and/or the speed at which the data packets are transmitted by the network card. And the network card driver calculates the load value of the corresponding network card based on the read at least one type of state information.

For example, the network card has a corresponding status statistics Register set (status Register), which includes registers (Packets Received [64Bytes ] Count, Packets Received [65-127Bytes ] Count, Packets Received [128-255Bytes ] Count, Packets Received [256-511Bytes ] Count, Packets Received [512-1023Bytes ] Count, Packets Received [ 1024-to-Max Bytes ] Count), registers (Total Packets Received) that record the Total amount of the network card Received Packets, registers (Packets Transmitted [64Bytes ] Count, Packets Transmitted [65-127Bytes ] Count, Packets Transmitted [ 128-511-255 Bytes ] Count, Packets Transmitted [ 128-128 Bytes ] Count, Packets Transmitted [ 128-511-255 Bytes ] Count, Packets Transmitted [1024 ] Count, Packets Transmitted [ 128-511-255 ] Count, Packets Transmitted [1024 ] Count, and the network card driver can obtain one or more state information of the corresponding network card by reading one or more registers in the state statistic register group, and because the load of the network card is related to the size, the number and the speed of the received/transmitted data packet, the load value of the corresponding network card can be accurately and conveniently obtained through the state information so as to reflect the corresponding network card load degree of the server.

In an embodiment of the present disclosure, after the network card driver obtains the load value of the corresponding network card, the method shown in fig. 2 further includes: when the load value of the network card is higher than the highest threshold value or lower than the lowest threshold value, the network card driver transmits a performance adjusting request to a boot system of the server through a pre-negotiated configuration management data table, wherein the performance adjusting request comprises information representing the expected performance mode of the network card. The expected performance mode of the network card refers to a performance mode of the processor adapted to the load value of the network card, and the highest threshold and the lowest threshold can be flexibly set according to actual requirements and are used for controlling the initiation condition of the performance adjustment request.

On this basis, the adjusting the performance mode setting of the server in the boot system during the operation of the server based on the network card load information in operation S202 includes: the boot system configures a specific register set of the processor according to the performance adjustment request to set a performance mode to a desired performance mode of the network card.

For example, after the network card driver obtains the load value of the corresponding network card, if the load value of the network card is higher than the highest threshold, which indicates that the current network card is overloaded and needs higher performance support, the network card driver transmits a performance adjustment request to the boot system of the server through the pre-negotiated configuration management data table, where the expected performance mode of the corresponding network card represented in the performance adjustment request is the "high performance mode". After acquiring the performance adjustment request, the boot system may configure a specific register set of the processor according to the performance adjustment request, so that the performance mode of the processor is set to the "high performance mode". And if the load value of the network card is lower than the lowest threshold value, which indicates that the load of the current network card is very low and the performance of the processor can be reduced for saving unnecessary energy consumption, the network card driver transmits a performance regulation request to a boot system of the server through a pre-negotiated configuration management data table, wherein the expected performance mode of the corresponding network card represented in the performance regulation request is a 'low performance mode'. After acquiring the performance adjustment request, the boot system may configure a specific register set of the processor according to the performance adjustment request, so that the performance mode of the processor is set to the "low performance mode". According to the scheme of this embodiment, the network card driver running under the operating system of the server may transmit the performance adjustment request to the boot system through a pre-negotiated configuration management data table, where the configuration management data table is a data table defined by being extended in addition to data tables of various standards and used for implementing performance adjustment related communication between the operating system and the boot system in this scheme, and the operating system transmits the performance adjustment request to the boot system by using the configuration management data table, which is very convenient and efficient.

Specifically, in an embodiment of the present disclosure, the transmitting, by the network card driver, the performance adjustment request to the boot system of the server through the pre-negotiated configuration management data table includes: the network card driver acquires a configuration management data table from a server memory, the configuration management data table is filled with identification information and expected performance modes of corresponding network cards, and a guidance system is triggered to operate through a specified interface. In some cases, the configuration management data table is already filled with the identification information of the network card corresponding to the network card driver that needs to interact after being created, so that after the network card driver acquires the configuration management data table from the server memory, the identification information of the network card does not need to be filled, and only the corresponding expected performance mode needs to be filled after the identification information of the corresponding network card. The above-mentioned bootstrap system includes according to the specific register bank of the said performance adjustment request configuration processor: and the boot system reads the configuration management data table filled by the network card driver from the server memory after being triggered, acquires corresponding performance state configuration parameters according to the expected performance mode in the configuration management data table, and writes the performance state configuration parameters into one or more corresponding specific registers.

As an optional embodiment, the identification information of the network card includes at least one of the following: vendor identification information of the network card, type identification information of the network card, and/or a serial number of the network card. And when reading the configuration management data table, the guide system distinguishes the performance adjusting requests corresponding to different network cards based on the manufacturer identification information of the network cards, the type identification information of the network cards and/or the serial numbers of the network cards in the configuration management data table.

For example, the network card driver and the boot system negotiate in advance to define a configuration management data table (OEM ACPI table) and an identifier (signature) of the configuration management data table, the configuration management data table is stored in a server memory, and a header of the configuration management data table is shown in table 1:

TABLE 1

As can be seen from table 1, the vendor identification information (vendor ID) column, the type identification information (device ID) column, the Sequence Number (SN) column, and the performance expected control flag (performance option control flag) column are included, and in other embodiments, the configuration management data table may include various extended information columns, which are not limited herein. The manufacturer identification information (vendor ID) column is used for filling identification information of a manufacturer to which the network card belongs, the type identification information (device ID) column is used for filling identification information of a device type to which the network card belongs, and the Serial Number (SN) column is used for filling a serial number of the network card, and the three kinds of identification information jointly form identification information of the network card and can globally and uniquely identify the network card. The "performance option control flag" field is used to fill in the performance mode adapted to the network card load information, and represents the performance adjustment requirement corresponding to the network card. In this example, the Performance mode setting of the boot system of the server includes three options of "high Performance mode (Max Performance)", "low Performance mode (Energy Efficiency)", and "common mode (Custom)", and the desired Performance mode of the network card may be any one of them.

The server comprises a network card A, wherein the network card A corresponds to a network card driver A ', and the network card driver A' reads a state statistical register group of the network card A at intervals of preset time and calculates a load value of the network card A. The network card driver A' compares the obtained load value with the preset highest threshold value and the preset lowest threshold value, and finds that the load value of the network card A is lower than the lowest threshold value, which indicates that the load of the network card A is small and is adapted to the lower performance mode of the server. The network card driver a' reads the configuration management data table from the server memory according to the identification identifier of the configuration management data table defined by negotiation in advance, and fills the expected performance mode "low performance mode" of the network card a in the configuration management data table, where the manufacturer identification information, the type identification information, and the serial number are already filled by the boot system when initializing the configuration management data table. The filled configuration management data table is shown in table 2 and still stored in the server memory, where the specified interface is a System Management Interrupt (SMI) interface, and the network card driver a' triggers the boot system to operate through the SMI interface.

TABLE 2

After being triggered, the bootstrap system reads the configuration management data table shown in table 2 from the server memory according to the identification mark of the configuration management data table defined by negotiation in advance, and the information in the configuration management data table reflects the following information: the performance regulation requirement of network card a, which is collectively identified by a1, a2, and A3, is "low performance mode". The method comprises the steps of leading a system to obtain pre-stored performance state configuration parameters corresponding to a low performance mode (Energy Efficiency), wherein the performance state configuration parameters can comprise frequency parameters, voltage parameters and other parameters related to the performance of a processor, and writing the performance state configuration parameters into one or more corresponding specific registers. In this example, the specific register set may be a model specific register set (MSR), the "low performance mode (Energy Efficiency)" corresponds to a smaller frequency parameter and voltage parameter, the frequency parameter and the voltage parameter corresponding to the "low performance mode (Energy Efficiency)" are written into a corresponding MSR register, the processor obtains the frequency parameter and the voltage parameter by accessing the corresponding MSR register, and adjusts the operating frequency and the operating voltage of the processor according to the frequency parameter and the voltage parameter, thereby implementing the setting of the "low performance mode (Energy Efficiency)".

In another embodiment of the disclosure, a scenario is described in which a network card driver of a plurality of network cards delivers a performance adjustment request to a boot system, and the method shown in fig. 2 further includes: and when the expected performance modes of the plurality of network cards are included in the configuration management data table and are different, the boot system sets the performance modes according to the expected performance mode of the highest level.

Following the above example, the network card driver a ' of the network card a fills the configuration management data table based on the load information of the network card a, the network card driver B ' of the network card B fills the configuration management data table based on the load information of the network card B, the network card driver C ' of the network card C fills the configuration management data table based on the load information of the network card C, and the filled configuration management data table is shown in table 3:

TABLE 3

As can be seen from table 3, the configuration management data table records a Performance adjustment request corresponding to the network card a, a Performance adjustment request corresponding to the network card B, and a Performance adjustment request corresponding to the network card C, where the network card a is identified by identification information a1, a2, and A3, the corresponding expected Performance mode is "low Performance mode" (Energy Efficiency), "the network card B is identified by identification information B1, B2, and B3, the corresponding expected Performance mode is" high Performance mode "(Max Performance)," the network card C is identified by identification information C1, C2, and C3, and the corresponding expected Performance mode is "normal mode" (Custom) ". The network card B wants to adjust the Performance mode setting to "high Performance mode (Max Performance)", which indicates that the load of the current network card B is large, and in order to ensure that each network card operates normally, the network card B should preferentially satisfy the Performance adjustment request of the network card with a large load. The boot system reads the configuration management data table shown in table 3 from the server memory, selects the expected Performance mode of the network card B for adjustment, obtains the Performance state configuration parameters corresponding to the pre-stored "high Performance mode (Max Performance)", and writes the Performance state configuration parameters into the corresponding MSR register, so that the processor accesses the MSR register to exert the corresponding high Performance.

As can be seen, the scheme of this embodiment supports the control requirements of multiple network cards in the server, processes the performance adjustment requests of the multiple network cards according to the predetermined processing rule, and when the performance adjustment requests of the multiple network cards are different, preferentially considers the requirements of the network card requiring the highest-level performance mode, thereby conforming to the actual processing situation. In other embodiments, the predetermined processing rule may be set according to specific situations, and is not limited herein.

Further, in an embodiment of the present disclosure, the configuration management data table further includes: information characterizing the current performance mode setting and an indication characterizing whether performance mode adjustment is allowed, the method shown in fig. 2 further comprising: before filling the configuration management data table, if the current performance mode setting recorded in the configuration management data table is the same as the expected performance mode, and/or if an identifier indicating that the corresponding network card is not allowed to perform performance mode adjustment is recorded in the configuration management data table, the network card driver does not transmit a performance adjustment request to the boot system any more.

For example, the header of the configuration management data table is shown in table 4:

TABLE 4

As can be seen from table 4, the configuration management data table is extended with two columns on the basis of table 1: a "current performance mode setting status flag" column and a "whether performance mode adjustment to control flag is permitted" column. The "performance option status flag" column is filled by the boot system after the previous setting, and corresponds to information of the performance mode actually configured in the specific register, and the "performance option allow to control flag" column is also filled by the boot system, and represents information of whether to allow the corresponding network card to send out a performance adjustment request.

When a network card driver needs to send a performance adjustment request of the network card, the configuration management data table shown in table 4 is read from the server memory, and the contents of the "current performance mode setting (performance option status flag)" column and the "whether performance mode adjustment (performance option allow to control flag)" column of the corresponding network card are specifically checked. If the current performance mode setting (performance option status flag) column indicates that the current performance mode setting is the same as the expected performance mode of the corresponding network card, no performance adjustment request is issued, and/or if the performance mode adjustment (performance option allow to control flag) column indicates that the performance mode adjustment of the corresponding network card is not allowed, no performance adjustment request is transmitted to the boot system. Therefore, the network card driver can be prevented from sending meaningless performance adjustment requests, the efficiency is improved, and the computing resources are saved.

Further, in an embodiment of the present disclosure, the head of the formulation management data table is as shown in table 4, and the method shown in fig. 2 further includes: after reading the configuration management data table, if the current performance mode setting recorded in the configuration management data table is the same as the expected performance mode, and/or if an identifier representing that the network card is not allowed to perform performance mode adjustment is recorded in the configuration management data table, the boot system does not adjust the performance mode setting according to the performance adjustment request of the network card.

Following the above example, after being triggered, the boot system reads the configuration management data table shown in table 4 from the server memory, and specifically checks the contents of the "current performance mode setting (performance operation status flag)" column and the "whether performance mode adjustment (performance operation allow to control flag)" column of the corresponding network card for the performance adjustment request of each network card. If the current performance mode setting (performance option status flag) column indicates that the current performance mode setting is the same as the expected performance mode of the corresponding network card, the performance adjustment request of the network card is not processed, and/or if the performance mode adjustment (performance option allow to control flag) column indicates that the performance mode adjustment of the corresponding network card is not allowed, the performance adjustment request of the network card is not processed.

And, further, in an embodiment of the present disclosure, the header of the formulation management data table is as shown in table 4, and the method shown in fig. 2 further includes: after the boot system adjusts the performance mode setting, the adjusted performance mode setting is updated to the configuration management data table, and the identifier representing whether each network card is allowed to perform performance mode adjustment is updated to the configuration management data table.

The method shown in fig. 2 is described below with reference to fig. 3A to 3B in conjunction with specific embodiments:

in this embodiment, the server includes network cards A, B and C corresponding to the network card drivers a ', B ' and C ', respectively, the boot system is a BIOS system, the network card driver and the BIOS system negotiate in advance to define an OEM ACPI table of configuration management data tables and identification identifiers thereof, a header of the OEM ACPI table is shown in table 4, and identification information corresponding to each of the network cards A, B and C is completely filled in the table.

Fig. 3A schematically shows a flow chart of a server performance adjustment method according to another embodiment of the present disclosure, describing the server performance adjustment process from the network card driver side.

As shown in fig. 3A, the method includes operations S301 to S306.

In operation S301, a load value of the network card is calculated by reading the status statistic register set of the network card, and when the load value of the network card reaches a preset threshold, operation S302 is performed.

In this operation, the load value of the network card obtained by reading the state statistics register group of the network card through calculation is described above, and is not described again. The preset threshold includes the above-mentioned highest threshold and lowest threshold, and the load value of the network card reaching the preset threshold means that the load value of the network card is higher than the highest threshold or lower than the lowest threshold. The setting Interface may be provided to the user in advance through an hii (human Interface initialization) configuration program of the server, and the user may flexibly set the threshold.

In operation S302, a corresponding configuration management data table is found according to the identification identifier of the configuration management data table defined by negotiation with the boot system in advance, and the content corresponding to the corresponding network card in the configuration management data table is found according to the identifier information of the network card.

In this operation, taking the network card a as an example, the network card driver a 'finds the OEM ACPI table according to the pre-negotiated identification identifier, and the network card driver a' matches in the OEM ACPI table according to the vendor identification information a1, the type identification information a2, and the serial number A3 of the network card a to find the row corresponding to the network card a.

In operation S303, it is checked whether the current performance mode setting corresponding to the network card is different from the expected performance mode of the network card, if so, operation S304 is performed, and if not, operation S306 is performed.

In this operation, the network card driver a' checks whether the "current performance mode setting (performance option status flag)" corresponding to the network card a in the OEM ACPI table is different from the expected performance mode of the current network card a, and there is a need to continue performance adjustment only when the two are different.

In operation S304, it is checked whether the network card allows performance mode adjustment, if yes, operation S305 is performed, and if no, operation S306 is performed.

In this operation, the network card driver a' checks whether "whether performance option allow to control flag" corresponding to the network card a in the OEM ACPI table is allowed, and only when it is allowed, it is necessary to continue performance adjustment.

In operation S305, a desired performance mode is filled, and the boot system is triggered through the SMI interface, so that the boot system performs a corresponding performance mode adjustment.

In this operation, the network card driver a' fills in an expected performance Mode (performance option control flag) adapted to a current load value of the network card a at a position of an "expected performance Mode" corresponding to the network card a in the OEM ACPI table, and after the completion of the filling, transmits a command value defined in advance to an SMI interface (SW SMI port, IO 0xB2), triggers the SW SMI interface, so that the processor enters a system management Mode (SMM Mode), and forwards to execute an SMI handler program in the BOIS system, that is, triggers the BIOS system shown in fig. 3B to execute a performance Mode adjustment operation.

In operation S306, the logic is tripped out.

Fig. 3B schematically shows a flowchart of a server performance adjustment method according to another embodiment of the present disclosure, which describes the server performance adjustment process from the boot system side.

As shown in FIG. 3B, the method includes operations S301 'to S307'.

In operation S301', each network card detected by the server motherboard is initialized, and an initial value of each position is defined in a configuration management data table defined by negotiation in advance.

In this operation, the BIOS system initializes the network cards A, B and C detected by the server motherboard, fills identification information corresponding to the network cards A, B and C into the OEM ACPI table, initializes a "performance expected mode (performance option control flag)" field and a "current performance mode setting (performance option flag)" field to default values, and initializes a "whether performance mode adjustment (performance option allow to control flag)" field to "allow".

Triggered in operation S302', performance mode adjustment is started.

In the operation, after the network card finishes filling the OEMACPI table, the SW SMI interface is triggered, and when the SW SMI interface is triggered, the SMI handler program in the BIOS system is started to be executed, namely, the performance mode adjustment is started to be executed.

In operation S303', a corresponding configuration management data table is found according to the identification of the configuration management data table defined by pre-negotiation with the boot system.

In operation S304', it is checked whether the expected performance mode corresponding to each network card is different from the current performance mode setting, and the performance adjustment request of the network card with the expected performance mode being the same as the current performance mode is not processed.

In the operation, the BIOS system checks whether a "current performance mode setting (performance option flag)" corresponding to the network card a in the OEM ACPI table is different from a "desired performance mode (performance option control flag)" of the current network card a, if so, performs subsequent operation on the performance adjustment request of the network card a, and if not, does not process the performance adjustment request of the network card a. For the same reason of the network cards B and C, no further description is given. The performance adjustment requests for network cards a and B are processed further in this example.

In operation S305', it is checked whether each network card allows performance mode adjustment, and a performance adjustment request of a network card that does not allow performance mode adjustment is not processed.

In the operation, the BIOS system checks whether "whether performance option to control flag" corresponding to the network card a in the OEM ACPI table is allowed, if so, performs subsequent operation on the performance adjustment request of the network card a, and if not, does not process the performance adjustment request of the network card a. The network card B is similar and will not be described again. In this example, network cards a and B are both allowed.

In operation S306', a target performance mode is determined according to the expected performance mode of each network card and a predetermined processing rule, a corresponding specific register meeting the requirement of the target performance mode is configured, and the configuration management data table is updated.

In this operation, the predetermined processing rule may be as follows: and if the expected performance modes corresponding to the network cards A and B are the same, taking the expected performance mode as a target performance mode, and if the expected performance modes of the network cards A and B are different, taking the expected performance mode with a higher level as the target performance mode. The BIOS system configures the MSR register group corresponding to the requirement of the target performance mode, after the configuration is completed, the column of 'current performance mode setting (performance option status flag') in the OEM ACPI table is updated to the configured target performance mode, and the content of 'whether performance mode adjustment to control flag' is allowed to be performed corresponding to each network card is updated according to the logic requirement. In this example, if the target performance mode is the expected performance mode of the network card a, the BIOS updates "whether performance mode adjustment (performance option to control flag) is allowed" corresponding to the network cards B and C to disallow.

In operation S307', the process ends.

The operation exits the SMI handler program and ends the process of the BIOS system executing the server performance adjustment.

Based on the scheme provided by each embodiment of the present disclosure, the following beneficial effects can be achieved: the method saves the manual adjustment process of the user when the performance mode of the server needs to be adjusted, avoids interrupting the service of the server, and enables the user to flexibly preset the condition for performing the performance adjustment request and support the performance adjustment requirements of a plurality of network cards.

The boot system 420 is used to adjust the performance mode settings of the server 400 in the boot system 420 during the operation of the server 400 based on the network card load information.

It can be seen that, in the operation process of the server shown in fig. 4, the performance mode setting of the server in the guidance system can be directly adjusted according to the network card load information of the server, and compared with a scheme in the prior art that the service of the server needs to be interrupted and the server enters the guidance system to be manually adjusted, the self-adaptive performance adjustment of the server in the operation state is realized.
