Background

In a blade server, a BMC (Baseboard Manager Controller, baseboard management controller) on a motherboard node communicates with a CMM (CHASSIS MANAGEMENT Module ) on a management board via an IPMB (INTELLIGENT PLATFORM MANAGEMENT BUS ). In the communication process, the BMC is mainly responsible for collecting data, and the collected data can comprise power on-off data, energy consumption data, FRU (FIELD REPLACE Unit, field replaceable Unit) data, sensor information and the like, and the CMM is mainly responsible for displaying the data.

The traditional communication mode between the BMC and the CMM is completed through a mode of periodically inquiring by the CMM, namely, the CMM continuously sends an inquiry command to the BMC according to a fixed period, after the BMC receives the inquiry command, the BMC processes all data acquired at the current moment according to the inquiry command, and all the processed data are returned to the CMM through an IPMB bus.

However, the large amount of data transfer between the conventional BMC and CMM results in a busy IPMB bus, which in turn results in a long data transfer duration and inefficient communication.

Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

First, before the technical scheme of the embodiment of the present application is specifically described, a description is first given of a technical background or a technical evolution context on which the embodiment of the present application is based. In general, in the technical field of server data transmission, the current technical background is: the BMC (Baseboard Manager Controller, baseboard management controller) on the main board collects server parameter data according to a preset period, and then the CMM (CHASSIS MANAGEMENT Module ) sends a query request to the BMC according to a periodic query mode to obtain the server parameter data collected in the current period of the BMC. However, when the BMC and the CMM perform full data transmission, the IPMB bus for transmission is busy, and thus, the duration of data transmission is long, and communication efficiency is not high. Based on the background, the applicant discovers that when all server parameters are transmitted between the BMC and the CMM through long-term model simulation research and development and collection, demonstration and verification of experimental data, the problems of busy IPMB bus and low transmission efficiency can occur due to huge data volume of all server parameters, so how to solve the problem of low transmission efficiency between the BMC and the CMM becomes a current urgent problem to be solved. In addition, in the present application, the data volume of all server parameters between the BMC and the CMM is found to be huge, and the technical problem that the IPMB bus is busy and the technical scheme described in the following embodiments are caused, and a great amount of creative labor is applied by the applicant.

In one embodiment, as shown in fig. 1, a data transmission method is provided, and this embodiment is illustrated by applying the method to a blade server. In this embodiment, the method includes the steps of:

Step 101, a transmission communication list is acquired.

The transmission communication list comprises transmission data of at least one transmission parameter, a transmission check value corresponding to the transmission data and a transmission priority corresponding to the transmission parameter. For example, table 1 below shows:

TABLE 1

Table 1 contains transmission data corresponding to the n transmission parameters, transmission check values (CRC, cyclic Redundancy Check, cyclic redundancy check), and corresponding priorities. Where there may be a parallel priority in the transmission communication list, e.g. data 2 and data 3 each correspond to priority 1.

In an implementation, a BMC node on a blade server motherboard may obtain a transmission communication list pre-stored by the blade server. Specifically, the record of one transmission parameter included in the transmission communication list may be: sensor temperature, 25 ℃, transmit check value 3, priority 3. Meanwhile, the transmission data in the transmission communication list is updated, and when the transmission in the transmission communication list is updated, the corresponding transmission check value and the transmission priority are required to be updated.

Step 102, a query request sent by a data requester is received.

The query request carries a reference check value corresponding to transmission data of each transmission parameter stored in the data requester CMM. The reference check value is calculated by the transmission data sent by the BMC which is received and stored last time by the CMM. Each reference check value is represented by 32-bit (bit) data, the reference check value of the 32-bit being much smaller than the amount of transmission carrying the transmission data.

In implementation, since the transmission data of the transmission parameters collected by the BMC node is continuously updated, in order to maintain consistency with the transmission data of the transmission parameters of the BMC node, the CMM in the blade server may send a query request to the BMC in a preset period, and the BMC node receives the query request and reads the reference check value carried in the query request. The reference check value is used to identify whether the transmission data of each transmission parameter in the BMC is updated.

And step 103, determining updated target transmission data by comparing the transmission check value corresponding to the transmission data with the received reference check value according to the transmission priority sequence corresponding to each transmission parameter in the transmission communication list, and sending the target transmission data and the transmission check value corresponding to the target transmission data to the data requesting party.

In implementation, the BMC node reads the transmission data of the transmission parameter 1 with the highest transmission priority (i.e. the transmission priority 1) and the transmission check value 1 corresponding to the transmission data first according to the transmission priority sequence corresponding to each transmission parameter in the transmission communication list, for example, the transmission priority 1 is higher than the transmission priority 2, the transmission priority 2 is higher than the transmission priority 3, and so on, and then the BMC node compares the transmission check value 1 corresponding to the transmission data 1 with the received reference check value 1 of the transmission parameter 1, if the transmission check value 1 is inconsistent with the reference check value 1, determines that the transmission data of the transmission parameter 1 is updated, and further determines the updated transmission data as the target transmission data. After determining the target transmission data, the BMC node may send the target transmission data and a transmission check value corresponding to the target transmission data to the data requester CMM.

Optionally, after receiving the target transmission data and the transmission check value corresponding to the target transmission data, the CMM verifies according to the transmission check value corresponding to the target transmission data, so as to ensure that the target transmission data is not tampered in the transmission process. And then, the CMM updates the local storage by using the target transmission data and the transmission check value of the target transmission data so as to ensure the consistency of the transmission data of each transmission parameter in the CMM and the BMC node. The transmission check value of the transmission data of each transmission parameter updated by the CMM can be used as a reference check value carried when the CMM initiates the query request next time.

In the data transmission method, the BMC node acquires a transmission communication list; based on the transmission priority order corresponding to each transmission parameter in the transmission communication list; and sequentially comparing the transmission check values corresponding to the transmission parameters in the transmission communication list with the reference check values carried in the received query request, determining the updated target transmission data in the transmission communication list, and sending the target transmission data and the transmission check values corresponding to the target transmission data to the data requesting party. By adopting the method, the data identification is carried out according to the order of the transmission priority in the transmission communication list, so that the data which is frequently updated is firstly identified, and meanwhile, only the changed data is sent to the data receiver, thereby reducing the transmission data quantity, saving the transmission time and improving the transmission efficiency.

In one embodiment, as shown in FIG. 2, prior to step 103, the method further comprises the steps of:

Step 201, monitor transmission data of each transmission parameter.

In implementations, the transmission parameters of the blade server include: fan speed, alarm information, power consumption data, log data, sensor information, health status information, firmware version information, asset information, network information, etc., embodiments of the present application are not limited. And the BMC node monitors the transmission data of each transmission parameter of the blade server according to a preset period, and identifies the transmission data after the transmission parameters are updated.

Step 202, if it is monitored that the transmission data of the first transmission parameter is updated, calculating a transmission check value of the transmission data updated by the first transmission parameter, updating the transmission check value of the transmission data updated to the transmission communication list, and adding a candidate transmission identifier for the first transmission parameter.

In an implementation, if the BMC node monitors that the transmission data of the first transmission parameter is updated, a transmission check value of the transmission data after the update of the first transmission parameter is calculated. The way to calculate the transmission check value may be: for the numerical value type transmission data, specific field characteristic information contained in the transmission data is utilized to calculate, and for the state information type transmission data, the field characteristic information contained in the transmission data and the current time information can be utilized to calculate a transmission check value corresponding to the transmission data together, so that the embodiment of the application is not limited as to how to calculate the transmission check value of the transmission data. And then, the BMC node updates the transmission data updated by the first transmission parameter and the corresponding transmission check value into the transmission communication list, and adds a candidate transmission identification for the first transmission parameter. The candidate transmission identity is used to characterize the transmission data of the first transmission parameter.

In an alternative embodiment, as shown in fig. 3, the processing manner in step 103 may further include, based on the BMC initially identifying that the transmission data of the first transmission parameter is updated and adding the candidate transmission identifier, the following steps:

in step 301, in the transmission communication list, a transmission parameter to which a candidate transmission identifier is added is identified as a candidate transmission parameter.

In the implementation, the BMC node performs initial identification screening on the transmission parameters in the transmission communication list, that is, uses the transmission parameters with the candidate transmission identifiers as the candidate transmission parameters, and obtains an initial screening result. For example, among all the transmission parameters included in the transmission communication list, the transmission parameter 1, the transmission parameter 3 and the transmission parameter 5 to which the candidate transmission identifier is added are identified, and the transmission parameter 1, the transmission parameter 3 and the transmission parameter 5 are used as candidate transmission parameters, so as to obtain an initial screening result including the transmission parameter 1, the transmission parameter 3 and the transmission parameter 5.

Step 302, according to the transmission priority order corresponding to the candidate transmission parameters in the transmission communication list, comparing the transmission check value corresponding to the transmission data of the candidate transmission parameters with the received reference check value, determining the updated target transmission data, and sending the target transmission data and the transmission check value corresponding to the target transmission data to the data requester.

In the implementation, the BMC node takes the screened candidate transmission parameters as a new screening range, sequentially compares the transmission check values corresponding to the transmission data of each candidate transmission parameter with the received reference check values according to the transmission priority sequence corresponding to each candidate transmission parameter, and finally determines the updated target transmission data. And then, the BMC sends the target transmission data determined in the candidate transmission parameters and the transmission check value corresponding to the target transmission data to the data requester CMM.

In this embodiment, the BMC node monitors the transmission data of the transmission parameters, identifies the update of the transmission data, and adds a candidate transmission identifier to the transmission parameters corresponding to the transmission data identified as updated as candidate transmission parameters, so as to implement preliminary screening of the transmission parameters, and further enable the BMC node to identify, after receiving the query request, the update of the transmission data in the candidate transmission parameters that are preliminarily screened, further according to the transmission check value, so as to obtain a screening result of the transmission data that is finally updated. By adding the candidate transmission identification to the transmission data which is identified to be updated, the verification value identification range after the BMC receives the query request is shortened, a mode of directly comparing the transmission verification values of the whole transmission data is replaced, the time for identifying the updated data is shortened, and the data transmission efficiency is improved.

In one embodiment, when it is monitored in step 202 that the transmission data is updated, a transmission check value of the updated transmission data is calculated, and as shown in fig. 4, the method further includes:

Step 401, if it is monitored that the transmission data of the first transmission parameter is updated, updating the number of times of updating the transmission data of the first transmission parameter in the first preset period.

In implementation, the first preset period is a unit time, for example, a unit time may be 10 seconds, 1 minute, 10 minutes, etc., which is not limited in the embodiment of the present application. Meanwhile, the first preset period is recursively updated according to a unit time shorter than the period duration of the first preset period, for example, the period duration of the first preset period is 10 seconds, and then the period recursion rule of the first preset period is as follows: according to the recurrence rule of the first preset period, if the BMC node monitors that the transmission data of the first transmission parameter in the transmission communication list is updated, the BMC node reckons the number of times of updating the transmission data of the first transmission parameter in the first preset period corresponding to the current time, and then updates the updated number of times of updating the transmission data of the first transmission parameter in the first preset period to the updated number of times record in the transmission communication list.

Step 402, determining transmission priorities corresponding to the transmission parameters according to the updated transmission data updating times of the first transmission parameters and the transmission data updating times of other transmission parameters in the first preset period, and updating the determined transmission priorities corresponding to the transmission parameters to the transmission communication list.

In the implementation, the BMC node sorts the transmission data updating times from large to small according to the updated transmission data updating times of the first transmission parameters and the transmission data updating times of other transmission parameters in the same first preset period to obtain a sorting result of the transmission data updating times, and further determines the transmission priority corresponding to each transmission parameter according to the sorting result of the transmission data updating times. That is, it is determined that the transmission data update times ranking result is the first transmission parameter, and its transmission priority is also the first. The update determination process of the transmission priority will be described in detail later, and will not be described in detail here.

In this embodiment, when the transmission data of each transmission parameter is updated, the transmission priority of each transmission parameter is updated by sorting the number of times of updating the transmission data of each transmission parameter from large to small in the same first preset period where the transmission data of each transmission parameter is updated, so as to realize updating of active transmission parameters in the transmission communication list, and the method has higher transmission priority and can be identified and transmitted earlier.

In one embodiment, as shown in fig. 5, in step 402, according to the updated number of times of updating the transmission data of the first transmission parameter and the updated number of times of updating the transmission data of other transmission parameters in the first preset period, determining the transmission priority corresponding to each transmission parameter, a processing procedure may include the following steps:

Step 501, sorting the updated number of times of transmission data update of the first transmission parameter and the number of times of transmission data update of other transmission parameters in a first preset period from large to small, to obtain a sorting result of the number of times of transmission data update of each transmission parameter.

In implementation, the BMC node performs the sorting from large to small on the updated transmission data update times of the first transmission parameter and the transmission data update times of other transmission parameters in the same first preset period, so as to obtain a transmission data update times sorting result of each transmission parameter, as shown in table 2 below, and the transmission data update times sorting result of each transmission parameter in the transmission communication list is shown in table 2 below.

TABLE 2

Step 502, determining transmission priorities corresponding to the transmission parameters according to the sorting result.

In implementation, the order included in the ordering result is descending order of the number of times of updating the transmission data from large to small, and according to the order, the BMC node determines the transmission priorities of the transmission parameters corresponding to the transmission data to be the same order, for example, the number of times of updating the transmission data of the transmission parameter 1 ranks the 2 nd bit in the number of times of updating the transmission data of each transmission parameter, and then the transmission priority of the corresponding transmission parameter 1 is the priority 2, that is, the transmission priority is also ranked in the 2 nd bit.

In an alternative embodiment, as shown in fig. 6, in step 402, according to the updated number of times of updating the transmission data of the first transmission parameter and the number of times of updating the transmission data of other transmission parameters in the first preset period, determining the transmission priority corresponding to each transmission parameter, a processing procedure may include the following steps:

Step 601, obtaining the data type of each transmission parameter.

In implementation, after a period of transmission data update, the BMC node may determine a data type of the transmission parameter according to a number of transmission data updates of each transmission parameter in the period of time, and then the BMC node may obtain the data type determined by each transmission parameter in the transmission communication list. The data types may include a static data type and a dynamic data type, where the data types are used to characterize transmission data activity of the transmission parameters. In addition, the method for determining the data type of the transmission parameter by the BMC node will be described in detail later, and will not be described here again.

Step 602, determining transmission priorities corresponding to the transmission parameters according to the updated transmission data update times of the first transmission parameters, the transmission data update times of other transmission parameters in the first preset period, and the data types of the transmission parameters.

In an implementation, after the BMC node obtains the data types of each transmission parameter in the transmission communication list, the BMC node may classify the transmission parameters according to different data types, as shown in fig. 7, divide all the transmission parameters in the transmission communication list into transmission parameters of a static data type and transmission parameters of a dynamic data type according to different data types, and determine, for each transmission parameter of the data types, transmission priorities corresponding to each transmission parameter according to the number of times of updating transmission data of each transmission parameter in the data types.

In this embodiment, all transmission parameters are classified according to the data types of the transmission parameters, so as to obtain a classification result of the transmission parameters, and the transmission priority is updated independently for the transmission parameters included in the classification result of each transmission parameter, so that the data size of the transmission parameters during the priority ordering process is reduced, and the priority ordering process time is shortened.

In one embodiment, the data types include dynamic data types and static data types. The specific processing procedure of step 602 may further update the transmission priority according to the classification result of the transmission parameters divided by the data types, which includes the following steps:

In a first mode, if the data type of the first transmission parameter is a dynamic data type, the transmission parameters of the dynamic data types in the transmission parameters are sequenced according to the sequence of the updating times of the transmission data in the first preset period from big to small, so as to obtain a sequencing result of the transmission parameters of the dynamic data types.

In the implementation, the description of the transmission priority update is made taking the data update of any transmission parameter after classification as an example. Specifically, in the classified data, if the data type of the first transmission parameter in which the data update occurs is a dynamic data type, the transmission priority is updated only in each transmission parameter of the dynamic data type in which the data update occurs, as shown in fig. 7, and in the transmission parameters of the dynamic data type, the transmission data update times in the same first preset period are ordered according to the order from large to small, so as to obtain the ordering result of the transmission parameters of each dynamic data type.

Optionally, as shown in fig. 7, in the transmission parameters of the static data types, for the update of the transmission data does not occur in the first preset period, the update times of the transmission data are kept unchanged, that is, the update times are zero times, the update times of the transmission parameters of the corresponding static data types are ordered in parallel, and if the minimum ordering of the dynamic data types is the 4 th bit, all the static data types are the 5 th bit in parallel.

And determining the transmission priority corresponding to the transmission parameters of the dynamic data type according to the sequencing result.

In an implementation, the BMC node determines, according to the ordering result, a transmission priority corresponding to a transmission parameter of the dynamic data type. The determining of the transmission priority for the obtained sorting result is the same as the processing procedure in step 502, and the embodiment of the present application is not repeated.

And if the data type of the first transmission parameter is the static data type, sequencing the transmission parameters of the static data type in the transmission parameters according to the sequence of the updating times of the transmission data in the first preset period from big to small, and obtaining a sequencing result of the transmission parameters of the static data type.

In the implementation, the description of the transmission priority update is made taking the data update of any transmission parameter after classification as an example. Specifically, in the classified data, if the data type of the first transmission parameter in which the data update occurs is a static data type, the transmission priority is updated only in each transmission parameter of the static data type in which the data update occurs, and the transmission priority is ordered according to the order of the number of times of the transmission data update in the same first preset period from large to small, so as to obtain the ordering result of the transmission parameters of each static data type.

And determining the transmission priority corresponding to the transmission parameters of the static data type according to the sequencing result.

In implementation, the BMC node determines, according to the sorting result, a transmission priority corresponding to a transmission parameter of the static data type. The determining of the transmission priority for the obtained sorting result is the same as the processing procedure in step 502, and the embodiment of the present application is not repeated.

Alternatively, the transmission priority of each transmission parameter of the static data type may be determined separately from the transmission priority of each transmission parameter of the dynamic data type, but the minimum transmission priority of each transmission parameter of the dynamic data type is prioritized over the maximum transmission priority of each transmission parameter of the static data type. If the minimum transmission priority in each transmission parameter of the dynamic data type is priority 4, the maximum transmission priority in each transmission parameter of the static data type is priority 5.

In an alternative embodiment, as shown in fig. 8, the method for determining a data type of a transmission parameter in the method includes the following steps:

In step 801, the accumulated update times of the transmission data of each transmission parameter in the transmission communication list are counted in a second preset period.

In the implementation, the second preset period is greater than the first preset period, and optionally, the second preset period may be in a multiple relationship with the first preset period, in the second preset period, the data change of each transmission parameter in the transmission communication list gradually tends to be stable, that is, has a stable change frequency, and then the BMC node counts the accumulated update times of the transmission data of each transmission parameter in the transmission communication list in the second preset period.

Step 802, calculating the data change rate of each transmission parameter according to the accumulated update times and the duration of the second preset period.

And dividing the accumulated update times with the duration of the second preset period according to the accumulated update times of each transmission parameter to obtain the data change rate of each transmission parameter.

Step 803, determining the data type corresponding to each transmission parameter according to the data change rate and a preset change rate threshold.

Wherein the data types include dynamic data types and static data types.

In implementation, a change rate threshold of the transmission parameter in a second preset period is preset in the BMC node, according to the change rate threshold, the BMC node compares the data change rate of each transmission parameter with the preset change rate threshold, as shown in fig. 9, and if the data change rate is greater than or equal to the preset change rate threshold, determines that the data type of the transmission parameter is a dynamic data type. If the data change rate is smaller than the preset change rate threshold value, determining that the data type of the transmission parameter is a static data type. Further, transmission parameters can be classified into two categories according to the division of data types.

In an alternative embodiment, as shown in fig. 10, the specific process of step 103 is as follows:

in step 1001, in the transmission communication list, according to the transmission priority order of the transmission parameters, the transmission check values corresponding to the transmission data of the transmission parameters are sequentially read.

In an implementation, the CMM sends a data query request to the BMC node, and according to the trigger of the data query request, the BMC may further read a transmission check value of each transmission parameter stored in the current transmission communication list, specifically, in the transmission communication list, the BMC sequentially reads, according to a transmission priority order of the transmission parameters, the transmission data of the transmission parameters, and the transmission check value corresponding to the transmission data, for example, in the transmission communication list, the BMC first reads, as the transmission parameter with a priority of 1, where the transmission parameter is sensor information, and reads, as the current transmission data and the corresponding transmission check value of the transmission parameter, that is, the sensor information.

Step 1002, when the transmission check value corresponding to the transmission data of the transmission parameter is read, determining that the transmission data is the target transmission data according to the transmission check value corresponding to the transmission data and the received reference check value, and sending the target transmission data and the transmission check value corresponding to the target transmission data to the data requester.

In implementation, for the read transmission check value corresponding to the transmission data, the BMC node may identify and send the transmission check value one by one, specifically, each time the transmission data of one transmission parameter and the transmission check value corresponding to the transmission data are read, the transmission check value corresponding to the transmission data is directly utilized to compare with the received reference check value of the same transmission parameter, if the transmission check value corresponding to the transmission data is inconsistent with the received reference check value, the transmission data is determined to be the target transmission data, and the transmission check value of the target transmission data are directly sent to the data requester (i.e. CMM).

Optionally, if the transmission check value corresponding to the transmission data is consistent with the received reference check value of the same transmission parameter, it indicates that the transmission data is not substantially updated, where substantially updated means that the transmission data of the numerical transmission parameter is changed in numerical value in a first preset period, or the transmission data of the state information transmission parameter is changed from 1 to 2 and then from 2 to 3 in the first preset period, corresponding to different state information in the first preset period, for example, such change is that the numerical value of the transmission data is substantially updated. In another example, the alarm information is converted from the temperature alarm information to the power consumption alarm information, etc., which indicates that the state transmission data is substantially updated. If the transmission data of the numerical transmission parameter is changed from 1 to 2 and then from 2 to 1, the corresponding transmission check value of the data value 1 corresponding to the current transmission data is consistent with the received reference check value based on the first transmission data 1, and the transmission data is not substantially updated.

In this embodiment, whether the transmission data of the transmission parameter is updated is identified by comparing the received reference check value with the transmission check value of the transmission data, when the transmission data of the transmission parameter with the update is identified, the transmission data with the update is taken as the target transmission data, the data transmission is performed, the data amount of the total transmission data required to be transmitted is reduced, the transmission time is reduced, meanwhile, the update of the transmission parameter is identified, the transmission data is immediately transmitted, and for the data with frequent data update, the data can be identified earlier according to the transmission priority, and meanwhile, the data transmission is realized earlier, so that the real-time performance of the transmission data is improved.

The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
