Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application.

At present, in order to avoid the phenomenon of power supply surge caused by the simultaneous starting of a large number of servers in a data center after power supply. The surge phenomenon not only easily causes that the server cannot be started successfully, but also other devices which adopt the same power supply equipment with the server are easily damaged.

In the related art, during the starting process of the server, a baseboard management controller disposed in the server randomly generates a random delay interval, and then after the random delay interval, the starting process of the server is executed. However, by adopting the above method of randomly generating the delay interval, there is still a phenomenon that a certain probability causes a large number of servers started at the same time.

The application provides a server starting method and device based on a memory identifier, and the method is applied to a baseboard management controller in a server. When the baseboard management controller receives an instruction for indicating the starting of the server, the baseboard management controller can acquire a first configuration data for indicating the corresponding relation between the identification of a memory arranged in the server and the identification and starting information of the memory, and second configuration data for indicating the starting time interval. And then the baseboard management control controller determines starting data required by starting the server based on the acquired data, so that batch starting of the server is completed, and the power supply surge phenomenon caused by simultaneous starting of a large number of servers is avoided.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a flow chart of a server starting method based on identification of a memory according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:

S101, responding to a starting instruction, and acquiring an identifier, first configuration data and second configuration data of a memory from the memory connected with a baseboard management controller; the starting instruction is used for indicating the server to start; the first configuration data is used for indicating the mapping relation between the identification of the memory and the starting information, and the starting information characterizes the starting batch which is started by the server; the second configuration data characterizes a start-up time interval;

an application scenario corresponding to the embodiment is a scenario in which a large number of servers need to be started. The method provided in this embodiment is implemented by a baseboard management controller in a server. Specifically, a baseboard management controller (Baseboard Management Controller) and a memory are included in the server.

In this embodiment, after the baseboard management controller in the server receives the start-up instruction for instructing to start up the server, the start-up procedure of starting up the server is not immediately executed, but it is first determined whether the server can be started up immediately.

Specifically, in this embodiment, a memory is typically provided in the server, for storing data, a startup program, an initialization program, and the like, which are required to be configured by the server, and the memory has a unique identifier. In this embodiment, the memory may be a memory for storing a corresponding initialization program for initializing the configuration server. Here, only the memory having the above-described function will be described as an example. In practical applications, the memories for the remaining uses may be selected, and the type of the selected memories is not particularly limited.

In this embodiment, the memory connected to the baseboard management controller includes not only the identifier of the memory, but also the first configuration data and the second configuration data. The first configuration data may be understood as a pre-configured mapping relationship between an identifier of the memory and start information corresponding to the server. In this embodiment, the start information is specifically used to characterize which batch the server starts, that is, the start batch corresponding to the server.

Specifically, in one example, the first configuration data may specifically include a memory identifier and a correspondence between a modulo result of a fixed value and the start information. For example, assuming that the identifier of the memory is a decimal value, when the fixed value is 10, the modulo result equivalent to storing the identifier (i.e., the remainder of the identifier of the memory divided by the fixed value) includes 9 possible values of 0-9, equivalent to dividing the server into 10 batches altogether, the corresponding startup information for which the modulo result is 0 is characterized as the first startup batch, and so on. When 5 batches need to be divided, at this time, the fixed value may be 5, and the corresponding remainder value includes 5 cases, which is equivalent to dividing into 5 batches, that is, may be located in the same starting batch with the same modulo result. Then the first configuration data may specifically include the above modulo arithmetic (i.e. the identity of the memory and the remainder of the fixed value) and the preset fixed value.

In another example, the first configuration data may also directly store preset startup information corresponding to the identifier of each memory one to one. So that the start information can be determined subsequently from the identification of the memory.

In addition, the second configuration data is used to characterize the corresponding start-up time intervals between start-up batches.

Specifically, in one example, the start time intervals corresponding to two adjacent start information (i.e., two adjacent start batches) may be the same, and further, the second configuration data at this time may be a value of one time interval;

in another example, each boot batch corresponds to a boot time interval and an interval period; that is, each start-up batch corresponds to a first start-up time and a second start-up time, and the server corresponding to the start-up batch needs to be started between the first start-up time and the second start-up time, wherein the first start-up time is smaller than the second start-up time. And, after the second start-up time and the time interval, the server of the next batch can be started up. (corresponding to the second start-up time and then delaying the interval period, i.e. reaching the first start-up time corresponding to the next start-up batch). At this time, two interval values, i.e., a first interval and a second interval, may be set in the second configuration data. Wherein the first interval characterizes an interval between times at which servers corresponding to two adjacent start-up batches can start up earliest (i.e., an interval of first start-up times corresponding to the two adjacent start-up batches, respectively), and in addition, the second interval in the second configuration data is used to characterize a time interval between the first start-up time and the second start-up time corresponding to the same start-up batch, and the first interval is greater than the second interval (wherein a difference between the first interval and the second interval may characterize the interval period). Further, by setting the second configuration information in this example, a certain redundancy duration may be set for the start-up time corresponding to each start-up lot.

S102, determining starting data of the server according to the identification of the memory, the first configuration data and the second configuration data.

For example, after the baseboard management controller obtains the identifier of the memory, the first configuration data and the second configuration data, the starting information corresponding to the identifier of the memory may be further determined according to the identifier of the memory and the first configuration data; and further combining the starting information to determine the starting interval time corresponding to the server.

For example, when the first configuration data includes the modulo algorithm and a preset fixed value, at this time, the modulo processing may be directly performed on the obtained identifier of the memory based on the modulo algorithm and the preset fixed value, and the remainder obtained by the modulo processing may be used as the start information corresponding to the memory. Or directly searching the starting information corresponding to the identifiers of the memories which are recorded in the first configuration data in a one-to-one correspondence manner, and determining the starting information corresponding to the acquired identifiers of the memories.

In addition, the startup data mentioned in this embodiment may be used not only to characterize the startup interval time, but also further include execution time of the task to be executed, for example, the baseboard management controller may infer the startup time corresponding to the server according to the determined startup interval time, and when the server corresponds to a plurality of tasks to be executed, may also allocate execution time to each task to be executed, so as to ensure that the task to be executed may be executed automatically. Or, the starting data also includes a storage location of the starting firmware, so that the starting of the server can be completed according to the starting firmware in the subsequent starting process.

S103, starting the server according to the starting data of the server.

For example, after determining the startup data, the baseboard management controller may control the server to start based on the acquired startup data. For example, the timing process may be performed according to a start time interval included in the start data, and after the timing duration reaches the delay interval, further according to a storage location of the start firmware in the start data, the start firmware on which the server is started depends is obtained, and the start of the server is completed.

It can be understood that in this embodiment, by configuring the first configuration data and the second configuration data in the memory, when the baseboard management controller controls the server to start, the startup data corresponding to the server is obtained based on the unique identifier corresponding to the memory and the configuration data. And after determining that the starting interval time corresponding to the starting data is reached, controlling the server to start. Furthermore, by adopting the delay starting mode of the server, the power supply surge phenomenon caused by the simultaneous starting of a large number of servers can be avoided, the protection of power supply equipment, the server connected with the power supply equipment and other devices needing power supply is facilitated, and the damage of the devices is avoided.

Fig. 2 is a flowchart of a server startup method based on a memory identifier according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:

s201, a chip selection signal is sent to a first port of a memory in response to a starting instruction; wherein the chip select signal is used for controlling the memory to be in a readable state;

an application scenario corresponding to the embodiment is a scenario in which a large number of servers need to be started. The method provided in this embodiment is implemented by a baseboard management controller in a server. Specifically, a baseboard management controller (Baseboard Management Controller) and a memory are included in the server, and the memory has a unique identification. In this embodiment, the memory may be a memory for storing a corresponding initialization program for initializing the configuration server. Here, only the memory having the above-described function will be described as an example. In practical applications, the memories for the remaining uses may be selected, and the type of the selected memory is not particularly limited in this embodiment.

Illustratively, in this embodiment, the baseboard management controller and the memory each have 4 ports. Fig. 3 is a schematic diagram of a connection mode between a baseboard management controller and a memory according to an embodiment of the present application. Wherein the first port of the baseboard management controller is connected with the first port of the memory. When the baseboard management controller receives the starting instruction, the baseboard management controller firstly sends a chip selection signal to the memory through the first port of the baseboard management controller and the first port of the memory in sequence so as to select the memory and control the memory to be in a readable state.

S202, sending a clock signal to a second port of the memory and sending a request signal to a third port of the memory; wherein the clock signal is used to provide a time reference to the memory; the request signal characterizes an identification of a memory to which the request memory corresponds.

In this embodiment, the baseboard management controller may further send a clock signal to the memory sequentially through the second port of the baseboard management controller and the second interface of the memory, so that clock synchronization between the baseboard management controller and the memory may be performed, which is beneficial to ensuring accuracy of data transmission between the memory and the baseboard management controller. After the baseboard management controller sends the clock signal and the chip select signal to the memory, the further baseboard management controller sends a request signal to the memory based on the third port of the baseboard management controller and the third port of the memory, so that after the memory obtains the request signal, the memory identifier stored in the memory can be sent to the baseboard management controller.

S203, receiving the identification of the memory returned by the fourth port of the memory.

For example, after the request signal is sent, the baseboard management controller may receive the identification of the memory returned by the fourth port of the baseboard management controller based on the fourth port of the memory.

It can be understood that in this embodiment, when data transmission is performed between the baseboard management controller and the memory, the memory is requested to return the corresponding identifier by sending the chip selection signal, the clock signal and the request signal, so as to ensure that the baseboard management controller can accurately acquire the memory identifier corresponding to the memory.

In one example, step S203 includes the steps of: "according to the sending end time and preset waiting interval of the request signal, confirm the starting time; the starting time is the starting time of the memory to send the identification of the memory; determining that the feedback signal is a memory identifier sent by a memory; the feedback signal is a signal sent to the baseboard management controller by the fourth port of the memory after the starting time. "

Illustratively, in this embodiment, when the memory feeds back the identification of the memory to the baseboard management controller through the fourth port of the memory, the memory does not return immediately after receiving the request signal, but a certain period of time is required. Wherein, the time interval (i.e. the above-mentioned preset waiting interval) between the memory receiving the complete request signal and the memory sending the memory identification to the baseboard management controller is pre-agreed between the baseboard management controller and the memory. After the baseboard management controller determines that the request signal is sent, determining the time for the memory to send the identification of the memory according to the preset waiting interval, and based on the determined time, a feedback signal for representing the identification of the memory in the signals sent by the fourth port of the memory.

Fig. 4 is a schematic diagram of signal transmission according to an embodiment of the present application, as shown in fig. 4. In the figure, signal 1, signal 2, signal 3 and signal 4 are used to characterize the signals at the first port of the memory, the second port of the memory, the third port of the memory, the fourth port of the memory, respectively. Wherein signal 1 may be representative of a chip select signal, when the baseboard management controller controls the level of the first port of the memory to be low, at this time, the memory is controlled to be in a selected readable state. Signal 2 is a clock signal. The clock signal may be in a low-level preceding mode or a high-level preceding mode, and in this embodiment, in the low-level preceding mode. In addition, the period corresponding to the first segment in the clock signal is the period of the memory receiving the request signal, i.e. the period of time occupied by the corresponding request signal. The time length corresponding to the second section, the third section, the fourth section and the fifth section in the clock signal is a preset waiting interval. After the preset wait interval is over, the memory starts to feed back the identification of the memory (i.e., the location corresponding to the identification in signal 4 in the figure) to the baseboard management controller through the fourth port. And, after the end of the identification acquisition of the memory, the baseboard management controller may control the signal 1 to be set to a high level so that the memory is in an unselected state. When the memory feeds back the identification of the memory to the baseboard management controller, the characters at the high position can be fed back preferentially, and the characters can be fed back sequentially from high to low.

It can be understood that in this embodiment, when the baseboard management controller receives the identifier of the memory fed back by the memory, the real time of the feedback identifier of the memory needs to be determined based on the preset waiting interval between the baseboard management controller and the memory, so as to obtain an accurate identifier.

S204, acquiring first configuration data and second configuration data; the starting instruction is used for indicating the server to start; the first configuration data is used for indicating the mapping relation between the identification of the memory and the starting information, and the starting information characterizes the starting batch which is started by the server; the second configuration data characterizes a start-up time interval.

Wherein the first configuration data comprises: a first total number, a plurality of lot data; the batch data corresponds to the second total number one by one; the batch data comprises the corresponding relation between the identification of the memory and the starting batch under the second total number corresponding to the batch data; the first total number is the total number of starting batches actually corresponding to the starting process of the server at the time; the start-up data includes a first time; the second total number is the total number of divided start-up batches; first time characterizes start-up time of a server

In this embodiment, a plurality of lot data are included in the first configuration data, where one lot data may be understood as a server-initiated lot batch mode. And, the second total number corresponding to the different batch data is different, that is, the different batch data characterization divides the server startup batch into different batch numbers, that is, the second total number corresponding to the batch data is used to characterize how much startup information, that is, how many startup batches, are included in the batch data. And, the batch data is also used to indicate correspondence between the identification of the memory and the starting batch.

In addition, a first total number, i.e. the total number of batches that need to be batched, actually selected at the time of the server start-up, is also included in the first configuration data.

S205, determining batch data corresponding to the first total quantity; and determining the starting batch corresponding to the server according to the batch data corresponding to the first total number and the identification of the memory.

For example, after the baseboard management controller obtains the first configuration data, the lot data corresponding to the second total number that is the same as the first total number is first determined as the lot data corresponding to the first total number based on the first total number included in the first configuration data.

And further, after the batch data corresponding to the first total number is obtained, the actual starting batch corresponding to the server can be determined by combining the obtained identifier of the memory in the server.

In one example, the lot data is preset with a plurality of identifiers of the memories and a start-up lot corresponding to the identifier of each memory, and then, after the baseboard management controller determines that the lot data (i.e., the lot data corresponding to the first total number) needs to be selected actually, the start-up lot corresponding to the identifier of the memory included in the server may be determined by matching the identifiers of the memories in the lot data.

In one example, if the identifier of the memory includes N characters, the first configuration data is specifically configured to indicate a mapping relationship between M characters in the identifier of the memory and the start batch; n is a positive integer greater than 1; m is a positive integer less than N. Specifically, when the identifier of the memory is composed of N characters, at this time, when setting the batch data in the first configuration data, the server may be batched according to the values of M characters at the preset position in the identifiers of the memory, for example, the identifier having the same last character among the identifiers of the plurality of memories may be used as the identifier of the memory corresponding to one start batch. Furthermore, in the above manner, the starting batch corresponding to the identifier of each memory does not need to be stored in the first configuration data, and only the correspondence between the M characters and the starting batch needs to be set. After the identification of the memory is obtained, M characters at the preset position are directly extracted and compared with the corresponding relation in the first configuration data, and then the starting batch corresponding to the server can be determined. It can be understood that, by the setting manner of the first configuration data, the storage space occupied by the first configuration data can be reduced, which is beneficial to saving the storage resources corresponding to the server.

S206, determining the first time according to the starting batch and the second configuration data corresponding to the server.

In this embodiment, after the baseboard management controller determines the start-up batch corresponding to the server, the start-up time corresponding to the server, that is, the first start-up time, may be further determined in combination with the start-up time interval represented in the second configuration data.

For example, the second configuration data may include a fourth time corresponding to the batch data, where the fourth time may be used to characterize a start-up time interval between a first start-up batch and a last start-up batch corresponding to the batch data. That is, for example, when divided into 5 packets, the corresponding fourth time may be 1s; when divided into 10 packets, the corresponding fourth time may be 2s; after the batch data corresponding to the first total number is determined, a fourth time corresponding to the batch data may be determined. And then, combining the starting batch where the current server is positioned and the fourth time to determine the first time corresponding to the batch.

Or the second configuration data is directly adjacent to the time interval of the starting batch, and when the starting batch of the server is 2, the corresponding first time is the result of summing the current time and the second configuration data.

In one example, when the total number of batches divided by the server needs to be adjusted, at this time, adjustment of the batch number may be performed by adjusting the first total number in the first configuration information.

It can be understood that in this embodiment, the first configuration data includes a plurality of lot data and a first total number, and when the number of lots divided by the server needs to be adjusted, the adjustment of the number of lots can be achieved only by adjusting the value of the first total number, without setting the correspondence between the identification of the memory and the starting lot again.

In one example, on the basis of the above embodiment, the startup data further includes: a second time; the method further comprises the steps of:

further comprising determining a third time based on determining the first total number and the second configuration data; the third time is the starting time of the server of the last starting batch;

summing the third time and a preset value to obtain a second time; wherein the second time characterizes the time at which the server is started again after the first time failed to start.

In this embodiment, the startup data determined by the baseboard management controller further includes a second time, where the second time may be understood as a second time when the server fails to start at the first time, and the second time when the server starts is controlled again.

Specifically, in practical application, if the server cannot be started normally when it is started for the first time, at this time, the baseboard management controller may control the server to start again, and when the server is controlled to start again, the server is not controlled to restart immediately, but needs to wait until the server corresponding to the last start batch completes starting, and then restart the control server. That is, after the baseboard management controller determines the first time for characterizing the startup time of the server according to the identifier of the memory, the first configuration data, and the second configuration data, the startup time (i.e., the third time) of the server corresponding to the last startup lot may be further determined according to the actual total number of the total number of batches divided by the server in the first configuration data and the time interval characterized by the second configuration data. Then, the baseboard management controller can add the third time and the preset value to obtain a result, and the result is used as the restart time corresponding to the first unsuccessful start of the server.

It can be appreciated that in this embodiment, after the baseboard management controller determines the start time (i.e., the first time) corresponding to the server, the time for restarting the server after the start failure may further be determined. Specifically, it is necessary to restart again after a preset value time after the last batch of servers is started. Furthermore, by the mode, the phenomenon of power supply surge caused by a large number of servers which are required to be powered on and started at the same time and are caused by restarting the servers can be avoided.

S207, starting the server according to the starting data of the server.

For example, when the startup data of the server includes only the first time, the baseboard management controller may control the server to start at the first time according to the determined first time.

In some embodiments, the first configuration data is determined according to a priority of a task to be processed corresponding to the server; the priority of the task to be processed corresponding to the server is inversely proportional to the value of the starting information corresponding to the server.

In this embodiment, when determining the mapping relationship between the identifier of the memory indicated in the first configuration data and the startup information, the determination may be performed according to the priority of the task to be processed corresponding to each server at this time, that is, the higher the priority of the task to be processed corresponding to the server, the smaller the number of startup batches represented by the startup information corresponding to the server, and the earlier the time for the server to start.

In practical application, the priority of the task to be processed corresponding to the server may be determined according to the task deadline corresponding to the task to be processed, and the earlier the deadline, the higher the priority of the corresponding task to be processed. In addition, for two servers of the task to be processed with the same or similar task deadlines, the task processing duration corresponding to each task to be processed can be further determined in combination. For example, when two servers have the same or similar task deadlines and the two servers cannot be in the same startup information, at this time, the server of the task to be processed having a longer task processing duration may be preferentially started. In addition, in practical application, the mapping relationship indicated in the first configuration information can be further determined by combining the user priority of the user issuing the task to be processed.

It can be understood that in this embodiment, when the first configuration data is configured, the mapping relationship between the starting information of the server and the identifier of the memory may be determined in combination with the priority of the task to be processed corresponding to the server, so that by using the above method, it is ensured that the server having the task to be processed with a higher priority may be started as early as possible, so as to ensure that the task to be processed corresponding to the server is completed on time.

For example, the identifier of the memory in the related art includes 64-bit binary, and the identifier corresponding to the memory is a unique identifier set when the memory is shipped and cannot be changed.

Table 1 provides a batch illustration of this example

Because the identification of the memory is unique, and the identification of the memory has continuity, when the number of servers is large, at this time, the memory can be divided according to the last 4 bits corresponding to the identification of the memory, that is, when the number of servers is large, the probability that the last 4 bits corresponding to each possible identification of the memory appear is the same (that is, the number of servers corresponding to each last 4 bits is the same as the number of servers corresponding to the rest of last 4 bits).

In table 1, the first column of data lists 16 possible values corresponding to the last 4-bit character of the identification of the memory. And, the data of the rest columns in the characterization can be used for characterizing different division modes of the starting information. For example, in the table, the fifth column of data and the first column of data are combined, it can be seen that the fifth column of data represents that the server is divided into 3 pieces of start information, and the last 4 bits of the identifier of the memory corresponding to the start information of the first batch are respectively: 0000. 0001, 0010, 0011, 0100, 0101; the identified last 4 bits of the memory corresponding to the start information of the second batch are respectively: 0110. 0111, 1000, 1001, 1010; the identified last 4 bits of the memory corresponding to the starting information of the third batch are respectively: 1011. 1100, 1101, 1110, 1111.

It should be noted that the above-mentioned division manner of the last 4-bit character in the low-order character based on the memory identifier is only an illustration. In practical application, the last three bits or the last two bits can be selected for division. Alternatively, a discontinuous few-bit character, for example, the first last and third last bits may be selected, and the selection manner of the identification character of the memory is not particularly limited in this embodiment.

And then, the baseboard management controller determines the starting time corresponding to the starting of the server according to the acquired information. And then executing the BMC to execute timing processing, namely continuously judging whether the current time reaches the determined starting time. When the start-up time is reached, the server may be controlled to start up at this time. If the start time is not reached, the timer processing is continued.
