Referring to fig. 2, fig. 2 is a flowchart of a method for obtaining server resources according to an embodiment of the present invention.
Step S202, the cloud platform determines an initial binding relation between a baseboard management controller BMC and an intelligent network card of each server;
in this embodiment, the cloud platform may use a manner of performing communication interaction with the intelligent network card, or may also use a manner of performing reachability detection on a management address of the intelligent network card to preliminarily determine the intelligent network card bound by the BMC of each server, that is, obtain an initial binding relationship between the BMC of each server and the intelligent network card.

For the BMC of each server, the cloud platform may generate a first identification code and a random number of the BMC of each server in a similar manner, and send the first identification code and the random number to the intelligent network card bound by the BMC of each server according to an initial binding relationship.

In this embodiment, the intelligent network card extracts and stores the first identification code and the random number from the message sent by the cloud platform, then establishes an internal communication channel between the intelligent network card and the connected server, acquires the system information of the connected server through the internal communication channel, generates the second identification code based on the received random number and the system information of the connected server, and compares the generated second identification code with the received first identification code to determine whether the BMC of the server bound by the intelligent network card in the initial binding relationship is correct.
Step S210, each intelligent network card sends an initial binding relationship correct message to the cloud platform under the condition that the second identification code is the same as the received first identification code, and acquires the resource information of the connected server and sends the resource information to the cloud platform;
In this embodiment, if the second identification code is the same as the received first identification code after the comparison of the intelligent network card, it is indicated that the first identification code and the random number sent to the intelligent network card by the cloud platform are the first identification code and the random number of the BMC of the server connected to the intelligent network card, that is, the BMC of the server bound to the intelligent network card in the initial binding relationship is correct, then the intelligent network card sends an initial binding relationship correct message to the cloud platform, and sends the acquired information of the resources, such as the CPU model, the CPU core number, the memory, and the like, of the connected server to the cloud platform. It should be understood that the resource information of the server may be set according to actual situations, and the embodiment of the present invention is not limited.
And step S212, the cloud platform binds the intelligent network card corresponding to each initial binding relation correct message, the BMC of the server and the resource information of the server to obtain a resource binding relation.
In this embodiment, the cloud platform receives each initial binding relationship correct message and the resource information of the server corresponding to the initial binding relationship correct message, and binds the intelligent network card corresponding to each initial binding relationship correct message, the BMC of the server and the resource information of the server to obtain the resource binding relationship.
Based on the steps, the cloud platform determines an initial binding relation between the BMC of each server and the intelligent network card and sends the generated first identification code and random number of the BMC of each server to the intelligent network card bound by the BMC of each server; each intelligent network card establishes an internal communication channel between the intelligent network card and the connected server and generates a second identification code based on the system information of the connected server and the received random number, and each intelligent network card sends an initial binding relationship correct message to the cloud platform and sends the resource information of the connected server to the cloud platform under the condition that the second identification code is the same as the received first identification code; and the cloud platform binds the intelligent network card corresponding to each initial binding relation correct message, the BMC of the server and the resource information of the server to obtain the resource binding relation. Through communication interaction between the cloud platform and the intelligent network card, the binding relation among the intelligent network card, the BMC of the server and the server resources can be obtained and determined, so that the operation is simplified, and the efficiency and the accuracy are improved.
Optionally, for step S202, one possible implementation is provided by the embodiment of the present invention.
Step S202A-1, the cloud platform traverses the BMC address of each server, and sends a power-on starting instruction to the server corresponding to each BMC address, wherein the power-on starting instruction is used for indicating the server corresponding to the BMC address to power on and supply power for an intelligent network card connected to the server;
step S202A-3, after each intelligent network card is electrified, a request message carrying an own management address and running time length is sent to a cloud platform;
in this embodiment, the cloud platform traverses each BMC address in the BMC address list to establish an initial binding relationship between the BMC of the server and the intelligent network card by binding the BMC address with a certain management address.
The cloud platform sends a power-on starting instruction to a server corresponding to each BMC address, and the server can perform power-on starting operation and supply power for an intelligent network card connected to the server after receiving the power-on starting instruction.
The intelligent network card is powered on and started, and after the starting is completed, a pre-installed reporting program is executed to automatically send a request message to the cloud platform. For example, the intelligent network card uses HTTP or other protocols to generate a request message carrying its own management address and running time length, and continuously sends the request message to the cloud platform. It should be understood that the request message may also carry other parameters, which are not limited by the embodiment of the present invention.
Step S202A-5, when the binding state of the management address in the request message is unbound and the running time in the request message is less than a preset threshold, the cloud platform binds the BMC address corresponding to the current power-on instruction with the management address in the request message;
in this embodiment, the cloud platform receives a request message sent by the intelligent network card, and extracts parameters such as a management address and an operation duration carried in the request message. If the binding state of the management address in the request message received by the cloud platform is unbound and the operation time length is less than a preset threshold value, for example, 5 minutes, the intelligent network card corresponding to the management address in the request message received by the cloud platform is indicated to be the intelligent network card connected on the server which is just powered on, and then the BMC address corresponding to the current power-on instruction is bound with the management address in the request message. It should be understood that the preset threshold may be set according to practical situations, and embodiments of the present invention are not limited.
Optionally, the cloud platform further sends a response message to the intelligent network card corresponding to the management address in the request message, so that the intelligent network card stops sending the request message after receiving the response message.
Step S202A-7, the cloud platform obtains intelligent network cards bound by BMCs of all servers to obtain an initial binding relation;
in this embodiment, the cloud platform binds the BMC address of each server and the management address of each intelligent network card one by one according to the similar manner, so as to obtain the intelligent network card bound by the BMC of each server, and thus obtain the initial binding relationship.
Optionally, for step S202, another possible implementation manner is provided by the embodiment of the present invention.
Step S202B-1, the cloud platform traverses the BMC address of each server, and sends a power-on starting instruction to the server corresponding to each BMC address, wherein the power-on starting instruction is used for indicating the server corresponding to the BMC address to power on and supply power for the intelligent network card connected to the server;
step S202B-3, the cloud platform performs connectivity detection on each management address with the binding state being unbound, and binds the management address which is changed from unconnected to connected from the connected state with the BMC address corresponding to the current power-on instruction;
in this embodiment, the cloud platform traverses each BMC address in the BMC address list to establish an initial binding relationship between the BMC of the server and the intelligent network card by detecting reachability of a management address in the management address list after a certain server is specified to be powered on, and binding the BMC address of the server with the management address whose state changes.
The cloud platform sends a power-on starting instruction to a server corresponding to each BMC address, and the server can perform power-on starting operation and supply power for an intelligent network card connected to the server after receiving the power-on starting instruction.
And then the cloud platform detects the accessibility of each management address with the binding state being unbound, namely connectivity detection, if a certain management address is not reachable to be reachable, namely the connection state is not connected to be connected, the intelligent network card corresponding to the management address is the intelligent network card connected to the server which is just powered on and started, and then the BMC address corresponding to the current power-on and starting instruction is bound with the management address.
Step S202B-5, the cloud platform obtains the intelligent network card bound by the BMC of each server, and obtains the initial binding relation.
In this embodiment, the cloud platform binds the BMC address of each server and the management address of each intelligent network card one by one according to the similar manner, so as to obtain the intelligent network card bound by the BMC of each server, and thus obtain the initial binding relationship.
Optionally, for the process of generating the first identification code and the random number of the BMC of each server by the cloud platform in step S204, the embodiment of the present invention provides a possible implementation manner.
Step S204-1, the cloud platform obtains the device model number and the device serial number of the BMC of each server through the BMC address of each server, and generates a random number for the BMC of each server;
in step S204-3, the cloud platform calculates based on the device model number, the device serial number, the random number and the management address of the intelligent network card bound by the device model number and the random number of the BMC of each server according to a preset algorithm, and obtains a first identification code of the BMC of each server.
It will be appreciated that the manner in which the cloud platform generates the first identification code and the random number of the BMC of each server is similar, and for brevity, the BMC of one server will be described below as an example.
In this embodiment, the cloud platform generates a random number, namely rand_num, for the BMC of the server, and obtains information of the BMC of the server, such as a device model, namely bmc_type, and a device Serial number, namely bmc_serial, through the BMC address of the server.
And then the cloud platform calculates according to a preset algorithm based on the device model of the BMC of the server, namely BMC_Type, the device Serial number of the server, namely BMC_Serial, the random number of the server, namely RAND_Num, and the management address of the intelligent network card bound by the BMC of the server, namely NIC_Mgmt, and then the first identification code of the BMC of the server, namely H1, is obtained. In a similar manner, for the BMC of each server, the cloud platform may generate a first identification code and a random number for the BMC of each server.
It should be understood that the preset Algorithm may be MD5 (Message-Digest 5 algorism), or may be other algorithms set according to practical situations, which is not limited in the embodiments of the present invention.
