Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

Please refer to FIG. 1 , which is a block diagram of the server system of the present invention. The server system 100 includes nodes 110_1˜110_N, an extracting unit 120 , a control unit 130 , a checking unit 140 and a judging unit 150 , wherein N is a positive integer greater than 1. The server system 100 is, for example, a container data center (DataCenter) that provides Infrastructure as a Service (IaaS). Each of the nodes 100_1 to 110_N has node information. The extracting unit 120 is coupled to the nodes 110_1-110_N, and is used for extracting node information, so as to obtain the node types (NodeType) of the nodes 110_1-110_N. The node types are, for example, Service Node, Computing Node, and Storage Node.

The control unit 130 is coupled to the nodes 110_1-110_N and the capture unit 120, and is used for controlling the power-on of the nodes 110_1-110_N and starting the operating system (Operation System, OS) of the nodes 110_1-110_N. The checking unit 140 is coupled to the nodes 110_1-110_N, and is used for checking the operating system and a plurality of software package data (Software Package) of the nodes 110_1-110_N, so as to generate checking results. The judgment unit 150 is coupled to the inspection unit 140 , the control unit 130 and the retrieval unit 120 for receiving and judging whether the inspection result meets the requirement of the node type.

If it is judged that the check result meets the requirement of the node type, the control unit 130 adds the nodes 110_1 - 110_N to the server system 100 . If it is judged that the inspection result does not meet the requirements of the node type, the control unit 130 can install the operating system and a plurality of software package data to the nodes 110_1~110_N according to the node type and the installation file, so that the nodes 110_1~110_N have the relevant information that meets the node type. Operating system and software.

The above is a brief description of the internal components of the server system 100 and their coupling relationship. Hereinafter, the operation of the server system 100 after node replacement will be further described. For convenience of description, the node 110_1 will be used as an example below, and it is assumed that the node 110_1 is a node after component replacement, and the node 110_1 has an operating system.

First, the server system 100 detects that the node 110_1 is damaged, and notifies the user. After the user learns of the aforementioned damage, the damaged element of the node 110_1 is pulled out, and a new element is replaced to the node 110_1 .

Next, the capturing unit 120, for example, sends an Intelligent Platform Management Interface (IPMI) command to the baseboard management controller (BMC) on the node 110_1, so as to request the baseboard management controller to obtain the node information of the node 110_1 and It is sent back to the capture unit 120 . Then, the extracting unit 120 can obtain the node type (such as a service node, a computing node, or a storage node) of the node 110_1 according to the node information, so as to perform subsequent processing.

After obtaining the node type of the node 110_1 , the control unit 130 controls the node 110_1 to start up, and starts the operating system of the node 110_1 . Then, after the operating system booting is completed, the checking unit 140 checks the operating system and software package data of the node 110_1 to generate a checking result, and transmits the checking result to the judging unit 150 . Wherein, the inspection result includes, for example, the type and version of the operating system and software package data.

Next, the judging unit 150 judges whether the inspection result meets the requirement of the node type. If it is judged that the check result meets the requirement of the node type, the judgment unit 150 for example generates a judgment signal to the control unit 130, and the control unit 130 adds the node 110_1 to the server system 100 accordingly for operation. If it is judged that the check result does not meet the requirements of the node type, the judgment unit 150, for example, generates a judgment signal to the control unit 130, and the control unit 130 accordingly installs the operating system and software package data to the node 110_1 according to the node type and the installation file, so that The node 110_1 joins the operation of the server system 100 . In this way, after the node 110_1 is replaced, the server system 100 can automatically determine whether the node 110_1 can directly join the operation of the server system 100 or needs to reinstall the operating system and software package data, thereby increasing the convenience of use.

Next, another example will be used to describe the processing operation of the server system 100 after node replacement. In addition, the node 110_1 is taken as an example for illustration, and it is assumed that the node 110_1 is a node after element replacement.

After the node 110_1 is replaced, the capture unit 120 sends an intelligent platform management interface command to the baseboard management controller on the node 110_1 to request the baseboard management controller to obtain the node information of the node 110_1 and send it back to the capture unit 120 . Then, the extracting unit 120 can obtain the node type of the node 110_1 (such as a service node, a computing node, or a storage node) according to the node information.

Afterwards, the control unit 130 controls the node 110_1 to start up, and executes a self-starting test program, such as a basic input output system (Basic Input Output System, BIOS) self-test program (PowerOn SelfTest, POST). Next, the judging unit 150 judges whether the node 110_1 has the network boot mode, that is, judges whether the boot flag of the node 1101 is set to have the network boot mode. Wherein, the network boot mode is, for example, Preboot eXecution Environment (PXE) boot, that is, the node 110_1 can use the network boot mode to install the operating system and software package data through the network card.

Next, if the boot flag of the node 110_1 does not have the network boot mode, the judgment unit 150 will judge that the node 110_1 does not have the network boot mode, for example, to generate a judgment signal to the control unit 130, and the control unit 130 controls the node 110_1 to start the operation accordingly. system. Next, during the startup process of the operating system, the timer configured by the judging unit 150 (for example, FRB4timer) will time the startup process of the operating system, so as to judge whether the startup of the operating system can be completed within a preset time. Wherein, the preset time can be adjusted by the user according to the requirement.

If it is determined that the operating system has been activated within the preset time, it means that the operating system is operating normally (ie, no error occurs), and the judging unit 150 for example generates a judging signal to the checking unit 140 . Next, the check unit 140 checks the operating system and software package data of the node 110_1 to generate a check result. That is, the type and version of the operating system and software package qualifications are checked. Afterwards, the checking result is sent to the judging unit 150 .

Next, the judging unit 150 judges whether the inspection result meets the requirement of the node type. If it is judged that the checking result meets the requirement of the node type, the judging unit 150 generates a judging signal to the control unit 130 , for example. Then, the control unit 130 adds the node 110_1 to the server system 100 accordingly, that is, adds the node 110_1 to the operation of the server system 100 .

Following the above-mentioned judging whether the node 110_1 has the network boot mode, if the boot flag of the judging node 110_1 has the network boot mode, indicating that the node 110_1 can be booted in the network boot mode, the judging unit 150 for example generates a judging signal to the control unit 130 . Then, the control unit 130 installs the operating system and software packaging data required by the node 110_1 to the node 110_1 according to the node type and the installation file (such as an automatic installation file, Kick Start File), so that the node 110_1 has the original operation before the replacement type.

Following the aforementioned determination of whether the operating system has been started at the preset time, if it is determined that the operating system has not been started at the preset time, it means that the operating system is abnormal (that is, an error has occurred) or that the node 110_1 is not equipped with an operating system, then determine The unit 150 for example generates a judgment signal to the control unit 130 . Then, the control unit 130 accordingly sets the boot flag of the node 110_1 to have a network boot mode, such as a one-time network boot mode. That is to say, when the node 110_1 uses the network boot mode and installs an operating system through, for example, a network card, the boot flag of the node 110_1 does not have the network boot mode.

After the aforementioned boot flag is set, the control unit 130 will control the node 110_1 to reboot, so that the node 110_1 executes the self-test procedure again. Next, the judging unit 150 judges that the boot flag of the node 110_1 has a network boot mode, and for example generates a judging signal to the control unit 130 . After that, the control unit 130 will make the node 110_1 install the operating system and software package data to the node 110_1 through the network according to the node type and the installation file of the node 110_1, so that the node 110_1 has the original operation type before replacement.

Undertake the aforementioned judgment whether the inspection result meets the requirements of the node type, if the judgment inspection result does not meet the requirements of the node type, it means that all the operating system and software package data of the node 110_1 do not conform to the original type, so the judgment unit 150, for example, generates a judgment signal to control unit 130 . Then, the control unit 130 sets the boot flag of the node 110_1 to have a network boot mode accordingly.

Afterwards, the control unit 130 controls the node 110_1 to reboot, so that the node 110_1 executes the self-test procedure again. Next, the judging unit 150 judges that the boot flag of the node 110_1 has a network boot mode, and for example generates a judging signal to the control unit 130 . After that, the control unit 130 will make the node 110_1 install the operating system and software package data to the node 110_1 through the network according to the node type and the installation file of the node 110_1, so that the node 110_1 has the original operation type before replacement.

Undertake the aforementioned judging whether the inspection result meets the requirements of the node type, if the judging inspection result partially meets the requirements of the node type, indicating that the operating system of the node 110_1 partially matches the software package data, then the judging unit 150 further judges the operation configured by the node 110_1 Whether the system meets the requirements of the node type. If it is determined that the operating system meets the requirements of the node type, the determination unit 150 generates a control signal to the control unit 130 , for example. Then, the control unit 130 installs relevant software package data to the node 110_1 according to the node type of the node 110_1 , so that the node 110_1 has the original operation type before replacement.

On the other hand, if it is determined that the operating system does not meet the requirements of the node type, the determination unit 150 for example generates a determination signal to the control unit 130 . Then, the control unit 130 sets the boot flag of the node 110_1 to have a network boot mode accordingly.

Afterwards, the control unit 130 controls the node 110_1 to reboot, so that the node 110_1 executes the self-test procedure again. Next, the judging unit 150 judges that the boot flag of the node 110_1 has a network boot mode, and for example generates a judging signal to the control unit 130 . After that, the control unit 130 will make the node 110_1 install the operating system and software package data to the node 110_1 through the network according to the node type and the installation file of the node 110_1, so that the node 110_1 has the original operation type before replacement.

In addition, after the above-mentioned node 110_1 reinstalls the operating system and software package data through the network boot mode, the above-mentioned processing operations can be repeated until it is determined that the operating system and software package data installed on the node 110_1 meet the requirements of the node type. Add the node 110_1 into the operation of the server system 100 .
