Description

Server system and node replacement method

technical field

The present invention relates to a server system (such as a cabinet-type data center) and a node replacement method, in particular to a server system and a node replacement method that can quickly perform a node replacement program.

Background technique

With the development of technology, computers all over the world can be connected through the Internet. A computer can exchange and access data with another computer through a network connection. In the client and server system architecture, the client and the server communicate through the network.

Generally speaking, the server system can be configured with multiple nodes, and each node runs multiple virtual machines (virtual machines, VMs) at the same time, so as to provide each user with an independent operating environment. Moreover, each node can be regarded as an independent computer, that is, each node has a memory, a storage space, a computing capability and a network connection function. Therefore, each node can run its own operating system, and each node can also communicate and transmit data through network equipment.

After the server system structure is completed, the deployment of the nodes must be completed, that is, the operating system, software package data and firmware package data required by each node must be installed, so that the server system can operate and provide services to users. However, when the hardware of any group of nodes in the server system is damaged, the nodes corresponding to this hardware will not be able to operate normally. At this time, since the inspectors cannot accurately know which specific hardware in the node is damaged, However, the detection can only be performed by removing and inserting the nodes into the server system in sequence, resulting in a waste of detection time.

Contents of the invention

The technical problem to be solved by the present invention is to provide a server system and a node replacement method, which can automatically determine whether a specific node or specific hardware in this node needs to be replaced according to the identification code of the node and the hardware configuration information of the hardware in the node. Replacement, allowing inspectors to quickly and easily replace nodes.

In order to achieve the above object, the present invention provides a node replacement method, which is suitable for a server system. The flow of steps for this node replacement method is described below. Detect whether the node is plugged into the server system, and generate a first prompt signal when detecting that the node is plugged into the server system, wherein the first prompt signal is used to indicate that the node cannot be removed from the server system. The first identification code of the node and the first hardware configuration information of the hardware in the node are detected. According to the first identification code and first hardware configuration information and the second identification code and second hardware configuration information before the node is inserted into the server system, it is judged whether the node or the hardware in the node has been replaced. If it is determined that neither the node nor the hardware in the node has been replaced, the power of the node is turned off to execute the node replacement procedure. If it is determined that the node or the hardware in the node is replaced, at least one of the operating system, software package data and firmware package data is installed on the node.

In one embodiment, after the step of installing at least one of the operating system, software package data, and firmware package data on the node, the following steps are further included. Continuously detect the status of the hardware in the node to determine whether there is an error in the hardware. If it is judged that the hardware has an irreparable error, then turn off the power of this node to execute the node replacement program. If it is judged that the number of recoverable errors generated by the hardware reaches the preset threshold value, a normal shutdown procedure is performed on the node, and a node replacement procedure is executed accordingly.

In one embodiment, the node replacement procedure includes the steps described below. Sets the node to initial mode. A second prompt signal is generated, wherein the second prompt signal is used to indicate that the node can be disconnected from the server system. Detect whether the node is unplugged from the server system. Detect if a node or another node is plugged into the server system. If it is detected that the node or another node is plugged into the server system, a first prompt signal is generated, and the steps after detecting the first identification code of the node and the first hardware configuration information of the hardware in the node are continued.

Following the above-mentioned embodiment, the step of detecting whether the node is disconnected from the server system further includes the steps described below. Set the first preset time and start timing. Determine whether the node has been disconnected from the server system. If it is determined that the node has not been disconnected from the server system, the first preset time is reset and timed again. If it is determined that the node is disconnected from the server system and the first preset time has elapsed, the steps after detecting whether the node or another node is plugged into the server system are performed.

Following the above-mentioned embodiments, the step of detecting whether the node or another node is plugged into the server system further includes the steps described below. Setting the first preset time and the second preset time and starting timing, wherein the second preset time follows the first preset time. Determine whether the node is plugged into the server system. If it is determined that the node has not been inserted into the server system, the first preset time is reset and the timing is restarted. If it is determined that the node is plugged into the server system and the first preset time has elapsed, then it is judged whether the node is still plugged into the server system during the second preset time. If it is determined that the node is disconnected from the server system within the second preset time, then continue with the steps after setting the node to the initial mode. If it is judged that the node has not been disconnected from the server system after the second preset time, a first prompt signal is generated, and the steps after detecting the first identification code of the node and the first hardware configuration information of the hardware in the node are continued.

In order to better achieve the above object, the present invention also provides a server system, which includes a node, a detection module, a prompt module and a processing module. Nodes have hardware. The detection module is connected to the node through communication. The detection module is used to detect whether the node is plugged into or removed from the server system, and is used to detect the first identification code of the node and the first hardware configuration information of the hardware. The prompt module communicates with the detection module, and the prompt module is used to generate a first prompt signal when the detection module detects that the node is inserted into the server system. Wherein, the first prompt signal is used to indicate that the node cannot be disconnected from the server system. The processing module is communicatively connected between the detection module and the node, and the processing module is used to judge the node or the hardware according to the first identification code and the first hardware configuration information and the second identification code and the second hardware configuration information before the node is inserted into the server system has been replaced. Wherein, if the processing module determines that neither the node nor the hardware has been replaced, then turn off the power of the node to execute the node replacement program; if the processing module determines that the node or the hardware has been replaced, then install the operating system, software package data and firmware on the node Packet data at least one of them.

In one embodiment, after the processing module installs at least one of the operating system, software package data, and firmware package data on the node, the processing module continues to determine whether a hardware error occurs. If the processing module determines that an unrecoverable error occurs in the hardware, the power of the node is turned off to execute the node replacement program. If the processing module judges that the number of recoverable errors generated by the hardware reaches the preset threshold value, it performs a normal shutdown procedure on the node, and executes the node replacement procedure accordingly.

In one embodiment, when the server system executes the node replacement procedure, the processing module sets the node to an initial mode. Then, the prompting module generates a second prompting signal, and the second prompting signal is used to indicate that the node can be disconnected from the server system. In addition, the detection module detects whether the node is disconnected from the server system, and then detects whether the node or another node is plugged into the server system after detecting that the node is disconnected from the server system. If the detection module detects that the node or another node is inserted into the server system, the prompt module generates a first prompt signal, and the detection module continues the processing procedure after detecting the first identification code of the node and the first hardware configuration information of the hardware.

Following the above-mentioned embodiment, the server system further includes a timing module, and the timing module is a communication connection detection module. When the detection module detects whether the node is disconnected from the server system, the timing module will set the first preset time and start timing. If the detection module detects that the node has not been disconnected from the server system within the first preset time, the timing module will reset the first preset time and start counting again. If the detection module detects that the node is disconnected from the server system and the first preset time has elapsed, the processing procedure after detecting whether the node or another node is inserted into the server system is continued.

Following the above-mentioned embodiment, the server system further includes a timing module, and the timing module is a communication connection detection module. When the detection module detects whether the node or another node is plugged into the server system, the timing module sets the first preset time and the second preset time and starts timing, wherein the second preset time follows the first preset time. If the detection module detects that the node has not been inserted into the server system within the first preset time, the timing module resets the first preset time and restarts timing. If the detection module detects that the node is plugged into the server system and the first preset time has elapsed, then the connection checks whether the node is still plugged into the server system during the second preset time. If the detection module detects that the node is disconnected from the server system within the second preset time, the connection processing module sets the node as the processing procedure of the initial mode. If the detection module detects that the node has not been removed from the server system after the second preset time, the prompt module generates a first prompt signal, and the detection module continues to detect the first identification code of the node and the first hardware configuration information of the hardware handler.

Technical effect of the present invention is:

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 functional block diagram of a server system according to an embodiment of the present invention. As shown in Figure 1, the server system 1 includes a node 10, a detection module 12, a prompt module 14, a processing module 16 and a timing module 18, wherein the detection module 12 is connected to the node 10 by communicating with the prompt module 14, the processing module 16 and the timing module 18. , and the node 10 is in communicative connection with the processing module 16 . The communication connection described in the present invention may be realized by a physical line connection or a wireless communication connection, which is not limited in the present invention. In practice, the server system 1 can be a cabinet-type data center (container data center), but not limited thereto. Each functional module of the server system 1 will be described in detail below.

The node 10 has at least one piece of hardware, and the hardware may include a baseboard management controller (baseboard management controller, BMC), a network interface controller (network interface controller, NIC, also known as a network card), a hard disk drive (hard disk drive, HDD) , DIMM (Dual In-line Memory Module) and central processing unit (CPU), etc., but not limited thereto. In addition, although FIG. 1 only shows a group of nodes, the server system of the present invention does not limit the number of nodes here.

The detection module 12 is used to detect whether the node 10 is plugged into or removed from the server system 1 , and is used to detect the first identification code of the node 10 and the first hardware configuration information of the hardware in the node 10 . In practice, the identification code of the node 10 may be a universal unique identifier (UUID), but not limited thereto. Generally speaking, this kind of UUID is composed of a string of 16-bit (also known as 128-bit) hexadecimal numbers, so that each node 10 can have unique identification information. Furthermore, This UUID can be obtained from the UUID column of the SMBIOS (System Management BIOS) Type1 data structure; the hardware configuration information of the node 10 can be calculated to obtain its unique 4-byte hardware signature (Hardware Signature), BIOS (Basic Input Output System ) will obtain the hardware configuration information during its POST (Power On Self Test) and store the hardware signature in the Hardware Signature column of the ACPI (Advanced Configuration Power Management Interface) FACS (Firmware ACPI Control Structure) table. This HardwareSignature column is available to quickly determine whether the hardware configuration information is different; moreover, it is possible to detect whether the node 10 is inserted or removed by pinging the NIC of the BMC on the node 10.

The prompt module 14 is used for generating a set of first prompt signals when the detection module 12 detects that the node 10 is plugged into the server system 1 , and the first prompt signals are used to indicate that the node 10 cannot be removed from the server system 1 . In addition, in some cases, the prompt module 14 generates a set of second prompt signals, and the second prompt signals are used to indicate that the node 10 can be disconnected from the server system 1 . In practice, the prompt module 14 can be a display module (such as electronic display components such as light-emitting diodes, display panels, and seven-segment displays) or a sound module (such as electronic sound components such as speakers and buzzers). No limitation is imposed here. If the prompt module 14 is a display module, the prompt signal is presented to the user in the form of image or light; if the prompt module 14 is a sound module, the prompt signal is presented to the user in the form of sound.

The processing module 16 is used to determine whether the node 10 or the hardware in the node 10 is It has been replaced; it should be known that "the second identification code and second hardware configuration information before the node 10 is inserted into the server system 1" is "the identification code and hardware configuration information of the node 10 when it was inserted into the server system 1 last time", and , if a new node 10 is inserted into the server system, its second identification code and second hardware configuration information are both empty. The timing module 18 is used to set at least one set of preset times and start timing. In some cases, the timing module 18 resets the timing to zero during the timing, so as to restart the timing.

In order to more clearly illustrate the actual operation of the server system 1 and the node replacement method of the present invention, please refer to FIG. 1 and FIG. 2A together. FIG. 2A is a flow chart of the steps of the node replacement method of the server system according to an embodiment of the present invention. As shown in Figure 2A, in step S200, the detection module 12 will detect whether the node 10 is inserted into the server system 1, and when detecting that the node 10 is inserted into the server system, the prompt module 14 will generate a set of first prompt signals, and enter the step S202. If the detection module 12 does not detect that the node 10 is inserted into the server system 1 , step S200 is repeated until the detection module 12 detects that the node 10 is inserted into the server system 1 .

In step S202 , the detection module 12 then detects the first identification code of the node 10 and the first hardware configuration information of one of the hardware in the node 10 . In step S204, the processing module 16 will determine whether the node 10 or the hardware in the node 10 is has been replaced. If the processing module 16 determines that the node 10 or the hardware in the node 10 has been replaced, execute step S206; if the processing module 16 determines that neither the node 10 nor the hardware in the node 10 has been replaced, execute step S208. It should be known that if the node 10 or its hardware has not been replaced, the operating system, software package data or firmware package data (not shown) can also be forced to be re-installed on the node 10, which can be applied to the actual situation as follows: when the node 10 just because the hardware on it produces hardware error because of bad contact, node 10 can be unplugged at this moment, make its hardware contact well then, and then node 10 is inserted back into server system 1 again.

In step S206 , the processing module 16 installs at least one of an operating system (operating system, OS), software package data (software package data) and firmware package data (firmware package data) on the node 10 . In step S208, the processing module 16 will power off the power of the node 10 to execute the node replacement procedure.

Please refer to FIG. 2B . FIG. 2B is a flowchart of steps of a node replacement method of a server system according to another embodiment of the present invention. As shown in Figure 2B, after the step of installing at least one of the operating system, software package data and firmware package data on the node (ie step S206), the detection module 12 or another group of monitoring modules (not shown) can continue The condition of the hardware in the node is accurately detected, so that the processing module 16 determines whether an error occurs in the hardware (that is, step S210). If the detection module 12 or another group of monitoring modules detects that the hardware in the node 10 produces an uncorrectable error (un-correct error), then perform step S212; if the detection module 12 or another group of monitoring modules detects that the node 10 When the number of correct errors generated by the hardware reaches a preset threshold value (default threshold value), step S214 is executed.

In step S212, since the hardware in the node 10 has an irreparable error, that is, the node 10 is damaged and cannot operate normally, the processing module 16 will turn off the power of the node 10 to execute the node replacement procedure. In step S214, since the number of repairable errors generated by the hardware in the node 10 reaches the preset threshold value (for example, more than 10 repairable errors are generated within one hour), that is, the node 10 is about to be damaged at this time. If it is about to fail to operate normally, the processing module 16 will perform a normal shutdown (shutdown) procedure on the node 10, and execute a node replacement procedure accordingly.

Please refer to FIG. 3 . FIG. 3 is a flowchart of steps of a node replacement program according to an embodiment of the present invention. As shown in FIG. 3 , in step S300 , the processing module 16 sets the node 10 to an initial mode. In this embodiment, the initial mode is a dynamic host configuration protocol (DHCP) mode. In actual operation, when the processing module 16 determines that the node 10 can be removed from the server system 1, it will automatically set the baseboard management controller of the node 10 back to the DHCP mode to obtain a new set of baseboard management controllers. Internet protocol address (internet protocol address, IP address).

In step S302 , the prompt module 14 generates a set of second prompt signals, and the second prompt signals are used to indicate that the node 10 can be disconnected from the server system 1 . In step S304 , the detection module 12 detects whether the node 10 is disconnected from the server system 1 . If the detection module 12 detects that the node 10 has not been disconnected from the server system 1 , continue to execute step S304 ; if the detection module 12 detects that the node 10 is disconnected from the server system 1 , then execute step S306 . In step S306 , the detection module 12 will continue to detect whether the node 10 or another group of nodes is plugged into the server system 1 . If the detection module 12 detects that a group of nodes (node 10 or another group of nodes) is inserted into the server system 1, then execute step S308; if the detection module 12 detects that no node has been inserted into the server system 1, then continue to execute step S306. In step S308, the prompting module 14 generates a first prompting signal, and continues to execute step S202.

Please refer to FIG. 4 . FIG. 4 is a detailed flow chart of steps according to step S304 in FIG. 3 . As shown in FIG. 4 , after the prompting module 14 generates the second prompting signal (ie, step S302 ), the timing module 18 sets a set of first preset times (for example, one minute) and starts timing. In step S402 , it is determined whether the node 10 has been disconnected from the server system 1 . If it is determined that the node 10 has not been disconnected from the server system 1 within the first preset time, then step S404 is performed; if it is determined that the node 10 has been disconnected from the server system 1 and the first preset time has passed, then step S306 is performed. In step S404, the timing module 18 resets the first preset time and restarts the timing, and continues the determination procedure of step S402.

In addition, the step of judging whether the node 10 has been disconnected from the server system 1 performed in step S402 can be achieved by the detection module 12, the processing module 16 or the network interface controller of the node 10, the present invention is not limited here, for example, Check whether the node 10 is disconnected by pinging the NIC of the BMC on the node 10. In this way, the judging mechanism in FIG. 4 can avoid misjudgment that the node 10 has been disconnected from the server system 1 due to network instability or poor contact. In other words, the judging mechanism in FIG. 4 is a de-bounce mechanism .

Please refer to FIG. 5 , which is a detailed flow chart of steps according to step S306 in FIG. 3 . As shown in FIG. 5, after the detection module 12 detects whether the node 10 is disconnected from the server system 1 (i.e. step S304), the timing module 18 will set a set of first preset times and a set of second preset times and Start counting, wherein the second preset time follows the first preset time. For example, the first preset time is the first minute (that is, the 0th to 60th seconds) when the timing module 18 starts timing, and the second preset time is the second minute (that is, the 61st to 60th seconds) when the timing module 18 starts timing. 120 seconds), it should be noted that the first preset time and the second preset time can be different.

In step S502, it is determined whether the node 10 is plugged into the server system 1 or not. If it is determined that the node 10 has not been inserted into the server system 1, then execute step S504; if it is determined that the node 10 is inserted into the server system 1, then execute step S506. In step S504, the timing module 18 resets the first preset time and counts again, and continues the judging process of step S502, so the judging mechanism of steps S502 and S504 is a de-bounce mechanism. In addition, the judgment procedure executed in step S502 can be achieved by the detection module 12, the processing module 16 or the network interface controller of the node 10, the present invention is not limited here, for example, it can be detected by pinging the NIC of the BMC on the node 10 Whether node 10 is inserted.

In step S506, if it is determined that the node 10 is plugged into the server system 1 and the first preset time has elapsed, then it is judged whether the node 10 is still plugged into the server system 1 during the second preset time. If it is judged that the node 10 is still inserted into the server system 1 continuously during the second preset time, it means that the positions of the node 10 and the inserted server system 1 are correct, then the steps after step S308 are executed; Assuming that the server system 1 is pulled out during the time, it means that the position of the node 10 and the inserted server system 1 may be wrong or the wrong node 10 is pulled out, then the steps after step S300 are executed to insert the correct node 10 into the The correct location in the server system 1, so the judging mechanism in step S506 is a fool-proofing mechanism.

In addition, the judgment procedure executed in step S506 can be achieved by the detection module 12, the processing module 16 or the network interface controller of the node 10, the present invention is not limited here, for example, it can be detected by pinging the NIC of the BMC on the node 10 Whether node 10 is continuously inserted. In this way, through the judging mechanism in Figure 5, in addition to avoiding the misjudgment that the node 10 has been inserted into the server system 1 due to network instability or poor contact, it also allows users to have the opportunity to be an error node and have the opportunity to Pull out this node and insert it into a correct node. In other words, the judging mechanism in FIG. 5 is a combination of a de-bounce mechanism and a fool-proofing mechanism.

Based on the above, the server system and node replacement method provided by the embodiments of the present invention judge whether the node or the hardware in the node has been replaced or new by detecting the identification code of the node and the hardware configuration information of the hardware in the node. Whether the node is added, and then selectively execute the node replacement program or install the operating system, software package data or firmware package data on this node, even if the node or hardware is not replaced, it can also force the re-installation of the operating system, Package data or firmware package data. In addition, the server system and node replacement method of the present invention can also continuously detect the hardware status of the node after the node installs the operating system, software package data or firmware package data, and when the hardware in the node generates an error, it can be prompted by a signal Let the user know that the node replacement procedure is available. In this way, the server system and node replacement method of the present invention can automatically execute the processing procedure of whether the node needs to be replaced, and the user only needs to insert or unplug the node from the server system according to the prompt signal, and does not need to do other tests The program is very practical.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.

8. server system as claimed in claim 6, it is characterised in that perform the node in the server system and replace program When, the node sets are an initial pattern by the processing module, and then the reminding module produces one second cue, and this second Cue is indicating that the node can pull away the server system, then carrys out the detection module and detect whether the node pulls away the clothes It is engaged in device system, and continues after detecting that the node pulls away the server system and to detect the node or whether another node inserts this Server system, if the detection module detects that the node or another node insert the server system, reminding module production Raw first cue, and the detection module continue detect first identification code of the node and the hardware this is first hard Processing routine after part configuration information.

9. server system as claimed in claim 8, it is characterised in that the server system also includes a timing module, should Timing module communication connects the detection module, when the detection module detects the node and whether pulls away the server system, the meter When module set and one first preset time and start timing, if the detection module detects the node in first preset time The server system is not pulled away yet, then the timing module resets first preset time and reclocking, if the detection module is examined Measure the node to pull away the server system and have been subjected to first preset time, then continue and detect the node or another node and be The no processing routine inserted after the server system.

10. server system as claimed in claim 8, it is characterised in that the server system also includes：

One timing module, timing module communication connect the detection module, the node or another node are detected in the detection module When whether inserting the server system, the timing module sets one first preset time and one second preset time and starts to count When, after wherein second preset time is connected in first preset time, if the detection module detect the node in this first The server system is not yet inserted in preset time, then the timing module resets first preset time and reclocking, if should Detection module detects that the node inserts the server system and has been subjected to first preset time, then continue detect the node in Whether the server system is still persistently inserted in second preset time, if the detection module detects that the node is second pre- in this If pulling away the server system in the time, then processing routine of the processing module that continues by the node sets for the initial pattern, If the detection module detects the node in not pulling away the server system yet after second preset time, the prompting mould Block produces first cue, and the detection module continue detect first identification code of the node and the hardware this Processing routine after one hardware configuration information.
