Description

Technical Field

[0001] The embodiments of the present application relate to the server field, and in particular to a server cabinet, a circuit control method, and a computing node. Background Art

[0002] With the rapid development of the Internet and computer technology, servers are being used more and more widely. For example, in a cabinet server, multiple computing nodes (server nodes) are placed in a cabinet.

[0003] Compute nodes are equipped with a baseboard management controller (BMC). Users can use the BMC to remotely perform operations such as firmware upgrades and device monitoring. In a rack-mounted server, multiple compute nodes access the BMCs through a converged network port on the rack chassis.

[0004] However, the staff of the cabinet server may remove a computing node from the chassis for maintenance. At this time, the computing node will be disconnected from the aggregation network port, and the user cannot access the BMC of the computing node. Summary of the Invention

[0005] The present invention provides a server for enabling a computing node to access its own baseboard management controller when the computing node is started outside the server chassis. The present invention also provides a corresponding circuit control method, computing device, computer-readable storage medium, and computer program product.

[0006] A first aspect of the present application provides a server cabinet, which includes a computing node, a first circuit board, a switching circuit and a controller, wherein the computing node is provided with a baseboard management controller and a network interface; the first circuit board is provided with a switching module; the switching circuit is connected to the baseboard management controller, the network interface and the switching module respectively, the switching circuit is used to connect the network interface and the baseboard management controller to form a first path, and the switching circuit is also used to connect the network interface and the switching module to form a second path, the first path is used for accessing the baseboard control manager of the computing node, and the second path is used for accessing the baseboard control manager of the computing node connected to the switching module; the controller is connected to the switching circuit, and the controller is used to control the switching circuit to connect the first path when the startup position of the computing node is outside the server frame of the server cabinet.

[0007] The computing node in this application is a computing node, and the switching module can be specifically a switching chip, which is arranged on a first circuit board. The first circuit board is specifically a fan backplane, and the fan backplane is arranged on a server frame of a server cabinet. The switching module can be connected to the computing node through the internal cables of the first circuit board or the printed circuit board wiring.

[0008] The network interface in this application is specifically an RJ45 interface. The network interface can also be understood as an external switch connected to a network cable. The computing node is connected to the network through the network interface. The user can access the network through the client to access the network interface, thereby accessing the computing node and the baseboard management controller of the computing node.

[0009] In this application, when the staff places the computing node in the slot of the server cabinet and powers it on, it can be understood that the startup position of the computing node is inside the frame of the server frame. When the staff takes the computing node out of the slot of the server cabinet and powers it on, it can be understood that the startup position of the computing node is outside the frame of the server frame.

[0010] In the present application, when a computing node is started outside a server chassis, the controller controls the switching circuit to conduct a first path. At this time, the network interface of the computing node is used to access the baseboard management controller of the computing node.

[0011] In the first aspect, the switching circuit is used to connect the network interface and the baseboard management controller to form a first path, and the switching circuit is also used to connect the network interface and the switching module to form a second path. The controller is used to control the switching circuit to connect the first path when the startup position of the computing node is outside the frame of the server frame of the server cabinet, so that when the computing node is started outside the frame of the server frame, the computing node can also access its own baseboard management controller.

[0012] In a possible implementation of the first aspect, there are multiple computing nodes, and the switching module is used to access the baseboard management controllers of the multiple computing nodes. The controller is also used to control the switching circuit to turn on the second path when the startup position of the computing node is within the frame of the server machine frame.

[0013] In this possible implementation, the server cabinet includes multiple computing nodes, and a baseboard management controller can be set in each of the multiple computing nodes. When the computing node is started in the frame of the server frame, the controller controls the switching circuit to conduct the second path. At this time, the network interface of the computing node is used to access the baseboard management controllers of multiple computing nodes through the switching module, thereby realizing flexible control of the conductive path according to the startup position of the computing node and access to the baseboard management controllers of different computing nodes.

[0014] In a possible implementation of the first aspect, a detection port is provided on the computing node, the controller is connected to the detection port, and the controller is configured to detect a level signal of the detection port to determine a startup position of the computing node.

[0015] In this possible implementation, a detection port is provided on the computing node, and the startup position of the computing node is determined based on the level signal of the controller to the detection port, thereby improving the feasibility of the solution.

[0016] In a possible implementation of the first aspect, the first circuit board is set on the server frame. When the startup position of the computing node is outside the frame of the server frame, the level signal of the detection port is high. When the startup position of the computing node is inside the frame of the server frame, the detection port is connected to the first circuit board, and the level signal of the detection port is low.

[0017] In this possible implementation, when the startup position of the computing node is outside the frame of the server frame, the detection port can be connected to the pull-up resistor in the computing node. At this time, the controller detects that the level signal of the detection port is high. When the startup position of the computing node is inside the frame of the server frame, that is, when the computing node is inserted into the server frame as a computing node, the detection port will be connected to the first circuit board through a connector or other components. At this time, the first circuit board (that is, the fan backplane) will ground the detection port. At this time, the controller detects that the level signal of the detection port is low, which improves the feasibility of the solution.

[0018] In a possible implementation manner of the first aspect, the controller is a programmable logic device, and the detection port is a general input and output port.

[0019] In this possible implementation, the controller is a programmable logic device and the detection port is a general input and output port, which improves the feasibility of the solution.

[0020] In a possible implementation of the first aspect, the switching circuit includes a first selection switch and a second selection switch, one end of the first selection switch is connected to the network interface, one end of the second selection switch is connected to the baseboard management controller, the other end of the first selection switch is used to close to the first endpoint or the third endpoint, and the other end of the second selection switch is used to close to the second endpoint or the fourth endpoint, the first endpoint is connected to the second endpoint, the third endpoint is connected to the switching module, and the fourth endpoint is connected to the switching module; when the first selection switch is closed to the first endpoint and the second selection switch is closed to the second endpoint, the first path is conductive, and when the first selection switch is closed to the third endpoint and the second selection switch is closed to the fourth endpoint, the second path is conductive.

[0021] In this possible implementation, when the controller controls the switching circuit to conduct the first path, the switching circuit can control the first selection switch to close to the first endpoint and control the second selection switch to close to the second endpoint. When the controller controls the switching circuit to conduct the second path, the switching circuit can control the first selection switch to close to the third endpoint and control the second selection switch to close to the fourth endpoint, thereby improving the feasibility of the solution.

[0022] In a possible implementation manner of the first aspect, the switching circuit and the controller are provided on a computing node.

[0023] In this possible implementation, the switching circuit and the controller are set on the computing node, thereby realizing the small-scale integration of the server.

[0040] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present application, rather than all the embodiments. Those skilled in the art will appreciate that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0042] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0043] In addition, numerous specific details are provided in the detailed description below to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0044] Embodiments of the present application provide a server cabinet for ensuring that computing nodes can access their own baseboard management controllers. Embodiments of the present application also provide corresponding circuit control methods, computing nodes, storage media, and other related devices. These are described in detail below.

[0045] The following examples illustrate the application scenarios involved in the embodiments of the present application.

[0046] like Figure 1 As shown, a plurality of computing nodes 101 are provided in the cabinet server. Each computing node 101 is provided with a baseboard management controller (BMC). Users can perform some remote operations such as firmware upgrade and machine equipment viewing on the computing node 101 through the BMC.

[0047] In order to facilitate the management of cabinet servers and reduce the number of interfaces, a converged network port 103 and a switching module 104 are set on the server frame 102 of the server cabinet, for example, on the fan backplane of the server frame 102. Each node server 101 can communicate with the switching module 104 by accessing the converged network port 103. The switching module 104 can realize functions similar to a switch, thereby enabling each node server 101 to access the BMC of each other.

[0048] However, the network cables of the aggregation network port 103 are all located on the server frame 102. When the staff of the cabinet server takes a computing node 101 out of the server frame 102 for maintenance, the computing node 101 will be disconnected from the aggregation network port 103, resulting in the user being unable to access the BMC of the computing node 101.

[0049] The server cabinet and circuit control method provided in the embodiments of the present application are described below in conjunction with the above application scenarios.

[0050] like Figure 2 As shown, an embodiment of the circuit control method provided in the embodiment of the present application includes:

[0051] 201. Determine whether the startup location of the computing node is outside the server chassis.

[0052] like Figure 3As shown, the circuit control method provided in the embodiment of the present application is applied to a controller 311, and the controller 311 is set on a server cabinet. The server cabinet also includes a computing node 310, a first circuit board 320 and a switching circuit 312. The computing node 310 is provided with a baseboard management controller 313 and a network interface 314. The first circuit board 320 is provided with a switching module 321. The switching circuit 312 is respectively connected to the baseboard management controller 313, the network interface 314 and the switching module 321. The switching circuit 312 is used to connect the network interface 314 and the baseboard management controller 313 to form a first path. The switching circuit 312 is also used to connect the network interface 314 and the switching module 321 to form a second path. The first path is used for accessing the baseboard control manager 313 of the computing node 310, and the second path is used for accessing the baseboard control manager of the computing node connected to the switching module 321. The controller 311 is also electrically connected to the switching circuit 312.

[0053] Among them, the server cabinet includes multiple computing nodes 310, each of the multiple computing nodes 310 can be provided with a baseboard management controller 313, or can also not be provided with a baseboard management controller 313, the switching module 321 can specifically be a switching chip, which is set on the first circuit board 320, the first circuit board 320 is specifically a fan backplane, and the fan backplane is set on the server frame of the server cabinet, and the switching module 321 is connected to the computing node 310 through the internal cables of the first circuit board 320 or the printed circuit board (PCB) routing.

[0054] Furthermore, a network interface 314 is also provided on the computing node 310. The network interface 314 is specifically an RJ45 interface. The network interface 314 can also be understood as an external switch connected to a network cable. The computing node 310 is connected to the network through the network interface 314. The user can access the network through the client to access the network interface 314, thereby accessing the computing node 310 and the BMC of the computing node 310.

[0055] Furthermore, computing node 310 is also provided with a controller 311 and a detection port 315. Controller 311 is connected to detection port 315. When computing node 310 is started, controller 311 detects the level signal of detection port 315 to determine the startup position of computing node 310. The startup position includes inside the server chassis and outside the server chassis. Controller 311 is a complex programmable logic device (CPLD), and detection port 315 is a general-purpose input / output (GPIO) port. Detection port 315 can also be understood as a pin on computing node 310. When a staff member places computing node 310 in a slot of a server cabinet and powers it on, computing node 310 can be understood as being in the server chassis. When a staff member removes computing node 310 from the slot of the server cabinet and powers it on, computing node 310 can be understood as being in the server chassis.

[0056] Specifically, the first circuit board 320 is set on the server frame. When the startup position of the computing node 310 is outside the frame of the server frame, the detection port 315 can be connected to the pull-up resistor in the computing node 310. At this time, the controller 311 detects that the level signal of the detection port 315 is high. When the startup position of the computing node 310 is inside the frame of the server frame, that is, when the computing node 310 is inserted into the server frame (the slot of the server cabinet), the detection port 315 will be connected to the first circuit board 320 through a connector or other components. At this time, the first circuit board 320 (that is, the fan backplane) grounds the detection port 315. At this time, the controller 311 detects that the level signal of the detection port 315 is low.

[0057] When determining whether the startup position of the computing node 310 is outside the frame of the server frame, the detection port 315 is detected by the controller 311. When the computing node 310 is started outside the frame of the server frame, the controller 311 detects that the level signal of the detection port 315 is high. When the computing node 310 is started inside the frame of the server frame, the controller 311 detects that the level signal of the detection port 315 is low.

[0058] It should be understood that the startup position of the computing node 310 can also be determined by other methods, and the embodiment of the present application does not limit this.

[0059] 202. Control the switching circuit to conduct the first path.

[0060] When the computing node 310 is started outside the server chassis, the controller 311 controls the switching circuit 312 to turn on the first path. At this time, the network interface 314 of the computing node 310 is used to access the baseboard management controller 313 of the computing node 310 .

[0061] When the controller 311 determines that the startup location of the computing node 310 is outside the server frame, the controller 311 controls the switching circuit 312 to turn on the first path, so that the network interface 314 in the computing node 310 is connected to the baseboard management controller 313 of the computing node 310 through the first path of the switching circuit 312, that is, the user can access the BMC of the computing node 310 through the network interface 314.

[0062] 203. Control the switching circuit to conduct the second path.

[0063] When the computing node 310 is started in the server chassis, the controller 311 controls the switching circuit 312 to conduct the second path. At this time, the network interface 314 of the computing node 310 is used to access the baseboard management controllers of multiple computing nodes through the switching module 321 .

[0064] When the controller 311 determines that the startup location of the computing node 310 is within the frame of the server machine frame, the controller 311 controls the switching circuit 312 to conduct the second path, wherein the second path is connected to the switching module 321, so that the network interface 314 of the computing node 310 is connected to the switching module 321 through the second path to access the baseboard management controllers of multiple computing nodes. That is, the user can access the switching module 321 through the network interface 314 of the computing node 310, and access the baseboard management controller 313 of the computing node 310 through the switch function of the switching module 321, and can also access the BMCs of other computing nodes through the switch function of the switching module 321.

[0065] Specifically, the switching circuit 312 includes a first selection switch and a second selection switch, wherein one end of the first selection switch is connected to the network interface, one end of the second selection switch is connected to the baseboard management controller, the other end of the first selection switch is used to close to the first endpoint or the third endpoint, and the other end of the second selection switch is used to close to the second endpoint or the fourth endpoint. The first endpoint is connected to the second endpoint, the third endpoint is connected to the switching module, and the fourth endpoint is connected to the switching module. When the first selection switch is closed to the first endpoint and the second selection switch is closed to the second endpoint, the first path is connected. When the first selection switch is closed to the third endpoint and the second selection switch is closed to the fourth endpoint, the second path is connected.

[0066] When a user needs to access the BMC of the computing node 310, the computing node 310 is connected through the network interface 314 and connected to the first selection switch (located at Figure 3 The switching circuit 312 is used to respond to the command sent by the controller 311 to select the first path or the second path. When the first path is selected, the first selection switch of the upper switching circuit 312 is closed to the first endpoint, thereby passing through the second selection switch of the lower switching circuit 312, and the second selection switch is closed to the second endpoint, thereby accessing the media access control layer chip (MAC) and accessing the baseboard control manager 313. When the second path is selected, the first selection switch of the switching circuit 312 is closed to the third endpoint, thereby accessing the switching module 321 through the PHY chip. The switching module 321 is connected to the BMCs of all computing nodes in the server cabinet (except the computing nodes started outside the frame), that is, the user can access the BMCs of these computing nodes, and return to the second selection switch of the switching circuit 312 (located at Figure 3 The second selection switch is closed to the fourth terminal, thereby accessing the baseboard control manager 313 through the MAC chip. It should be understood that the server cabinet includes multiple computing nodes. The above embodiment only uses computing node 310 as an example. The specific implementation of other computing nodes can refer to computing node 310 and will not be repeated in this embodiment.

[0067] like Figure 4 As shown, the embodiment of the present application takes two computing nodes (server nodes) as an example, that is, the server cabinet includes a first node 410 and a second node 420, the first node 410 and the second node 420 are both computing nodes, and the first node 410 and the second node 420 are both provided with a baseboard management controller. Specifically, the first node 410 includes a first controller 411, a first switching circuit 412, and a first baseboard control manager 413, and the second node 420 includes a second controller 421, a second switching circuit 422 and a second baseboard control manager 423, and the switching module 431 in the first circuit board 430 is connected to the first node 410 and the second node 420.

[0068] For example, first node 410 is started within the server chassis, i.e., first node 410 is powered on within the server chassis, and second node 420 is started outside the server chassis, i.e., second node 420 is powered on after being removed from the server chassis by a staff member. When a user needs to access the BMCs of first node 410 and second node 420, the user first needs to determine the startup locations of first node 410 and second node 420.

[0069] When the first controller 411 determines that the startup location of the first node 410 is within the server frame 430, the controller 411 controls the switching circuit 412 to conduct the second path, where the second path is connected to the switching module 431, so that when a user accesses the BMC through the first network interface 414 of the first node 410, the user can connect to the switching module 431 through the first path to access the baseboard management controller of at least one computing node, that is, the first node 410 can access the first baseboard control manager 413 of the first node 410 through the switching module 431, and can also access the second baseboard control manager 423 of the second node 423 through the switching module 431.

[0070] When the second controller 421 determines that the startup position of the second node 420 is outside the server frame 430, the second controller 421 controls the switching circuit 422 to turn on the first path, wherein the first path is connected to the second baseboard management controller 423 of the second node 420, so that when the user accesses the BMC through the second network interface 424 of the second node 420, the user can connect to the baseboard management controller 423 of the second node 420 through the second path, that is, the second node 420 can access the baseboard management controller 423 of the second node 420 at this time.

[0071] For example, when the first node 410 and the second node 420 are both started within the server frame, the user can access the first substrate control manager 413 of the first node 410 through the first network interface 414 of the first node 410, or access the second substrate control manager 423 of the second node 420 through the first network interface 414 of the first node 410, or the user can access the first substrate control manager 413 of the first node 410 through the second network interface 424 of the second node 420, or access the second substrate control manager 423 of the second node 420 through the second network interface 424 of the second node 420.

[0072] Exemplarily, when the first node 410 and the second node 420 are not started within the frame of the server frame, the user can access the first baseboard control manager 413 of the first node 410 through the first network interface 414 of the first node 410, or the user can access the second baseboard control manager 423 of the second node 420 through the second network interface 424 of the second node 420.
