Contents of the invention

The present application provides a method for port sharing. The method switches the mode of the shared port by setting the shared port in the server box, thereby providing the functions of different ports. Since there is no need to set corresponding ports on the computing nodes, the cost of the computing nodes is saved. The panel space can meet the needs of the increasing number and variety of ports. The present application also provides devices, devices, computer-readable storage media, and computer program products corresponding to the above methods.

In a first aspect, the present application provides a port sharing method. The method is performed by a multi-node server. A multi-node server, also known as a high-density server, is a high-density server in which multiple computing nodes are set in a server frame. Wherein, the server box includes at least one shared port, and the shared port is an N-in-one port, where N is greater than 1. For example, N may take a value of 4. Shared ports are used to provide different port functions by mode.

Specifically, the multi-node server may receive a mode switching instruction, the mode switching instruction is used to switch the mode of the shared port, and then the multi-node server switches the shared port to a specified working mode according to the mode switching instruction. Wherein, the designated working mode is a mode in which the shared port provides designated functions.

In this method, by reintegrating the panel space, the shared port that provides different port functions according to the mode is set on the panel of the server frame. By switching the mode of the shared port, for example, switching to the specified working mode, the shared port can provide the corresponding port function corresponding to the specified working mode. Specifies the function. In this way, the panel space of computing nodes can be saved, and the panel space can be reserved for upgrading the specifications of multi-node servers, so as to meet the demands of increasing port quantity and port types.

In some possible implementation manners, the multi-node server may share ports of different nodes (for example, ports of the same type on different nodes). That is, the shared port can provide port functions to different computing nodes according to the mode. For ease of description, this application refers to the above-mentioned shared port as the first shared port. The first shared port may be any port in the at least one shared port.

The port switches to the first working mode. Wherein, the first working mode is a mode in which the first shared port is used by a designated computing node among the plurality of computing nodes and provides port functions for the designated computing node.

The method realizes the interaction with different computing nodes through the first shared port, for example, the operation and maintenance of different computing nodes can be realized based on the first shared port, thereby saving panel space and improving port utilization.

In some possible implementations, before receiving the first mode switching instruction, the multi-node server may also receive a state switching instruction for the first shared port, and then switch the first shared port to The state is switched to the operation and maintenance state. Wherein, the operation and maintenance state is used to identify the first shared port to transmit operation and maintenance information, so as to perform operation and maintenance on the multi-node server.

In this way, the multi-node server can realize time-sharing operation and maintenance of different computing nodes based on the first shared port, without setting up operation and maintenance ports on the panel of each computing node for operation and maintenance, which saves the panel space of computing nodes and improves The utilization rate of the first shared port.

Specifically, the multi-node server receives a second mode switching instruction, and the second mode switching instruction is used to switch the mode of the second shared port, and then the multi-node server switches the second shared port to the The port switches to the second working mode. Wherein, the second working mode is a mode in which the second shared port provides a specified type of port function for at least one computing node among the plurality of computing nodes. Taking the second shared port whose physical form is RJ45 as an example, the second shared port can respectively provide functions of a serial port or a network port through mode switching.

Detailed ways

For ease of description, some technical terms involved in the embodiments of the present application are firstly introduced.

A multi-node server, also called a high-density server, refers to a server that includes multiple computing nodes in a single server box. Due to its powerful computing power, ultra-high storage density, and easy management and maintenance, multi-node servers are widely used in various business scenarios such as cloud computing and high-performance computing. For example, a multi-node server can be used to build an information technology (information technology, IT) infrastructure of a cloud data center. Wherein, the server frame is also referred to as a chassis, and the computing node may be a plug-in server that can be inserted into the server frame, and the plug-in server may be, for example, a blade server or a rack server.

A port refers to the outlet for communication between a computer and other equipment (such as the multi-node server mentioned above) and the outside world. In the field of hardware, a port may also be called an interface, and some typical examples of ports include USB ports or serial ports. Ports can be divided into different types based on the different functions they implement. For example, some ports are used for operation and maintenance, and some ports are used for power control and user identity (UID) control, and the ports can be divided into different types such as operation and maintenance ports and control ports based on functions.

This application provides a port sharing method. In this method, by reintegrating the panel space, the shared port that provides different port functions according to the mode is set on the panel of the server frame. By switching the mode of the shared port, for example, switching to the specified working mode, the shared port can provide the corresponding port function corresponding to the specified working mode. Specifies the function. In this way, the panel space of computing nodes can be saved, and the panel space can be reserved for upgrading the specifications of multi-node servers, so as to meet the demands of increasing port quantity and port types.

Wherein, the shared port provides different port functions according to modes may include multiple implementation manners. The first implementation manner is that the shared port can provide port functions to different computing nodes according to modes. Specifically, when the shared port is switched to the first working mode, the shared port can be used by a designated computing node among the plurality of computing nodes to provide port functions for the designated computing node. For example, when a multi-node server includes 4 computing nodes, a shared port such as a serial port can provide port functions for computing nodes 1 to 4 through mode switching. A second implementation manner is that the shared port may provide different types of port functions to at least one computing node among the plurality of computing nodes. Specifically, when the shared port is switched to the second working mode, the shared port can provide at least one computing node among the plurality of computing nodes with a specified type of port function. For example, a shared port in the physical form of RJ45 can provide functions of a serial port or a network port respectively through mode switching.

In order to facilitate the distinction, in the embodiment of the present application, the shared port that can be used by different computing nodes in time sharing to provide port functions for different computing nodes is called the first shared port, which will provide different types of ports for at least one computing node among multiple computing nodes. The shared port that functions as the first port is called the second shared port. The solution provided by the present application will be described in detail below in conjunction with the accompanying drawings.

In a multi-node server, ports can usually be deployed on the panel of the computing node or the panel of the server box. A panel is an interface for interaction on the shell of a compute node or server box. Referring to the schematic diagram of the panel of the multi-node server shown in FIG. 1 , as shown in FIG. 1 , the multi-node server 100 includes a plurality of computing nodes 10 and a server box 20 . FIG. 1 uses a multi-node server 100 as an example to illustrate with 4 servers of computing nodes 10 arranged in a server frame 20 with a height of 2 units, that is, a 2U4 server. Wherein, U is a unit representing the external size of the server (such as the multi-node server 100 ), and U is an abbreviation of unit. Among them, the external dimensions are usually characterized by width and height, for example, the width is 48.26cm, that is, 19 inches, and the height is a multiple of 4.445cm. Since the width is 19 inches, the server frame 20 is also sometimes referred to as a "19-inch rack". The basic unit of height is 4.445cm. 1U is 4.445cm, and 2U is 2 times of 1U, which is 8.89cm. (A) in FIG. 1 shows the rear panel of the multi-node server 100 , and (B) in FIG. 1 shows the front panel of the above-mentioned multi-node server 100 .

As shown in (A) of FIG. 1 , the rear panel of the multi-node server 100 includes the rear panel 11 of the plurality of computing nodes 10 and the rear panel 21 of the server frame 20 . At least one standard card is deployed on the rear panel 11 of each computing node 10 , where the standard card refers to a standard IO card, that is, an IO card whose parameters (such as electrical parameters and mechanical parameters) conform to standards. For example, the standard card may include different types such as an Ethernet standard card, a high-speed peripheral component interconnect express (PCI-E) standard card, and the like. In this embodiment, two standard cards (standard card 1 and standard card 2 as shown in the figure) are deployed on the rear panel 11 of each computing node 10 for illustration.

The rear panel 11 of each computing node 10 is also equipped with an onboard service port (that is, an onboard service IO port), an operation and maintenance port (that is, an operation and maintenance IO port), a management port, and a control port (that is, a control IO port). The various ports are described below.

The operation and maintenance port refers to a port used for operation and maintenance of the computing node 10 . The operation and maintenance port may include a video graphics array (Video Graphics Array, VGA) and a serial port (serial port). A serial port can also be called a serial interface, a serial communication port (cluster communication port, COM), or a serial port. The serial port can usually be a 9-pin, 4-pin or 25-pin interface with a maximum rate of 115200 bits per second (bit per second, bps), and is usually used to connect a mouse and a communication device (such as an external modem). Serial ports can be divided into different types such as RS-232-C, RS-422, RS485, and USB according to electrical standards and protocols. RS-232-C is also called a standard serial port, and the standard serial port is specifically a 9-pin D-shaped interface. RS-422 is a balanced communication interface that increases the transmission rate and transmission distance, and allows multiple receivers to be connected on a balanced bus. RS-485 is a balanced communication interface. RS-485 adds multi-point and two-way communication capabilities on the basis of RS-422, that is, it allows multiple transmitters to be connected to the same bus, and at the same time increases the drive capability and Conflict protection features, extending the common mode range of the bus. USB is a four-pin interface, with two pins in the middle for data transfer and two pins on the edge for powering peripherals.

The control port is a port for realizing a control function, for example, may include a button and a corresponding indicator light for realizing the control function. The management port is a port for implementing management functions. For example, a user can remotely manage the computing nodes 10 in the multi-node server 100 through the management port. The onboard service port refers to a service-related port integrated in the mainboard. In addition, two power supplies are deployed on the rear panel 11 of the computing node 10 for supplying power to the computing node 10 .

As shown in (B) of FIG. 1 , the front panel of the multi-node server 100 includes the front panel 12 of the plurality of computing nodes 10 and the front panel 22 of the server frame 20 . Wherein, the front panel 12 of each computing node 10 is equipped with storage media, for example, six 2.5-inch hard disks. The front panel 21 of the server frame 20 includes the control components of the plurality of computing nodes 10 and the fixed components of the server frame 20.

In the example of FIG. 1 , the panel space of the computing node 10 is relatively crowded. In order to save the panel space of the computing node 10 and improve the utilization rate of the panel space of the computing node 10, the present application sets a shared port on the server frame 20, and multiple The panel of the computing node 10 is used to set area reservations for corresponding ports, so as to meet the requirements of increasing port numbers and port types.

Referring to the schematic diagram of the port structure of the multi-node server 100 shown in FIG. 2 , as shown in FIG. 2 , the multi-node server 100 includes a plurality of computing nodes 10 and a server box 20 . Wherein, the server frame 20 includes at least one shared port, such as a first shared port 23 and a second shared port 24 . The first shared port 23 and the second shared port 24 may be respectively disposed on a panel of the server frame 20, for example, disposed on a rear panel of the server frame.

Each shared port in the server chassis 20 may include multiple working modes. Regarding the first shared port 23 , when each working mode is enabled, one computing node 10 in the multi-node server 100 can provide an interface for communicating with external devices of the multi-node server 100 through the first shared port 23 . For the second shared port 24, when each working mode is enabled, the second shared port 24 provides a type of port function.

Specifically, the first shared port 23 can be switched to the first working mode. The first working mode is a mode in which the first shared port 23 is used by a designated computing node among the plurality of computing nodes 10 and provides a port function for the designated computing node. The second shared port 24 can be switched to the second working mode. In the second working mode, the second shared port 24 provides a specified type of port function for at least one computing node 10 among the plurality of computing nodes 10 . The port function of the specified type can be a serial port or a network port. Wherein, the network port may include a Gigabit Ethernet port (gigabit ethernet, GE) or a 10GE network port.

In some possible implementation manners, the server frame 20 may further include a switching circuit 25 . The switching circuit 25 receives a first mode switching instruction for the first shared port 23, and the switching circuit 25 can switch the first shared port 23 to the first working mode according to the first mode switching instruction. Similarly, the switching circuit 25 receives a second mode switching instruction for the second shared port 24, and the switching circuit 25 can switch the second shared port 24 to the second working mode according to the second mode switching instruction.

It should be noted that the first shared port 23 may be an operation and maintenance port. Based on this, before receiving the first mode switching instruction for the first shared port 23, the switching circuit 25 may also receive a state switching instruction for the first shared port, and then according to the state switching instruction, switch the The state of the first shared port 23 is switched to the operation and maintenance state. Wherein, the operation and maintenance status is used to identify the first shared port to transmit operation and maintenance information, so as to perform operation and maintenance on the multi-node server 100 .

In the above embodiments, the mode switching commands such as the first mode switching command and the second mode switching command may be triggered by at least one of hardware buttons, software assignment or timing triggers. Wherein, the hardware button may include a hardware button corresponding to each working mode, or may be a hardware button shared by multiple working modes, that is, a shared button. The sharing button includes multiple key modes, such as short press, long press, or double press. When the hardware button is a shared button, you can switch between different working modes through operations such as short press, long press, or double press. In this way, panel space can be further saved, which is conducive to improving product specifications. Of course, it is also possible to assign different values by software to realize the switching of different working modes, or to set a timer and use the timer to count the time to switch to the working mode corresponding to the time period at different time periods.

For ease of understanding, the following uses a hardware button to trigger different mode switching as an example.

Referring to the schematic diagram of the rear panel of the multi-node server 100 shown in FIG. 3 , the first shared port 23 and the second shared port 24 are deployed on the right mounting ear of the panel (for example, the rear panel) of the service box 20 . In this example, the first shared port 23 may be a VGA port, and the second shared port 24 may be a serial port. A hardware button 26 is deployed on the left mounting ear of the panel of the service box 20, and the hardware button 26 is used to switch nodes, so that the first shared port 23 is used by different computing nodes in time-sharing.

For example, the default node can be set as node 1, which is N1 in FIG. 3 . Correspondingly, the first shared port 23 is used by N1 by default. When the user presses the hardware button 26 for a long time, it can be switched to N2, and the first shared port 23 is used by N2. When the user short presses the hardware button 26, it can be switched to N3, and the first shared port 23 is used by N3. When the user double-clicks (for example, presses twice consecutively) the hardware button 26, it can be switched to N4, and the first shared port 23 is used by N4.

Wherein, an indicator light combination 29 is arranged on the left hanging ear of the panel of the service box 20, and the indicator light combination includes an indicator light with the word "KVM". The indicator light with the word "KVM" is used to indicate the node to which the first shared port 23 is currently connected. For example, when the first shared port 23 is connected to N2, the "KVM" indicator corresponding to N2 is on, and the "KVM" indicator lights corresponding to N1, N3 and N4 are off.

Combinations 29 of indications and the like may also include a health light and a UID light. The health lights of each node (such as the light in the shape of an electrocardiogram in FIG. 3 ) are used to indicate the health status of each node. In some embodiments, the health lights can indicate different health states of the nodes by being on and off, and in other embodiments, the health lights can indicate different health states of the nodes by different colors, for example, green and red.

The UID light of each node is used to identify the node. Wherein, the UID light is usually used in conjunction with the hardware button 27 . The hardware button 27 is a UID button. When the UID button is triggered, the UID light corresponding to the node currently connected to the first shared port 23 can be lighted, so that the currently connected node can be quickly determined through the UID light, which is beneficial to the operation and maintenance personnel. Operation and maintenance work.

A hardware button 28 is also disposed on the left hanging ear in the panel of the server frame 20 . The hardware button is 28 power buttons, and the power button can be shared by multiple computing nodes such as N1 to N4. Specifically, when the power button is triggered, the power can be started to supply power to multiple computing nodes 10 . In addition, the power button can also integrate a power indicator light, which can light up when the power supply is turned on to supply power to multiple computing nodes.

In some possible implementation manners, other hardware buttons (not shown in FIG. 3 ) may also be deployed on the panel of the server frame 20 for switching modes for the second shared port 24 . Similar to the hardware button 26, the hardware button can also switch modes by long press, short press, etc., so as to switch the second shared port 24 to a different type of port. For example, the second shared port is COM by default. When the user presses the hardware button for a long time, the second shared port is switched to the GE network port, and when the user presses the hardware button for a short time, it is switched back to COM.

In the above embodiment, the different types of port functions provided by the type of the second shared port 24 may be predetermined according to one or more of the use frequency, importance and speed of each type of port. For example, before leaving the factory, the multi-node server 100 may integrate multiple types of port functions that are less frequently used into one port, so as to realize different types of port sharing. For another example, before leaving the factory, the multi-node server 100 may integrate multiple types of ports of lower importance into one port, so as to realize different types of port sharing.

It should also be noted that during operation and maintenance, the user can also trigger a state switching operation for the first shared port 23 , for example, the state switching operation can be triggered through the hardware button 26 . The hardware button 26 may generate a state switching instruction for the first shared port 23 in response to the state switching operation. Correspondingly, the switching circuit 25 can switch the state of the first shared port 23 to the operation and maintenance state according to the above state switching instruction. When the first shared port 23 has no operation and no data transmission within a preset time period, the first shared port 23 may automatically exit the operation and maintenance state. In some embodiments, the first shared port 23 may also exit the operation and maintenance state based on a user-triggered exit operation and maintenance operation.

This method can effectively save the panel space of the computing node 10 by setting the shared port on the panel of the server frame 20 to be shared by multiple computing nodes such as N1 to N4, or sharing multiple types of ports. After the shared port is set in the server frame 20, the panel of the computing node may reserve an area, which is the free area of the panel of the computing node. Air outlets, power supplies, or non-shared ports can be set in the free area of the panel of each computing node, so as to improve heat dissipation, increase power supply specifications, or increase port specifications.

Referring to the schematic diagram of the rear panel of the multi-node server 100 shown in FIG. 4, (A) in FIG. As shown in the grid shape in the figure), this can increase the air outlet area, thereby improving the ventilation and cooling capabilities of the multi-node server 100, and improving the energy efficiency of the multi-node server 100.

Referring to the schematic diagram of the rear panel of the multi-node server 100 shown in FIG. 5, the panel space (A) in FIG. and the power supply 4, so that the specification of the power supply of the multi-node server 100 can be improved, thereby improving the power supply capability.

It should be noted that the panel space saved by computing nodes in the multi-node server 100 can also be used to deploy non-shared ports, such as some non-shared service ports, so that the port specifications of the multi-node server 100 can be improved to meet the increasing number of ports and port type requirements to improve the performance of the multi-node server 100 .

In the embodiment shown in FIG. 2 , the multi-node server 100 can switch the shared port to a different mode through a mode switching instruction, without the need to switch by cable plugging, thereby improving the ease of maintenance of the multi-node server 100 sex. In addition, the first shared port 23 and the unshared port 1 of the computing node 10 are connected to the first port controller 13 , and the second shared port 24 and the unshared port 2 of the computing node 10 are connected to the second port controller 14 . When the shared port and the non-shared port are set on different sides, it can also meet the requirements of multi-side operation and maintenance.

In the embodiment shown in FIG. 2 , the switching circuit 25 of the multi-node server 100 is used to switch the loop connected to the shared port, so as to be used by different computing nodes 10, or to be used by at least one computing node among the multiple computing nodes 10 10 provides different types of port functions. Wherein, the switch circuit 25 may include at least one of a switch and a switch, and the switch or switch is used to connect the shared port on the server frame 20, and connect the platform control on the motherboard of the computing node 10 in the multi-node server 100 At least one of a platform controller hub (PCH) chip, a baseboard management controller (BMC) and a complex programmable logic device (complex programmable logic device, CPLD).

Referring specifically to the schematic diagram of the switching circuit shown in FIG. 6 , in this example, the switching circuit includes a switch and a switch, and the switch may be a multi-way switch, such as a multi-pole multi-throw switch. Among them, the bus physical channel of the switch is usually fully connected, and the switch can realize the switching of the shared port through software. The bus physical channel of the switch is time-sharingly connected, and the switching of the shared port is realized through the control signal. Wherein, the network port or other high-speed ports can be switched by a switch. The low-speed port can be connected to different bus physical channels by switching the switch, so as to realize the switching of the low-speed shared port.

Specifically, the switching circuit can be connected to a plurality of computing nodes 10 such as N1 to N4, and at least one of the platform controller center PCH, BMC and CPLD is arranged on the motherboard of each computing node 10 . Among them, the PCH is used to connect to a type A port such as a USB port, the BMC is used to connect to a type B port such as a VGA, and the CPLD is used to connect to a button such as a power button and a UID button.

The above-mentioned A-type port and B-type port can be set on the panel of the server frame in the form of a shared port, and the PCH and BMC can be connected to the shared port through a switching circuit, and then the switching circuit can perform mode switching according to a mode switching command (such as a switching signal) , thereby switching the shared port. Taking the switching network port as an example, the switch in the switching circuit is physically connected to N1 to N4. When the user needs to operate and maintain N1, he can only forward data packets to N1 through software settings, so as to realize the operation and maintenance of N1. .

Similarly, some buttons such as power button, UID button or node switch button can also be set on the panel of the server box in the form of shared buttons, and the CPLD can be connected to the shared button through a switching circuit to switch modes. Wherein, the power button and the UID button can be directly connected to the switching circuit, and the node switching button can be connected to the switching circuit through the controller. Wherein, the switching circuit and the controller can be deployed on the circuit board inside the frame.

When the panel space of N1 to N4 is relatively sufficient, Type A ports and/or Type B ports can also be set on the panels of N1 to N4, and users can use the shared ports on the panels of the server box 20 or the panels of N1 to N4 The set A-type ports and B-type ports execute related operations, which is not limited in this embodiment. In some embodiments, no type A port and/or type B port may be provided on the panels of N1 to N4, for example, more power supply or service ports may be provided, so that the power supply specification or port specification may be improved.

It should be noted that FIG. 6 is only a schematic implementation manner of a switching circuit, and in other possible implementation manners of the embodiment of the present application, the switching circuit may also include only a switching switch, or only a switch. Similarly, the switch circuit can also connect the shared port with the PCH, BMC, and CPLD in other ways.

The structure of the multi-node server 100 is introduced above, and next, the port sharing method provided by the embodiment of the present application is introduced.

Referring to the flow chart of the port sharing method shown in Figure 7, the method includes:

S702: The multi-node server 100 receives a state switching instruction for the first shared port 23 .

The state switching instruction is used to switch the state of the port (for example, the first shared port 23 ). The state of the port may include an operation and maintenance state and a non-operation and maintenance state. Based on this, the state switching instruction can be used to switch the state of the port from the non-operation and maintenance state to the operation and maintenance state, so as to perform operation and maintenance.

In some possible implementation manners, the above state switching instruction may be triggered by a user. For example, the multi-node server 100 may provide a hardware button for triggering a state switching operation, the user may trigger the state switching operation by operating the hardware button, and the hardware button generates a state switching instruction in response to the state switching operation triggered by the user.

In some other possible implementation manners, the above state switching instruction may also be automatically triggered by the multi-node server 100. For example, the multi-node server 100 may set a trigger condition, and when the trigger condition is met, the state switching instruction is automatically generated.

Wherein, the trigger condition may be a time condition. For example, the trigger condition can be set to switch the port from the non-operation and maintenance state to the operation and maintenance state every N seconds, and keep the operation and maintenance state for M seconds, where M and N are positive integers. It should be noted that during the period of maintaining the operation and maintenance state for M seconds, if the operation and maintenance data or instructions are received, the timing can be stopped, and after the operation and maintenance is completed, the state can be switched back to the non-operation and maintenance state.

Trigger conditions can also be numerical conditions. For example, the multi-node server 100 can run software, such as random number generation software, and the multi-node server 100 can generate a state switching instruction according to the value assigned by the software. For example, when the software value is 1, the multi-node server 100 generates the above state switching instruction.

S704: The multi-node server 100 switches the state of the first shared port 23 to the operation and maintenance state according to the state switching instruction.

Specifically, the multi-node server 100 can enable the operation and maintenance function according to the state switching instruction, so as to switch the state of the first shared port 23 from the non-operation and maintenance state to the operation and maintenance state. Among them, enabling the operation and maintenance function may be to start the operation and maintenance software, open the log system, and so on. The operation and maintenance status is used to identify the first shared port 23 to transmit operation and maintenance information, so as to perform operation and maintenance on the multi-node server 100 .

S706: The multi-node server 100 receives a first mode switching instruction.

The first mode switch instruction refers to an instruction to switch the first shared port 23 to the first working mode. Wherein, the first working mode is a mode in which the first shared port is used by a designated computing node among the plurality of computing nodes 10 and provides a port function for the designated computing node.

Similar to the state switching instruction, the first mode switching instruction can be triggered by the user. For example, the multi-node server 100 may provide a hardware button for triggering a mode switching operation, the user may trigger the mode switching operation by operating the hardware button, and the hardware button generates a first mode switching instruction in response to the mode switching operation triggered by the user.

It should be noted that the first mode switching instruction generated by the hardware button may be different depending on the manner in which the user operates the hardware button. For example, the first shared port is connected to N1 by default, the user can switch to N2 by long pressing the hardware button, short press the hardware button to switch to N3, and double press the hardware button to switch to N4.

In some possible implementation manners, the first mode switching instruction may also be automatically triggered by the multi-node server 100 . For example, the multi-node server 100 may be triggered by software value assignment or timing. For the specific trigger process, please refer to the relevant content description of S702, which will not be repeated here.

S708: The multi-node server 100 switches the first shared port 23 to the first working mode according to the first mode switching instruction.

Specifically, the multi-node server 100 may execute corresponding logic through the switching circuit according to the first mode switching instruction, so as to switch the first shared port 23 to the first working mode. In this way, the first shared port 23 can be connected to the specified computing node, and the operation and maintenance personnel can realize the operation and maintenance of the specified computing node based on the first shared port 23 .

In this embodiment, the multi-node server 100 can realize the time-sharing connection between the first shared port 23 and different computing nodes 10 according to different first mode switching instructions, and then realize the connection between the first shared port 23 and the The corresponding computing nodes 10 perform operation and maintenance. On the one hand, it can meet the operation and maintenance requirements; on the other hand, it increases the frequency of use of the first shared port 23 , avoids waste, saves panel space, and can improve the specifications of the multi-node server 100 .

The above S702 to S704 are optional steps in the embodiment of the present application, and the above S702 to S704 may not be executed to execute the port sharing method of the present application. For example, when the first shared port 23 is not an operation and maintenance port, for example, when the first shared port 23 is a management port or a control port, the multi-node server 100 may not execute the above S702 to S708.

Through the above S706 to S708, the multi-node server 100 implements port sharing among different computing nodes 10 . In some possible implementation manners, the multi-node servers 100 may also share different types of ports. Specifically, before leaving the factory, one or more of the frequency of use, importance and speed of various types of ports may be acquired. Then, according to the frequency of use, importance and rate (such as data transmission rate) of each type of port, set the different types of port functions that need to be shared, and integrate the different types of port functions into the same port, that is, the second shared port twenty four.

Wherein, the different types of port functions may be port functions with low frequency of use, port functions with low importance, or port functions with low rate. It should be noted that ports of different types may have the same physical form and be connected to different types of buses. For example, a port in the physical form of RJ45 may be connected to COM, a Universal Asynchronous Receiver/Transmitter (UART) type bus, or may be connected to a GE or 10GE type bus. Similarly, a port with a physical form of USB Type C can be connected to a USB3.0 or USB2.0 bus, or can be connected to a VGA, high definition multimedia interface (HDMI) or GE type bus.

Based on this, the multi-node server 100 may receive the second mode switching instruction. Wherein, the generation method of the second mode switching instruction may refer to the first mode switching instruction, and will not be listed here. Then the multi-node server 100 can switch the second shared port 24 to the second working mode according to the second mode switching instruction. Specifically, the multi-node server 100 may execute corresponding logic through the switching circuit 25 according to the second mode switching instruction, so as to switch the second shared port 24 to the second working mode.

Wherein, the second working mode is a mode in which the second shared port 24 provides a specified type of port function for at least one computing node 10 among the plurality of computing nodes 10 . The second shared port 24 can be connected to multiple computing nodes 10 , or can be connected to one computing node 10 among the multiple computing nodes 10 , and provides a specified type of port function for the connected computing nodes 10 . In some embodiments, the multi-node server 100 can switch the second shared port 24 from a serial port such as COM or UART to a GE network port or a 10GE network port according to the second mode switching instruction. In other embodiments, the multi-node server 100 may switch the second shared port 24 from USB to VGA, HDMI or Ethernet port according to the second mode switching instruction.

Based on the above description, the embodiments of the present application provide a port sharing method. Specifically, the panel setting of the server frame 20 provides a shared port with different port functions according to the mode, such as the first shared port 23 or the second shared port 24, by switching the mode of the shared port, for example, switching to a specified working mode, you can Make the shared port provide the specified function corresponding to the specified working mode. , thereby saving and improving the utilization rate of the panel space of the computing nodes, and reserving the panel space for upgrading the specifications of the multi-node server 100, which can meet the demands of increasing port quantity and port type services.
