Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments of the present application. Based on the implementation methods of the present application, all other implementation methods that a server manager in the field can obtain without making creative efforts are within the scope of the protection of the present application.
Fig. 1 is a schematic diagram of a portion of a server 100 in some technologies. In fig. 1, a server 100 includes a main board 11, a rear window 12, and a front window 13. Wherein the rear window 12 may also be referred to as a rear panel of the server 100, and the front window 13 may also be referred to as a front panel of the server 100. The rear window 12 and the front window 13 may serve as at least part of the housing of the server 101. The main board 11 is disposed in the housing. The rear window 12 may include a first network interface 121 and the front window 13 may include a second connector 131 and a second network interface 132 connected with the second connector 131. The main board 11 may include, but is not limited to, a baseboard management controller 111, a first network conversion chip 112, a second network conversion chip 113, and a first connector 114. Wherein:
the baseboard management controller 111 may also be referred to as BMC (Baseboard Management Controller) for implementing management functions of the server 100. For example, the BMC may monitor the chip operating temperature in the server 100 and control the fan in the server 100 to rotate to cool the chip if the chip operating temperature exceeds a temperature threshold.
The baseboard management controller 111 may also include a management interface presented to a server manager. The baseboard management controller 111 can output the monitored operation data of the server 100 to a management interface for display, so that a server manager can check the operation condition of the server 100. Meanwhile, the server manager may issue a management instruction for the server 100 to the baseboard management controller 111 through the management interface, so that the baseboard management controller 111 performs control matching with the management instruction on the server 100 based on the received management instruction. For example, the baseboard management controller 111 may display the monitored chip operating temperature through a management interface for a server manager to view. For another example, the server manager may issue a power-down instruction to the server 100 through the management interface, so that the baseboard management controller 111 performs a power-down operation on the server 100 when receiving the power-down instruction.
The first network conversion chip 112 and the second network conversion chip 113 may convert the RGMII signal into the MDI signal. Where the RGMII signal may refer to a signal transmitted over a gigabit media independent interface (Reduced Gigabit Media Independent Interface, RGMII), and the MDI signal refers to a signal transmitted over a media dependent interface (Medium Dependent Interface, MDI). In particular, the first network conversion chip 112 and the second network conversion chip 113 may include PHY chips,
the first connector 114 and the second connector 131 may include MDI connectors. MDI connectors are used to transmit MDI signals. The first network interface 121 and the second network interface 132 may include RJ45 ports for connecting to other network devices outside of the server 100.
Specifically, in fig. 1, the baseboard management controller 111 may include a first port 1111 and a second port 1112. The first port 1111 and the second port 1112 may be RGMII interfaces, and each port binds one MAC address respectively. The first port 1111 may be connected to the first network conversion chip 112. The first network conversion chip 112 is connected to the first network interface 121. In this way, the baseboard management controller 111 may be connected to the first network interface 121 on the rear window 12 through the first port 1111 and the first network conversion chip 112, and the first network conversion chip 112 converts the RGMII signal received from the first port 1111 into the MDI signal and outputs the converted MDI signal through the first network interface 121. Similarly, the second port 1112 may be connected to the second network conversion chip 113. The second network conversion chip 113 is connected to the second network interface 132 through the first connector 114 and the second connector 131. In this way, the baseboard management controller 111 is connected to the second network interface 132 on the front window 33 through the second port 1112, the second network conversion chip 113, the first connector 114, and the second connector 131, and the second network conversion chip 113 converts the RGMII signal received from the second port 1112 into an MDI signal and outputs the converted MDI signal through the second network interface 132.
The first port 1111, the first network conversion chip 112, and the first network interface 121 may form a first network channel; the second port 1112, the second network conversion chip 113, the first connector 114, the second connector 131, and the second network interface 132 may form a second network channel. The baseboard management controller 111 may perform data interaction with external devices through the first network channel or the second network channel. For example, the first network interface 121 may be connected to a display device that is used to present a baseboard management controller 111 management interface. The baseboard management controller 111 may transmit the monitored data to the display device through the first network channel to display the monitored data through the management interface, or the display device may transmit a control instruction issued by the user based on the management interface to the baseboard management controller 111 through the first network channel, so that the baseboard management controller 111 controls the server 100 based on the control instruction.
In the first network channel and the second network channel, a server manager can select a network channel to be used according to actual needs. For example, when the server manager needs to use the first network channel, other network devices may be connected to the server 100 through the first network interface 121.
In the server 100 shown in fig. 1, the baseboard management controller 111 needs to provide two ports, and each port needs one MAC address resource. Because the MAC address resources of the baseboard management controller 111 are limited, this circuit connection method occupies more MAC address resources and needs improvement.
Please refer to fig. 2 and 3. Fig. 2 is a schematic diagram of a portion of a server 200 according to another embodiment of the present application. Fig. 3 is a schematic diagram of a portion of a server 300 according to another embodiment of the present application.
Fig. 2 is substantially similar to fig. 1, with the main differences: in the server 200, the back window 22 includes a first network interface 221, and the front window does not include a network interface. The main board 21 includes a conversion card 213, a first resistor R1, and a second resistor R2. The second network switch chip 2131 and the first connector 2141 are integrated within the switch card 213. The baseboard management controller 211 includes a port 2111. The port 2111 is connected to the first network conversion chip 212 through a first resistor R1. The port 2111, the first resistor R1, the first network conversion chip 212, and the first network interface 221 form a network channel.
The server 300 in fig. 3 and the server 200 in fig. 2 comprise the same motherboard 21. The main difference between the server 300 and the server 200 is that in the server 300, the front window 33 includes the second connector 331 and the second network interface 332, and the rear window does not include a network interface. Port 2111 is connected to switch card 213 through a second resistor R2. The port 2111, the second resistor R2, the switch card 213, the second connector 331, and the second network interface 332 form a network channel.
As can be seen from fig. 2 and 3, the main board 21 is adapted to a server 200 where only the back window 22 includes a network interface or a server 300 where only the front window 33 includes a network interface. When the motherboard 21 needs to adapt to the server 200 with the rear window 22 including the network interface, the first resistor R1 is installed (i.e. the first resistor R1 is connected with the port 2111 and the first network conversion chip 212 through the wiring of the circuit board), so that the baseboard management controller 211 can send and receive messages through the first network interface 221; when the motherboard 21 needs to adapt to the server 300 with the front window 33 including the network interface, the second resistor R2 is installed (i.e. the second resistor R2 is connected to the port 2111 and the switch card 213 through the circuit board wiring), so that the baseboard management controller 211 can send and receive messages through the second network interface 332.
In the servers of fig. 2 and 3, although the MAC address occupation of the baseboard management controller 211 is reduced, correspondingly, the network interfaces cannot be set in the front window and the rear window of the server at the same time, and the scope of selecting the network interfaces by the user is reduced. Meanwhile, since the motherboard 21 is adapted to two different types of servers at the same time, different PCBA (Printed Circuit Board Assembly) numbers need to be maintained for the motherboard 21 for the different types of servers to distinguish the resistors that need to be on-demand. For example, for the server in fig. 2, a first PCBA number needs to be maintained for the motherboard 21 to represent that the first resistor R1 is to be on-board; for the server in fig. 3, a second PCBA number needs to be maintained for the motherboard 21 to represent the second resistor R2 being on-die, which presents a production maintenance challenge.
In view of this, the present application provides a communication circuit of a server, which can simultaneously set a network interface on a front window and a rear window of the server, reduce the occupation of MAC address resources of a baseboard management controller, and reduce the difficulty of production maintenance. Referring to fig. 4, a block diagram of a communication circuit 400 according to an embodiment of the present application is provided. The communication circuit 400 is applicable to a server. The server comprises a main board 41, a rear window 42 and a front window 43. Rear window 42 may include rear window interface 421 and front window 43 may include front window interface 431. The back window interface 421 and the front window interface 431 are network interfaces.
The communication circuit 400 may be disposed on the motherboard 41 and includes a baseboard management controller 411, a switch 413, and a switch controller 412. The switch 413 is configured to connect the baseboard management controller 411, and to connect the front window interface 431 in case the front window 43 includes the front window interface 431, and to connect the rear window interface 421 in case the rear window 42 includes the rear window interface 421. Specifically, in the embodiment shown in fig. 4, since the back window 42 includes the back window interface 421 and the front window 43 includes the front window interface 431, the switch 413 connects the baseboard management controller 411, the back window interface 421 and the front window interface 431 at the same time. The switch 413 may communicate the baseboard management controller 411 to one of the interfaces.
The switching controller 412 is configured to detect whether the front window 43 includes the front window interface 431 and detect whether the rear window 42 includes the rear window interface 421, and in the case where only the front window interface 431 or the rear window interface 421 is detected, control the switch 413 to communicate the substrate management controller 411 with the detected interface, and in the case where the front window interface 431 and the rear window interface 421 are detected at the same time, control the switch 413 to communicate the substrate management controller 411 with one of the interfaces. Specifically, when the switching controller 412 outputs the first control signal to the switch 413, the switch 413 controls the baseboard management controller 411 to communicate with the back window 421; when the switching controller 412 outputs the second control signal to the switch 413, the switch 413 controls the baseboard management controller 411 and the front window interface 431 to communicate. For example, the first control signal may be a high level and the second control signal may be a low level.
In some embodiments, for the case where the back window 42 includes the back window interface 421 and the front window 43 includes the front window interface 431, default interfaces and interface switching conditions may be preset in the control code of the switching controller 412. The default interface refers to an interface that is in default communication with the baseboard management controller 411. The interface switching condition may refer to a condition that an interface communicating with the baseboard management controller 411 is switched from one interface to another. The switch controller 412 may control the switch 413 to first communicate the baseboard management controller 411 with a default interface, and in case that the interface switching condition is satisfied, then control the switch 413 to communicate the baseboard management controller 411 with another interface other than the default interface, so as to implement the interface switching. In the present embodiment, the rear window interface 421 is set as a default interface. The switching controller 412 controls the switch 413 to first communicate the baseboard management controller 411 with the rear window interface 421, and when the interface switching condition is satisfied, controls the switch 413 to communicate the baseboard management controller 411 with the front window interface 431.
The interface switching condition can be set according to the actual situation. In this embodiment, the communication circuit 400 further includes a flip-flop 414 connected to the switching controller 412. When the switch controller 412 detects the front window interface 431 and the rear window interface 421 at the same time and controls the switch 413 to communicate with the baseboard management controller 411 and one of the interfaces, if a switch signal sent by the trigger 414 is received, the switch 413 is controlled to perform a switch operation to switch the interface communicated with the baseboard management controller 411. In short, the switching signal sent by the trigger 414 may be received as an interface switching condition. Trigger 414 may be a component that allows a server administrator to operate. In this way, the server manager can switch and control the interface communicated with the baseboard management controller 411 through operating the trigger 414 according to actual needs, so that the operation is more convenient.
Specifically, the trigger 414 may include a trigger switch 4141, where the trigger switch 4141 is located outside the housing of the server, and when the trigger switch 4141 is in the first switch state, the trigger 414 is configured to send a switching signal to the switching controller 412, and when the trigger switch 4141 is in the second switch state, the trigger 414 is configured to send a signal other than the switching signal to the switching controller 412. The first switch state and the second switch state may be different. The server manager can change the state of the trigger switch 4141 by manual operation. In this embodiment, the trigger switch 4141 is a key. When the trigger switch 4141 is in the first switch state being pressed, the trigger 414 sends a switching signal (such as a high level) to the switching controller 412; when the trigger switch 4141 is in the second switch state that is not pressed, the trigger 414 sends a signal other than the switching signal (such as a low level) to the switching controller 412. By changing the state of the trigger switch 4141 to control the interface with the baseboard management controller 411, the solution is easier to implement. Meanwhile, the trigger switch 4141 is arranged outside the server housing, so that the operation of a server manager is facilitated. It is understood that the trigger switch 4141 may comprise various forms, and any switch having two or more different switch states is within the scope of the present application. For example, the trigger switch 4141 may also be a slide switch. When the sliding switch is slid to the first position, the sliding switch is indicated to be in a first switch state; when the sliding switch slides to the second position, the sliding switch is in the second switch state.
In other embodiments, the handoff controller 412 may be communicatively coupled to the baseboard management controller 411. The server manager may issue a switching control instruction through the management interface of the baseboard management controller 411. The baseboard management controller 411 transmits a switching control message to the switching controller 412 based on the switching control instruction, and causes the switching controller 412 to control the switcher 413 to switch the interface communicating with the baseboard management controller 411. In these embodiments, the handover control message sent by the baseboard management controller 411 may be received by the handover controller 412 as an interface handover condition. In this way, the flip-flop 414 can be omitted, and the circuit size of the communication circuit 400 can be reduced.
The following describes how the switching controller 412 detects whether the front window 43 includes the front window interface 431 and whether the rear window 42 includes the rear window interface 421.
In some embodiments, the switching controller 412 includes a first detection end P1 and a second detection end P2, where the first detection end P1 is used to connect the front window interface 431 in case the front window 43 includes the front window interface 431, and where the rear window 42 includes the rear window interface 421, the second detection end P2 is used to connect the rear window interface 421. The switching controller 412 determines whether the front window 43 includes the front window interface 431 and the rear window 42 includes the rear window interface 421 by detecting whether the first and second detection terminals P1 and P2 are connected to the interfaces. Taking the first detection end P1 as an example. It will be appreciated that the first detection terminal P1 will only be connected to the interface if the front window 43 comprises a front window interface 431. If the first detection end P1 is not connected to the interface, it may indicate that the front window 43 does not include the front window interface 431. By detecting whether the first detecting end P1 and the second detecting end P2 are connected with the interfaces, whether the front window 43 includes the front window interface 431 and whether the rear window 42 includes the rear window interface 421 is indirectly determined, so that the scheme is easier to implement.
Further, considering that the first and second sensing terminals P1 and P2 have the first voltage signal (e.g., low level) in the case of being connected to the interface and the first and second sensing terminals P1 and P2 have the second voltage signal (e.g., high level) in the case of not being connected to the interface, the switching controller 412 may detect whether the first and second sensing terminals P1 and P2 are connected to the interface by detecting the voltage signals of the first and second sensing terminals P1 and P2. Whether the first detection end P1 and the second detection end P2 are connected with the interface is determined based on the voltages of the first detection end P1 and the second detection end P2, and an additional detection circuit is not required to be arranged, so that the cost of the communication circuit 400 can be reduced.
In summary, in the technical solutions of some embodiments of the present application, the switching controller 412 and the switching device 413 are introduced in the communication circuit 400. The switching controller 412 is configured to detect whether the front window 43 includes a front window interface 431 and whether the rear window 42 includes a rear window interface 421, and control the switching controller 413 to communicate the baseboard management controller 411 with one of the interfaces according to the detection result. As such, the front window interface 431 and the back window interface 421 may be connected to the same port of the baseboard management controller 411 through the switch 413. The switching controller 412 may cause the baseboard management controller 411 to communicate with the front window 421 or the rear window 431 by controlling the switching controller 413. That is, in the case that the server includes both the front window interface 431 and the back window interface 431, only one MAC address resource of the baseboard management controller 411 is occupied, so that the MAC address resource occupation of the baseboard management controller 411 can be reduced. In addition, a plurality of PCBA numbers do not need to be arranged for the main board 41, so that maintenance and management are convenient.

Through setting up the network conversion chip, can realize signal conversion, the application scope of circuit is wider.
Further, the communication circuit 500 and the front window 53 further include a connector 515.
