Detailed Description

In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

For a scenario requiring multiple network functions, the embodiment of the invention introduces a network switching (Switch) chip end to support the realization of at least two network port functions, such as a dual-network port chip, and the BMC communicates with the network switching chip end through a target chip end to realize the function of managing at least two network ports by the BMC.

As an example, the target chip may be an RTL (re-i semiconductor) chip, and of course, other chips may be used, which is not limited by the specific model of the chip in the present invention.

The MAC (MEDIA ACCESS Control Address) of the management chip end of the BMC in the server links with the target chip end through SGMII (Serial Gigabit media independent interface) mode, and the target chip end links with the network exchange chip end through RGMII (Reduced Gigabit media independent interface) mode, so that the function of BMC management of at least two network ports is realized.

The MII is a media independent interface, and is also called a media independent interface. It is an ethernet industry standard defined by ieee-802.3. It includes a data interface, and a management interface. The data interface comprises two separate channels for the transmitter and the receiver, respectively. Each channel has its own data, clock and control signals. The MII data interface requires a total of 16 signals. The management interface is a dual signal interface, one being a clock signal and the other being a data signal. Through the management interface, the upper layers can monitor and control the devices.

The GMII, gigabit media independent interface, is an 8-bit parallel synchronous transceiver interface, and adopts 8-bit interface data and a 125MHz working clock, and the transmission rate can reach 1000Mbps. And is compatible with the 10/100Mbps mode of operation specified by MII. The data structure of GMII conforms to the IEEE ethernet standard.

SGMII is a serial gigabit media independent interface, which refers to a serial interface between a device and a high-integration network chip. The SGMII interface specification 1.8 specifies the transmission rate, signaling format, timing requirements, impedance matching, etc. of the SGMII interface, and this specification requires that the SGMII interface must conform to standard signaling formats, including clock, data, control, etc. signal composition modes, to ensure normal communication between the device and the network chip, and specifies the timing requirements of the SGMII interface, including delay of data transmission, accuracy of clock signals, etc. These timing requirements are important to ensure reliability and stability of data transmission, and the impedance matching is specified to ensure the quality of the signal and stability of the transmission distance.

RGMII is a simple gigabit media independent interface, and adopts a 4-bit data interface, an operating clock is 125MHz, and data are transmitted simultaneously on the rising edge and the falling edge, so that the transmission rate can reach 1000Mbps. Meanwhile, the system is compatible with a 10/100Mbps working mode specified by MII, and supports the transmission rate: 10M/100M/1000Mb/s, which correspond to clk signals of: 2.5MHz/25MHz/125MHz. The RGMII data structure conforms to the IEEE Ethernet standard, and the purpose of the RGMII is to reduce the circuit cost, so that the pin number of a device for realizing the interface is reduced from 25 pins to 14 pins.

However, in the actual debugging process of the architecture, the problem that the network address cannot be set is found, which leads to the functional failure of the BMC remote management server, and also leads to the failure of normal interaction of the BMC with the data interacted with the BIOS (Basic Input Output System ) through the IPMI (INTELLIGENT PLATFORM MANAGEMENT INTERFACE, intelligent platform management interface) protocol, which leads to the complete failure of the functions.

Through analyzing the physical design scheme of the target chip, the network exchange chip and the BMC, the reason is that: when the target chip end works in the in-band RGMII mode, the downlink network exchange chip end is required to support the in-band self-adaptation function of the in-band RGMII mode, but the network exchange chip end does not support the in-band self-adaptation function, so that the target chip end and the network exchange chip end cannot normally communicate.

However, the target chip end supports the out-of-band adaptive function, and the network switching chip also supports the out-of-band adaptive function, and whether the network switching chip end can support the out-of-band adaptive function depends on: the MDIO (MANAGEMENT DATA Input/Output ) protocol of the target chip end.

The link mode of the MDIO protocol of the target chip end comprises the link of the MDIO protocol of the target chip end and the network exchange chip end, and the link of the MDIO protocol of the target chip end and the BMC.

On the one hand, if the MDIO protocol link of the target chip end is linked with the network exchange chip end, the out-of-band self-adaptation function of the network exchange chip end is supported; on the other hand, if the MDIO protocol link of the target chip end is linked with the BMC, the out-of-band self-adaptation function of the network switching chip end cannot be supported.

Based on the method, according to different conditions of the physical link modes of the MDIO protocol of the target chip end, different network communication modes among the BMC end, the target chip and the network switching chip can be automatically set, and effective setting of at least two network ports in the network switching chip is realized in the different network communication modes.

For linking the MDIO protocol link with the network exchange chip end, the out-of-band self-adaptation function of the network exchange chip end is supported, so that the BMC can communicate with the network exchange chip end in SGMII mode-RGMII mode through the target chip end by adopting the out-of-band self-adaptation function of the network exchange chip end.

For the condition that the MDIO protocol link of the target chip end is linked with the BMC, the BMC cannot carry out SGMII mode-RGMII mode communication with the network exchange chip end through the target chip end because the out-of-band self-adaption function of the network exchange chip end cannot be supported, the target chip end supports 1000base-X (optical fiber gigabit Ethernet) protocol, the network exchange chip end also supports 1000-BaseX protocol, and then normal communication between the target chip end and the network exchange chip end can be realized through 1000-BaseX protocol.

It can be understood that, according to different physical link setting manners of the MDIO protocol of the target chip end, the supported network communication protocols of the BMC, the target chip end, and the network exchange chip end are also different, which is specifically as follows:

When the MDIO protocol of the target chip end is linked with the network exchange chip end in a physical linking mode, the BMC is physically linked with the target chip end through an SGMII mode, the target chip end is linked with the network exchange chip end through an RGMII mode, the network exchange chip supports an out-of-band self-adaptive mode, and the BMC communicates with the network exchange chip end through the target chip end in the SGMII mode-RGMII mode.

When the physical link mode of the MDIO protocol of the target chip end is that the target chip end and the BMC are physically linked, the communication mode of the configuration network is adjusted to be that the FIBER (optical FIBER) is communicated with the 1000Base-X protocol in the RGMII mode. When the server is started, the BMC reads whether the current mode of the target chip is 1000base-X protocol through the MDIO protocol, if the current mode is not 1000base-X protocol, the current mode is set to be 1000base-X protocol, and the working mode of the network exchange chip end, the port enabling setting of the network exchange chip end, the port reading and writing setting of the network exchange chip end and the port time delay setting of the network exchange chip end are set through the MDIO protocol, so that the normal network communication function of the 1000base-X protocol is realized.

The invention is further described below with reference to the accompanying drawings:

Referring to fig. 1, a flowchart illustrating steps of a server-based communication method according to some embodiments of the present invention is shown, where a baseboard management controller communicates with a network switch chip end through a target chip end, where the network switch chip end provides at least two network ports, such as a dual-port chip, and in some examples, the at least two network ports provided by the network switch chip end include: the baseboard management controller can provide external services, such as the function of a remote management server, through at least two network ports.

Specifically, the method comprises the following steps:

Step 101, detecting a link mode of managing a data input/output protocol in the target chip end.

In practical application, the link mode of the MDIO protocol in the target chip end can be detected.

Step 102, controlling the baseboard management controller to communicate with the target chip end by using an optical fiber gigabit ethernet protocol in an optical fiber mode when the link mode is that the target chip end is linked with the baseboard management controller, and communicating with the network switching chip end by using an optical fiber gigabit ethernet protocol in a reduced gigabit media independent interface mode.

Wherein, the gigabit ethernet protocol is 1000BASE-X protocol, 1000 means that the transmission rate is 1000m, BASE is baseband transmission, and X represents a single-mode or multimode fiber. In terms of protocols, 1000BASE-X has two hot-swappable packages, namely SFP (Small Form Pluggable, a small pluggable optical module package), GBIC (Gigabit Interface Converter, an optical module package with standardized package interface), and pin packages such as 1*9. From the packaging perspective, the SFP is an interface of the device, and the 1000BASE-X protocol product can be made into an SFP package.

For the condition that the MDIO protocol link of the target chip end is linked with the BMC, the BMC cannot carry out SGMII mode-RGMII mode communication with the network exchange chip end through the target chip end because the out-of-band self-adaption function of the network exchange chip end cannot be supported, the target chip end supports 1000base-X protocol, the network exchange chip end also supports 1000-BaseX protocol, and then normal communication between the target chip end and the network exchange chip end can be realized through 1000-BaseX protocol.

Specifically, 1000Base-X protocol in FIBER mode may be used for communication between the BMC and the target chip, and 1000Base-X protocol in RGMII mode may be used for communication between the target chip and the network switch chip.

That is, the communication means may include:

1. BMC-1000 Base-X protocol under FIBER mode-target chip end-1000 Base-X protocol under RGMII mode-network exchange chip end;

2. network exchange chip end-1000 Base-X protocol in RGMII mode-target chip end-1000 Base-X protocol in FIBER mode-BMC.

In some embodiments of the present invention, when the linking manner is that the target chip end is linked to the baseboard management controller, the baseboard management controller and the target chip end are controlled to communicate by using an optical fiber gigabit ethernet protocol in an optical fiber mode, and the target chip end and the network switch chip end communicate by using an optical fiber gigabit ethernet protocol in a reduced gigabit media independent interface mode, including:

And step 11, receiving a terminal request aiming at the server through the network port provided by the network exchange chip end.

And step 12, controlling the network exchange chip end to adopt the optical fiber gigabit Ethernet protocol in the independent interface mode of the simple gigabit media to send the terminal request to the target chip end and controlling the target chip end to adopt the optical fiber gigabit Ethernet protocol in the optical fiber mode to send the terminal request to the baseboard management controller under the condition that the link mode is that the target chip end is linked with the baseboard management controller.

And 13, controlling the baseboard management controller to adopt an optical fiber gigabit Ethernet protocol in an optical fiber mode, sending a reply message aiming at the terminal request feedback to the target chip end, controlling the target chip end to adopt the optical fiber gigabit Ethernet protocol in a simple gigabit media independent interface mode, sending the reply message to the network exchange chip end, and feeding the reply message back to the terminal through a network port provided by the network exchange chip end.

In practical application, the terminal may send a terminal request to the server, where the terminal request may include a remote management request, that is, the terminal is a remote terminal, and the request is sent by a remote connection manner, a destination address of the terminal request may be an address of a network port provided by the network exchange chip end, and the server may receive the terminal request through the network port provided by the network exchange chip end.

Because the link mode is that the target chip end is linked with the baseboard management controller, after receiving the terminal request, the network exchange chip end can adopt the optical fiber gigabit Ethernet protocol in the independent interface mode of the simple gigabit media to send the terminal request to the target chip end, and the target chip end can adopt the optical fiber gigabit Ethernet protocol in the optical fiber mode to send the terminal request to the baseboard management controller.

After processing the terminal request, a reply message can be generated, and because the link mode is that the target chip end is linked with the baseboard management controller, the baseboard management controller can adopt an optical fiber gigabit Ethernet protocol in an optical fiber mode to send the reply message fed back for the terminal request to the target chip end, the target chip end can adopt the optical fiber gigabit Ethernet protocol in a simple gigabit media independent interface mode to send the reply message to the network exchange chip end, and the network exchange chip end can feed back the reply message to the terminal through a provided network port, so that the whole communication interaction process is realized, and the terminal request is responded.

In some embodiments of the invention, further comprising:

Specifically, between the BMC and the target chip end, an SGMII mode may be used for communication, and between the target chip end and the network switch chip end, an RGMII mode may be used for communication.

That is, the communication means may include:

1. BMC-SGMII mode-target chip end-RGMII mode-network exchange chip end;

2. network switching chip side-SGMII mode-target chip side-RGMII mode-BMC.

In the embodiment of the invention, different network communication modes among the BMC end, the target chip and the network exchange chip are automatically set according to different conditions of the physical link mode of the MDIO protocol of the target chip end, and the effective setting of at least two network ports in the network exchange chip is realized under different network communication modes, so that the compatibility is improved, and the normal interaction of network communication is ensured.

In some embodiments of the present invention, before the controlling the communication between the baseboard management controller and the target chip end using the optical fiber gigabit ethernet protocol in the optical fiber mode, and the communicating between the target chip end and the network switching chip end using the optical fiber gigabit ethernet protocol in the reduced gigabit media independent interface mode, the method further includes:

Specifically, the MDIO protocol link of the target chip end can be set to be linked with the network exchange chip end, or the MDIO protocol link of the target chip end is linked with the BMC.

In some embodiments of the present invention, the setting a link manner of managing a data input/output protocol in the target chip according to an input operation includes:

Acquiring a selection result of options in a basic input/output system, and setting a link mode of a management data input/output protocol in the target chip end according to the selection result; or receiving a control instruction to the baseboard management controller, and setting a link mode of a management data input/output protocol in the target chip end according to the control instruction; or receiving an operation instruction of the jump cap operation of the main board end, and setting a link mode of the management data input/output protocol in the target chip end according to the operation instruction.

In practical applications, various ways may be provided to perform the input operation, so as to set a link way of the MDIO protocol in the target chip end, and as some examples, the input operation includes any one of the following: input operation is performed by an option mode in a Basic Input Output System (BIOS), input operation is performed by a mode controlled by a Baseboard Management Controller (BMC), and input operation is performed by a mode that a main board end jumps to a cap.

In some examples, the setting of the link mode of the MDIO protocol may be implemented through an automation script, for example, the automation script may automatically select an option in the BIOS to implement the setting of the link mode, and by executing the automation script, the operation may be simplified, the efficiency may be improved, and the operation threshold may be reduced.

When the physical link mode of the MDIO protocol of the target chip end is that the target chip end and the BMC are physically linked, the network communication mode is adjusted to be the communication between the FIBER and the 1000Base-X protocol in the RGMII mode. Specifically, the BMC is set to link with an uplink port of the target chip end by adopting a 1000Base-X protocol in the FIBER mode, and the downlink port of the target chip end is set to link with the network exchange chip end by adopting a 1000Base-X protocol in the RGMII mode.

In the embodiment of the invention, the communication modes of the BMC, the target chip end and the network exchange chip end are set on the server side according to the physical link mode of the MDIO protocol of the target chip end, so that normal communication can be ensured under the link mode of the MDIO protocol, at least two network ports provided by the BMC management network exchange chip end are further realized, and the network management system is suitable for scenes requiring the use of a plurality of network functions.

In practical application, the 25M clock frequency can be introduced into the network exchange chip end by the server main board, so that the required clock frequency can be provided for the network exchange chip end, the operation of the network exchange chip end is ensured by providing the required clock frequency for the network exchange chip end, and the clock frequency of the server main board is directly adopted as the required clock frequency of the network exchange chip end, so that the operation is simplified.

In practical application, the BMC can read whether the current mode of the target chip is 1000base-X protocol through the MDIO protocol, and if the current mode is not 1000base-X protocol, the current mode can be set to 1000base-X protocol through the MDIO protocol.

In some embodiments of the present invention, in the process of starting the server, setting the working mode of the target chip end, so that the working mode of the target chip end supports communication by adopting an optical fiber gigabit ethernet protocol in an optical fiber mode and an optical fiber gigabit ethernet protocol in a reduced gigabit media independent interface mode, including:

In practical application, the BMC may read the parameters in the register of the target chip, and if the parameters in the register are non-specified parameters, for example, the specified parameters are 0X01, and the current mode is not 1000base-X protocol, the parameters in the register may be modified to the specified parameters to be set to 1000base-X protocol.

In some embodiments of the present invention, after setting, by the baseboard management controller, parameters in a register of the target chip end in the process of starting the server, so that the working mode of the target chip end supports communication by adopting the optical fiber gigabit ethernet protocol in the optical fiber mode and the optical fiber gigabit ethernet protocol in the abbreviated gigabit media independent interface mode, the method further includes:

In some embodiments of the invention, further comprising:

After setting the parameters in the register, the parameters in the register can be read back, and whether the working mode of the target chip end is set correctly is judged through the read-back parameters.

Referring to fig. 2, a flowchart illustrating steps of another communication method based on a server according to some embodiments of the present invention is shown, where a baseboard management controller in the server communicates with a network switching chip end through a target chip end, where the network switching chip end provides at least two network ports, and the baseboard management controller provides external services through the at least two network ports.

Specifically, the method comprises the following steps:

Step 201, according to the input operation, setting a linking mode of managing the data input/output protocol in the target chip end.

Step 202, detecting a link mode of managing a data input/output protocol in the target chip end.

Step 203, in the case that the linking manner is that the target chip end is linked with the baseboard management controller, the baseboard management controller is set to link with the uplink port of the target chip end by adopting the optical fiber gigabit ethernet protocol in the optical fiber mode, and the downlink port of the target chip end is set to link with the network switching chip end by adopting the optical fiber gigabit ethernet protocol in the reduced gigabit media independent interface mode.

The invention is illustrated below in connection with fig. 3a and 3 b:

referring to fig. 3a, the target chip is an RTL chip, and the network Switch chip is a network Switch chip, input operation may be performed through options in the BIOS, BMC control, a motherboard end skip cap, etc., so as to set a link mode of an MDIO protocol at the RTL chip end. When the physical link mode of the MDIO protocol of the RTL chip end is that the RTL chip end and the BMC are physically linked, 1000Base-X protocol under the FIBER mode can be adopted for communication between the BMC and the target chip end, and 1000Base-X protocol under the RGMII mode can be adopted for communication between the target chip end and the network Switch chip end.

As shown in fig. 3b, on the server side, input operations may be performed through options in the BIOS, BMC control, a jump cap at the motherboard end, and so on, so as to set a link manner of the MDIO protocol at the RTL chip end.

The MDIO protocol is linked in a physical way that the RTL chip end and the network Switch chip end are linked physically, and the out-of-band self-adapting function of the network Switch chip end is supported, so that the out-of-band self-adapting function of the network Switch chip end can be adopted, the BMC is communicated with the RTL chip end through the SGMII mode in a connection mode, and the RTL chip end is communicated with the network Switch chip end through the RGMII mode in a connection mode.

When the MDIO protocol is linked physically between the RTL chip end and the BMC, the network Switch chip does not support the RGMII out-of-band self-adaption function, but only supports the FIBER mode-1000 Base-x mode, the BMC sets the FIBER 1000Base-x mode to be linked with the upstream port of the RTL chip end, and the downstream port of the RTL chip end sets the RGMII 1000BASE-x mode to be linked with the network Switch chip.

Further, the server motherboard may provide a 25Mhz clock frequency to the network Switch chip.

When the server is started, the BMC configures the RTL chip end through the MDIO protocol, the working mode of the RTL chip end is set to FBER-RGMIl mode, namely the register is set to 1, and whether the working mode of the RTL chip end is correct or not can be read through the MDIO protocol.

If the read RTL chip end working mode is incorrect, the BMC is characterized in that the network communication of the firmware is failed, and if the read RTL chip end working mode is correct, the BMC sets the network Switch chip working mode, the port enabling setting, the network port reading and writing setting and the port time delay setting through an MDIO protocol.

After the setting is completed, the communication function of the BMC for managing the network address of the main board is normally used based on the working mode of the 1000Base-x protocol.
