Step 301, BMC obtains UART serial data, and this UART serial data includes that serially printing is believed Breath.Wherein, this UART serial data is the UART serial data of mainboard, and/or, the UART of BMC Serial data.Such as, this UART serial data can be the UART serial data of at least two mainboard, Or, can be the UART serial data of BMC, or, can be the UART of at least one mainboard The UART serial data of serial data and BMC.

BMC obtains the process of UART serial data of mainboard, can include but not limited to following situation:

Situation one, as shown in Figure 4, disposes FPGA (Field Programmable between BMC and mainboard Gate Array, field programmable gate array), i.e. mainboard is carried out data transmission by FPGA with BMC. And, mainboard is carried out data transmission with BMC by a UART bus.In the diagram, each mainboard To there being a lpc bus, the most each mainboard carries out data biography by the lpc bus of self with FPGA Defeated, but, FPGA is only carried out data transmission with BMC by a UART bus, so, and Mei Gezhu Plate can be carried out data transmission with BMC by this unique UART bus.

LPC serial data is exported to FPGA by the first mainboard by lpc bus.FPGA receives from the The LPC serial data of one mainboard, is converted into UART serial data by LPC serial data, and passes through UART bus between BMC and FPGA, is sent to the UART serial data of the first mainboard BMC.BMC receives the UART serial data of the first mainboard that FPGA is sent by UART bus.

Situation two, as shown in Figure 4, disposes FPGA, i.e. mainboard between BMC and mainboard and leads to BMC Cross FPGA to carry out data transmission.And mainboard is carried out data transmission with BMC by a UART bus. In the diagram, each mainboard is to there being a UART bus, and the most each mainboard is total by the UART of self Line carries out data transmission with FPGA, but, FPGA is only by a UART bus and BMC number According to transmission, so, each mainboard can be carried out data transmission with BMC by this unique UART bus.

UART serial data is exported to FPGA by the first mainboard by UART bus.FPGA receives From the UART serial data of the first mainboard, no longer carry out the conversion operation of serial data, directly pass through BMC And the UART bus between FPGA, is sent to BMC by the UART serial data of the first mainboard.BMC Receive the UART serial data of the first mainboard that FPGA is sent by UART bus.

Situation three is as it is shown in figure 5, dispose FPGA, i.e. mainboard and lead to BMC between BMC and mainboard Cross FPGA to carry out data transmission.And, mainboard carries out data biography by multiple UART buses with BMC Defeated.In Figure 5, each mainboard is to there being a lpc bus, and the most each mainboard is total by the LPC of self Line carries out data transmission with FPGA, and, FPGA carries out data by multiple UART buses with BMC Transmission, so, each mainboard can a corresponding UART bus, and can be by UART corresponding to this mainboard Bus carries out data transmission with BMC.

Wherein, when the quantity of mainboard, time identical with the UART bus number between FPGA and BMC, The most each mainboard can a corresponding unique UART bus, such as, between BMC and FPGA The corresponding mainboard 1 of UART bus 1, the corresponding mainboard 2 of UART bus 2, the corresponding mainboard 3 of UART bus 3. Or, can there is the corresponding same UART bus of part mainboard, and have UART bus free, such as, The corresponding mainboard of UART bus 11 between BMC with FPGA and mainboard 2, UART bus 2 is corresponding main Plate 3, UART bus 3 is idle.When the quantity of mainboard, and the UART bus between FPGA and BMC During quantity difference, the most each mainboard can a corresponding unique UART bus, for example, it is assumed that UART Bus number more than the quantity of mainboard, then the corresponding mainboard of UART bus 11 between BMC with FPGA, The corresponding mainboard 2 of UART bus 2, the corresponding mainboard 3 of UART bus 3, but UART bus 4 is idle. Or, can have the corresponding same UART bus of part mainboard, for example, it is assumed that UART bus number is little In the quantity of mainboard, then the corresponding mainboard of UART bus 11 between BMC with FPGA and mainboard 2, The corresponding mainboard 3 of UART bus 2.

It is, of course, also possible to there is the corresponded manner of other mainboard and UART bus, the present embodiment repeats no more.

LPC serial data is exported to FPGA by the second mainboard by lpc bus.FPGA receives from the The LPC serial data of two mainboards, is converted into UART serial data by LPC serial data, and by second The UART serial data of the second mainboard is sent to BMC by the UART bus that mainboard is corresponding.BMC receives The UART serial data of the second mainboard that FPGA is sent by the UART bus that the second mainboard is corresponding.

Situation four is as it is shown in figure 5, dispose FPGA, i.e. mainboard and lead to BMC between BMC and mainboard Cross FPGA to carry out data transmission.And, mainboard carries out data biography by multiple UART buses with BMC Defeated.In Figure 5, each mainboard to there being a UART bus, the most each mainboard UART by self Bus carries out data transmission with FPGA, and, FPGA is by multiple UART buses and BMC number According to transmission, so, each mainboard can a corresponding UART bus, and can be corresponding by this mainboard UART bus carries out data transmission with BMC.Wherein, for the corresponded manner of mainboard Yu UART bus, It is referred to situation three, does not repeats them here, corresponding with the UART bus 1 between BMC with FPGA Mainboard 1, the corresponding mainboard 2 of UART bus 2, as a example by the corresponding mainboard 3 of UART bus 3.

UART serial data is exported to FPGA by the second mainboard by UART bus.FPGA receives From the UART serial data of the second mainboard, do not carry out the conversion operation of serial data, by the second mainboard pair The UART serial data of the second mainboard is sent to BMC by the UART bus answered.BMC receives FPGA By the UART serial data of the second mainboard that the UART bus that the second mainboard is corresponding sends.

Situation five, as shown in Figure 6, does not disposes FPGA, i.e. mainboard and BMC between BMC and mainboard Directly carried out data transmission by UART bus, and, mainboard is by multiple UART buses and BMC Carry out data transmission.In figure 6, the corresponding mainboard of each UART bus.Such as, UART bus 1 corresponding mainboard 1, the corresponding mainboard 2 of UART bus 2, the corresponding mainboard 3 of UART bus 3.

UART serial data is exported to BMC by the 3rd mainboard by UART bus.BMC receives the 3rd The UART serial data that mainboard is sent by the UART bus that the 3rd mainboard is corresponding.

Situation six, as shown in Figure 6, does not disposes FPGA, i.e. mainboard and BMC between BMC and mainboard Directly carried out data transmission by lpc bus, and, mainboard is carried out with BMC by multiple lpc bus Data are transmitted.In figure 6, the corresponding mainboard of each lpc bus.Such as, lpc bus 1 is corresponding main Plate 1, the corresponding mainboard 2 of lpc bus 2, the corresponding mainboard 3 of lpc bus 3.

LPC serial data is exported to BMC by the 3rd mainboard by lpc bus.BMC receives the 3rd mainboard The LPC serial data sent by the lpc bus that the 3rd mainboard is corresponding, and LPC serial data is changed Become UART serial data, thus obtain the UART serial data that the 3rd mainboard is corresponding.

For above-mentioned situation one to situation six, in actual applications, can select flexibly BMC and mainboard it Between networking mode, selecting after certain networking mode, then using the processing mode of correspondence to process.Example As, when BMC supports to be converted into LPC serial data UART serial data, and can BMC with When disposing a lpc bus between each mainboard, then can use the networking mode of situation six, and use feelings Condition six processes.The most such as, do not support to be converted into LPC serial data UART serial ports number as BMC According to, and when mainboard uses lpc bus, then can use situation one or the networking mode of situation three, lead Dispose FPGA between plate and BMC, and use situation one or situation three to process.

For above-mentioned situation one to situation six, the first mainboard, the second mainboard, the 3rd mainboard are intended merely to distinguish Different situations, a kind of example be given.First mainboard, the second mainboard, the 3rd mainboard can be identical, also Can be different.First mainboard, the second mainboard, the 3rd mainboard may each be a mainboard, it is also possible to be multiple Mainboard.Such as, the first mainboard is mainboard 1, mainboard 2 and mainboard 3, and the second mainboard is mainboard 1, mainboard 2 With mainboard 3, the 3rd mainboard is mainboard 1, mainboard 2 and mainboard 3.Which kind of so, no matter use at situation Reason, BMC all can get the UART serial data of mainboard 1, mainboard 2 and mainboard 3.

For above-mentioned situation one and situation two, between FPGA and BMC, owing to multiple mainboards share one UART bus, therefore, FPGA is once merely able to be sent to the UART serial data of a mainboard BMC.On this basis, BMC can pass through local bus (Local Bus) to FPGA transmission the first master The request message of the UART serial data of plate, so that FPGA obtains and sends the UART string of the first mainboard Mouth data, so, BMC just can receive the UART serial data of the first mainboard.

Such as, BMC first sends the request message of the UART serial data of mainboard 1 to FPGA, and receives The UART serial data of mainboard 1.Afterwards, BMC sends the UART serial ports number of mainboard 2 to FPGA According to request message, and receive the UART serial data of mainboard 2.By that analogy.

Said process is the process that BMC obtains the UART serial data of mainboard, obtains this for BMC The process of the UART serial data of BMC, as it is shown in fig. 7, go here and there by the UART exported by BMC Mouth, then input back another UART serial ports of BMC, so, BMC is exported by this UART serial ports UART serial data, be input back to another UART serial ports of BMC, so that BMC can Get the UART serial data of this BMC.

The UART serial ports that BMC exports is inputted back again the mode of another UART serial ports of BMC, can To include but not limited to: the RX of the TX (transmitting terminal) of UART serial ports with another UART serial ports (is connect Receiving end) docking, the RX of UART serial ports is docked with the TX of another UART serial ports.

In step 301, BMC can get the UART serial data of mainboard and/or this BMC UART serial data, in subsequent process, not repartitioning is the UART serial data of mainboard, or The UART serial data of BMC, is collectively referred to as UART serial data.

Step 302, the UART serial data obtained is packaged by BMC, the UART serial ports after encapsulation Data include the identification information belonging to serial printing information, serial printing information.Wherein, the UART after encapsulation Serial data includes the identification information of the mainboard belonging to serial printing information or BMC.

Wherein, when the UART serial data obtained is packaged, the UART serial ports that can will obtain Data are packaged into UDP message, and this UDP message includes the serial printing information (serially printing such as mainboard Information) and this serial printing information belonging to mainboard or the identification information of BMC.

Step 303, the UART serial data data after encapsulation are sent to remote console by BMC, as logical Cross LAN and the UART serial data (such as UDP message) after encapsulation is sent to remote console.

Wherein, above-mentioned LPC serial data, UART serial data, UDP message all carry serial ports Type information, the data form simply carrying serial printing information is different.

For the UART serial data after the encapsulation that remote console sends, in the embodiment of the present invention, by The serial ports of the serial printing information and/or BMC that can carry mainboard in the UART serial data after encapsulation is beaten Official seal ceases, accordingly, it would be desirable to make a distinction serial printing information, i.e. in the UART serial data after encapsulation Carry the identification information of the mainboard belonging to serial printing information or BMC.Such as, serially printing letter is carried Breath 1 and the corresponding relation of mainboard 1, serial printing information 2 and the corresponding relation of mainboard 2, serially printing is believed The corresponding relation etc. of breath 3 and BMC.

In order to get the identification information of the mainboard belonging to serial printing information, for situation one and situation two, Owing to FPGA sends the UART serial data of each mainboard by same UART bus to BMC, Therefore, BMC cannot distinguish the UART serial data of each mainboard based on UART bus.Based on this, Owing to FPGA knows that oneself currently obtain is the UART serial data of which mainboard, therefore, FPGA When sending UART serial data to BMC, serially printing can be added in this UART serial data The identification information of the mainboard belonging to information, so, BMC is after receiving UART serial data, it is possible to from UART serial data gets the identification information of mainboard belonging to serial printing information.

For situation three to situation six, sent each master by then passing through different UART buses to BMC The UART serial data of plate, and the corresponding unique mainboard of each UART bus, therefore, BMC can be with base The UART serial data of each mainboard is distinguished in UART bus.Based on this, BMC is by certain After UART bus receives UART serial data, it is possible to get the mainboard belonging to serial printing information For the mainboard that this UART bus is corresponding, then get the identification information of this mainboard.

Certainly, UART serial ports number is being sent for situation three to situation six, FPGA or mainboard to BMC According to time, it is also possible to added belonging to serial printing information in this UART serial data by FPGA or mainboard The identification information of mainboard, so, BMC is after receiving UART serial data, it is possible to from UART Serial data gets the identification information of mainboard belonging to serial printing information.

Wherein, BMC can pass through IPMI (Intelligent Platform Management Interface Specification, IPMI specification) agreement, the UART serial data encapsulation that will get Become UDP message.And based on current IPMI protocol, the UART serial data that BMC only can will get The Information encapsulation such as (this UART serial data carries serial printing information), user name password is to UDP number According to, without the mainboard belonging to encapsulation serial printing information or the identification information of BMC.

Based on this, in the embodiment of the present invention, current IPMI protocol can be modified, with based on repairing After changing IPMI protocol encapsulation UART serial data time, can by the UART serial data got, Mainboard or the Information encapsulation such as the identification information of BMC, user name password belonging to serial printing information arrive UDP message.Or, it is also possible to use self-defining agreement, based on self-defining protocol encapsulation UART During serial data, can by the mainboard belonging to the UART serial data got, serial printing information or The Information encapsulations such as the identification information of BMC, user name password are to UDP message.

In the above embodiment of the present invention, BMC, FPGA, multiple mainboard all may be located at server (as micro- Server or ARM server etc.) in, as being based in the server of Intel X86-based.

Based on technique scheme, in the embodiment of the present invention, BMC can manage multiple mainboard, and gets The serial printing information of multiple mainboards, and be sent to remotely control by the serial printing information of these multiple mainboards Platform, so that attendant can check the serial printing information of multiple mainboard on remote console, just simultaneously Analyze and orientation problem in attendant.Such as, start asking of just there will be for certain multiple mainboard simultaneously Topic, serial printing information based on a mainboard, attendant cannot analyze and orientation problem, but, as Really attendant can view the serial printing information of multiple mainboard simultaneously, it is possible to analyze and location is asked Topic, such that it is able to provide help for solving this problem.And, the serial ports of this BMC can also be beaten by BMC Official seal breath is sent to remote console, so that attendant can check this BMC's on remote console Serial printing information, it is simple to the problem that attendant analyzes and positions this BMC.

In the embodiment of the present invention, BMC is getting UART serial data (the UART serial ports number such as mainboard According to and/or the UART serial data of BMC) after, it is also possible to from UART serial data, parse string Mouth type information, and serial printing information is performed one or more of following operation:
