Monitor of rear card board in a kind of intelligent-platform management interface system

Technical field

The present invention relates to communication technique field, relate in particular to the monitor of rear card board in a kind of intelligent-platform management interface system.

Background technology

IPMI (Intelligent Platform Management Interface, IPMI) comes from the server field, be the intelligent platform management interface standard that each network development merchant releases for the availability index that improves server, purpose is that functions such as equipment control, transducer/incident management, user management, fan frame/power shelf management, remote maintenance are provided for server; It is independent of primary processor and hardware platform is monitored and controls.And IPMI provides (InBand) maintenance channel in band outer (SideBand) and the band, and out-band channel and in-band channel are separate.

The expansion of IPMI supporting platform management, by IPMB (Intelligent Platform ManagementBus, Intelligent Platform Management Bus), realize BMC (Baseboard ManagementController, baseboard management controller) and the communication of SMC (Satellite Management Controller, Satellite Management Controller).IPMB is a kind of bus interface of IPMI, its position in IPMI as shown in Figure 1, the IPMB bus has connected SMM (System Management Module, system management module) the BMC module of the CMM on the plate (Chassis Management Module, Shelf management module) module and other veneers.The BMC module of each veneer is the core of IPMI, between system bus and platform management hardware, provide and the interface of system bus and the interface of platform management hardware, be used for the veneer at own place is managed, equipment control, transducer/incident management, fan frame/power shelf information of managing are reported the SMM plate.Simultaneously, the SMM plate also can carry out communication with user interface, and wherein the UI control desk is a user control interface, realizes functions such as user management and remote maintenance.IPMB is based on I ²The universal serial bus of C, flank speed 400kbps.Wherein, two blocks of SMM plates respectively as primary and backup, go wrong to reach a SMM plate, can be substituted the purpose of main board by standby plate.

In the existing IPMI system, to the monitoring of front and back plate as shown in Figure 2, the BMC module of front card is mended structure according to opening up of star to link to each other by the IPMB bus with the SMM plate, back card/back board does not have the BMC module, but the BMC module of front card can monitor and control that promptly the monitor message on the back card/back board all is reported to the BMC module of front card to back card/back board.

Described star is opened up and is mended structure as shown in Figure 3, the BMC on every veneer with lead with between CMM plate and the standby CMM plate I being arranged all ²C-channel links to each other, and makes that the IPMB bus between different veneers and the CMM is separate, does not interact, and is promptly separate with the data transmission channel of primary and backup CMM plate.Wherein front card has the core texture of BMC module, and back card/back board does not have the core texture of BMC module, monitoring information can only be reported front card BMC module.

Along with ATCA (Advanced Telecommunication Computing Architecture, high level communication calculates member) development of platform and becoming stronger day by day of function, some back card/back boards no longer have been the accessory structures of front card, but as one independently feature board appear in the machine frame, its effect and status and front card equality are so monitor comprehensively and effectively and management is very important back card/back board.And by above-mentioned narration as can be known, because back card/back board does not have the core texture of BMC module, in back card/back board function complexity, be difficult to back card/back board is carried out comprehensively, effectively and timely monitors and manages.

Summary of the invention

The object of the present invention is to provide the monitor of rear card board in a kind of intelligent-platform management interface system.

The objective of the invention is to be achieved through the following technical solutions:

Monitor of rear card board in a kind of intelligent-platform management interface system, this device comprises the baseboard management controller BMC module that is arranged on the back card/back board, the described BMC module that is arranged on the back card/back board links to each other with the ambient systems administration module by Intelligent Platform Management Bus IPMB, working status parameter on the back card/back board is reported the ambient systems administration module by described IPMB bus, described be arranged on the back card/back board the connected node of BMC module on the IPMB bus for the shared node of the connected node of BMC module on the IPMB bus of front card.

The described CPU that is arranged at the back card/back board at BMC module on the back card/back board and its place passes through I ²C and serial ports carry out communication.

The described BMC module that is arranged on the back card/back board will be redirected to outside serial port connector with the serial ports of CPU communication.

The described BMC module that is arranged on the back card/back board comprises:

Voltage monitoring and control circuit, the supply power voltage state of monitoring back card/back board, and the power-on and power-off of control back card/back board side.

The described BMC module that is arranged on the back card/back board comprises:

Transducer and control circuit thereof, the monitoring of environmental temperature.

The described BMC module that is arranged on the back card/back board comprises:

Back card/back board slot number and printing board PCB version information are stored and reported to the single board information update module.

The described BMC module that is arranged on the back card/back board comprises nonvolatile memory, the manufacturing information and the system time daily record of storage back card/back board.

As above-mentioned, from technical scheme provided by the invention as can be seen, the present invention is connected on the IPMB bus by the BMC module is set on the back card/back board of function complexity, has realized the function of IPMI intelligent management platform has been strengthened in back card/back board independent monitoring and management.
