Description
Technical field
The present invention relates to computer communication field, specifically utilize a kind of method that realizes remote server administration based on Video Decoder Design.
Technical background
In current server product system, server cluster work, user is in order to understand more closely the running status of server, require server to there is the function of bottom management, comprising: local and remote hardware diagnostic, control desk support, configuration management, hardware management and fault eliminating and remote management capability etc.Wherein remote management capability is the effective means that realizes user and server system management by synchronization.
The Remote WEB way to manage based on BMC chip of main flow is used widely at present, it is by the management circuit of design specialized on server master board, the mainboard information of management circuit being collected by management network port sends client to, as information such as temperature, rotation speeds of the fan.But along with user is more and more higher to the demand of server Long-distance Control, management, in server system design, above-mentioned Remote WEB way to manage cannot Real-time Obtaining remote server action pane, such as the program that server is moved, install, debug, arrange etc., Remote WEB way to manage cannot realize the real-time monitoring of server operation service, and this has just brought great difficulty to the telemanagement of server operation service; How to allow and realize server system when realizing WEB way to manage, realize real-time monitoring and the user side operation of server operation service, become one of important indicator of evaluation server system manageability.
In order to meet increasing server user's requirement, for above problem, by analysing in depth, applicant has summed up a kind of method that realizes remote server administration based on Video Decoder Design, by original WEB way to manage, realize server for remote management function and backup that can permanent automatic preservation long-distance user record data.
Summary of the invention

3. the real-time controlled processing unit of data is connected and is taken over after data flow VGA2 passage, being that the real-time controlled processing unit of data is connected to display card access PCIE(x16) data on groove and clock etc. are all on holding wires, through data real-time controlled processing units to the buffering of data drive, signal compensation, then pass through the PCIE(x16 of the real-time controlled processing unit of data) protocol-decoding, recoding generates compression VGA video data signal.
4. the compression VGA video data after rearranging sequentially sends DRAM buffer unit to by the real-time controlled processing unit of data again.
5. in common WEB way to manage, on BMC managing chip, read and process DRAM buffer unit, by data cached, by network, send Terminal Server Client to, realize obtaining of Terminal Server Client video data.This signal is through video data change backup units simultaneously, and effectively monitoring in real time, backup user operation records change.
Step
in, branch adopts fpga chip to realize fast data buffer branch in controlling, data after branch and real-time VGA show that data are consistent, on hardware, cannot distinguish device type, therefore adopting the real-time controlled processing unit of data is by identification equipment ID that data flow VGA2 is decoded, when recognizing video card ID, think and have external display card access in system.
Step
with
in, the real-time controlled processing unit of data, by receiving user's instruction, is connected adapter data flow VGA2 passage.Through data real-time controlled processing units to the buffering of data drive, signal compensation, then pass through the PCIE(x16 of the real-time controlled processing unit of data) protocol-decoding, recoding generates compression VGA video data signal.The real-time controlled processing unit of data starts the processing of VGA data by receiving user's instruction, to reduce power consumption and the load of system; After branch due to data, inevitably have decay, the reflection of the driving force of data, the real-time controlled processing unit of data cushions driving to data, signal is carried out to data balancing and high frequency compensation driving simultaneously, improves the driving force of signal; To the data of VGA, from PCIE extracts, need to carry out discretization to data and extract compression, the requirement while meeting resolution, reduce as far as possible data volume.
Step
in, compression VGA video data after rearranging sequentially sends DRAM buffer unit to by the real-time controlled processing unit of data again, DRAM buffer unit is external DDR3 particle module, is used for depositing the VGA data after compression, as the buffer area of video data and BMC chip.
Step
in, in WEB way to manage, on BMC managing chip, read and process DRAM buffer unit, be about to data cachedly by network, send Terminal Server Client to, realize obtaining of Terminal Server Client video data.On BMC managing chip, read the video data leaving in DRAM buffer unit, carry out package, object transmission simultaneously using these data as network data, assurance object client can be decoded accurately, the video data on network.
In order to improve the transmission reliability of data, adopt the direct mapping mode of address space, from the base address data of buffer memory, start to deposit in successively the homepage storage area of flash memory.When needs are checked, directly from flash memory, read successively video incremental data, improve the reliability of management data.
In order to improve the transmission reliability of data, can also adopt address space Linear Mapping mode, from the base address data of buffer memory, start to deposit in successively flash memory storage region.
In order to improve the bulk transfer of data block, realize the quick transmission of data, from data access mechanism, consider, adopt " first in first out " heap stack mode---data cached storage stack distribution mode, be that data are write sequence address employing mode from big to small, data are read sequence address and are adopted mode from small to large, and read-write can walk abreast.
Video data buffer unit adopts dsp chip to realize " first in first out " heap stack mode of video compression data.
Beneficial effect of the present invention is: this novel server admin architecture has the characteristics such as intellectuality, flexible compatibility and extended attribute.Not only meet the long-range management function of video, realize the requirement of server operation service state real-time update, more improved the management of performance stability of system.
