Abstract
The invention provides a method for realization of KVM-OVER-IP of a domestic Loongson CPU server with a BMC. The method comprises the following steps that: a DVI signal is output by a BMC and a north bridge of a north bridge communication controller; the DVI signal is converted into a digital signal and then the digital signal is input in the BMC; and after a video signal in the BMC is compressed by the BMC, the compressed signal is sent to a remote control host by a network; and a management interface of the BMC is logged in in the remote control host to carry out decompression and restoration on a content of a network packet, so that the KVM-OVER-IP function of the server can be realized. According to the invention, compared with the prior art, the provided realization method enables remote controlling to be visual and convenient, thereby substantially reducing the management difficulty of the server and lowering management cost; therefore the realization method is easy to popularization and application.
Description
Technical field
The present invention relates to field of computer technology, specifically a kind of KVM-OVER-IP implementation method of the homemade Godson cpu server with BMC.
Background technology
Along with the development of homemade Godson CPU, adopt the server of homemade Godson CPU also to be born in recent years, and will begin gradually to use in some special industries; Homemade Godson processor is the CPU of complete independent intellectual property right because of it; And its low-power consumption of tool, safe controllability advantages of higher has very high using value in some special industry; Adopt the server of homemade Godson processor also will progressively be applied; And on function, progressively dress to the X86 server, current high-end server all has the function of remote side administration, and this patent provides a kind of method that on homemade Godson server, realizes KVM-OVER-IP.
Summary of the invention
Technical assignment of the present invention is in the deficiency of prior art, and a kind of KVM-OVER-IP implementation method of the homemade Godson cpu server with BMC is provided.
Technical scheme of the present invention realizes by following mode; The KVM-OVER-IP implementation method of this a kind of homemade Godson cpu server with BMC; Its structure comprises the server master board with homemade Godson CPU, and a baseboard management controller BMC chip is set on mainboard, and its concrete implementation method is:
At first the DVI output signal conveys of north bridge is arrived the chip of DVI signal revolution word signal, the DVI signal is converted into the digital signal of 24bit;
Give the BMC chip of supporting digital signal input mode with digital signal that transforms and row field signal, send to long-range control host machine through after the compression of BMC through 100,000,000 management network ports through control BMC chip and with signal;
The administration interface of login BMC in long-range control host machine, compressed data packet carried out decompress(ion) after, just can control the KVM-OVER-IP function of realization server at far-end to server.
One storage chip EEPROM is set on the said mainboard; This EEPROM is connected with north bridge and BMC chip through the I2C bus; This EEPROM is used to preserve the configuration information of general DVI display, when BIOS starts, lets north bridge remove to read plate and carries eeprom content and can normally show; Behind switching display more, the BMC chip can remove to read new switching display configuration information and it is write among the EEPROM of mainboard.
The beneficial effect that the present invention is compared with prior art produced is:
The KVM-OVER-IP implementation method of a kind of homemade Godson cpu server with BMC of the present invention is designed with the BMC chip on server master board; Realize functions such as the remote side administration of server master board monitoring and KVM-OVER-IP; Let the keeper can be in machine room, server is comprehensively controlled, comprise the operation of chip level such as BIOS setting, configuration array long-range just can the realization; For controlling of server just looks like to control local computer; Intuitively convenient, greatly reduce the server admin difficulty, reduce management cost.
Description of drawings
Accompanying drawing 1 is a realization block diagram of the present invention.
Embodiment
Specify below below in conjunction with accompanying drawing the KVM-OVER-IP implementation method of a kind of homemade Godson cpu server with BMC provided by the present invention being done.
For realizing all controllers power of server through network, make the keeper can be as removing management server in any place in machine room from the long-range this locality that moves on to.A kind of KVM-OVER-IP implementation method of the homemade Godson cpu server with BMC is provided at present, and its hardware comprises the server master board with homemade Godson CPU, and a baseboard management controller BMC chip is set on mainboard, and its concrete implementation method is:
At first the DVI output signal conveys of north bridge is arrived the chip of DVI signal revolution word signal, the DVI signal is converted into the digital signal of 24bit;
Give the BMC chip of supporting digital signal input mode with digital signal that transforms and row field signal, after overcompression, send to long-range control host machine by 100,000,000 management network ports through software and hardware control BMC chip and with video data bag and keyboard and mouse data;
The administration interface of login BMC in long-range control host machine, compressed data packet carried out decompress(ion) after, just can control the KVM-OVER-IP function of realization server at far-end to server.
Because all can be among the general video card VBIOS through the configuration information of I2C bus reading displayed device; When finding that display is not the DVI interface display, can not allow north bridge output DVI signal; When can cause us with common VGA interface display like this, north bridge is not exported the DVI signal, for head it off; So a storage chip EEPROM is set on mainboard; This EEPROM is connected with north bridge and BMC chip through the I2C bus, and this EEPROM is used to preserve the configuration information of general DVI display, when BIOS starts, lets north bridge remove to read plate and carries eeprom content and can normally show; Behind switching display more, the BMC chip can remove to read new switching display configuration information and it is write among the EEPROM of mainboard.
Embodiment: shown in accompanying drawing 1; To adopt Godson 3A processor, RS780 and RB700 chipset, the server of ASPEED 2050 BMC are explanation below example is done below; Wherein the SiI1161 chip is a DVI signal revolution word signal chip, and the ADV7125 chip is the DA conversion chip.
When BIOS starts; BMC can communicate by letter with north bridge and avoid occurring simultaneously the visit to the DDC eeprom chip; After north bridge has read the content of DDC EEPROM; Can export 3 pairs of DVI differential signals and a pair of differential clock signal to the SiI1161 chip, the SiI1161 chip transfers the DVI differential signal of input the digital signal of 24bit to, and produces row field signal; Digital signal after the conversion is connected to DA conversion chip ADV7125 on the one hand, is converted into the corresponding simulating rgb signal and cooperates the row field signal that SiI1161 produced to output to the VGA display interface; The digital signal and the row field signal of SiI1161 generation simultaneously are input to the BMC chip; ASPEED 2050 chips are supported digital signal input mode; Under the software and hardware control of 2050 BMC chips; To the compression of packing of shows signal and the keyboard and mouse signal of input, manage network interfaces through 100,000,000 nets and will send to machine remote management in the information of distal displayed, the flexecutive passes through browser logon server administration interface; To realize the management of server is controlled through the packet decompress(ion) of network transmission.And be connected through USB interface between BMC and south bridge, this USB interface is to be used to realize the virtual and synchronizing function to USB device.
