Detailed Description
So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
Fig. 1 is a schematic flow chart illustrating an implementation of a signal control method based on power line communication according to an embodiment of the present invention; applied to a server; the server includes: the system comprises a BMC module and a relay module connected with the BMC module; as shown in fig. 1, the method includes:
step 101: the BMC module acquires a management signal corresponding to the server and sends the management signal to the relay module;
in practical applications, the BMC module and the relay module are respectively integrated in different boards, for example, the BMC module is integrated in a motherboard of the server, and the relay module is integrated in other boards except the motherboard.
Step 102: and after receiving the management signal, the relay module modulates the management signal and sends the modulated management signal to a power line network corresponding to the server, so that the BMC module is accessed to the power line network corresponding to the server through the relay module.
Therefore, the embodiment of the invention realizes the power line carrier networking of the BMC module in the server, namely, the BMC module in the server is accessed into the power line network corresponding to the server, so that the BMC module does not need to be additionally networked independently, the problems of equipment and bandwidth resource waste and complicated machine room circuit layout caused by the traditional wired networking are solved, and the construction cost of networking is reduced. Meanwhile, in practical application, because the BMC module provided by the embodiment of the invention can monopolize the power line network of the machine room corresponding to the server, the network environment of the BMC module is relatively stable, and the transmission rate can reach more than 200Mbps, thereby effectively avoiding the problems of unstable communication link and insufficient bandwidth caused by short-distance wireless communication networking of the BMC module.
In addition, since the BMC module is accessed to the power line network corresponding to the server in the embodiment of the present invention, a manager can access the BMC module through the power line network as long as the manager accesses the terminal to the power line network through the power modem, that is, as long as a power socket in the same power supply system as the server exists near the manager, the manager can directly access the terminal to the power line network through the power modem to access the BMC module.
In this embodiment, the relay module may not only forward the received management signal sent by the BMC module to the power line network corresponding to the server, but also may receive a management control signal sent by the power line network, and forward the management control signal according to the attribution of the management control signal, and specifically,
the relay module receives a management control signal corresponding to the server from the power line network;
and the relay module detects the management control signal and selects a processing strategy corresponding to the management control signal according to a detection result.

and when the detection result represents that the management control signal is a signal corresponding to the relay module, the relay module selects a second processing strategy so as to locally process the management control signal.
In practical application, because the power supply of the BMC module does not depend on an operating system of the server, but directly supplies power through a power supply, when the BMC module fails, such as the BMC module cannot be accessed through IP (Internet protocol) or part of management functions are abnormal, a manager can only go to a machine room to manually power off and then recover the failed server, and thus, inconvenience is brought to operation and maintenance work; therefore, in the embodiment of the present invention, the power supply module of the server provides power support for the BMC module, so as to avoid the above problem; specifically, the server further comprises a power supply module; the power supply module is connected with a power line network corresponding to the server; the method further comprises the following steps:

For example, the on-off of a power supply line between the power supply module and the BMC module is controlled, and then the on-off of the BMC module is controlled.
In practical applications, in order to enable a manager to query and control the relay module, the method further includes: and setting a network identifier corresponding to the relay module so that a user can acquire the state information corresponding to the relay module according to the network identifier. For example, an IP address is configured for the relay module, thus enabling a manager to access the configured state through the IP address corresponding to the relay module.
In this way, since the power supply module of the server provides power support for the BMC module in the embodiment of the present invention, when a manager finds that the BMC module in the server fails, the manager does not need to perform a manual power-off reset operation on the failed server in a machine room, but can remotely and directly perform power reset on the server to recover a temporary failure of a corresponding module, thereby improving the processing speed of such a failure.
In addition, since the embodiment of the present invention further configures a network identifier, such as an IP address, for the relay module, a manager can access the IP address corresponding to the relay module to obtain the status information of the relay module, thereby implementing on/off of the power supply line of the BMC module of the control server.

Another way of dividing each processing unit in the server is given below, specifically as in example two.
Example two
In this embodiment, an independent power supply board card having a power line communication function and a repeater function, that is, a PLC repeater board card, is added between a power supply of a server and a motherboard, that is, between the power supply and a board card where a BMC module is located; on one hand, the PLC relay board card is connected with a BMC module integrated on a mainboard, receives network signals such as out-of-band management Web interface information and the like sent by the BMC module, modulates the network signals such as the out-of-band management Web interface information and the like, and transmits the network signals to a power line network of a machine room where a server is located through a power supply of the server, so that a manager using a terminal power modem at a far end can acquire information from the power line network and interact with the BMC module; on the other hand, when the BMC module fails, a manager may directly access the PLC relay board card through the power line network, and control the PLC relay board card to switch off the power supply to the motherboard, that is, the power supply of the BMC module, and then restore the power supply, so as to implement remote power reset of the failed BMC module.
FIG. 3 is a block diagram illustrating an implementation of a server according to an embodiment of the present invention; as shown in fig. 3, the server includes: a PLC relay board 31, a main board 32, and a power supply 33; the PLC relay board card 31 is independently powered by the power supply 33 and does not depend on a mainboard. Wherein, the PLC relay board card 31 includes: a power relay module 311, a PLC module 312, and firmware 313; the motherboard 32 comprises a power supply circuit 321 and a BMC module 322; in particular, the amount of the solvent to be used,
the PLC module 312 communicates with the BMC module 322, and modulates the out-of-band management network information sent by the BMC module 322 into a power supply line of a machine room corresponding to a server through the power supply 33, that is, modulates the out-of-band management network information sent by the BMC module 322 into a power line network corresponding to the server through the power supply 33; therefore, managers can demodulate and acquire the out-of-band management network information from any socket in the same power supply system with the machine room through the portable power modem; similarly, the manager can send an operation command such as inquiry, control, etc. to the BMC module 322 through the power supply 33 and the PLC module 312, specifically, the operation command such as inquiry, control, etc. is modulated into the power line network through the modem, demodulated by the PLC module 312 of the server, and transmitted to the BMC module 322. And communication interaction between managers and BMC modules of servers of the machine room is realized.
In practical application, the PLC relay board 31 may also configure its own IP address to allow a manager to access the configuration; the specific data path is the same as the communication process described above, and the access process still performs power line communication interaction via the PLC module 312.
The power relay module 311 is configured to connect the power supply 33 and the power supply circuit 321 of the motherboard 32, so as to achieve the purpose of providing power support for the BMC module 322 through the power supply 33. Here, when the administrator finds that a fault occurs in a server BMC module 322, such as an access failure or a partial functional failure, the firmware 313 in the PLC relay board 31 can be accessed through the IP address of the PLC relay board 31, and the power relay module 311 is controlled by the firmware 313 to cut off the power supply from the power supply 33 to the power supply circuit 321, and then, the power relay module is recovered later. In this manner, a remote power reset/restart process is realized. Here, the power supply circuit 321 may provide power support for the BMC module 322 only through the power relay module 311, or may provide power support for the motherboard 32 where the BMC module 322 is located while providing power support for the BMC module 322 through the power relay module 311.
In practical applications, the power supply line of the PLC module 312 may be integrated on the PLC relay board 31; the connection mode between the PLC module 312 and the BMC module 322 may be a flat cable connection mode, or an RJ-45 common network cable connection mode; the communication between the PLC module and the firmware 313 may be implemented through a bus of the PLC relay board 31. Further, the PLC module 312 can modulate the information sent by the BMC module 322 and the information sent by the firmware 313 onto a powerline carrier, and transmit the modulated information to a powerline network of a machine room where the server is located from the power source 33. Likewise, the PLC module 312 can also demodulate a network signal matched with the server transmitted from the power line network by the power supply 33 and transmit the network signal to a corresponding communication object, for example, the BMC module 322 or the firmware 313.
The firmware 313 is a firmware system of the PLC relay board 31 itself, and the firmware 313 may configure an IP address for a manager to access the Web. The administrator can adjust the configuration of the PLC relay board card 31 by using the IP address, and control the power relay module 311 to turn on or turn off the power supply to the power supply circuit 321 of the server motherboard; here, the information exchange between the firmware 313 and the administrator is also performed by the power line communication system via the PLC module 312.
The power relay module 311 may be implemented by a common controlled power relay; specifically, the power relay module 311 is configured to receive an instruction of the firmware 313, and perform an on-off operation on the power supply circuit 321 of the motherboard according to the instruction. The instruction is an instruction sent by a terminal corresponding to a manager through a power line network, a power supply and a PLC module.
The power supply 33 is a power supply component of the server and is used for connecting each board card of the server, such as the main board 32 and the PLC relay board card 31, with a circuit of external power. Here, the power supply 33 is generally a two-way power supply. In the embodiment of the invention, two power supplies can supply power to the mainboard only through the PLC trunk board card. Meanwhile, the power carrier signal is also transmitted to the machine room power line network through the power supply.
The power modem provided by the embodiment of the invention is a portable external power line communication modem held by a server manager. Here, the modem can perform matching communication with all the PLC modules in the server corresponding to the modem via the power line network, and as long as a manager can access any power socket in the same power supply system as the machine room, access control to the module BMC of the server can be achieved.
The foregoing is merely an example of the embodiments of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the embodiments of the present invention, and these modifications and decorations should also be regarded as the protection scope of the embodiments of the present invention.
