Description
Technical Field
The present invention relates to an electronic digital data processing system, and more particularly, to an inventory management setting system.
Background
A manufacturer of a servo system adjusts functions of a plurality of components of the servo system, such as a backplane (backplane), a chassis (chassis), a chassis fan, a heat sink, and the like, and generates a plurality of motherboards to be installed in the servo system according to the specification requirements of a client. For example, if two different specifications of the motherboards are different, the chassis fan operates in a first and a second speed range, respectively, then one of the motherboards with the chassis fan operating in the first speed range constitutes a Stock Keeping Unit (SKU), and the other of the motherboards with the chassis fan operating in the second speed range constitutes another different stock keeping unit, so the manufacturer of the servo system needs to establish two sets of stock keeping parameter codes for the two stock keeping units respectively constituted by the two batches of motherboards, where each set of stock keeping parameter codes includes, for example, a stock keeping number (SKU ID), a fan control table (fan table), a chassis code (chassis ID), and so on.
Referring to fig. 1, the conventional motherboard includes a south bridge 11 having a general Purpose Input/Output (GPIO) control circuit 13, a Baseboard Management Controller (BMC) 12 electrically connected to the south bridge 11 and controlling and managing servo components, and a Basic Input/Output unit (BIOS) 14 electrically connected to the south bridge 11 and communicating with the BMC 12 through the south bridge 11, assuming that N types of motherboards required by a client constitute N stock Management units, the BIOS 14 and the rom of the BMC 12 in each motherboard of the client store N sets of stock Management parameter codes, the N sets of stock Management parameter codes respectively correspond to the N stock Management units, and when the BIOS 14 executes a boot program, the BIOS 14 receives an instruction generated by the GPIO control circuit 13 to instruct the BMC The data designation signal corresponding to the specification of the board reads the corresponding inventory management parameter code from the ROM, and displays the corresponding inventory management parameter code for the user.
After waiting for a predetermined time (the predetermined time is the time required for the initialization of the bmc 12), the bios 14 issues an instruction to the bmc 12 via the south bridge 11 to instruct the bmc 12 to read the corresponding inventory management parameter codes, so that the bmc 12 can control and manage the servo components according to the read inventory management parameter codes to complete the boot process.
However, the disadvantages of the motherboard in batch management are as follows.
First, when the customer adds different specifications to the motherboard to extend the (N +1) th inventory management unit, the bios 14 and the bmc 12 need to be re-manufactured, and manually write the corresponding inventory management parameter codes into the rom of the bios 14 and the bmc 12 one by one. However, the manufacturer usually wants to digest the motherboard that has not been shipped, and at this time, it is necessary to expend extra manpower to set the data designating signal, and verify and test whether the corresponding inventory management parameter codes are read by the bios 14 and the bmc 12.
Second, since the bmc 12 needs 40 to 60 seconds to initialize and waits for the initialization to complete and then receives the command to read which inventory management parameter code, the overall boot-up procedure takes a long time, and if the bmc 12 is halted, the boot-up procedure may not be completed normally.
Based on the above, the batch management of the conventional motherboards is obviously a method which is not very cost-effective.

[ detailed description ] embodiments
Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.
Referring to fig. 2, the inventory Management setting system 2 of the present invention conforms to the industry standard of Intelligent Platform Management Interface (IPMI), and includes a storage device 21, a remote server 24, and a motherboard 22.
The storage device 21 stores an inventory management parameter code corresponding to the motherboard specification, and a setting interface 23, the inventory management parameter code includes at least one setting data. In this embodiment, the configuration data is at least one of a stock keeping unit ID (SKU ID), a product ID, a version code (post banner) corresponding to, for example, a bios or bmc, a server chassis ID, and a server chassis string. The setting interface 23 is a Linux tool (Linux), which is executed in an operating system (not shown), and outputs at least one setting data of the corresponding inventory management parameter code in the storage device 21 according to a user input.
The remote server 24 has the inventory management parameter code and the configuration interface 23 connected to the bmc through a network.
The motherboard 22 includes an Electrically erasable Read-Only Memory (EEPROM) 223, a switch 224, a control chipset 225, a Basic Input/Output System (BIOS) 226, and a Baseboard Management Controller (BMC) 227.
Referring to FIG. 3, the EEPROM 223 has a predetermined memory allocation associated with a start address and a bit length corresponding to a plurality of memory segments, each corresponding to different types of setting data. In the present embodiment, the eeprom 223 is implemented by a Motherboard field-replaceable unit (Motherboard FRU) soldered to the Motherboard 22.
Furthermore, the eeprom 223 has a memory space of 255 bits, for example, each memory segment is obtained by adding the bit length space occupied by the previous setting data to the start address of the previous setting data, for example, sequentially: the inventory management identification code occupying 1 bit length space from the starting address of 0, the product identification code occupying 2 bit length space from the starting address of 1, the version code of the corresponding basic input and output unit and the baseboard management controller occupying 28 bit length space from the starting address of 3, and the like, until the 255 bit space is used up.
Referring to fig. 2, the switch 224 has a first end 2241, a second end 2242, a third end 2243 and a control end 2244 electrically connected to the eeprom 223, and the control end 2244 is controlled to switch the first end 2241 to selectively connect the second end 2242 or the third end 2243, i.e. switch the first end 2241 and the second end 2242 between conducting and non-conducting states, and switch the first end 2241 and the third end 2243 between conducting and non-conducting states, when the first end 2241 and the second end 2242 are conducting states, the first end 2241 and the third end 2243 are non-conducting states, and when the first end 2241 and the second end 2242 are non-conducting states, the first end 2241 and the third end 2243 are conducting states. In detail, the switch 224 is a switch located on an Inter-Integrated Circuit Bus (I2C Bus), and conforms to the Bus transmission protocol of the Inter-Integrated Circuit.
The control chipset 225 is electrically connected to the second end 2242 of the switch 224 and electrically connected to the storage device 21 for receiving the setting data of the inventory management parameter code from the storage device 21. In the embodiment, the control chipset 225 is a Platform Controller Hub (PCH) so as to be compatible with the processor architectures of X86 and non-X86. Moreover, the control chipset 225 performs bus transmission with the EEPROM 223 through the switch 224.
The bios 226 is electrically connected to the control chipset 225 and records the predetermined memory configuration. The basic input/output unit 226 and the control chipset 225 conform to the general Purpose input/output (GPIO) bus transmission protocol.
The bmc 227 is electrically connected to the control chipset 225 and the switch 224, and is configured to communicate with the bios 226 and the setting interface 23 via an intelligent platform management interface (IPMI command), and accordingly send a control signal to the control end 2244 of the switch 224, so that the first end 2241 of the switch 224 is conducted between the second end 2242 and the third end 2243. And the bmc 227 also records the default memory configuration. Wherein, the board management controller 227 and the control chipset 225 conform to the Low Pin Count (LPC) bus transmission protocol; moreover, the BMC 227 performs bus transfer of internal integrated circuit with the EEPROM 223 through the switch 224.
Referring to fig. 4 and 5, a first embodiment of the inventory management setting system 2 of the present invention is: when the user checks and inputs what kinds of setting data are to be updated on the setting interface 23 of the storage device 21, the data setting method executed by the inventory management setting system 2 includes the following steps.
In step 31, the setting interface 23 obtains the setting data corresponding to the to-be-updated data from the inventory management parameter code according to the user's input, and outputs the setting data to the control chipset 225.
In step 32, when the first end 2241 and the second end 2242 of the switch 224 are turned on, the control chip set 225 writes the inventory management parameter codes into the eeprom 223 through the switch 224 according to the predetermined memory configuration.
In step 33, the setting interface 23 issues a second switching command to the control chipset 225 and outputs the second switching command after the control chipset 225 completes writing. The second switching command instructs to turn on the first terminal 2241 and the third terminal 2243 of the switch.
In step 34, the bmc 227 receives the second switching command, and then sends a control signal to the control terminal of the switch 224 to turn on the first terminal 2241 and the third terminal 2243 of the switch 224.
In step 35, the BMC 227 updates the previously stored configuration data by loading the configuration data of the inventory management parameter code from the EEPROM 223 through the switch 224 according to the default memory configuration.
In step 36, after the refresh is completed, the bmc 227 sends a control signal to the control terminal 2244 of the switch 224 to turn on the first terminal 2241 and the second terminal 2242 of the switch 224. Thus, when the user updates several setting data by using the setting interface 23 again (i.e. repeating step 31), the control chipset 225 can write the inventory management parameter code into the eeprom 223 through the switch 224.
Therefore, when a user needs to add function adjustment of the motherboard, the manufacturer of the motherboard only needs to set the configuration via the configuration interface 23, the control chipset 225 writes the configuration data into the memory segment corresponding to the eeprom 223 according to the default memory configuration, and the bmc 227 then obtains the updated inventory management parameter code from the eeprom 223 to control the servo components.
Referring to fig. 4 and 6, a second embodiment of the inventory management setting system 2 according to the present invention is described, which comprises the following steps, when the user updates the setting data through the setting interface 23 of the storage device 21, and then the system is powered on, and the motherboard 22 is powered on.
In step 41, the bios 226 updates the previously stored configuration data by loading the configuration data of the inventory management parameter codes from the eeprom 223 through the control chipset 225 and the switch 224 according to the predetermined memory configuration during the boot process.
In step 42, after the BIOS 226 loads the inventory management parameter codes from the EEPROM 223, a first switch command is issued and outputted via the control chipset 225. The first switch command instructs the first terminal 2241 and the third terminal 2243 of the switch 224 to be turned on.
In step 43, the bmc 227 sends a control signal to the control terminal 2244 of the switch 224 according to the indication of the first switching command, so as to turn on the first terminal 2241 and the third terminal 2243 of the switch 224.
In step 44, the BMC 227 updates the previously stored configuration data by loading the configuration data of the inventory management parameter code from the EEPROM 223 through the switch 224 according to the default memory configuration.
Therefore, when the motherboard 22 is turned on later, the bios 226 and the bmc 227 are loaded into the eeprom 223 according to the default memory configuration to store the corresponding inventory management parameter codes, and the manufacturer does not need to re-manufacture the bios 226 and the bmc 227. When the manufacturer wants to digest the inventory, it can also save the trouble of verifying and testing whether the BIOS 226 and the BMC 227 correctly obtain the corresponding inventory management parameter codes.
In addition, by the design of the switch 224, when the switch 224 is turned on at the first end 2241 and the second end 2242 of the switch 224, the bios 226 first reads the setting data of the inventory management parameter code and executes the boot program, and after the reading is completed, the first control command is sent, so that the bmc 227 controls the switch 224 to read the required setting data, even if the bmc 227 is initialized for a long time or is halted, the bios 226 still continues to complete the boot program.
Referring to fig. 7 and 8, a third embodiment of the inventory management setting system 2 of the present invention is similar to the first embodiment, except that the bmc 227 can also be connected to the remote server 24 via the network to receive the inventory management parameter codes from the remote server 24 for updating. And the third embodiment is: when the user checks and inputs what kinds of setting data are to be updated on the setting interface 23 of the remote server 24, the data setting method executed by the inventory management setting system 2 of the present invention includes the following steps.
In step 51, the configuration interface 23 of the remote server 24 obtains the configuration data corresponding to the desired update in the inventory management parameter code according to a user's input, and outputs the configuration data through the network.
In step 52, the bmc 227 receives the inventory management parameter codes from the remote server 24 and loads the configuration data of the inventory management parameter codes according to the default memory configuration for updating.
In step 53, the BMC 227 writes the inventory management parameter codes to the EEPROM 223 via the switch 224 according to the default memory configuration.
In step 54, the bmc 227 sends a control signal to the control end 2244 of the switch 224 after the writing is completed, so as to turn on the first end 2241 and the second end 2242 of the switch 224. Thus, when the user updates several setting data by using the setting interface 23 again (i.e. repeat step 51), the control chipset 225 can write the inventory management parameter code into the eeprom 223 through the switch 224.
Referring to fig. 7 and 9, a fourth embodiment of the inventory management setting system 2 of the present invention is described, which illustrates a data setting method executed when the host board 22 is powered on after the user updates the setting data through the setting interface 23 of the remote server 24, and the system is powered on, and includes the following steps.
In step 61, the BIOS 226 updates the previously stored configuration data by loading the configuration data of the inventory management parameter codes from the EEPROM 223 through the control chipset 225 and the switch 224 according to the default memory allocation while executing the boot-up procedure.
In step 62, after the BIOS 226 loads the inventory management parameter codes from the EEPROM 223, a first switch command is issued and outputted via the control chipset 225. The first switch command instructs the first terminal 2241 and the third terminal 2243 of the switch to be turned on.
In step 63, the bmc 227 sends a control signal to the control terminal of the switch 224 according to the indication of the first switching command, so as to turn on the first terminal 2241 and the third terminal 2243 of the switch 224.
In step 64, the BMC 227 updates the previously stored configuration data by loading the AMC code from the EEPROM 223 through the switch 224 according to the default memory allocation.
Thus, no matter the host board manufacturer or the client, the remote server 24 can be used to set the setting data of the inventory management parameter code, and transmit the setting data to the baseboard management controller 227 through the network, and the baseboard management controller 227 then receives the updated inventory management parameter code to control the servo components, and updates the EEPROM 223, so that the BIOS 226 and the baseboard management controller 227 can be loaded and read when the computer is powered on, thereby increasing the flexibility of updating the setting data during the inventory management process.
It should be added that, no matter the user updates the inventory management parameter code through the configuration interface 23 of the storage device 21 or the configuration interface 23 of the remote server 24, the bios 226 and the bmc 227 can be loaded and read and can be converted into txt file to be transmitted back to the storage device 21 or the remote server 24 for the confirmation of the supplier or the client without the need of human verification and testing.
In summary, the inventory management setting system of the present invention utilizes the preset memory configuration of the eeprom 223, the bios 226, and the bmc 227 to update the setting in a programmable manner, thereby providing the following advantages.
First, when the client has a requirement for additional motherboard function adjustment, or the motherboard manufacturer wants to digest the stock, the control chip set 225 writes (records) the eeprom 223 into the bios 226 and the bmc 227 only by setting the stock management parameter code on the setting interface 23 of the storage device 21 or the setting interface 23 of the remote server 24, so that the motherboard manufacturer does not need to manufacture the bios 226 and the bmc 227 again.
Secondly, by means of the switch 224, the bios 226 will read the setting data of the inventory management parameter code and execute the boot process, and then the bmc 227 reads the required setting data according to the first switching command control switch 224, even if the bmc 227 has an excessively long initialization time or is dead, the bios 226 will continue to complete the boot process, so as to achieve the purpose of the present invention.
The embodiments and examples of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments and examples, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
