Description

Method and system for updating default configuration of hard disk backboard

Technical Field

Background

The hard disk backboard determines the number of the supported hard disks of the server and supports hot plug of the hard disks. The hard disk backboard prevents the direct connection of multiple cables between the hard disk and the main board, so that the internal wiring is simpler, and the heat emission blocking degree of the box body is reduced. Therefore, the hard disk backboard is widely applied to large-scale servers. The existing server market has more requirements on the configuration of the hard disk backboard, in order to meet the requirements of different clients as much as possible, the backboard with different uplink configurations, different structures and different firmware needs to be designed for research and development (the firmware in the backboard mainly refers to CPLD FW and is generally changed because of different uplink configurations), if the requirements of different configurations can multiplex the hardware design and the structural design of the same backboard, only the CPLD FW in the backboard needs to be changed; at this time, the code can be input to the CPLD in a dial mode, and the CPLD adapts different configurations in the code according to different dial values, so that the aim that different uplink configurations can multiplex the same hardware backboard is achieved, and the development task amount of engineers is reduced.

In order to achieve normalization of backboard with different uplink configurations, different structures and different firmware, the current implementation method is to complete allocation of different dialing codes with different uplink configurations in the initial stage of project planning. Specifically, a dial switch is added on the backboard board card, and the high-low level of the dial is input to a GPIO PIN PIN of the CPLD; the CPLD selects different uplink configuration analysis modes according to different levels of the GPIO PIN PINs, and completes information analysis conversion; therefore, the CPLD FW of one edition and one hardware backboard are compatible with different configuration requirements.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

The following explains key terms appearing in the present invention.

BMC, execution server remote management controller, english name Baseboard Management controller. The method can perform firmware upgrade, check machine equipment and other operations on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller and RAM for data storage, flash memory for non-volatile data storage, and firmware to provide basic remote manageability in terms of secure remote reboot, secure re-power-up, LAN alerting, and system health monitoring. In addition to the basic IPMI and system operation monitoring functions, the mBMC can also enable BIOS flash element selection and protection by storing the previous BIOS using one of the 2 flash memories. For example, when the system fails to boot after a remote BIOS upgrade, the remote administrator may switch back to the previously-working BIOS image to boot the system. Once BIOS is upgraded, the BIOS image can be locked, so as to effectively prevent virus from invading it.

The I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips corporation. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus transfer of data and generate a clock to open the transfer device, where any addressed device is considered a slave device. If the host computer is to send data to the slave device, the host computer firstly addresses the slave device, then actively sends the data to the slave device, and finally the host computer terminates the data transmission; if the host is to receive data from the slave, the slave is addressed by the master first, then the host receives data sent by the slave, and finally the host terminates the receiving process. In this case, the host is responsible for generating the timing clock and terminating the data transfer.

The complex programmable logic device CPLD adopts programming technologies such as CMOS EPROM, EEPROM, flash memory, SRAM and the like, thereby forming the programmable logic device with high density, high speed and low power consumption.

The intelligent platform management interface (Intelligent Platform Management Interface is IPMI) can span different operating systems, firmware and hardware platforms, and can intelligently monitor, control and automatically report the operation status of a large number of servers so as to reduce the cost of the server system.

The Flash storage area available to the UFM user is a nonvolatile memory, and the stored data cannot be lost after power failure.

FIG. 1 is a schematic flow chart of a method of one embodiment of the invention. The execution body of fig. 1 may update a system for default configuration of a hard disk back plate.

As shown in fig. 1, the method includes:

step 110, constructing a communication link between the complex programmable logic device and the baseboard management controller, and receiving and storing dial information sent by the baseboard management controller through the communication link by the complex programmable logic device;

step 120, searching target configuration data corresponding to the dialing information according to a locally stored configuration list, wherein the configuration list comprises configuration data corresponding to various dialing information;

and 130, analyzing the target configuration data, and refreshing the uplink configuration of the hard disk backboard according to the target configuration data.

In order to facilitate understanding of the present invention, the principle of the default configuration updating method for the hard disk backboard according to the present invention is used in the following, and the default configuration updating method for the hard disk backboard provided by the present invention is further described in conjunction with the process of updating the default configuration of the hard disk backboard in the embodiment.

Specifically, the method for updating the default configuration of the hard disk backboard comprises the following steps:

s1, constructing a communication link between a complex programmable logic device and a baseboard management controller, and receiving and storing dial information sent by the baseboard management controller through the communication link by the complex programmable logic device.

Connecting the complex programmable logic device with the baseboard management controller by using an I2C bus; the encryption program of the complex programmable logic device sends verification information to the baseboard management controller, the verification information is used for verifying the identity of an information source, and the verified information has the authority of writing into a register. The complex programmable logic device synchronously backs up the dialing information written into the register by the baseboard management controller to a nonvolatile memory area available to the user, wherein the dialing information covers the historical dialing information in the nonvolatile memory area available to the user.

The communication connection is established between the complex programmable logic device and the baseboard management controller, so that the baseboard management controller writes the dial information into the register of the complex programmable logic device by using the I2C instruction. Thus, the manual action of manual dialing is replaced. Meanwhile, the complex programmable logic device synchronously backs up the dialing information written into the register by the baseboard management controller to a nonvolatile memory area (UFM) available for a user, so that the dialing information loss caused by power failure is avoided. The dialing information covers the historical dialing information in the non-volatile memory area available to the user, and the dialing information in the non-volatile memory area available to the user can be guaranteed to be always up to date. Meanwhile, the embodiment can avoid misoperation by adding the identity verification function into the complex programmable logic device, and only the dialing information with verification information is accepted.

S2, searching target configuration data corresponding to the dialing information according to a locally stored configuration list, wherein the configuration list comprises configuration data corresponding to various dialing information.

Reading a pre-stored configuration list from a non-volatile memory area available to a user, and reading dial information from a register; and searching target configuration data corresponding to the dial information from the configuration list.

When the backboard is planned, different configurations to be adapted to the backboard are planned and completed, and a configuration list is formed, wherein the specific configuration list forming process is the prior art and is not described in detail. The configuration list is shown in table 1:

table 1 uplink configuration examples with different dialing codes

Dial configuration	Upward goingConfiguration list
		0000 (default)	Configuration 1 (default)
0001	Configuration 2
		0010	Configuration 3
0011	Configuration 4
		…	…

Configuration list in this embodiment, the configuration list is saved to a nonvolatile memory area available to the user, so that the complex programmable logic device is convenient to take while the data is not lost. The CPLD writes default configuration (such as 0000) into the UFM in a burning way when the board card is punched for the first time; the CPLD comprises two registers, when the CPLD is powered on for the first time and uses the dialing information, the information is firstly read from the UFM and stored in the register 2 for use. The default state of the internal register 1 of the CPLD is set to be the default configuration (0000), and when the BMC rewrites the dial information of the register 1 to 0001 through a communication instruction in the operation process of the CPLD, the CPLD writes 0001 into the register 2 and analyzes the uplink information of the configuration 2 (the configuration 2 corresponds to the dial 0001) by using the register numerical value; meanwhile, the CPLD synchronizes the register dial information 0001 to the UFM for storage. Under the condition that power is not lost, the CPLD can directly read the dial information from the register 2, if the CPLD is powered down in the operation process, the CPLD cannot read the dial information in the register, the dial information needs to be read from the UFM, and meanwhile, the read dial information is synchronized to the register 2.

S3, analyzing the target configuration data, and refreshing the uplink configuration of the hard disk backboard according to the target configuration data.

Analyzing the target configuration data, importing the analysis result into the hard disk backboard, and refreshing the configuration parameters of the hard disk backboard. The CPLD analyzes each configuration parameter item and corresponding parameter value in the target configuration data, and leads the parameter value corresponding to each configuration parameter item into the hard disk backboard control chip to realize the configuration refreshing of the hard disk backboard.

In another embodiment of the present invention, please refer to fig. 2, the present embodiment provides a method for updating a default configuration of a hard disk back plate, which includes the following steps:

s1, presetting client requirements and IPMI (intelligent platform management interface) dialing instructions corresponding to various dialing information by the BMC, and arranging the various dialing information and the client requirements corresponding to the various dialing information into a requirement list.

On the basis, the embodiment provides a preferred implementation manner, namely, the BMC outputs and displays the requirement list through a BMC WEB page, and the client requirement comprises a plurality of requirement keywords.

Through corresponding various dialing information with the client requirement, the production line operator searches the target requirement keyword in the BMC WEB page or inputs the requirement keyword, and the BMC can automatically search the corresponding dialing information. The method is convenient to operate, and the requirement on the working experience of the production line operator is reduced.

S2, receiving dialing information selected by a user according to the requirement list, and writing the dialing information into a register of the complex programmable logic device through a communication link, wherein the dialing information is used for guiding the complex programmable logic device to refresh the configuration of the hard disk backboard.

The BMC writes the dialing information selected by the user into the register of the complex programmable logic device through the I2C bus, and replaces the existing method for generating the dialing information to the complex programmable logic device through the dialing switch. Compared with a dial switch, the BMC-based method provided by the embodiment is higher in automation degree, and the space of a hardware hard disk backboard is not required to be increased.

The following provides a default configuration updating method for a hard disk backboard in an actual application scene:

1. at the initial stage of project planning, completing list planning of matching different dialing codes with different uplink configurations;

2. firstly burning default configuration of dialing codes into CPLD UFM registers through CPLD FW;

3. in the I2C link between BMC and CPLD, adding a command: the BMC can write the currently required dial configuration into a CPLD register through the command, and the CPLD automatically synchronizes the register information into the UFM;

4. if the default configuration is selected during shipment, the shipment can be directly carried out; if other configurations are selected during shipment, when the backboard is assembled on the production line, a production line operator can issue a command under the system according to an operation instruction provided by a BMC engineer, and the configuration information required at present is written into an internal register of the CPLD through an I2C link of the BMC and the CPLD, and the CPLD judges which type of uplink information needs to be analyzed according to the value of the register to finish the reset of the dialing information; meanwhile, the CPLD synchronously stores the information written into the register by the BMC into the internal UFM, so that the CPLD is ensured not to lose the power failure information.

According to the technical scheme, manual dialing manual actions of a production line operator are eliminated, error rate in assembling a machine is reduced, and working efficiency in assembling the production line is improved.
