Description

Method and system for updating default configuration of hard disk backplane

Technical Field

The invention relates to the technical field of server hard disk backplanes, in particular to a method and a system for updating default configuration of a hard disk backplane.

Background

The hard disk backboard determines the number of the hard disks supported by the server and supports hot plug of the hard disks. The hard disk backboard avoids direct connection of multiple cables between the hard disk and the main board, so that internal wiring is more concise, and the heat emission blocking degree of the box body is reduced. Therefore, the hard disk backplane is widely applied to large servers. At present, the server market has more requirements on hard disk backplane configuration, in order to meet the requirements of different customers as much as possible, backplanes with different uplink configurations, different structures and different firmware need to be designed (the firmware in the backplane mainly refers to CPLD FW, which generally changes due to different uplink configurations), and if the requirements of different configurations can reuse the hardware design and the structural design of the same backplane, only the CPLD FW in the backplane is needed to change; at the moment, the dial code can be input into the CPLD, and the CPLD adapts different configurations in the code according to different dial code values, so that the aim that different uplink configurations can reuse the same hardware backboard is fulfilled, and the development task load of engineers is reduced.

In order to realize normalization of backplanes with different uplink configurations, different structures and different firmware, the current implementation method is to allocate different dial codes to different uplink configurations at the initial stage of project planning. Specifically, a dial switch is added on a backboard card, and the high and low levels of dial are input into 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, different configuration requirements of a CPLD FW version and a hardware backboard are compatible.

The prior technical scheme has the following problems: during board production, the dial switch is set to a default state, which represents a default configuration. And the board card enters a to-be-shipped state after being produced and put in storage. If the goods are delivered with the requirement change, a production line operator needs to manually dial the dial switch to the configuration dial of the goods delivery requirement. In the actual operation process, it is found that a production line operator is not familiar with dial operation, different dials are not clearly distributed to different configurations, and dial errors often occur, so that the outgoing board card cannot support the required configuration.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following explains key terms appearing in the present invention.

The BMC executes a server remote Management controller, which is called Basebard Management controller in English. The method can perform operations such as firmware upgrading, machine equipment checking and the like 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 as well as RAM for data storage, flash memory and firmware for non-volatile data storage, providing basic remote manageability in terms of secure remote restart, secure re-power-up, LAN alerts and system health monitoring. In addition to the basic IPMI function and system operation monitoring function, the mBMC enables selection and protection of BIOS flash devices by storing the previous BIOS using one of 2 flash memories. For example, when the system cannot be started after the remote BIOS is upgraded, the remote administrator can switch back to the BIOS image that worked before to start the system. Once BIOS is upgraded, BIOS image can be locked to prevent virus from invading it.

The I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus to transfer data and to generate a clock to open up the devices that are transferring, when any addressed device is considered a slave device. If the host wants to send data to the slave device, the host addresses the slave device first, then actively sends the data to the slave device, and finally the host terminates the data transmission; the master device addresses the slave device first if the master device is to receive data from the slave device. 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 a programmable logic device with high density, high speed and low power consumption.

An Intelligent Platform Management Interface (IPMI for short) can span different operating systems, firmware and hardware platforms, and can intelligently monitor, control and automatically report the operating conditions of a large number of servers, so as to reduce the system cost of the servers.

The Flash storage area available for the UFM user is a non-volatile memory, and data stored after power failure cannot be lost.

FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a default configuration update system for a hard disk backplane.

As shown in fig. 1, the method includes:

step 110, constructing a communication link between the complex programmable logic device and the substrate management controller, wherein the complex programmable logic device receives and stores dial-up information sent by the substrate management controller through the communication link;

step 120, searching for target configuration data corresponding to the dial-up information according to a locally stored configuration list, where the configuration list includes configuration data corresponding to a plurality of dial-up information;

and step 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 update method of the default configuration of the hard disk backplane provided by the present invention is further described below with reference to the principle of the update method of the default configuration of the hard disk backplane of the present invention and the process of updating the default configuration of the hard disk backplane in the embodiment.

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

and S1, constructing a communication link between the complex programmable logic device and the substrate management controller, and receiving and storing dial-up information sent by the substrate management controller through the communication link by the complex programmable logic device.

Connecting the complex programmable logic device with a baseboard management controller by using an I2C bus; and the encryption program of the complex programmable logic device sends verification information to the substrate management controller, wherein the verification information is used for verifying the identity of the information source, and the verified information has the authority of writing in the register. And the complex programmable logic device synchronously backs up dial information written into a register by the baseboard management controller to a nonvolatile memory area available to a user, and the dial information covers historical dial 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 dial-up information into a register of the complex programmable logic device by using an I2C instruction. This replaces the manual action of manual dialing. And simultaneously, the complicated programmable logic device synchronously backs up dial information written into a register by the substrate management controller to a nonvolatile memory area (UFM) available to a user, so that the dial information loss caused by power failure is avoided. The dial information covers historical dial information in the nonvolatile memory area available to the user, and the dial information in the nonvolatile memory area available to the user can be guaranteed to be always the latest. Meanwhile, the embodiment adds the function of identity verification to the complex programmable logic device, so that misoperation can be avoided, and only dial information with verification information is accepted.

S2, searching target configuration data corresponding to the dial-up information according to a locally stored configuration list, wherein the configuration list comprises configuration data corresponding to a plurality of types of dial-up information.

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

When planning the backboard, the different configurations to be adapted by 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 example of uplink configuration with different dial-up configurations

Dial configuration	Uplink configuration list
		0000 (Default)	Configuration 1 (Default)
0001	Configuration 2
		0010	Configuration 3
0011	Configuration 4
		…	…

The configuration list is stored in a nonvolatile memory area available to a user in the embodiment, so that the complex programmable logic device can be conveniently used while data is not lost. The CPLD writes default configuration (such as 0000) into the UFM in a burning mode when a board card is punched for the first time; the CPLD comprises two registers, when the CPLD is powered on for the first time to use dial information, the information is firstly read from the UFM and stored in the register 2 for use. The default state of the CPLD internal register 1 is set to be default configuration (0000), and in the operation process of the CPLD, when the BMC rewrites the dial information of the register 1 to be 0001 through a communication instruction, the CPLD writes 0001 into the register 2, and uses the uplink information of the register numerical value analysis configuration 2 (the configuration 2 corresponds to the dial 0001); and meanwhile, the CPLD synchronizes the register dial-up information 0001 to the UFM for storage. Under the condition of no power failure, the CPLD can directly read dial information from the register 2, and if the CPLD fails to read the dial information from the register in the process of operating the CPLD, the dial information needs to be read from the UFM, and the read dial information is synchronized to the register 2.

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

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

In another embodiment of the present invention, referring to fig. 2, the present embodiment provides a method for updating a default configuration of a hard disk backplane, including the following steps:

s1, BMC sets customer requirements and IPMI dialing instructions corresponding to the multiple dialing information in advance and arranges the multiple dialing information and the customer requirements corresponding to the multiple dialing information into a requirement list.

On this basis, the embodiment proposes a preferred embodiment, that is, the BMC outputs and displays the requirement list through a BMC WEB page, and the client requirement includes a plurality of requirement keywords.

By corresponding various dial-up information with the client requirements, a production line operator searches a target requirement keyword in a BMC WEB page, or inputs the requirement keyword, and the BMC can automatically search the corresponding dial-up information. The mode is convenient to operate, and the requirements on the working experience of production line operators are reduced.

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

The BMC writes the dial information selected by the user into a register of the complex programmable logic device through an I2C bus, and replaces the existing method of generating the dial information to the complex programmable logic device through a dial switch. Compared with a dial switch, the method based on the BMC provided by the embodiment has higher automation degree, and does not need to increase the space of a hardware hard disk backboard.

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

1. in the initial stage of project planning, the planning of lists with different dial codes and different uplink configurations is completed;

2. firstly burning default configuration of dial codes into a CPLD UFM register through a CPLD FW;

3. in the I2C link between the BMC and the CPLD, a command is added: the BMC can write the dial configuration required at present into the 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 the backboard is in other configurations when the backboard is assembled in a production line, a production line operator can issue a command under the system according to an operation instruction provided by a BMC engineer, the currently required configuration information 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 register value to complete the dial information resetting; and meanwhile, the CPLD synchronously stores the information written into the register by the BMC into the internal UFM, so that the power failure information of the CPLD is not lost.

Above solution has eliminated the manual action of producing the manual dial-up of line operator, has reduced the error rate when equipment machine, has improved the work efficiency when producing the line equipment simultaneously.
