Obviously, the drawings in the following description are only the embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained according to the provided drawings without creative efforts.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In this application, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including a..." does not exclude the presence of additional identical elements in the process, method, article or device including the element.

[0034] As can be seen from the background art, a large-capacity storage device (Bulk Storage) may involve a situation where multiple expander chips are used in the same disk array system, and each Expander chip needs to load the corresponding firmware Bin file and configuration parameter Bin file. The foregoing situation will cause the firmware Bin files and configuration parameter Bin files of multiple Expander chips to appear in a disk array (Just a Bunch of Disk, JBOD) system, which will increase the maintenance difficulty of the firmware of the Expander chip, and further increase the operation risk of the disk array system.

[0035] Therefore, the embodiments of the present invention provide a method, device and disk array system for processing a configuration file of an expander chip, which pre-write the configuration files corresponding to each backplane identifier into a normalized firmware, and the backplane identifier corresponds to an expander backplane. When the disk array system is powered on, the level signal of a specified pin on the target expander backplane corresponding to the target expander chip is read, and the target backplane identifier is determined according to the level signal of the specified pin. The configuration file corresponding to the target backplane identifier is read from the normalized firmware corresponding to the target expander chip. By writing the configuration files corresponding to multiple expander backplanes into the normalized firmware, the normalization of the configuration files is realized, thereby reducing the maintenance difficulty of the firmware of the expander chip and reducing the operation risk of the disk array system.

[0036] It should be noted that through research, the inventor has found that currently, general servers are all equipped with an expander to achieve connection of more hard drives for the purpose of capacity expansion. However, the existing expander has at most 76 ports, which cannot meet the requirements of ultra-large-capacity storage devices. A bulk storage device will involve the situation of using multiple expanders in the same disk array system, that is, one expander serves as an I / O board, and multiple other expanders serve as BP (Backplane) boards for connecting hard drives. However, in the case of using multiple expanders as described above, each expander needs to load the corresponding firmware Bin file and configuration parameter Bin file due to different hardware configurations; this means that there will be multiple different firmware Bin files and configuration parameter Bin files under the same disk array system. After distributing multiple different firmware Bin files and configuration parameter Bin files under the same disk array system to relevant departments (such as R & D department, testing department, production department, operation and maintenance department, etc.), it brings great inconvenience to the maintenance of the firmware, and at the same time, there will be a situation of upgrading mismatched firmware, thus increasing the operation risk of the disk array system. Therefore, this solution realizes the normalization of the configuration file by writing the configuration files corresponding to multiple expander backplanes into the normalized firmware, thereby reducing the firmware maintenance difficulty of the expander chip and reducing the operation risk of the disk array system. The following will explain this solution in detail through various embodiments.

[0037] Furthermore, it should be noted that this solution is applicable to the target expander chip, which is any expander chip in the disk array system; that is to say, any expander chip in the disk array system can adopt this solution to read the corresponding configuration file.

[0038] See Figure 1 , which shows a flowchart of a method for processing a configuration file of an expander chip provided by an embodiment of the present invention. This method is applicable to the target expander chip, which is any expander chip in the disk array system. The method includes:

[0039] Step S101: When the disk array system is powered on, read the level signal of a specified pin on the target expander backplane corresponding to the target expander chip.

[0040] It should be noted that the target expander chip is connected to the specified pins on the corresponding target expander backplane, or rather, there are multiple specified pins on the target expander backplane connected to multiple specified pins of the target expander chip.

[0041] Since the level signals are divided into high level (usually represented by the number 1) and low level (usually represented by the number 0), the level signals of the designated pins can be used to determine the backplane identification of the target expander backplane (that is, the expander backplanes can be distinguished), and the number of designated pins can be determined according to the number of expander chips in the disk array system. The number of designated pins needs to meet the following prerequisite: the backplane identification (represented by Board ID) obtained by combining the level signals of each designated pin needs to be able to distinguish the expander backplanes corresponding to all expander chips in the disk array system. The expander backplanes corresponding to different expander chips correspond to different backplane identifications.

[0042] In some embodiments, the designated pins can be general-purpose input / output pins (GPIO PINs), or other types of pins, and the type of the designated pins is not limited herein.

[0043] In the process of specifically implementing step S101, when the disk array system is powered on and working, the target expander chip reads the level signals of the designated pins on the target expander backplane corresponding to the target expander chip.

[0044] Step S102: Determine the target backplane identification corresponding to the target expander backplane according to the level signals of the designated pins.

[0045] It should be noted that the preset sorting order of each designated pin is determined in advance.

[0046] In the process of specifically implementing step S102, the target expander chip sorts and combines the level signals of each designated pin according to the preset sorting order of each designated pin to determine the target backplane identification corresponding to the target expander backplane.

[0047] For example: Suppose the designated pins are GPIO65 and GPIO66, and the preset sorting order is GPIO65, GPIO66; the target expander chip reads the level signal of GPIO65 on the target expander backplane as 1, and reads the level signal of GPIO66 as 0; combined according to the aforementioned preset sorting order, the obtained target backplane identification is "10".

[0048] Step S103: Read the configuration file corresponding to the target backplane identification from the normalized firmware corresponding to the target expander chip.

[0049] It should be noted that, as can be seen from the content in step S101 above, according to the preset sorting order of each designated pin, different level signals of each designated pin can be combined to obtain multiple backplane identifiers for differentiating the expander backplanes in the disk array system; that is, different level signals of each designated pin are combined to obtain multiple backplane identifiers, and each backplane identifier corresponds to the expander backplane corresponding to a certain expander chip in the disk array system.

[0050] In some embodiments, data form conversion processing is performed on the configuration files of the expander backplanes corresponding to each expander chip in the disk array system in advance; a corresponding relationship is established between the backplane identifier corresponding to the expander backplane and the processed (data form conversion processed) configuration file, and then the processed configuration file is written into the normalized firmware.

[0051] That is to say, the normalized firmware stores the configuration files corresponding to multiple pre-written backplane identifiers, and the backplane identifiers correspond to the expander backplanes corresponding to the expander chips in the disk array system. The firmware (Expander Firmware) corresponding to each expander chip in the disk array system is all this normalized firmware (the normalized firmware is usually placed in the Flash of the Expander).

[0052] It can be understood that the file format of the configuration file of the expander backplane is Comma-Separated Values (CSV), and the data form in the CSV format configuration file is in the form of a table. To facilitate the subsequent reading of the configuration file, the data form in the configuration file can be converted into an array form.

[0053] Specifically, the specific method of the above-mentioned data form conversion processing is: using a preset development tool, converting the data in the configuration file from the form of a table into an array form, and writing the configuration file (which needs to establish a corresponding relationship with the backplane identifier) into the normalized firmware.

[0054] In some embodiments, the data form in the configuration file in the normalized firmware is in the form of an array. Through the above method, the data of the configuration files of each expander backplane in the disk array system can be compiled into the normalized firmware in the form of an array.

[0055] It can be understood that the data form in the configuration file in the normalized firmware is in the form of an array. To facilitate the reading of the configuration file, a reading function is constructed in advance using a Software Development Kit (SDK). This reading function can read CSV files and can read the corresponding configuration file using the backplane identifier.

[0056] In the process of specifically implementing step S103, the target expander chip calls a preset reading function to read configuration data in a configuration file corresponding to the target backplane identifier from the normalized firmware corresponding to the target expander chip. Specifically, the reading function is executed to read the configuration data (in the form of an array) in the corresponding configuration file according to the target backplane identifier.

[0057] In some embodiments, after the target expander chip reads the configuration file corresponding to the target backplane identifier, the target expander chip is configured based on the read configuration file corresponding to the target backplane identifier; specifically, the target expander chip configures the corresponding Expander based on the read configuration file corresponding to the target backplane identifier.

[0058] It should be noted that each expander chip in the disk array system can adopt the content in the above steps S101 to S103 to read the configuration file corresponding to the corresponding expander backplane. That is, the backplane identifier for distinguishing the expander backplane is obtained through the level signal of the specified pin on the expander backplane, and then the configuration file corresponding to the backplane identifier is read from the normalized firmware, so as to achieve the purpose of normalizing the Expander Firmware under the same disk array system.

[0059] In the embodiment of the present invention, the configuration files corresponding to each backplane identifier are pre-written into the normalized firmware, and the backplane identifier corresponds to the expander backplane. When the disk array system is powered on, the level signal of the specified pin on the target expander backplane corresponding to the target expander chip is read, and the target backplane identifier is determined according to the level signal of the specified pin. The configuration file corresponding to the target backplane identifier is read from the normalized firmware corresponding to the target expander chip. By writing the configuration files corresponding to multiple expander backplanes into the normalized firmware to achieve the normalization of the configuration files, the firmware maintenance difficulty of the expander chip is reduced and the operation risk of the disk array system is reduced.

[0060] To better explain the processing method of the configuration file of the expander chip provided in the above embodiment of the present invention, it is Figure 2 illustrated by an example.

[0061] See Figure 2 , Figure 2 which is a schematic diagram of the architecture of the disk array system provided in the embodiment of the present invention; Figure 2Among them, the disk array system includes 3 expanders (supporting a total of 118 drives). One of the expander backplanes serves as an IO board to be responsible for connecting to the Host Bus Adapter (HBA), and the other 2 expanders serve as BP boards to be responsible for connecting the 118 drives on the hard disk backplane. Among them, the expander chip corresponding to the IO board is denoted as the IO chip (corresponding to the Figure 2 IO Expander in it), and the expander chips corresponding to the 2 BP boards are respectively denoted as the BP0 chip (corresponding to the Figure 2 BP0 Expander in it) and the BP1 chip (corresponding to the Figure 2 BP1 Expander in it).

[0062] 60 drives are configured to be connected on the BP0 Expander, and 58 drives are configured to be connected on the BP1 Expander. There are 2 specific pins on the 3 expander backplanes, and these 2 specific pins are respectively connected to the GPIO65 pin and the GPIO66 pin of the IO chip, the BP0 chip, and the BP1 chip. The GPIO65 pin and the GPIO66 pin are the designated pins. The backplane identifiers corresponding to each expander backplane are shown in Table 1.

[0063] Table 1:

[0064] GPIO65 GPIO66 Backplane Identification IO 0 0 00 BP0 0 1 01 BP1 1 0 10

[0065] Taking the BP0 chip as the target expander chip as an example, the process of reading the configuration file is illustrated as follows: When the disk array system is powered on, the BP0 chip reads the level signals of the GPIO65 pin and the GPIO66 pin of the expander backplane of BP0. Among them, the level signal of the GPIO65 pin is 0, and the level signal of the GPIO66 pin is 1. The BP0 chip determines that the target backplane identifier is "01". The BP0 chip reads the configuration file corresponding to "01" from the normalized firmware.

[0066] Regarding the ways for the IO chip and the BP1 chip to read the configuration file, refer to the above content, and it will not be elaborated here.

[0067] Through the above Figure 2 content, it can be seen that since the disk array system includes 3 expanders, it is sufficient to distinguish the expander backplanes through the two designated pins of the GPIO65 pin and the GPIO66 pin. In practical applications, the number of designated pins needs to be determined according to the number of expander chips (or the number of expanders) of the disk array system.

[0068] As Figure 3 shown in another schematic diagram of the architecture of the provided disk array system, Figure 3The mid-disk array system contains 5 expanders (supporting a total of 108 drives). One of the expander backplanes serves as an IO board to be responsible for connecting to the HBA, and the other 4 expanders serve as BP boards to be responsible for connecting the 108 drives on the hard disk backplane. The expander chip corresponding to the IO board is denoted as the IO chip (corresponding to the Figure 3 IO Expander therein), and the expander chips corresponding to the 4 BP boards are respectively denoted as the BP0 chip (corresponding to the Figure 3 BP0 Expander therein), the BPl chip (corresponding to the Figure 3 BPl Expander therein), the BP2 chip (corresponding to the Figure 3 BP2 Expander therein), and the BP3 chip (corresponding to the Figure 3 BP3 Expander therein).

[0069] Since Figure 3 the disk array system contains 5 expanders, at least 3 designated pins are required to distinguish each expander backplane.

[0070] There are 3 specific pins on the 5 expander backplanes, and these 3 specific pins are respectively connected to the GPIO1 pin, GPIO2 pin, and GPIO3 pin of the IO chip, BP0 chip, BP1 chip, BP2 chip, and BP3 chip. The GPIO1 pin, GPIO2 pin, and GPIO3 pin are the designated pins. The determination method of the backplane identifier corresponding to each expander backplane can refer to Table 1 above, and no examples will be given here.

[0071] Through the above Figure 2 and Figure 3 it can be seen that all Expander hardware designs need to have unified designated pins (not limited to GPIO PINs), so that backplane identifiers can be generated, and then different expander backplanes can be distinguished through the backplane identifiers.

[0072] To further explain the content of each step in the above embodiments of the present invention Figure 1 the following examples are given through processes A1 to A7.

[0073] A1. Since the configuration file in CSV format contains the most primitive basic configuration information, the configuration files of each expander backplane can be modified respectively according to the differences of the expander backplanes (equivalent to different hard disk configurations actually mounted on different expanders).

[0074] A2. Since the data form in the configuration file (after modification) is in the form of a table, the data form in the configuration file is first converted into an array form by using a preset development tool.

[0075] A3. Compile the configuration file of the expander backplane processed by processes A1 and A2 into the normalized firmware.

[0076] A4. Use the SDK to build a reading function and compile it to generate the normalized firmware. This reading function can read CSV files and can read the corresponding configuration file using the backplane identifier.

[0077] A5. When the disk array system is powered on, the target expander chip reads the level signal of the specified pin on the target expander backplane corresponding to the target expander chip.

[0078] A6. The target expander chip determines the target backplane identifier corresponding to the target expander backplane based on the read level signal.

[0079] A7. The target expander chip uses the reading function to read the configuration file corresponding to the target backplane identifier from the normalized firmware corresponding to the target expander chip.

[0080] The above is an example description of this solution; through this solution, it is convenient for R & D personnel, operation and maintenance personnel, etc. to maintain the version of the normalized firmware, improving the operation and maintenance efficiency; and it can also effectively avoid the problem of fault tolerance in the upgrade of the normalized firmware, thereby improving the security and reliability of the disk array system. Each expander backplane only needs to reserve a unified specified pin to achieve the distinction of expander backplanes (specifically distinguished by the backplane identifier), with the characteristics of low cost and high reliability.

[0084] In a specific implementation, the determination unit 402 is specifically configured to: sort and combine the level signals of each specified pin according to the preset sorting order of each specified pin to determine the target backplane identifier corresponding to the target expander backplane.

[0085] A second reading unit 403, configured to read a configuration file corresponding to a target backplane identifier from a normalized firmware corresponding to a target expander chip, where the normalized firmware stores configuration files corresponding to a plurality of pre-written backplane identifiers, and the backplane identifiers correspond to expander backplanes corresponding to expander chips in a disk array system.

[0086] In a specific implementation, the second reading unit 403 is specifically configured to: call a preset reading function to read a configuration file corresponding to a target backplane identifier from a normalized firmware corresponding to a target expander chip.

[0087] In some embodiments, the data form in the configuration file is an array form.

[0088] In an embodiment of the present invention, configuration files corresponding to respective backplane identifiers are pre-written into a normalized firmware, and the backplane identifiers correspond to expander backplanes. When the disk array system is powered on, a level signal of a specified pin on a target expander backplane corresponding to a target expander chip is read, and a target backplane identifier is determined according to the level signal of the specified pin. A configuration file corresponding to the target backplane identifier is read from a normalized firmware corresponding to the target expander chip. By writing configuration files corresponding to multiple expander backplanes into the normalized firmware, normalization of the configuration files is achieved, thereby reducing the firmware maintenance difficulty of the expander chip and reducing the operation risk of the disk array system.
