Description

Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a method, device, equipment and medium for performance tuning and configuration of a disk array card. Background Art

[0002] RAID (Redundant Array of Independent Disks) combines multiple physical hard disks into a single virtual large-capacity hard disk in some way, thereby providing higher storage performance, higher I / O (Input / Output) performance and reliability than a single hard disk. The main function of the RAID controller is to manage multiple hard disk drives and implement RAID-level data storage and data protection functions.

[0003] RAID cards are usually inserted into the expansion slot of a computer and act as an independent hardware component to manage and control the disk drives connected to the computer. It provides hardware-level RAID configuration, monitoring, and management functions, allowing users to flexibly configure various RAID levels (such as RAID 0, RAID 1, RAID 5, etc.) to meet their storage needs. The structure of a RAID card is relatively complex, consisting of a multi-core CPU (Central Processing Unit) and multiple IPs (IntellectualProperty), which implements dedicated hardware IO data acceleration for RAID functions. The firmware of a RAID card is a software program running in the RAID card, which is responsible for controlling and managing the IP, and also provides data segmentation, redundancy, read-write, backup, and recovery functions at different levels such as RAID 0 / 1 / 5 / 6.

[0004] During the computer startup process, you can enter the RAID card configuration interface through the BIOS (Basic Input Output System) settings or a dedicated RAID configuration tool, where you can choose to create RAID levels, stripe sizes, write policies, cache settings and other RAID parameters. This product form configuration is generally user-oriented and suitable for system testing and factory product configuration. However, the implementation of RAID cards is relatively complex, involving multiple systems and multiple IPs. It is difficult for users to maximize the performance of the RAID card's software and hardware synergy by setting it up based solely on their experience.

[0031] A parameter correction module is used to correct the current software and hardware quota based on the system performance indicator value to obtain the optimal software and hardware quota value of the input and output control unit under the target disk topology structure, and save the optimal software and hardware quota value to the configuration data file so that the optimal software and hardware quota value in the configuration data file can be loaded when each firmware system is running.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0048] RAID cards are usually inserted into the expansion slot of a computer as an independent hardware component to manage and control the disk drives connected to the computer. It provides hardware-level RAID configuration, monitoring and management functions, allowing users to flexibly configure various RAID levels (such as RAID 0, RAID 1, RAID 5, etc.) to meet their storage needs. The structure of the RAID card is relatively complex, consisting of a multi-core CPU and multiple IPs, and realizing dedicated hardware IO data acceleration for the RAID function. The firmware of the RAID card is a software program running in the RAID card, which is responsible for controlling and managing the IP, and also provides different levels of data segmentation, redundancy, read and write, backup and recovery functions such as RAID 0 / 1 / 5 / 6. During the computer startup process, enter the RAID card configuration interface through the BIOS settings or a special RAID configuration tool, and you can choose to create RAID parameters such as RAID level, stripe size, write strategy, cache settings, etc. This product form configuration is generally user-oriented and suitable for system testing and factory product configuration. However, the implementation of the RAID card is relatively complex, involving multiple systems and multiple IPs. It is difficult for users to maximize the performance of the software and hardware synergy of the RAID card by setting it only through their experience.

[0049] To this end, the embodiments of the present application disclose a method, apparatus, device and medium for performance tuning and configuration of a disk array card, which can perform performance tuning and configuration on the disk array card to give full play to the advantages of hardware acceleration and software acceleration and obtain the optimal performance of the disk array card.

[0050] See also Figure 1 As shown, the embodiment of the present application discloses a performance tuning configuration method for a disk array card, the method comprising:

[0051] Step S11: obtaining a pre-saved configuration data file from the firmware layer of the disk array card, and using the configuration data file to initialize the configuration of each firmware system in the disk array card.

[0052] In this embodiment, the firmware layer uniformly manages and saves the configuration data files, making the debugging of the software and hardware collaborative functions more convenient and reducing the debugging time and cost. In this solution, the configuration data files obtained from the firmware layer of the disk array card are first used to initialize the configuration of each firmware system in the disk array card.

[0053] It should be noted that a firmware configuration module for uniformly managing the configuration data files is provided in the firmware layer of the disk array card.

[0054] In a specific implementation, the configuration data file includes host interface parameters, acceleration unit parameters of the disk array card, and landing subsystem parameters; wherein the host interface parameters include the host interface mode, the number of physical functions, and the size of direct memory access; the acceleration unit parameters include the number of input and output control units, the working mode, the available memory size, and the input and output timeout; the landing subsystem parameters include the number of bus port extensions, the bus port extension mode, the root complex switch, the number of channels between the root complex and other bus devices, and the number of disks. That is, if Figure 2 As shown, the present application adds a firmware configuration module in the firmware layer, which is specifically responsible for the unified configuration of the host interface layer, the disk array card (RAID, Redundant Array of Independent Disks) acceleration unit and the disk drop system. It can be seen that the present invention defines RAID card configuration parameters according to the RAID card hierarchy, including host interface layer parameters, RAID acceleration unit parameters and disk drop system parameters, and performs performance tuning according to the parameter configuration.

[0055] Among them, the host interface layer is the PCIe (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) EP (Endpoint device, in EP mode, the PCIe controller receives read and write operations for local memory space) interface layer, which is responsible for NVMe (Non-Volatile Memory Express, non-volatile memory host controller interface specification) device enumeration and PCIe message queue management. The host interface parameters can be uniformly managed by the firmware configuration module, including the number of PF (Physical Function), host interface mode and DMA (Direct Memory Access) size. If the interface mode of the host interface layer is configured as software mode, the hardware acceleration unit will be skipped, and data processing will be packaged by the pure software module in the RAID acceleration unit. If the interface mode of the host interface layer is set to hybrid mode, the hardware acceleration unit will be used to package first. The software acceleration unit mainly handles operations that the hardware IP cannot handle, and the software and hardware work together to complete the package.

[0056] The RAID acceleration unit includes hardware IP and software modules, which are responsible for RAID management and IO (Input / Output) data processing. The firmware configuration module can uniformly manage the quota of software and hardware resources, including the number of input and output (IO) control units, performance / capacity working mode, available memory size, and input and output timeout. According to different product specifications, the firmware configuration module uniformly configures available resources to improve the ability of software and hardware to work together.

[0057] The disk placement system is the PCIe RC (root complex, in RC mode, the PCIe controller supports configuration and IO transactions) interface layer, which is responsible for disk management and disk reading and writing operations. The firmware configuration module can uniformly manage the number of PPMs (PCIe PortMultiplier, PCIe port extension), PPM mode (direct connection / Swich), RC switch, the number of channels between the root complex and other bus devices, and the number of disks (that is, the number of RC-lanes and the number of Namespaces), etc., so as to realize different disk topologies.

[0058] Furthermore, the firmware system includes a core control system for controlling bus devices and processing data, an auxiliary control system for system and interface communication, firmware upgrades, and system debugging control, a disk array card control system for user command processing and product form setting, a power management system for power supply, a power-off protection recovery system for system abnormal power-off data protection and system power-on data recovery, and a boot system for loading firmware system startup. It can be understood that the RAID card firmware is complex to implement and contains multiple firmware systems, including a core control system, an auxiliary control system, a RAID control system, a power management system, a power-off protection recovery system, and a boot system. Among them, the core control system is responsible for core control and data processing, including PCIe EP subsystem, RAID acceleration unit, and PCIe RC subsystem; the auxiliary control system is responsible for system and interface communication, firmware upgrades, and system debugging control; the RAID control system is responsible for user command processing, product form setting, etc.; the power management system is mainly responsible for power supply to each system of the RAID card; the power-off protection recovery system is responsible for system abnormal power-off data protection and system power-on data recovery; the boot system is responsible for loading other firmware systems, exiting after loading, and handing over control to the auxiliary control system.

[0059] Correspondingly, the method of obtaining a pre-saved configuration data file from the firmware layer of the disk array card to initialize and configure each firmware system in the disk array card using the configuration data file includes: loading the configuration data file pre-saved in the firmware configuration module into a preset global data area, so that each firmware system in the disk array card reads the configuration data file from the global data area through a corresponding interface to complete the local initialization configuration using the configuration data file. That is, the configuration data of multiple firmware systems are uniformly managed by the firmware configuration module, such as Figure 3As shown, first, the boot system loads the configuration data file into the preset global data area and provides a reading interface for the configuration data; then, during the system startup process, the core control system, auxiliary control system, and RAID control system read the configuration data in the configuration module to complete the system initialization process. It can be seen that this application proposes a RAID card configuration method for a heterogeneous multi-core system, in which the boot system uniformly loads the configuration data, and multiple systems including the core control system, auxiliary control system, RAID control system, power management system, power-off protection recovery system, etc. read the configuration data value through the shared global data area.

[0060] Step S12: If the parameter to be corrected is the software and hardware quota of the input and output control unit, then under the currently set target disk topology, the current software and hardware quota of the input and output control unit is set using the software and hardware quota value in the configuration data file, and the test case corresponding to the current software and hardware quota is executed to obtain the system performance indicator value.

[0061] In this embodiment, if the parameter to be corrected is the software and hardware quota of the input and output control unit, then under the currently set target disk topology, the current software and hardware quota of the input and output control unit is set using the software and hardware quota value in the configuration data file, and the test case corresponding to the current software and hardware quota is executed to obtain the system performance indicator value.

[0062] In another embodiment, if the parameter to be modified is a target function parameter that does not affect the startup process, the target function parameter is modified through a target serial port or a preset interface extension command during the operation of each firmware system.

[0063] It should be pointed out that, according to whether the parameters can be changed during the startup process, the RAID card configuration parameters can be divided into static parameters and dynamic parameters. Some static parameters are used for driver initialization during the system power-on process and are not allowed to be changed during system operation. However, their parameter values ​​are related to performance and need to be adjusted according to actual test results. The software and hardware quotas of the input and output control unit are static parameters. The static parameter correction methods are as follows: Figure 4 As shown in the figure, first, when the system starts, the configuration data file is loaded, and when the system is initialized, the driver and related modules are initialized according to the configuration data; secondly, the test cases are executed and the test results are counted; then, the parameter configuration values ​​are corrected according to the system performance indicators; finally, the optimal configuration values ​​in the configuration data file are determined according to the relationship between the parameter values ​​and the performance test data. Dynamic parameters mainly include functional parameters that do not affect the startup process, including debugging switches such as log and trace. During the operation of the system, they can be modified and take effect in real time through the serial port or NVMe extension command. Combined with the dynamic parameter configuration method of the debugging switch, it is convenient to locate and analyze functional problems and performance bottlenecks.

[0064] Step S13: Modify the current software and hardware quota based on the system performance indicator value to obtain the optimal software and hardware quota value of the input and output control unit under the target disk topology structure, and save the optimal software and hardware quota value to the configuration data file, so as to load the optimal software and hardware quota value in the configuration data file when each firmware system is running.

[0065] In this embodiment, after executing the test case corresponding to the current software and hardware quota and obtaining the system performance index value, the current software and hardware quota is corrected using the obtained system performance index value based on the relationship between the system performance index and the software and hardware quota, so as to obtain the optimal value of the software and hardware quota of the input and output control unit under the target disk topology. Finally, the optimal value of the software and hardware quota is saved in the configuration data file, so that these optimal configurations can be directly loaded when the system is running, thereby improving the system performance and stability. The above scheme can facilitate the functional debugging and performance tuning of the disk array card's software and hardware collaboration by uniformly managing the configuration data file at the firmware layer, giving full play to the advantages of hardware acceleration and software acceleration, and obtaining the optimal performance of the disk array card.

[0066] It can be seen that the present application obtains a pre-saved configuration data file from the firmware layer of the disk array card, and uses the configuration data file to initialize the configuration of each firmware system in the disk array card; if the parameter to be modified is the software and hardware quota of the input and output control unit, then under the currently set target disk topology structure, the current software and hardware quota of the input and output control unit is set using the software and hardware quota value in the configuration data file, and the test case corresponding to the current software and hardware quota is executed to obtain the system performance index value; based on the system performance index value, the current software and hardware quota is modified to obtain the optimal value of the software and hardware quota of the input and output control unit under the target disk topology structure, and the optimal value of the software and hardware quota is saved to the configuration data file, so that the optimal value of the software and hardware quota in the configuration data file is loaded when each of the firmware systems is running.

[0067] Beneficial effect: In this application, the firmware layer uniformly manages and saves configuration data files, making the functional debugging of software and hardware collaboration more convenient and reducing the debugging time and cost. In this scheme, the configuration data file obtained from the firmware layer of the disk array card is first used to initialize the configuration of each firmware system in the disk array card. Furthermore, if the parameter to be corrected is the software and hardware quota of the input and output control unit, the software and hardware quota value in the configuration data file is used to set the current software and hardware quota of the input and output control unit under the currently set target disk topology structure, and the test case corresponding to the current software and hardware quota is executed to obtain the system performance index value, and then based on the relationship between the system performance index and the software and hardware quota, the current software and hardware quota is corrected using the obtained system performance index value to obtain the optimal value of the software and hardware quota of the input and output control unit under the target disk topology structure. Finally, the optimal value of the software and hardware quota is saved in the configuration data file so that these optimal configurations can be directly loaded when the system is running to improve system performance and stability. The above solution can facilitate the function debugging and performance tuning of the disk array card hardware and software collaboration by uniformly managing the configuration data files at the firmware layer, give full play to the advantages of hardware acceleration and software acceleration, and obtain the optimal performance of the disk array card.

[0068] See also Figure 5 As shown, the embodiment of the present application discloses a specific disk array card performance tuning configuration method. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, it includes:

[0069] Step S21: obtaining a pre-saved configuration data file from the firmware layer of the disk array card, and using the configuration data file to initialize the configuration of each firmware system in the disk array card.

[0070] Step S22: If the parameter to be modified is the software and hardware quota of the input and output control unit, then under the currently set target disk topology, the first software and hardware quota value is taken out from the target array, and the current software and hardware quota of the input and output control unit is set using the first software and hardware quota value.

[0071] In this embodiment, it should be pointed out first that the software and hardware quota values ​​are multiple proportional values ​​obtained after pre-configuring the required resources between the software and hardware based on the number of available resources in the input and output control unit, and the software and hardware quota values ​​are stored in the target array pre-created in the firmware layer. That is, the application pre-configures the required resources between the software and hardware based on the number of available resources in the input and output control unit to obtain multiple proportional values, and stores them using an array. Therefore, when modifying the parameters, the first software and hardware quota value is first taken out from the target array, and the first software and hardware quota value is used to set the current software and hardware quota of the input and output control unit.

[0072] Step S23: executing a test case corresponding to the current software and hardware quota to obtain a first system performance indicator value.

[0073] In this embodiment, after the current software and hardware quota of the input and output control unit is set, a test case corresponding to the current software and hardware quota is executed to obtain a first system performance indicator value.

[0074] Step S24: traverse the target array to take out the next software and hardware quota value from the target array, and use the next software and hardware quota value to set the current software and hardware quota of the input and output control unit, and then execute the test case corresponding to the current software and hardware quota to obtain the second system performance indicator value.

[0075] In this embodiment, the target array is traversed continuously to take out the next software and hardware quota value from the target array, and the current software and hardware quota of the input and output control unit is set using the next software and hardware quota value, and then the test case corresponding to the current software and hardware quota is executed to obtain the second system performance index value. In a specific implementation, the present application can sequentially take out different software and hardware quota values ​​according to the storage order of the software and hardware quota values ​​in the array to set the current software and hardware quota of the input and output control unit, and then execute the corresponding test case to obtain the system performance index value; in another specific implementation, different software and hardware quota values ​​can also be taken out randomly or according to custom rules to set the current software and hardware quota of the input and output control unit, and this embodiment does not limit this.

[0076] Step S25: Determine whether there are any untraversed software and hardware quota values ​​in the target array. If so, jump back to the step of traversing the target array to retrieve the next software and hardware quota value from the target array until all software and hardware quota values ​​in the target array are traversed.

[0077] In this embodiment, it is determined whether there are any untraversed software and hardware quota values ​​in the target array. If so, the above steps are repeated until all software and hardware quota values ​​in the target array are traversed.

[0078] Step S26: Modify the current software and hardware quota based on the system performance indicator value to obtain the optimal software and hardware quota value of the input and output control unit under the target disk topology structure, and save the optimal software and hardware quota value to the configuration data file so that the optimal software and hardware quota value in the configuration data file can be loaded when each firmware system is running.

[0079] In this embodiment, all the system performance index values ​​obtained above are used to modify the current software and hardware quotas to obtain the optimal software and hardware quota values ​​of the input and output control unit under the target disk topology. Finally, the optimal software and hardware quota values ​​are saved in the configuration data file so that these optimal configurations can be directly loaded when the system is running to improve system performance and stability.

[0080] Furthermore, the above method also includes: determining the number of types of disk topology structures in the landing subsystem according to the configuration data file; accordingly, if the number is multiple, after obtaining the optimal value of the software and hardware quota of the input-output control unit under the target disk topology structure, it also includes: resetting the current disk topology structure, and using the new disk topology structure as the target disk topology structure, and then jumping to the step of setting the current software and hardware quota of the input-output control unit using the software and hardware quota values ​​in the configuration data file, so as to obtain the optimal value of the software and hardware quota of the input-output control unit under different disk topologies. It can be understood that, assuming that the landing subsystem has n types of disk topologies, one disk topology structure is set each time, and the above steps are repeated, so that the optimal values ​​of the software and hardware quota of the input-output control unit corresponding to the n types of disk topologies can be finally obtained.

[0081] For a more specific processing procedure of the above step S21, reference may be made to the corresponding contents disclosed in the above embodiments, which will not be described in detail here.

[0082] The following takes the parameter optimization process of the software and hardware available quota parameters of the IO data control unit in the RAID acceleration unit as an example to explain the above solution in detail. Figure 6 As shown:

[0083] The first step is to set the working mode of the RAID host interface to the hybrid working mode. In the hybrid working mode, the RAID control method in the RAID acceleration unit is mainly hardware acceleration, supplemented by software acceleration, and the software and hardware work together to complete the RAID acceleration function.

[0084] The second step is to determine the number of available resources of the IO data control unit in the RAID acceleration unit, and determine the software and hardware quota values ​​of the IO data control unit as (x0, x1, ..., xm).

[0085] The third step is to set the plate landing system parameters. A set of plate landing system parameters can be configured according to the plate topology.

[0086] The fourth step is to set the software and hardware quotas of the IO data control unit in the RAID acceleration unit.

[0087] Step 5: Execute the integration test related to the configuration item to obtain the performance indicator value. If the software and hardware quota values ​​(x0, x1, ..., xm) of the IO data control unit have not been traversed, repeat steps 4 and 5, modify the software and hardware quotas and execute the integration test case.

[0088] In the sixth step, based on the relationship between the performance index and the hardware and software quota of the IO data control unit, the optimal value of the hardware and software quota of the IO data control unit under a certain disk topology can be calculated and saved in the configuration data file. Assuming that the sub-system has n disk topologies (p1, p2, …, pn), each time a disk topology is set, and steps 3 to 6 are repeated, the optimal value of the hardware and software quota of the IO data control unit corresponding to the n disk topologies can be finally obtained.

[0089] It can be seen that this application proposes a performance tuning configuration method for a RAID card, which uniformly configures the available parameter values ​​of the hardware IP and software modules at the firmware layer, which not only facilitates the functional debugging and performance tuning of the RAID card's hardware and software collaboration, but also optimizes resource allocation and gives full play to the advantages of hardware acceleration and software acceleration, thereby obtaining the optimal performance of the RAID card.

[0090] See also Figure 7 As shown, the embodiment of the present application discloses a performance tuning configuration device for a disk array card, the device comprising:

[0091] The initialization configuration module 11 is used to obtain a pre-saved configuration data file from the firmware layer of the disk array card, so as to use the configuration data file to initialize the configuration of each firmware system in the disk array card;

[0092] The test module 12 is used for setting the current software and hardware quota of the input and output control unit by using the software and hardware quota value in the configuration data file under the currently set target disk topology structure if the parameter to be corrected is the software and hardware quota of the input and output control unit, and executing the test case corresponding to the current software and hardware quota to obtain the system performance indicator value;

[0093] The parameter correction module 13 is used to correct the current software and hardware quota based on the system performance indicator value to obtain the optimal software and hardware quota value of the input and output control unit under the target disk topology structure, and save the optimal software and hardware quota value to the configuration data file so that the optimal software and hardware quota value in the configuration data file can be loaded when each firmware system is running.

[0094] It can be seen that the present application obtains a pre-saved configuration data file from the firmware layer of the disk array card, and uses the configuration data file to initialize the configuration of each firmware system in the disk array card; if the parameter to be modified is the software and hardware quota of the input and output control unit, then under the currently set target disk topology structure, the current software and hardware quota of the input and output control unit is set using the software and hardware quota value in the configuration data file, and the test case corresponding to the current software and hardware quota is executed to obtain the system performance index value; based on the system performance index value, the current software and hardware quota is modified to obtain the optimal value of the software and hardware quota of the input and output control unit under the target disk topology structure, and the optimal value of the software and hardware quota is saved to the configuration data file, so that the optimal value of the software and hardware quota in the configuration data file is loaded when each of the firmware systems is running.

[0095] Beneficial effect: In this application, the firmware layer uniformly manages and saves configuration data files, making the functional debugging of software and hardware collaboration more convenient and reducing the debugging time and cost. In this scheme, the configuration data file obtained from the firmware layer of the disk array card is first used to initialize the configuration of each firmware system in the disk array card. Furthermore, if the parameter to be corrected is the software and hardware quota of the input and output control unit, the software and hardware quota value in the configuration data file is used to set the current software and hardware quota of the input and output control unit under the currently set target disk topology structure, and the test case corresponding to the current software and hardware quota is executed to obtain the system performance index value, and then based on the relationship between the system performance index and the software and hardware quota, the current software and hardware quota is corrected using the obtained system performance index value to obtain the optimal value of the software and hardware quota of the input and output control unit under the target disk topology structure. Finally, the optimal value of the software and hardware quota is saved in the configuration data file so that these optimal configurations can be directly loaded when the system is running to improve system performance and stability. The above solution can facilitate the function debugging and performance tuning of the disk array card hardware and software collaboration by uniformly managing the configuration data files at the firmware layer, give full play to the advantages of hardware acceleration and software acceleration, and obtain the optimal performance of the disk array card.
