[0002] In the existing storage server operation and maintenance system, the BMC (Boredom Management Control) system usually adopts a dual flash (non-volatile memory) storage mode, that is, a one-master and one-backup design. Although this design can provide system redundancy, the backup flash is idle during normal operation.

[0003] In the dual flash solution currently commonly used in the industry, the resource utilization rate of the backup flash is extremely low. When the main flash is running stably, the storage space of the backup flash is completely unused, resulting in a waste of resources.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0033] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] First, some terms involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0035] ‌The BMC (Baseboard Management Controller) system is a dedicated controller used to monitor and manage servers. It is independent of the server's operating system and hardware and provides an access interface through the IPMI (Intelligent Platform Management Interface) protocol. ‌‌

[0036] Flash (non-volatile memory) space is a non-volatile memory used to store data and programs. It uses electronic methods to read and write, with fast access speed and high reliability.

[0037] The present application is applied to the scenario of storage server application. The specific scenario is to store the data of the BMC system in different areas of the storage server by dividing the storage server, so as to ensure that different flashes in the BMC system can realize the operation of the BMC system and the reasonable storage of resources.

[0038] However, in the existing storage server operation and maintenance system, the BMC (management control) system usually adopts a dual flash (non-volatile memory) storage mode, that is, a one-master and one-backup design. Although this design can provide system redundancy, the backup flash is idle during normal operation. In the dual flash solution currently used in the industry, the resource utilization rate of the backup flash is extremely low. When the main flash is running stably, the storage space of the backup flash is completely unused, resulting in a waste of resources.

[0039] To this end, the present application divides the storage area of ​​the management controller BMC system, wherein the storage area includes a synchronization area and a shared area; through the synchronization area of ​​the storage area, the core function data of the main non-volatile memory and the backup non-volatile memory are synchronized, wherein the BMC system simultaneously mounts two storage chips of the main non-volatile memory and the backup non-volatile memory, and the core function data includes the operation data of the core function of the BMC system; through the shared area of ​​the storage area, the application data and operation data of the main non-volatile memory and the backup non-volatile memory are shared, wherein the application data and operation data are multiple applications in the BMC system and the operation data corresponding to multiple applications. By dividing the storage area of ​​the BMC system, the core function data of the two non-volatile memories can be synchronized, and the application data and operation data can be shared in the shared area. Through the hardware design of the storage chip and the above-mentioned area division method, the security of the shared area data can be guaranteed, and the corresponding data can be reasonably stored in different areas, so as to alleviate the phenomenon of resource waste in the process of sharing the dual non-volatile memories of the BMC system.

[0040] In the embodiment of the present application, the execution subject may be a BMC system dual non-volatile memory sharing device in a BMC system dual non-volatile memory sharing system. In actual applications, the BMC system dual non-volatile memory sharing device may be an electronic device such as a terminal device and a server, which is not limited here.

[0041] Combine the following Figure 1 The method for sharing dual non-volatile memories of a BMC system according to an embodiment of the present application is described in detail.

[0042] Please see Figure 1 , Figure 1 A flowchart of a method for sharing dual non-volatile memories in a BMC system provided by an embodiment of the present application is shown in FIG. Figure 1 The method for sharing dual non-volatile memories of a BMC system includes: Step 110: Divide the storage area of ​​the BMC system.

[0043] The storage area includes a synchronization area and a shared area. The BMC system simultaneously mounts two storage chips for the main non-volatile memory and the backup non-volatile memory. The BMC system chip supports two SPI (serial peripheral) interfaces to ensure that the two storage chips can be powered on and mounted in the system at the same time. The BMC system uses two SPI buses at the same time to ensure that the two storage chips are powered on at the same time, and the two storage chip areas can be seen under the BMC system. During the use of the system, the software is relied on to distinguish and call different flash areas.

[0044] In some embodiments of the present application, the main non-volatile memory includes a first boot area and a first shared area; the backup non-volatile memory includes a second boot area and a second shared area; the shared area includes a first shared area and a second shared area; and the synchronization area includes a first boot area and a second boot area.

[0045] In the above embodiment of the present application, by dividing the above area of ​​the main non-volatile memory, the functional program data and application program data when the BMC is started can be reasonably stored.

[0046] Optionally, the first startup area and the second startup area can constitute a first-level synchronization area, which can be used to start the BMC system. A storage area can also be separately divided as a second-level synchronization area to store some setting programs and program running data of the BMC system. The specific setting program can be set according to requirements.

[0047] Among them, the first-level synchronization area is the BMC system main and backup flash (main non-volatile memory and backup non-volatile memory) startup area. This area does not support modification and is the initial program area for the main and backup flash startup. The second-level synchronization area stores all key function programs and data to ensure that even if one flash is damaged, there is still a complete backup on the other flash to ensure that the core functions of the system are not lost; the startup area of ​​the main and backup flash is separated to ensure that when one flash is damaged, the system can still start normally and run the core functions. The design of the synchronization area ensures the security of key data. Even if one flash is damaged, there is still a complete backup on the other flash.

[0048] Optionally, BMC system space usage can be set by Figure 2 The specific principle schematic diagram shown is described in detail.

[0049] Please see Figure 2 , Figure 2 A schematic diagram of a BMC system space usage principle provided for this application, as shown in the figure, includes: BMC system and internal dual falsh space (main non-volatile memory flash0 and backup non-volatile memory flash1).

[0050] flash0 includes a first boot area, a first synchronization area and a shared area.

[0051] Flash1 includes a second boot area, a second synchronization area and the shared area.

[0052] Among them, both flashes have fixed and identical read-only areas, which are the BMC system startup area and data synchronization area. When the currently running BMC system is abnormal, the BMC system is started from the backup flash without affecting each other, and the newly started BMC reads the data in the BMC data synchronization area, synchronizes part of the status data of the last abnormal BMC or synchronizes the data in the main flash synchronization area, so that some BMC services can continue to run. The first startup area and the second startup area store the Bootloader (startup loader), BMC kernel and root file system.

[0053] The BMC system running program shared area is two flash running program shared areas, which are all areas except the startup area and data synchronization area; this area is actually two partitions, for example, 0 and 1. When the program is running, you can choose to save the data in area 0 or area 1. No matter which of the two areas, some commonly used application data, cache data, or log data can be stored. If the data is lost, it will not affect the re-collection of related data.

[0054] also, Figure 2 The specific BMC system space usage principle shown can be Figure 1 The specific methods and steps shown are implemented and will not be described in detail here.

[0055] Step 120: Synchronize the core function data of the main non-volatile memory and the backup non-volatile memory through the synchronization area of ​​the storage area.

[0056] Among them, the BMC system simultaneously mounts two storage chips of the main non-volatile memory and the backup non-volatile memory. The core function data of the main non-volatile memory and the backup non-volatile memory are the core function data stored in the main non-volatile memory and the backup non-volatile memory, including the operation data of the core function of the BMC system. The core function can be determined according to the BMC system with different functions.

[0057] In some embodiments of the present application, core functional data of a main non-volatile memory and a backup non-volatile memory are synchronized through a synchronization area of ​​a storage area, including: when the main non-volatile memory is damaged, synchronizing the core functional data in a first boot area of ​​the main non-volatile memory to a second boot area of ​​the backup non-volatile memory.

[0058] In the above process, the present application can ensure that the BMC system can be normally started and the main core functions can be enabled when the main non-volatile memory is damaged through synchronization of the core function data.

[0059] Among them, the core function data in the first boot area of ​​the main non-volatile memory can be synchronized to the second boot area of ​​the backup non-volatile memory by directly copying it to the second boot area of ​​the backup non-volatile memory in a copy and backup manner, or the core function data can be backed up to the cloud and the core function data stored in the cloud can be downloaded and stored in the second boot area of ​​the backup non-volatile memory.

[0060] In some embodiments of the present application, the core function data of the main non-volatile memory and the backup non-volatile memory are synchronized through the synchronization area of ​​the storage area, including: synchronizing the core function data stored in the synchronization area when the BMC system was last started to the main non-volatile memory and the backup non-volatile memory of the current BMC system.

[0061] In the above process, the present application can also synchronize the core function data used when the BMC system was last started to the main non-volatile memory and the backup non-volatile memory of the current BMC system, so as to quickly obtain the BMC core function data and start related functions.

[0062] The synchronization may be performed in the form of copy backup.

[0063] Step 130: Share the application data and operation data of the main non-volatile memory and the backup non-volatile memory through the shared area of ​​the storage area.

[0064] The application data and the operation data are multiple application programs in the BMC system and the operation data corresponding to the multiple application programs.

[0065] In some embodiments of the present application, application data and running data of a main non-volatile memory and a backup non-volatile memory are shared through a shared area of ​​a storage area, including: when the main non-volatile memory is damaged, sharing the application data and running data of the main non-volatile memory to a second shared area of ​​the backup non-volatile memory.

[0066] In the above process, the present application can ensure that the BMC system can operate normally and start the main application program when the main non-volatile memory is damaged by sharing the application program data and the operation data.

[0067] The second shared area and the first shared area may be combined into one shared area, and when the main non-volatile memory stores application data and running data, they may be stored in the shared area.

[0068] In some embodiments of the present application, after sharing the application data and running data of the main non-volatile memory and the backup non-volatile memory through the shared area of ​​the storage area, it also includes: when the main non-volatile memory is damaged, starting the BMC system through the backup non-volatile memory, and sharing the application data and running data to the backup non-volatile memory; detecting whether the main non-volatile memory can be recognized; when the main non-volatile memory can be recognized, detecting and initializing the first startup area of ​​the main non-volatile memory, and detecting whether the shared area is readable; when the main non-volatile memory cannot be recognized, issuing a damage warning of the main non-volatile memory.

[0069] In the above process, when the main non-volatile memory is damaged, the present application can also start the BMC system through the startup area of ​​the backup non-volatile memory through synchronized and shared data to prevent the BMC system from failing to start. When the main non-volatile memory cannot be identified, an early warning will be issued in time to achieve the effect of timely maintenance.

[0070] Among them, the early warning process includes information such as damage time and location.

[0071] In some embodiments of the present application, after sharing the application data and running data of the main non-volatile memory and the backup non-volatile memory through the shared area of ​​the storage area, it also includes: when the shared area of ​​the main non-volatile memory is full, storing the remaining application data and running data in the end area of ​​the shared area of ​​the backup non-volatile memory.

[0072] In the above process, the present application can store redundant data of the main non-volatile memory to the end area of ​​the shared area of ​​the backup non-volatile memory, thereby ensuring normal storage of subsequent data of the backup non-volatile memory and achieving the effect of reasonable use of storage space.

[0073] Among them, the BMC system includes multiple applications and corresponding application data. Multiple applications and corresponding application data can be stored in the shared area of ​​the main non-volatile memory first. When the shared area of ​​the main non-volatile memory is full, it is stored in the shared area of ​​the backup non-volatile memory. At the same time, larger logs are fixedly stored in the end area of ​​the shared area of ​​the backup non-volatile memory to ensure the real-time storage of large files; this is used to store applications and data, which significantly improves the utilization rate of storage resources.

[0074] In the above Figure 1 In the process shown, the present application divides the storage area of ​​the management controller BMC system, wherein the storage area includes a synchronization area and a shared area; through the synchronization area of ​​the storage area, the core function data of the main non-volatile memory and the backup non-volatile memory are synchronized, wherein the BMC system simultaneously mounts two storage chips of the main non-volatile memory and the backup non-volatile memory, and the core function data includes the operation data of the core function of the BMC system; through the shared area of ​​the storage area, the application data and operation data of the main non-volatile memory and the backup non-volatile memory are shared, wherein the application data and operation data are multiple applications in the BMC system and the operation data corresponding to multiple applications. By dividing the storage area of ​​the BMC system, the core function data of the two non-volatile memories can be synchronized, and the application data and operation data can be shared in the shared area. Through the hardware design of the storage chip and the above-mentioned area division method, the security of the shared area data can be guaranteed, and the corresponding data can be reasonably stored in different areas, so as to alleviate the phenomenon of resource waste in the process of sharing the dual non-volatile memories of the BMC system.

[0075] Combine the following Figure 3 The implementation method of the BMC system dual non-volatile memory sharing in the embodiment of the present application is described in detail.

[0076] Please see Figure 3 , Figure 3 A flowchart of an implementation method for sharing dual non-volatile memories in a BMC system provided in an embodiment of the present application is shown in FIG. Figure 3 The implementation method of the dual non-volatile memory sharing of the BMC system shown includes: The BMC system includes two falsh spaces (main non-volatile memory flash0 and backup non-volatile memory flash1).

[0077] When flash0 is damaged, BMC starts from flash1 and detects whether flash0 can be recognized. If not, it means that the flash0 chip is damaged and flash0 cannot be loaded. The loading of some programs in flash0 is skipped and BMC is started normally.

[0078] If flash0 can be identified, it means that the flash0 indication boot area of ​​BMC is damaged. Load flash0 to boot and initialize BMC flash0. When BMC boot is completed and the application runs normally, check whether the data in the flash0 shared area is readable and writable.

[0079] When the data in the flash0 shared area can be read and written normally, the BMC system operates normally, and an alarm is given that the BMCflash0 boot area is damaged. Please repair it.

[0080] When the data in the flash0 shared area cannot be read or written normally, uninstall flash0.
