Referring to FIG. 1 , it is a schematic structural diagram of an electronic device provided by an embodiment of the present invention. As shown in FIG. 1 , the electronic device may include a baseboard management controller 1 , multiple RAID cards, and multiple physical hard disks. In an exemplary embodiment, a RAID card 21, a RAID card 22, a RAID card 23, and a RAID card 24 may be included, and the four RAID cards may be RAID cards of different manufacturers, for example, the RAID cards 21 and 24 may be LSIs The manufacturer's RAID card, RAID card 22 and RAID card 23 may be RAID cards of the PMC manufacturer. Moreover, each RAID card is also connected in communication with the corresponding multiple physical hard disks, so as to control the multiple physical hard disks to form a storage array.

In addition, the RAID card 21, the RAID card 22, the RAID card 23, and the RAID card 24 are all connected in communication with the baseboard management controller 1, and the baseboard management controller 1 can control each RAID card. The specific connection method is implemented in the present invention The example is not limited. For example, the baseboard management controller 1 may be connected to each RAID card through an I2C bus. This embodiment of the present invention will take the above-mentioned physical architecture as an example to describe in detail the process of the baseboard management control 1 controlling each RAID card. Of course, it should be noted that the method for controlling a disk array card provided in the embodiment of the present invention may also be applied to any other physical architecture, which is not limited in the embodiment of the present invention.

Referring to FIG. 2 , it is a schematic flowchart of a method for controlling a disk array card provided by an embodiment of the present invention. As shown in FIG. 2 , an embodiment of the present invention shows a process in which a baseboard management controller controls a disk array card:

Step S101: Read the data of the device address of the disk array card.

In the first implementation, the baseboard management controller can traverse the device addresses on all bus channels and read the data on the device addresses.

In the second implementation case, the device address of the disk array card may also include a type code and an addressing code. The type code may identify the device type, for example, a RAID card device may have a specific type code, or any one of a group of specific type codes, used to identify the device as a RAID card device. In addition, the addressing code can identify devices belonging to one device type, that is, devices of the same type can have different addressing codes to distinguish. In this way, the type code and the addressing code can together form the device address of a device. Referring to FIG. 3, it is a schematic flowchart of a data reading method provided by an embodiment of the present invention. As shown in FIG. 3, the method includes:

Step S201: Obtain the type code and addressing code of the disk array card, wherein the addressing code shown is obtained by combining the number of bits of the addressing code in order.

In an exemplary embodiment, a 4-bit type code and a 3-bit addressing code may be included. During specific implementation, since different devices have different type codes, the type code "0001" of the disk array card can be searched from a preset list. Further, since the addressing code includes 3 bits, all addressing codes can be arranged and combined, namely "000", "001", "010", "100", "011", "101", "110", " 111".

Step S202: Combine the type code and the addressing code into the device address.

The device address can be obtained by determining the type code and addressing code according to step S201. In the above-described exemplary embodiment, 8 device addresses, ie, "0001000", "0001001", "0001010", "0001100", "0001011", "0001101", "0001110", and "0001111", can be obtained. Of course, in specific implementation, multiple type codes and multiple combined addressing codes can be determined, and all device addresses can be arranged and combined in the above manner.

Of course, it should be noted that, during specific implementation, a list of device addresses may also be established in advance, or an address range of a device may be preset, and device addresses may be managed through the list and address range, which will not be repeated in this embodiment of the present invention.

Step S203: Read the data of the combined device address.

Step S102: Determine the type of the disk array card according to the read data.

In the first implementation case, the type of the disk array card can be determined according to whether valid data is read.

During specific implementation, valid data may be non-null data, and invalid data may be null, including NULL or NA. In an exemplary embodiment, when the read data is valid data, it can be determined that the type of the disk array card is the first type, corresponding to the disk array card of the LSI manufacturer; when the read data has invalid data, it can be determined that the disk array card is of the first type. Make sure that the type of the disk array card is the second type, which corresponds to the disk array card of the PMC manufacturer.

In the second implementation case, the type of the disk array card can be determined by matching the read data.

In an exemplary embodiment, the first manufacturer can correspond to the first reference data, and the second manufacturer can correspond to the second reference data. When the read data is consistent with the first reference data, it can be determined that the disk array card belongs to the first reference data. A type; when the read data is consistent with the second reference data, it can be determined that the disk array card belongs to the second type.

Step S103: Invoke an application program matching the type to monitor the disk array.

According to the type of the disk array card obtained in step S102, an application program matching the type of the disk array card is further invoked to monitor the corresponding disk array. In specific implementation, when it is determined that the type of the disk array card is the first type, since the first type has a corresponding relationship with the first manufacturer, the application program provided by the first manufacturer can be invoked to monitor the disk array; in an exemplary embodiment , when the disk array card is of the first type and the first type has a corresponding relationship with the LSI manufacturer, the storelib library can be loaded to initialize the disk array card and run the application provided by the LSI manufacturer for monitoring. Of course, when it is determined that the type of the disk array card is the second type, since the second type has a corresponding relationship with the second manufacturer, the application program provided by the second manufacturer can be invoked to monitor the disk array; in an exemplary embodiment, when The disk array card is of the second type. When the second type has a corresponding relationship with the PMC manufacturer, it can be monitored directly with the application program provided by the Ning PMC manufacturer.

In this embodiment of the present invention, in order to prevent the same application from being called multiple times, in an exemplary embodiment, it may be further determined whether an application matching the type exists in the process, and when it does not exist in the process, The application matching the type is invoked; when present in the process, the application matching the type is not invoked. In specific implementation, when it is judged that the type of the disk array card is the first type and there is an application program of the first type in the process, the application program corresponding to the first type is not called; when the type of the disk array card is the first type If there is no application program of the first type frequently, the application program corresponding to the first type is called.

It can be seen from the description of the above embodiments that in a method for controlling a disk array card provided by the embodiment of the present invention, the baseboard management controller reads the data of the device address of the disk array card; and determines the disk array according to the read data. The type of card; invokes the application matching the stated type to monitor the disk array. In this way, when there are many different types of disk array cards, the baseboard management controller can distinguish different disk array cards, and call different applications to monitor the disk array. In the case of mixed disk array cards, it can effectively improve the reliability.

From the description of the above method embodiments, those skilled in the art can clearly understand that the present invention can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is better implementation.
