System and method for controlling sas expander to electronically connect to a raid card

A non-transitory storage medium storing a set of instructions, when executed by at least one processor of an electronic device, cause the at least one processor to perform a method for controlling a serial attached small computer system interface (SAS) expander to electronically connect to a redundant array of independent disks (RAID) card, the method comprising:

• establishing a plurality of different types of RAID cards according to RAID levels that the RAID cards support, and establishing configuration parameters of the SAS expander corresponding to each type of the RAID cards in a storage system of the electronic device;
• reading information of the RAID card in the electronic device if the SAS expander is electronically connected to the RAID card, the read information comprising RAID levels that the RAID card supports;
• determining whether the RAID card matches the SAS expander;
• reading the configuration parameters of the SAS expander corresponding to the RAID card, and writing the read configuration parameters and the read information of the RAID card into a firmware file in the storage system, if the RAID card does not match the SAS expander;
• and
• storing the firmware file into a flash memory of the SAS expander.

An electronic device, comprising:

• a serial attached small computer system interface (SAS) expander,
• a redundant array of independent disks (RAID) card;
• a storage system;
• at least one processor;
• and
• one or more programs that are stored in the storage system and executed by the at least one processor, the one or more programs comprising:
• an establishment module that establishes a plurality of different types of RAID cards according to RAID levels that the RAID cards support, and establishes configuration parameters of the SAS expander corresponding to each type of the RAID cards in the storage system;
• a first reading module that reads information of the RAID card if the SAS expander is electronically connected to the RAID card, the read information comprising RAID levels that the RAID card supports;
• a determination module that determines whether the RAID card matches the SAS expander;
• a second reading module that reads the configuration parameters of the SAS expander corresponding to the RAID card, and writes the read configuration parameters and the read information of the RAID card into a firmware file in the storage system, if the RAID card does not match the SAS expander;
• a matching module that stores the firmware file into a flash memory of the SAS expander.
