Specifically, by presetting different path selection algorithms, the path corresponding to the HBA card with the best hardware performance can be selected for data transmission; or, the paths can be allocated in proportion for data transmission.

Further, as shown in FIG. 4 , the present invention shows a schematic flowchart of acquiring hardware configuration information, step S300 may include:
