Disk data read/write control method, related component, and front-end shared card

A method of controlling a read or write operation for disk data, applied to a front-end shared card, wherein a first end of the front-end shared card is connected with a host through M links, a second end of the front-end shared card is connected with a disk through N disk controllers, the front-end shared card and each of the disk controllers are connected through a built-in socket, and M and N are integers greater than 1, the front-end shared card establish the communication connection with the host through one or more links of the M links;

• and the method comprises:
• receiving a read or write task request of the host;
• determining a target disk controller from the N disk controllers based on the read or write task request;
• and
• controlling, based on the read or write task request, the target disk controller to perform a read or write operation on the disk;
• wherein the receiving a read or write task request of the host comprises:
• establishing instruction queues corresponding to the disk controllers on a one-to-one basis;
• and receiving the read or write task request of the host;
• the controlling, based on the read or write task request, the target disk controller to perform a read or write operation on the disk comprises:
• converting the read or write task request into a read or write operation instruction;
• and writing the read or write operation instruction into an instruction queue corresponding to the target disk controller, to cause the target disk controller to read the read or write operation instruction in the instruction queue and perform the read or write operation on the disk.
