摘要： A method for improving an access efficiency of a small computer system interface (SCSI) storage device is used to process a plurality of access requests for a physical storage device from a request end. The task processing method includes setting a task queue in each virtual disk, for receiving a plurality of disk access tasks sent from a server; writing the disk access tasks to storage addresses in the virtual disk; executing a storage address recording, for recording the disk access tasks having the same storage address, and sending the rest disk access tasks in sequence to the physical storage device; saving the disk access tasks into a request queue of the physical storage device; executing a program sequence optimization on the disk access tasks in the request queue; and sending back the disk access tasks after the program optimization process to the virtual disk.
