DATA ARRANGING METHOD OF DISK ARRAY BY BLOCK DIVISION AND INPUT/OUTPUT CONTROL METHOD OF DISK ARRAY BY MULTI COMMAND MOORING TECHNIQUE

摘要

PURPOSE: A data arranging method of a disk array by block division and an input/output control method of the disk array by a multi command mooring technique are provided to divide high-capacity data according to the number of disks included in a disk array, and to distribute the divided data, so that all the disks can operate in parallel, thereby reducing an input time. CONSTITUTION: A system divides video/audio stream data into logical blocks according to input/output units of a file system(501). The system divides size of the logical blocks by the number of disks, and selects a certain value as a division unit(502). The system divides the logical blocks into split blocks(503). The system commands to sequentially arrange the split blocks on the disks of a disk array(504). If one logical block is processed, the system decides whether logical blocks remain(505). If not, the system completes the procedure.
