Abstract: A control system of a disk array including multiple data storage disks is provided. The control system includes a front-end circuit, a central processing unit and a back-end circuit. The front-end circuit is for receiving multiple packets corresponding to a first protocol from a network. The central processing unit has multiple cores. One of the cores is configured as a first dedicated core to interpret the packets corresponding to the first protocol into multiple first commands. The other non-dedicated cores are for processing the first commands and outputting multiple first access instructions. The back-end circuit is for translating the first access instructions to access the data storage disks.
