High-capacity SATA disk array was used in this system instead of tape library, and connects on-demand w ith the host w as implemented through the crossbar sw itch instead of manipulator. The storage system model w as proposed. The hardw are and firmware design of crossbar sw itch matrix , scheduling policy of the host, address-planning of system port, hardw are port and internal sw itch w ere respecti ely introduced. The prototype system show ed that the proposed system could meet the demand for massi e multimedia data storage.
