Patent ID: 11100037

Abstract:
An extended storage device based on a PCIe bus is provided. The extended storage device includes: a video processing device and a RAID card. The video processing device is connected to the RAID card via a PCIe bus; and the RAID card is constructed by an embedded system on chip (SoC). The video processing device may be connected to the RAID card via the PCIe bus, and virtual hard disk nodes corresponding to respective physical hard disk nodes of the RAID card may be built at the video processing device, so that the video processing device may manage physical hard disk nodes of the RAID card as managing a local hard disk, and then may organize these virtual hard disk nodes into a virtual RAID node, while the complex RAID computing is actually achieved through the SOC of the RAID card without occupying resources of CPU of the video processing device, so that a normal operation of business of the video processing device can be ensured.
