  • Method, device and system for storing data in cache in case of power failure
    Patent number: 8156376
    Abstract: A method, device and system for storing data in a cache in case of power failure are disclosed. The method includes: in case of power failure of a storage system, receiving configuration information from a central processing unit (CPU); establishing a mapping relationship between an address of data in the cache and an address in a storage device according to the configuration information; sending a signaling message that carries the mapping relationship to the cache, so that the cache migrates the data to the storage device according to the signaling message.

  • DATA TRANSFER METHOD AND SYSTEM
    Publication number: 20090025014
    Abstract: A data transfer method and an Internet Small Computer Systems Interface controller are disclosed. At least one mirror iSCSI controller is preset for each iSCSI controller. The mirror iSCSI controller detects failure of the mirrored iSCSI controller corresponding to the mirror iSCSI controller, and adds service information of the mirrored iSCSI controller to the mirror iSCSI controller. The mirror iSCSI controller receives a log-in request sent from an iSCSI host which originally has logged in the mirrored iSCSI controller. The mirror iSCSI controller conducts data transfer with the iSCSI host in accordance with the service information.
