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.
Claims22
A data transfer method, comprising:
- detecting, by a mirror iSCSI controller, failure of the mirrored iSCSI controller corresponding to the mirror iSCSI controller;
- adding service information of the mirrored iSCSI controller to the mirror iSCSI controller;
- receiving, by the mirror iSCSI controller, a log-in request sent from an iSCSI host, which originally has logged in the mirrored iSCSI controller;
- and
- processing the log-in request and transferring data with the iSCSI host according to the service information of the mirrored iSCSI controller.
A data transfer system, comprising:
- an iSCSI host adapted to re-send a log-in request when disconnection with a mirrored iSCSI controller that the iSCSI host logs in is detected;
- and
- a mirror iSCSI controller adapted to add service information of the mirrored iSCSI controller upon detection failure of the corresponding mirrored iSCSI controller, to receive the log-in request sent from the iSCSI host, and to conduct data transfer with the iSCSI host in accordance with the service information.
An iSCSI controller, comprising:
- a mirror failure processing module adapted to add service information of a corresponding mirrored iSCSI controller upon detection of failure of the mirrored iSCSI controller;
- and
- a data processing module adapted to conduct data transfer with an iSCSI host which originally has logged in the mirrored iSCSI controller.
A data transfer system, comprising:
- an iSCSI controller communicating with an iSCSI host, wherein the iSCSI controller is operable to:
- detect, failure of the mirrored iSCSI controller corresponding to the mirror iSCSI controller;
- add service information of the mirrored iSCSI controller to the mirror iSCSI controller;
- receive a log-in request sent from an iSCSI host which originally has logged in the mirrored iSCSI controller;
- and
- process the log-in request and transferring data with the iSCSI host according to the service information of the mirrored iSCSI controller.
