Embodiment Construction
[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0051] The main idea of the present invention is: host channel interface driver module judges that if the destination equipment that receives the SCSI command that backup node server sends is Data Mover module, then send the message of receiving SCSI command to this Data Mover module, this Data Mover module will receive The SCSI command is sent to the SCSI command processing module;
[0052] The SCSI command processing module receives and analyzes the SCSI command, and after executing the parsed SCSI command, feeds back the execution result of the SCSI command to the Data Mover module; the Data Mover module receives the execution result of the SCSI command Afterwards, imitate the SCSI command format of the entity Data Mover device response system, and send the corresponding SCSI command response to the host channel interface driver module; th...
