Problems solved by technology

This high-speed serial interface copy machine can only operate independently. If one of the SATA or SAS disk drives needs to be directly connected to the computer for data transmission with the computer, the current system cannot achieve this function. Therefore, it cannot provide the user's needs for versatility

Abstract

The invention provides a data transmission device for a high-speed sequence transmission interface and a control method thereof. The device comprises a control unit, at least one first storage device connected with the control unit, at least one second storage device and at least one commutator for switching data transmission circuits; each commutator is connected with the control unit, the second storage device and a computer; the device and the computer can carry out data transmission through the commutator, or the device can be switched to a data transmission control device which can independently operate so as to carry out data transmission between storage devices; and the connection between the device and the computer is controlled or the data transmission device is independently operated through an automatic detection mode and a manual mode.

Description

technical field [0001] The present invention relates to a data transmission device and a control method, in particular to a data duplication or backup device and a method for controlling its data transmission connection. Background technique [0002] With the generation and circulation of a large amount of data in the information age, there are more and more demands for data backup and duplication, such as mass burning and duplication of CDs, storage and backup of computer and network data, hard disk system restoration, and multiple disk drives. The data duplication etc. between can be handled by duplicator or backup control system. Duplicators currently on the market are composed of a controller and a plurality of hard disk drives or optical drives, and the data is copied or burned between the hard drives or optical drives through the controller. [0003] With the development of high-speed serial transmission interface technology, Serial SCSI (SAS, Serial Attached SCSI) co...
