Problems solved by technology

[0004] Although the external IDE hard disk drive, SCSI hard disk drive, CD-ROM drive or the above-mentioned serial ATA hard disk drive all use standard power supplies, the above-mentioned various transmission interfaces cannot transmit enough power to the external storage device through the adapter card of the computer motherboard. system 20, so the computer 10 cannot directly use its internal power supply to provide the power required by the external storage system 20; in other words, the external storage system 20 must provide the required power with an additional external power supply 21, so the overall The construction cost will increase relatively

[0022] image 3 Representing the block diagram of the switching device of the first embodiment of the present invention, image 3 The adapter device 33 in is an example of an expansion slot installed in a computer. Such as image 3 As shown, the adapter device 33 of the first embodiment is a PCI-to-Serial ATA interface card, which is installed in the PCI slot 35 of the motherboard 38, and includes a PCI interface circuit 331, a PCI-to-Serial ATA control logic circuit 332 and integration connector 333 . The PCI interface circuit 331 is used to receive hard disk-like access commands, such as hard disk read / write / control commands, sent from the motherboard 38 through the PCI slot 35 . The PCI-to-Serial ATA control logic circuit 332 is coupled to the PCI interface circuit 331 to receive the first type of hard disk access command, and convert the first type of hard disk access command into a second type of hard disk access command conforming to the serial ATA interface. Hard di...

Abstract

The changeover arrangement includes an interface circuit, a control logic circuit and an accordant connector. The interface circuit is utilized to receive commands in first category from computer for accessing hard disk. The control logic circuit is coupled to the interface circuit for receiving commands in first category and converting the commands in first category to commands in second category for accessing hard disk. The accordant connector coupled to the control logic circuit as well as to computer power supplier is utilized to deliver electric power provided by commands in second category and power supplier to external storage system, making computer provide power for external storage system as well as execute accessing action at same time.

Description

technical field [0001] The invention relates to a switching device, in particular to a switching device suitable for a computer system, which simultaneously supplies power and access functions to an external storage system through an integrated connector. Background technique [0002] Serial ATA interface (Serinl ATA, S-ATA) is a new data transfer interface, compared with traditional parallel ATA interface (Parallel ATA, P-ATA), serial ATA interface has low transmission power requirements, pin Less, high noise immunity, long effective distance and hot-swappable, so it is very suitable as a transmission interface for external storage systems. [0003] figure 1 It is a system architecture diagram of an external storage system in the prior art. Such as figure 1 As shown, it includes an adapter device 12 connected to a computer 10 (or server host) through an interface circuit 11, and an external storage system 20 connected to the adapter device 12 through an external cable 13...
