Problems solved by technology

[0003] Generally speaking, the transmission interface of this type of storage device (for example, hard disk) mostly adopts Small Computer System Interface (Small Computer System Interface, SCSI). Under the consideration of small and medium-sized enterprises, it will not be able to afford such a high-cost storage area network system
[0004] Therefore, the hard disk of the serial ATA transmission interface is included in the design considerations. Although the current serial ATA transmission interface is slightly lower than the small computer system interface (SCSI) in terms of data transmission speed, its manufacturing cost can meet the needs of small and medium-sized enterprises. requirements, only the serial ATA transmission interface has a single-channel interface specification, so for the storage area network system, its transmission channel is obviously insufficient

Abstract

The invention discloses a control system and control card of the serial advanced technology attachment, which comprises: a first serial ATA control module, a first storage arbitrating unit, a second serial ATA control module, a second storage arbitrating unit, and a path choosing unit. It uses the first and second storage arbitrating unit to do arbitrating interpretative routine to decide the storage power and generates a choosing signal to the path choosing module by the interpretative result to switch the data transmitting path to the serial ATA control module with storage power.

Description

technical field [0001] The invention relates to a hard disk interface control system, in particular to a multi-channel Serial ATA (Serial ATA, SATA) control system applied to a storage area network (Storage Area Network, SAN) system. Background technique [0002] With the advent of the information age, many enterprises use the storage area network (SAN) system to solve the problem of important data management and storage, and the storage area network system is a network architecture composed of storage devices. System management, when the data is damaged, the storage area network system can provide relevant remedial measures to restore the data to the state before the damage, so as to improve the reliability and stability of the computer system (Reliability) and stability (Stability). [0003] Generally speaking, the transmission interface of this type of storage device (for example, hard disk) mostly adopts Small Computer System Interface (Small Computer System Interface, S...
