Problems solved by technology

However, according to the IDE / ATA standard, the IDE / ATA interface is an interface with 40 signal lines and adopts parallel (parallel) transmission, and its longest transmission distance is only 18 inches, so when multiple IDE / ATA hard drives are used as When using disk array equipment, it is inevitable to encounter the problem of too short connection distance and too many signal lines, which lead to difficult or even impossible wiring.

Embodiment Construction

[0033] figure 1 It is a block diagram of a network storage device according to the present invention. As shown in the figure, the network storage device 10 includes a disk array controller 110, a disk array device composed of a plurality of disk devices 150a-150d, and a related interface converter 140. The disk devices 150a-150d are IDE / ATA hard drives, and each IDE / ATA hard drive 150a-150d provides a set of IDE / ATA interface signals 142a-142d. The disk array control device 100 includes a disk array controller 110 , an interface converter 120 and a network interface unit 130 . Besides, there is a micro-controller (micro-controller) 160 to control the disk array controller 110 , the interface converter 120 and the network interface unit 130 through control signals 162 - 166 . The microcontroller 160 reads the firmware programs and data stored in the non-volatile memory 170 via a shared bus 116 to perform the work of data flow control and storage management, and the microcontro...

Abstract

Magnet disc matrix controller used for network recording unit consists of a magnetic disc controlling unit, an interface converter and a network interface. The said disc controlling unit has a parallel interface to provide several groups of parallel signals and a common bus interface to receive or to transmit recorded data. The interface converter receives each group of parallel signals and convert them into correspondant differential signals when the disc matrix controller transmits data out. The interface converter does the contray operation when the disc matrix controller receives data.

Description

technical field [0001] The invention relates to a disk array control device, especially a disk array control device suitable for network storage devices. Background technique [0002] Due to the rapid growth of the network and the consequent huge data traffic, using safe, reliable and efficient network storage devices has become a trend in the information technology (Information Technology, IT) industry. Such network storage devices, such as Network Attached Storage (NAS), Storage Area Network (SAN), or Redundant Arrays of Independent Disks (RAID) servers, generally use disks with Disk array (disk array) device with fault tolerance (disk fault tolerance) function. A hard disk drive (for convenience, hereinafter referred to as IDE / ATA hard drive) with an integrated drive electronics (Integrated Drive Electronics, hereinafter referred to as IDE) (or AT Attachment, hereinafter referred to as ATA) interface, due to its cost Lower advantage, so it is often used to form a disk a...
