The embedded type CPCI structure magnetic disc array card (27) has advantages of small room required by holding hard disks, high speed of reading data from or writing data on hard disks, and strong expandability.

Description

Embedded CPCI structure disk array card

Technical field

The utility model relates to a kind of novel disk array integrated circuit board, the disk array integrated circuit board that particularly a kind of built-in field is used.

Background technology

Along with the embedded functional module to miniaturization, intensification, intelligentized development, requirement to the data storage capacity is more and more higher, corresponding disk array integrated circuit board will possess the ability that can hold more disks under the finite volume environment, and will have the function of direct storage external data so that satisfy the special applications of built-in field.And the disk array that uses in built-in field at present all is to be the control core with CPU, the form of employing disk array cabinet realizes, it is big to take up room, the Installation and Debugging difficulty, the single in addition CPU of depending on reads and writes disk array, can greatly reduce CPU and handle the ability of other things, even under the big situation of CPU Processing tasks amount, can cause the reduction of its read-write disk array ability and can't realize the function of high-speed data recording; And existing disk array card can not be the special function of customization, poor expandability; For fields such as industry control and robotization, its requirement to processing capability in real time and extended capability is all very high, and existing disk array control product can not satisfy its needs.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of Embedded CPCI structure disk array card is provided, but this disk array card holds the little high speed reading writing harddisk of hard disk requisite space volume, extendability is strong.

The technical scheme that the utility model adopted is: a kind of Embedded CPCI structure disk array card, comprise disk array read-write control chip and hard disk fixed area, the SATA I interface control by standard is embedded in the hard disk on the CPCI disk array card as the FPGA of main control chip; Embedded CPCI structure disk array card evenly is divided into four zones that are used for placing embedded hard disk, its each zone have respectively four be used for fixing four corners of embedded hard disk and and the contour fixture of Embedded CPCI structure disk array card-edge support; An embedded pci bridge chip on the Embedded CPCI structure disk array card, being provided with one on the Embedded CPCI structure disk array card can be by the connector of the data on the host computer direct read CPCI disk array card, a directly connector of storage external data is set on the Embedded CPCI structure disk array card, a direct connector to the external transmission data is set on the Embedded CPCI structure disk array card.

The utility model adopts the read-write of FPGA as main control chip control disk array, has broken away from the shortcoming of single CPU control disk array read-write, thereby has improved the speed and the reliability of read-write disk array; Employing standard SATA I interface is higher by the serial transmission security; Mark off the layout that four zones are used for placing four embedded hard disks with adopting the CPCI compact conformation, promoted the capacity of veneer disk array, greatly reduce hard disk and take up space; And the connector of pci bridge chip, storage external data, to the setting of connector on Embedded CPCI structure disk array card of external transmission data, realized the expanded function that customizes.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in more detail.

As shown in Figure 1, on Embedded CPCI structure disk array card 27, evenly dividing four zones that are used for placing embedded hard disk, by with its RAID card edge support 22 contour 1,2,3,4 fixtures are placed first embedded hard disk, by with its RAID card edge support 22 contour 5,6,7,8 fixtures are placed second embedded hard disk, by with its RAID card edge support 22 contour 9,10,11,12 fixtures are placed the 3rd embedded hard disk, by with its RAID card edge support 22 contour 13,14,15,16 4 fixtures are placed the 4th embedded hard disk; FPGA main control chip 17 is read and write by 23 pairs of first embedded hard disks of standard SATA I interface, read and write by 24 pairs of second embedded hard disks of standard SATA I interface, read and write by 26 pairs of the 3rd embedded hard disks of standard SATA I interface, read and write by 25 pairs of the 4th embedded hard disks of standard SATA I interface; Have a slice pci bridge chip 18 on the Embedded CPCI structure disk array card 27, host computer can stick into row control and monitoring to entire plate by this chip, configuration CPCI disk array card by host computer can be by the data on the connector 19 direct read CPCI disk array cards, in addition, CPCI disk array card can be stored the external data that connector 20 sends, and also can directly send data to the outside through connector 21.This host computer data of can storing also can be stored the structure of external data belong to initiative in the disk array card, for built-in field should be used for saying very convenient.
