Description
Technical field
The present invention relates to a kind of high speed solid storage hard disk of SATA interface, in 3.5 cun hard disk structures of standard, realize solid state hard disc array, realize data interconnect by SATA interface and main frame based on RAID.
Background technology
Redundant Array of Independent Disks is one of effective ways that solve Computer I/O bottleneck, and vast potential for future development is arranged.Spreading all over day by day of the develop rapidly of computing machine and correlation technique thereof and computer utility, more and more higher requirement has been proposed computer memory technical.Therefore, this capacity of disk array is big, reliability is high, respond rapidly memory technology is more and more paid attention to by people.
At present, the main memory device of disk array is a mechanical hard disk.Mechanical hard disk is owing to the restriction that is subject on the principle own, its readwrite performance particularly random read-write performance can not satisfy the needs of various application far away, and traditional mechanical hard disk poor reliability, power consumption are big, in the field such as industry, military affairs, space flight that with wide temperature, antivibration, economize on electricity is the high reliability of principal character, this storage medium has become the most difficult requirement even the insurmountable problem of reaching.
As the best way that overcomes the above problems, become a kind of trend of replacement mechanical hard disk as the solid state hard disc of storage and control carrier with semiconductor.
The SSD solid state hard disc be possess high-effect, the rapid memory body Storage Media element of high stability, for usefulness cost at present than the most excellent memory body Storage Media solution.Have the multinomial advantage that replaces conventional hard, adopt the control technology that meets the industrial standard interface.Electronic hard disc can provide original, high performance and highly reliable data storing, even work under harsh conditions-abominable temperature, bump, vibrations, interference etc., also can not constitute a threat to data.It has overcome the disadvantage of mechanical hard disk, can be widely used in the data field of high reliability such as Industry Control, public safety, telecommunications, military project, aviation, and advantage such as its volume is little, storage space is flexible, expense is low, also is widely used in civil area.Electronic hard disc is different from the mechanical type hard disk, frequently switching on and shutting down and not damaging.
With the solid state hard disc be storage medium the RAID system set the various advantages of solid state hard disc and the advantage of array management, can satisfy the highly reliable application demand of various high speeds.
Summary of the invention
Limited and cause the limited present situation of suitable application area at the existing machinery hard disk performance, propose to replace traditional mechanical hard disk with solid state hard disc RAID system, improve the I/O characteristic and the reliability of existing hard disk.The system integration SATARAID controller 2 and based on the high-speed high capacity SATA interface solid hard disk 1 of FLASH array, in the single-deck of normal structure, realize solid state hard disc RAID system, compact conformation, has improved the readwrite performance and the reliability of single hard disk greatly at wide temperature, antivibration, low-power consumption.
Technical scheme of the present invention is: adopt the SATA interface solid hard disk of being made up of NAND FLASH array, FLASH controller 4 and SATA interface protocol 61, in the standard hard drive structure, connect SATA RAID controller 2 and form the RAID system, conformance with standard SATA interface links to each other with main frame, realizes the solid-state RAID of high performance single-deck structure system.
The structure of the solid state hard disc 1 of SATA interface is: Nand Flash array 3 is connected with Flash controller 4, and Flash controller 4 connects MPU (microprocessor) 5, and MPU5 connects SATA interface protocol 6, and SATA interface protocol 6 connects SATA interface 7.
Flash controller 4 is realized hardware ECC (bug check and correction) verification and Flash bad block management, guarantees that data storage is lasting.Microprocessor 5 is realized the storage and the read functions of data by the read-write operation of Flash controller realization to the FLASH array.The mode of FLASH array management can significantly realize the expansion of capacity and speed, and maximum can reach the capacity of 512GB and the storage speed of 300MB/s.Hard disk adopts IP to realize SATA2.0 STD bus agreement, can realize the transmission speed of 3.0Gbps.
SATA RAID controller possesses a plurality of SATA interfaces, can connect the solid state hard disc of a plurality of SATA interfaces.SATA RAID controller adopts the SATA control chip, supports the carry of SATA II interface protocol hard disk, and the data rate of each port can reach 300MB/s.The RAID rank of RAID controller support is RAID0, RAID1 isotype, can the better protect storage card in the safety of data, and restore data automatically, easy to use, simplified operator's management greatly.
The present invention has following advantage:
1: select the SATA interface solid hard disk for use, when inheriting the versatility of mechanical hard disk, the excellent physical characteristics and the environmental characteristics that provide mechanical hard disk not have, and the field of storage of hard disk expanded to field such as civilian, industrial, military, space flight.
2: adopt NAND type FLASH as storage medium, have characteristics such as the power down data are not lost, long service life.
3: adopt the RAID technology, in 3.5 cun hard disk structures of standard, provide RAID function, expanded storage speed and reliability greatly, simultaneously can the better protect storage card in the safety of data.
4: the advantage of solid state hard disc and the above-mentioned architectural feature single-deck RAID system based on solid-state storage that makes has features such as high reliability, high-performance, low-power consumption, environment for use are extensive.
