Description
Technical field
The present invention relates to dual control storage system field, specifically a kind of dual control storage system based on RapidIO.
Background technology
Storage device is the capital equipment of current data center, for storing the mass data in user or cloud computing,
It is required that with very high reliability, usually using RAID（English full name is Redundant Array of Independent
Disks, translator of Chinese is disk array）To improve the reliability of data, when one or several hard disks break down, change
Data can completely be recovered after hard disk, and this is the data backup scenario of single set system.But single RAID system is also simultaneously
Can not be completely secured the safety of data with it is reliable, thus it requires needing another set of standby system can when a system delays machine
It is operated with taking over main system in time, and data will not lose, the technology mainly applied at present is Double Control Skill.
Most popular data backup mode is carried out data transmission by Ethernet to dual control field of storage at present, ether
Net is the packet transmission mode of a kind of " doing one's best ", when network load is excessive, network delay can be caused excessive, causes number
According to loss, being generally basede on the system bandwidth of Ethernet will surpass with 20% to 70%.Therefore the equipment that Ethernet is best suitable for high time delay
Between apply, or on the relatively low plate of bandwidth requirement/plate between apply.
RapidIO interconnection architectures are an open standards, meet widespread need of the infrastructure in application aspect.Can
Capable application includes connection multiprocessor, memory, the memory mapping I/O devices on the network equipment, storage subsystem and led to
Use calculating platform.RapidIO is using three layers of staging hierarchy, and logical layer specification defines all accord and bag top
Form, they are that end points device is initiated and completion affairs are submitted necessary information；Transport layer specification is in intermediate layer, definition
RapidIO address spaces and required routing iinformation is transmitted between end points device；Physical layer specification is in whole hierarchical layer
Bottom, includes the details of device level interface, such as control of bag transmission mechanism, flow, electrical characteristic and lower level error management.
RapidIO technologies use high-performance LVDS technologies, and 10Gbps effective transmission speed can be realized in 4 pairs of differential lines, and
With the higher efficiency of transmission of ten thousand mbit ethernets, PCIE.
How RapidIO and Double Control Skill to be combined, improve the reliability and stability of storage system, be to need to solve
Technical problem.
The content of the invention
The technical assignment of the present invention is that deficiency is there is provided a kind of dual control storage system based on RapidIO for more than, to solve
The problem of certainly how improving the reliability and stability of storage system.
The technical assignment of the present invention is realized in the following manner：
A kind of dual control storage system based on RapidIO, each storage system includes RadioIO backup modules and by master control mould

SAS expansion modules, main control module and RapidIO data backup modules in array, each storage system pass through PCIE buses
It is sequentially connected, two RapidIO backup modules are connected by RapidIO buses.Pass through between two RAID disk arrays
RapidID backup modules form dual control storage system as the passage of data backup.
Further, main control module is the control system based on X86 structures.
Further, main control module includes system disk, VGA（English full name is Video Graphics Array, is IBM
A kind of video transmission standard released in 1987 with PS/2 machines, with high resolution, the fast, various colors of display speed etc.
Advantage, is widely used in color monitor field.Hot plug is supported, audio transmission is not supported.）Module, PCH（English
Literary full name is Platform Controller Hub, is the integrated south bridge of intel companies）Chip, processor, DDR（It is English complete
Referred to as Double Data Rate, translator of Chinese is dual-magnification technique synchronous DRAM）Chip and USB interface, system disk,
VGA modules and USB interface are connected with PCH chips, and PCH chips, processor and DDR chips are sequentially connected.
Further, SAS expansion modules include SAS expansion cards and multiple hard disks, and each hard disk connects with SAS expansion cards
Connect, SAS expansion cards are connected by PCIE buses with main control module.
A kind of dual control storage system based on RapidIO of the present invention has advantages below：Two storage systems pass through
RapidIO backup modules carry out data backup, constitute dual control storage system, and Ethernet and PCIE skills are replaced with RapidIO technologies
Art realizes the data backup between two RAID disk arrays, realizes efficient, the dual control storage system of high reliability, high stability.
