Abstract
The on-board data storage resource Distributed sharing network system based on AFDX that the present invention relates to a kind of.On-board data storage resource Distributed sharing architecture design is proposed in conjunction with NVMe and AFDX.NVMe is the layer protocol in PCIe buses, towards be solid-state electronic disc apparatus, have many advantages, such as high bandwidth, low latency.AFDX is a kind of on-board data exchange network, has strong reliability.For the shortcomings of current stored on-board resource is disperseed, utilization rate is low, I O access path is tediously long, the present invention proposes AFDX being transplanted to one layer of bottom data communication network of formation on memory node, shorten I O access path, and access bandwidth is improved by ripe NVMe agreements.
Description
Technical field
AFDX is the common network-bus of aviation field, it promotes the rate of network-bus data transmission in avionics system
100/1000Mbps is arrived, PCIe buses are common high-speed serial bus.The method that this patent proposes combines two kinds of buses
The advantages of improve the speed of data transmission under airborne circumstance, reliability and to complete the full machine of on-board data shared.PCIe is total
Line runs gen 2.0, and agreement is the bottom bus data exchange network that NVMe. is formed by AFDX in storage system, is met airborne
The resource-sharing of distributed storage device provides better storage service for onboard client end equipment.
Background technology
Communication between aviation airborne equipment and data exchange are one of the critical components of entire airborne avionics system.With
The continuous development of aeronautical engineering, requirement of the airborne avionics system to data/address bus further increases, and needs advanced high speed total
Line supports high speed, real-time data transmission between each electronic equipment.On the other hand, the data of airborne equipment are currently in point
Cloth but not shared state, the storage resource between different system, distinct device can not carry out shared and low latency and quickly count
According to interaction.Therefore, a kind of generalization is developed, the sharable on-board data storage share framework of high efficiency answers the following aeronautical engineering
With being of great significance.For the data characteristic of aviation high reliability request and high bandwidth, AFDX is shared as the storage architecture
The selection of network.Traditional stored on-board interface largely uses SATA buses, and the SATAIII limit at present, does not have
The leeway that can further improve.PCIe is interconnection high speed bus between currently used equipment inner panel, and it also just become deposit later
The mainstream interface bus of product is stored up, there is high speed, the characteristic of low latency, I O access path is short, and conventional store product is compared in delay
Interface low 50%, on this basis, the proposition specification of the NVMe agreements storage product of PCIe interface.It is traditional at present airborne to set
Standby network is largely the backbone network based on fiber optic protocols, and all node devices are linked into backbone switch and carry out data exchange,
But the storage resource of each node device causes the storage resource of entire aircraft to disperse not share, Er Qiesuo by self-management
There is the interaction of data that the airborne equipment by front end is required for enter backbone network and carry out data interaction, I O access path is tediously long, money
Source utilization rate is poor.Based on current present situation, a kind of shared point of high bandwidth, low latency, storage resource suitable for aircraft is proposed
Cloth storage architecture designs.
Invention content
Goal of the invention
The present invention combination NVMe and AFDX propose on-board data storage resource Distributed sharing architecture design.NVMe is PCIe
A layer protocol in bus, towards be solid-state electronic disc apparatus, have many advantages, such as high bandwidth, low latency.AFDX is a kind of machine
Data switching networks is carried, there is strong reliability.For the dispersion of current stored on-board resource, utilization rate is low, I O access path is tediously long
The shortcomings of, AFDX is transplanted to one layer of bottom data communication network of formation on memory node by the proposition of this patent novelty, is shortened
I O access path, and access bandwidth is improved by ripe NVMe agreements.
Technical solution
The present invention provides a kind of on-board data storage resource Distributed sharing network system based on AFDX, including optical fiber is handed over
It changes planes, multiple client, multiple memories and AFDX interchangers；The AFDX interchangers have data communication interface, and
AFDX interchangers are connect by AFDX networks with multiple memories, and each memory passes through PCI-E with a corresponding client
Interface connects, and all clients are connect with optical fiber switch by FC-AE buses, and optical fiber switch connects with data communication
Mouthful.
For the present invention using AFDX network-bus as the data interaction bus between bottom memory bank, PCIe buses are passed through in inside
It is transferred on storage medium and carries out reading and writing data, optical fiber backbone network and underlying data network separation are realized, to reduce optical fiber
The bandwidth occupancy of core network.Client runs a set of data management configuration software, and the spontaneous number of data bottom is carried out according to configuration
According to read-write.After initiating a reading task such as client 1, inquiring required data storage specific location by configuration software, (example is deposited
Store up in body n), then during the data in memory bank n directly to be read to the caching of client 1 by AFDX interchanger bottom-layer networks into
Row, which calculates, to be used, and entire data-moving process needs not move through optical fiber switch.
