Abstract
The invention discloses a network data monitoring device for an optical fiber channel. The network data monitoring device comprises a magnetic disc array system of a multi-core CPU (central processing unit), and a piece of PCIe (peripheral component interface express) data interface card which is connected with the magnetic disc array system, thereby an FC (fiber channel) optical fiber channel interface is formed so as to form a high-speed data channel from a PCIe bus to the magnetic disc array. With the adoption of the device, a large capacity DDR (double data rate) memory is prevented from being used in the FC data interface card, and the magnetic disc array comprising ordinary sata2 hard discs is adopted, so that the continuous storage time under highest input data velocity (2Gb/s) is larger than 3 hours. The device has the beneficial effects that both the application requirements on long-time high-speed monitoring and storage to an FC network port are met, the realization cost is reduced, and no large-capacity DDR memories or high-speed electronic hard discs are needed.
Description
Technical field
The invention belongs to network data monitoring technique field, relate in particular to a kind of fiber channel network data monitoring device.
Background technology
Military aviation electronic system (abbreviation avionics) is " brain " of opportunity of combat, and it has carried most tasks such as communication/navigation/identification (CNI), electronic warfare of decision opportunity of combat performance.Along with the raising and the development of electronic technology of opportunity of combat mission requirements, all exist various transmission requirements between each inside, functional areas of airborne electronic equipment system and the functional areas, to bandwidth and transmission delay require increasingly high.
Along with going deep into of synthesization, adopt unified optical interconnection network to become the inexorable trend of avionics system interconnected.Fiber channel protocol is that the subordinate's of the American National Standard agreement committee (ANSI) X3T11 work group formulates a kind of host-host protocol with high speed serialization ability, has high reliability, high bandwidth, characteristics that real-time is high.In numerous candidate's standards, fiber channel protocol is shown one's talent, and becomes the interconnect standard of opportunity of combat avionics system of future generation.
The function of optical-fibre channel data monitoring system is that the carrying out that the FC onboard networks is carried out data shown in real time and store, and the data of storage is carried out instant analysis handle.Monitor terminal not only can receive the FC data that the FC switch sends, can also be directly and another FC network terminal interconnect.The optical-fibre channel FC protocol analysis system of present commercialization; Product like external FINISAR company, AM company; Can only partly satisfy optical-fibre channel data monitoring demand, only support the monitoring and the analysis of (the high-speed burst data in several approximately seconds) in short-term, owing to need plate to carry big capacity dynamic memory; Cost is very high, therefore a kind of practical cheaply FC network data supervisory control system of necessary research and development.
Summary of the invention
Technical problem to be solved by this invention is: the most application tasks of aviation electronics to the source purpose between the connection request high bandwidth (＞Gb/s), the transmission characteristic of high burstiness, low delay (us magnitude); For the ruuning situation of various application tasks is monitored in real time and is analyzed; Study its performance and investigation fault; Need a kind of carrying out that the FC onboard networks is carried out data of design to show in real time and high speed storing, and the data of storage are carried out the supervisory control system that instant analysis is handled.
The present invention realizes like this; A kind of fiber channel network data monitoring device; Said network data supervising device comprises the disc array system of a multi-core CPU; With a PCIe data interface card that is attached thereto, constitute a FC fiber channel interface through the high-speed data channel of PCIe bus to disk array.
Further, Intel multinuclear mainboard or 1 Intel multinuclear mainboard of said 1 FC data-interface card module, 1 band disk array interface add disk array card, a SATA2 disk array.
Further; Said employing PCI Express4X interface is as the communication interface of FC data interface card and Intel multinuclear mainboard, and the FC network data gets into data interface card through optical fiber, process string and conversion, buffer memory on the FC data interface card; Send into computer through PCI Express bus; Computer is imported data through application identification, and according to user's needs, selects corresponding data to store disk array into through RAID card.
Further, start DMA transmission and high efficiency pipelining automatically, accomplish the FC fiber channel interface to the choke free data forwarding of the high-speed data channel of disk array through hardware control in the FC data interface card.
Further, the disk array that adopts the Sata2 hard disk to form, can the highest input data rate (2Gb/s) following continuous memory time greater than 3 hours.
The invention has the beneficial effects as follows, can satisfy, reduced the realization cost again, do not need expensive big capacity DDR memory or high-velocity electrons hard disk the long-time high speed monitoring of the FC network port and the application demand of storage.
