Apply in the current computers, request of saving quantity becomes more and more greatly.For example, saving a great deal of picture documents in the database, saving several customers'various of data in the network served medium, having a great deal of voice and picture document in the video frequency manufacture etc, need 100 several GBs even some TBs of the disk saving capacity. SAN(Storage Area Network) in the district provide the big capacity the solution of saving equipments share. Storage Area network in the district is saving equipments independence at the host system outside, constitute a saving network to provide a different server usage.The SAN is a kind of high-speed network, provide at the calculator and save the data of of system to deliver.The saving equipments means one or more disk equipmentses in order to saved a calculator data.A SAN is composed of being responsibled for the correspondence structure of network conjunction and being responsibled for organizing copular management layer, saving parts and calculator system, thus assurance data deliver of safety and accuracy. VSAN(Virtual Storage Area Network) which is a kind of SAN net equipments from logical dividing the line into a district, carry out a virtual work thus of the newly arisen data of set hand over a technique with each other.The report text in the same VSAN's delivering only then can receive, but can't deliver to the members in VSAN to deliver to the other VSAN.The FC(Fiber Channel) protocol applies most extensive protocol in SAN net and VSAN net currently.The FC correspondence makes use of a fiber-optic alternant technique of the passage realization report text, its essence is a set of hardware(like fiber-optic and fiber-optic net card etc.) and several layer integrities that provides high speed to deliver function to deliver protocol of gather.The FC network is costly, the equipments investment and maintenance workloads are more big, expandsive bad, so it need to put FC net and existing Ethernet net together, among them, the FCoE(Fibre Channel over Ethernet) technique satisfy a network to unify with data and hands over with each other is a currently better technique, it means FCoE protocol to load FC protocol in applying the foundation of more extensive Ethernet network, SAN network and LAN the network unites as one and delivers to act for the original FC physical layer through FCM(Fibre Channel Mapping) and Ethernet network. The FCoE son module piece provided an order to go interface CLI(Command-line Inter face). The Command-line interface CLI is allowed customers and operate system to pass an order and can choose the talk point combines of an interface.It is an interface that provided manager and the persons who use system to operate FCoE Command-line Interface.First this article analyzed the technique characteristics of FC and FCoE protocol, the basic knowledge of the constituting of SAN net, VSAN net and Ethernet structure, prepares a function module for the FCoE order module designing and realization, then it discussed FCoE order module on the need of function analysis, design realization and test, this part is the point of this article. In the end, the article carries on summary and item to develop the insight in the process to realize to this item and analyzes in the meantime and solved some problem in the process of an item development, and also gave the author's some outlooks to this item. |
