Abstract


Network-attached storage (Network Attached Storage) and Storage Area Network (Storage Area Network) is a network storage device using the current mainstream technology . NAS is based on Ethernet technology , the use of TCP / IP protocol suite , provides file-level data sharing capabilities ; SAN Fibre Channel technology is based on using the Fibre Channel protocol, providing block-level data sharing capabilities. In some internal needs airborne fiber-based file-level data sharing service , NAS and SAN are not well positioned to meet the needs of such equipment , response to this demand , design and implement a fiber-based file-level sharing system FC-NAS . Detailed analysis of the FC-2 Fibre Channel protocol layer data frame format and content designed Fibre Channel-based file-level data sharing scheme FC-NAS, FC-NAS gives detailed implementation processes and important functions . On this basis , given the FC-NAS to achieve a specific hardware collaboration solution , and use of existing hardware environment , the realization of the design. Simultaneously with the current Ethernet-based file-level data sharing transmission schemes were analyzed. FC-NAS hardware devices running the PC for the x86 architecture , the operating system is used in embedded real-time system VxWorks, for the target machine, the operating system to complete the corresponding content development . Fibre Channel adapters based on Xilinx ML505 development board developed hardware devices in VxWorks device drivers to complete the preparation of the hardware to enable Fibre Channel adapters normal frame-level data transceiver. FC-NAS upper achieve compliance with the NFS protocol , divided into client and server side, client-side and server-side upper file system commands and data related operations are encapsulated in frames , and the frame is passed to the lower fiber channel adapter driver , the use of complete Fibre Channel frame level data transceiver. FC-NAS running configuration, client server file mapping as a local file read and write I / O operations .
