摘要*
随着信息技术的进一步发展,以及网络的大规模应用,带来了数据的爆炸性增长,
也给网络存储带来了巨大的发展机会。今天的存储系统己经形成了从简单的直连存储
到复杂的网络存储,从单个存储设备到多个存储设备的多层次、复杂的存储体系。
光纤通道 FC(Fibre Channel)结合了网络与通道的技术优势,具有低延迟、高带
宽和远距离传输的特性,是目前最为广泛应用的高速存储网络传输协议。
对象存储系统是一种新的网络存储体系结构,它结合了存储区域网的高性能和网
络附加存储的跨平台的优点。对象存储控制器是对象存储系统的关键部件之一。片上
可编程系统SOPC(System-on-Programmable-Chip)技术具备软硬件系统在线可编程的
功能,利用SOPC技术将光纤通道端口整合到对象存储控制器中,可有效缩短对象存
储控制器的I/O路径。
光纤通道端口在传输有效数据前,必须先成功登录到光纤通道网络中,取得动态
地址,协商通信参数。登录服务分为三类:架构登录,端口登录与进程登录,是光纤
通道协议的重要组成部分。原型系统中,硬件提供帧一级的收发接口,登录服务在
uCLinux(内核版本: )环境下用软件实现。测试结果表明,光纤通道端口能够
成功地登录到目的设备(qlogic 公司 QLA2310 型号光纤通道适配器)。

Abstract*
With the progress of information technology and the large scale application of ,
the amount of data have been substantial increased, it bring a large chance to the
development work storage contemporary. The storage system evolve from a direct
attached storage work storage and from with one disk into many of disks
multi-hierarchy plex system now.
Fibre bines the advantage work and channel, which provides low
latency, high bandwith and long-distance connection. It is the most widely used high-speed
work transmission protocol.
Object-based storage system is a work storage architecture, bines the
advantage of SAN’s high performance and NAS’s cross-platform data sharing.
Object-based storage controller is one of the ponents in Object-based storage
system. SOPC technology has the advantages for hardware and software customization
on-line. Designed with SOPC technology, fibre channel port is interfered into Object-based
storage controller, which could shorten the I/O path.
Before data transmission, fibre channel port must login work, obtain dynamic
address and munication parameters. There are three types of login serv
