摘　　要：在分析SAN系统中存储空间共享冲突产生原因和表现形式的基础上,给出了解决这一难题的分布式和集中控制两种基本方法,并融合了集中控制的网络文件系统、三方传送和软件RAID等技术,提出并实现了FC3HPN系统,该系统在具备较高性能的同时,首次实现了元数据共享。Problem of storage space sharing conflict is the key problem of SAN management. To resolve it, two basic methods of distributed and center-controlled are given based on analysing its generating reason and representation. FC3HPN (fibre channel center-controlled high performance network) is given and realized with the center-controlled network file system, three party transfer and software RAID. The performance of the system is very high and metadata sharing is realized for the first time.
