摘要
FC-SAN存在着传播距离有限、成本高、管理困难等不足,IP-SAN的出现解决了FC-SAN的不足.通过对IP-SAN的体系结构和性能的研究,发现沿用FC-SAN体系结构的IP-SAN存在共享冲突、系统和数据不安全等问题.由于IP-SAN中的用户网与存域网在逻辑上属于不同的网络,但在物理上是同一网络.采用三方传送协议实现IP-SAN可以解决这些问题,实验表明这种方法是可行的.
There are some defects such as limited distance?more cost and management difficulty about FC-SAN. The appearance of IP-SAN is to overcome these defects. By studying IP-SAN's architecture and performance, it is obvious that IP-SAN have some problem like sharing conflict?non-security of system and data if it uses FC-SAN's architecture. Because the user network and the storage network of IP-SAN are different in logic but the same one in physic. Those problems will be solved with Third Party Transfer protocol and it is proved by experiment.
