Simultaneously , the san based on fiber channel - arbitrated loop ( fc - al ) has convenience , expansibility , high fault tolerated ability , high reliability and agility of configuration . it can reduce total holding cost effectively 并且它通过引入了光纤通道仲裁环技术( fc - al ) ，使其具有方便性、可扩展性、高容错能力、高可靠性和配置的灵活性，有效减少了总体拥有成本( tco ) 。
In the system , the communication delay is reduced by using the ethernet switch combined the atm switch . the error rate is reduced also because the program of the communication is programmed with the winsock and tcp / ip protocol . 4 为满足电网动态监控系统中对数据传输的要求，采用了atm技术和以太网技术相结合的方式，通过全光纤通道，构建了一套实时、可靠的全网相角信息实时传输系统。
San is defined as a network where storage devices and server devices are connected together by fast links such as optical fiber channels . san can be used to implement integrated management of storage resource , to reduce the management costs , to improve the speed of data access and the efficiency of storage space , and to increase system flexibility and expandability San是使用高速链路(如光纤通道)将存储设备和服务器连接在一起而形成的网络，它可以实现对存储资源的集成化管理，降低了管理成本，提高了存储的速度和效率，存储系统的灵活性和可扩充性更好，不同服务器之间共享存储资源和数据也成为可能。
One idea that has been put forward to solve these problems is the " storage area network " ( san ) , which is defined as a network where storage devices and server devices are connected together by fast links such as optical fiber channels . san can be used to implement integrated management of storage resource , to reduce the management costs , to improve the speed of data access and the efficiency of storage space , and to increase system flexibility and expandability San是使用高速链路(如光纤通道)将存储设备和服务器连接在一起而形成的网络，它可以实现对存储资源的集成化管理，降低了管理成本，提高了存储的速度和效率，使存储系统有更好的灵活性和可扩充性，不同服务器之间共享存储资源和数据也成为可能。
Simultaneously , the san based on fibre channel - arbitrated loop ( fc - al ) has conveniece , expansibility , high fault tolerated ability , high reliability and agility of configuration , and supports heterogeneous servers such as unix , nt and netware to link at the same time so as to be able to reduce total holding cost 同时，基于光纤通道仲裁环技术（ fc - al ）的san具有管理上的方便性、可扩展性、高容错能力、高可靠性和配置的灵活性，并且支持异构服务器unix 、 nt和netware同时连接，能够有效地减少总体拥有成本（ tco ） 。
