摘　　要：iSCSI是一种在Internet协议网络上,特别是以太网上进行数据块传输的标准。简单地说,iSCSI可以实现在IP网络上运行SCSI协议,使其能够在高速千兆以太网上进行路由选择。在当前网络存储的需求日益高涨的前提下,由于其标准成熟通用、安装及维护成本较低、良好的可扩展性以及快速高效等特点,性能明显高于当前的DAS、NAS、SANS三种存储模式使其有望成为将来网络存储的主要模式。Internet SCSI (iSCSI) is a standard protocol for data block transmission over Internet protocol(IP) net- works,especially over ethernet,briefly speaking,iSCSI is able to execute SCSI contracts over an IP network and make the route selection over Ethernet with a Kilo-Gigabit high speed. With the current increasing demand for network storage,iSCSI is obviously better than the current three storage models of DAS,NAS,and SANs,because of its advan- tages of common and mature standards, low-cost installation and maintenance, good expandability, as well as high speed and high efficiency. This makes iSCSI have high potential to become a main model for network storage in the future.
