随着计算机系统中处理器和磁盘驱动器技术的发展,计算速度和存储容量已经发展到相当程度,惟有I/O等环节存在的瓶颈仍然制约着存储系统向终端用户提供实时的数据存取能力。此外,Internet信息量和业务量的爆炸性增长也向企业提出了如何让它们的数据在任何时候都能够在全球IP网络上可用的挑战。iSCSI便应运而生,它作为在IP网络上访问整块(Block-level)数据的新的Internet SCSI标准,正逐步扩大着在SAN和NAS市场的应用。 With the development of processor and disk drive technology in computer systems, computational speed and storage capacity have been developed to a considerable extent. Only the bottlenecks in I / O and other fields still restrict the storage system to provide end users with real-time data access capability. In addition, the explosive growth in the volume and volume of Internet traffic presents companies with the challenge of making their data available to global IP networks at all times. iSCSI came into being as its new Internet SCSI standard for accessing block-level data over IP networks, and is expanding its use in the SAN and NAS markets.
