support for various platforms is the standardization of the Protocol. With standardized protocols, all types of platform solutions can be followed by the introduction of a common standard of support and products, such a considerable market size can be built up. The SNIa Association formally passed the iSCSI standard in February 2003, and although iSCSI has been formally standardized, it does not necessarily mean that it can be quickly popularized, whether iSCSI can stand firm in the enterprise
