Enabling deep analysis of equipment utilizing high-bandwidth protocols such as SMB, NFS, iSCSI, FCIP, and iFCP requires complete and accurate data capture which is beyond the capability of software-based analyzers. The Xgig^® iSCSI protocol analysis is part of the Gigabit Ethernet protocol analyzer solution from Finisar. Xgig, designed for heavy-duty data traffic and complicated network structures, offers the industry a reliable analysis tool for high-bandwidth protocols such as GbE and iSCSI. Xgig analysis system streamlines resolution of events that cause performance problems and enables users to design, implement, test, and evaluate the protocols.
