CASE STUDY
QLogic Uses Finisar's Xgig Network Analyzers to Test and Troubleshoot iSCSI SANs . QLogic Corporation (Nasdaq: QLGC) simplifies the process of networking storage for OEMs, resellers and systems integrators with the only endto-end SAN infrastructure in the industry. The company serves customers with solutions based on all storage network technologies including iSCSI, SCSI, and Fibre Channel.
With the emergence of the new industry standard iSCSI protocol, Ethernet networks can now be utilized to effectively build SANs. iSCSIbased SANs provide many of the same benefits as Fibre Channel SANs, but they use TCP/IP and standard Ethernet infrastructures, which are more familiar to many IT managers. In addition, iSCSI enables seamless integration to wide area networks (WANs), enabling new applications such as remote storage. iSCSI is emerging as useful in both stand-alone SANs or as a means to connect Fibre Channel SANs over long distance. The iSCSI marketplace is quickly gaining wide industry support, with products from new storage start-ups and established players such as Microsoft, Cisco, Network Appliance, EMC, and McData. Several established storage vendors have new products in development and test. QLogic is the industry leader in iSCSI design wins, with ASIC and HBA products already available and more than a dozen OEM customer storage systems under development. QLogic's SANblade iSCSI host bus adapters (HBAs) are the newest addition to QLogic's award-winning line of SCSI and Fibre Channel adapter products. "We recognized early on that iSCSI was going to become an important SAN technology. It gives IT managers additional flexibility when designing their SANs, and allows QLogic to provide our customers with the ability to implement both Fibre Channel and iSCSI SANs as appropriate for their needs," said Hugo Oregel, a QLogic firmware engineer. "Additionally, iSCSI is just the first of several applications that will use our TOE (TCP Offload Engine) technology. We continue to develop and implement with customers other emerging uses, such as RDMA and general TCP offload."
