Fibre Channel over Ethernet (FCoE) Technology. FCoE provides an opportunity to reduce data center costs by converging data and storage networking. Standard TCP/IP and Fibre Channel traffic can both run on the same high speed 10Gbps Ethernet wire, resulting in cost savings through reduced adapter, switch, cabling, power, cooling, and management requirements. FCoE has gained rapid market traction because it delivers excellent performance, reduces data center TCO, and protects current data center investment.

iSCSI. The EP8112 even supports iSCSI storage protocol using iSCSI software initiators, which are available with all major operating systems.

High Performance. The EP8112 boosts system performance with 10Gbps speed and full hardware offload for FCoE protocol processing. Cutting edge 10Gbps bandwidth eliminates performance bottlenecks in the I/O path with a 10X data rate improvement versus existing 1Gbps Ethernet solutions. Additionally, full hardware offload for FCoE protocol processing reduces system CPU utilization for I/O operations, which leads to faster application performance and higher levels of consolidation in virtualized systems.

Lower TCO. The EP8112 reduces data center costs through convergence. Now, one ASIC can do the work of both Fibre Channel and Ethernet controllers. This convergence also means fewer cables, fewer switches, less power consumption, reduced cooling, and easier management. The EP8112 also preserves familiar FC concepts such as WWNs, FC-IDs, LUN masking, and zoning, thereby eliminating training costs that are usually required for a new storage technology.

Investment Protection. The EP8112 and FCoE are designed to preserve existing investment in Fibre Channel storage and core Ethernet switches and routers for data networking. The EP8112 also shares a common API with QLogic’s 2500 Series 8Gb FC host bus adapters, making it possible to highly leverage existing initiator and target mode drivers when developing similar drivers for the EP8112.

Unmatched Expertise. QLogic has an unparalleled advantage in delivering this new FCoE technology. QLogic is the undisputed leader in both FC and iSCSI controllers, with years of experience providing FC and Ethernet based products. While some competitors have expertise in either networking or storage, no other I/O provider can match QLogic’s expertise in FC and Ethernet hardware and software solutions.
