Fibre Channel over Ethernet, FCoE Topology

BLADEOS 6.5.2 Application Guide

Fibre Channel over Ethernet

Fibre Channel over Ethernet (FCoE) is an effort to converge two of the different physical networks in today’s data centers. It allows Fibre Channel traffic (such as that commonly used in Storage Area Networks, or SANs) to be transported without loss over 10Gb Ethernet links (typically used for high-speed Local Area Networks, or LANs). This provides an evolutionary approach toward network consolidation, allowing Fibre Channel equipment and tools to be retained, while leveraging cheap, ubiquitous Ethernet networks for growth.

With server virtualization, servers capable of hosting both Fibre Channel and Ethernet applications will provide advantages in server efficiency, particularly as FCoE-enabled network adapters provide consolidated SAN and LAN traffic capabilities.

The RackSwitch G8124 with BLADEOS 6.5 software is compliant with the INCITS T11.3, FC-BB-5 FCoE specification.

The FCoE Topology

In an end-to-end Fibre Channel network, switches and end devices generally establish trusted, point-to-point links. Fibre Channel switches validate end devices, enforce zoning configurations and device addressing, and prevent certain types of errors and attacks on the network.

In a converged FCoE network where Fibre Channel devices are bridged to Ethernet devices, although the direct point-to-point assurances normally provided by the Fibre Channel fabric may be lost in the transition between the different network types, the G8124 provides a solution.
