Fibre Channel Over
Ethernet
Overview
In today’s data center, multiple networks, including network attached storage
(NAS), management, IPC, and storage, are used to achieve the desired
performance and versatility. In addition to iSCSI for storage solutions, FCoE can
now be used with capable QLogic C-NICs. FCoE is a standard that allows Fibre
Channel protocol to be transferred over Ethernet by preserving existing Fibre
Channel infrastructures and capital investments by classifying received FCoE and
FIP frames.
The following FCoE features are supported:
Receiver classification of FCoE and FIP frames. FIP is the FCoE
Initialization Protocol used to establish and maintain connections.
Receiver CRC offload
Transmitter CRC offload
Dedicated queue set for Fibre Channel traffic
DCB provides lossless behavior with PFC
DCB allocates a share of link bandwidth to FCoE traffic with ETS
DCB supports storage, management, computing, and communications fabrics
onto a single physical fabric that is simpler to deploy, upgrade, and maintain than
in standard Ethernet networks. DCB technology allows the capable QLogic
C-NICs to provide lossless data delivery, lower latency, and standards-based
bandwidth sharing of data center physical links. The DCB supports FCoE, iSCSI,
Network-Attached Storage (NAS), Management, and IPC traffic flows. For more
