Fibre Channel over Ethernet for FC Flex IO Modules
FCoE provides a converged Ethernet network that allows the combination of storage-area network (SAN) and LAN trac on a Layer 2 link
by encapsulating Fibre Channel data into Ethernet frames.
The Fibre Channel (FC) Flex IO module is supported on Dell Networking Operating System (OS) I/O Aggregator (IOA). The IOA switch
installed with the FC Flex IO module functions as a top-of-rack edge switch that supports converged enhanced Ethernet (CEE) trac —
Fibre channel over Ethernet (FCoE) for storage, Interprocess Communication (IPC) for servers, and Ethernet local area network (LAN) (IP
cloud) for data — as well as FC links to one or more storage area network (SAN) fabrics.
FCoE works with the Ethernet enhancements provided in Data Center Bridging (DCB) to support lossless (no-drop) SAN and LAN trac.
In addition, DCB provides exible bandwidth sharing for dierent trac types, such as LAN and SAN, according to 802.1p priority classes of
service. DCBx should be enabled on the system before the FIP snooping feature is enabled.
All of the commands that are supported for FCoE on the I/O Aggregator apply to the FC Flex IO modules. Similarly, all of the conguration
procedures and the settings that are applicable for FCoE on the I/O Aggregator are valid for the FC Flex IO modules.
