Background

} FCoE – Fibre Channel over Ethernet (FCoE). } FCF – FCoE Forwarder. } ENode – FCoE end node. } FCF functionality is a bit similar to RBridge in terms of:

§ Forwards Ethernet frames based on higher layer address. § Modifies MAC addresses to reflect next hop.

Background (2)

} The TRILL topology is very similar. } RBridges play similar roles as FCFs.

FCoE with TRILL (1)

} What happens when we have FCoE and TRILL in the same network? } Separate cloud approach:

Host

Ethernet / FCoE RBridge RBridge RBridge RBridge RBridge

TRILL Cloud

Native FC FC Storage Array FCF

Host

Ethernet / FCoE

• FCoE traffic between hosts must

be forwarded through an FCF .

• With separate clouds: goes

through more hops.

• EoR are RBridge – not FCRB.
• Traffic between FCRBs is forwarded
• ver TRILL cloud.
