iFCP Goals

• Consolidate FC storage switching and routing

functions within the IP fabric to:

– Reduce total cost of ownership – Unify network and storage management domains – Exploit IP technology investment and innovation

• Leverage MPLS, CoS/QoS, ToS, DiffServ,…
• Manage traffic flows between individual FC devices

And… – Extend SAN reach to LAN/MAN/WAN distances

• Next Step

– Prepare rev 01

• Major goals for this revision

– Complete the N_PORT session model – Encapsulation changes for additional end-to-end error detection

• Action Request

– Adopt iFCP as an official IPS work item
