Hello Tenaro, Today you cannot run Fibre Channel or FCoE over Cisco ACI. If you are using traditional Fibre Channel, you will be running it over a separate physical and SAN switching infrastructure. If you are using FCoE, there are options. For example, if you leverage Cisco UCS B-series blade servers, you can connect UCS Fabric Interconnect to your ACI leaf node for network and/or IP storage connectivity, and to upstream SAN switching infrastructure for either FC or FCoE storage access. In this case FCoE traffic arriving from the blade server to the Fabric Interconnect will be split with network and/or IP storage traffic being forwarded to ACI and FC/FCoE traffic to the SAN switching infrastructure. Something like this: I hope that clarifies things for you! Thank you, David Klebanov @DavidKlebanov

Hello Daniel, Thank you for your question. Unified Fabric approach consolidates network and storage traffic over single unified infrastructure. As today's Data Center fabrics grow in size by adding sometimes significant amount of Top of Rack switches, there is a need to adequetly accommodate the growth of the FCoE environment as well. Features, such as FCoE-NPV, allow building scaled out multi-hop unified fabric topologies, which adhere to SAN and Ethernet best practices alike. More specifically, in FCoE multi-hop topology there are access layer and aggregation/core layer switches. Access layer switches connect to initiators or target, while aggregation/core layer switches provide aggregation points for storage connectivity. With FCoE-NPV, access layer switches are put in "proxy" mode, where they neither participate in Fibre Channel switching nor process Fibre Channel logins (FLOGIs). In this mode they also don't consume Domain IDs or perform zoning, which are often times the most significant contributors to allowing overall larger scale. Aggregation/core layer switches run FCoE-NPIV, which allows them allocate multiple Fibre Channel IDs (FCIDs) over a single physical interface (the one connected to the access layer switch running in FCoE-NPV mode). Cisco Nexus 5K/6K and UCS Fabric Interconnect can operate in FCoE-NPV mode, while Nexus 7K and MDS 9700 are likely FCoE-NPIV devices. You can learn more about FCoE-NPV by reading through the latest configuration guide for the Nexus 5600 switches or reading our CCNA Data Center 640-916 Certification Guide, when it becomes available in a few days. http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5600/sw/fcoe/7x/b_5600_FCoE_Config_7x.html http://www.ciscopress.com/store/ccna-data-center-dcict-640-916-official-cert-guide-9781587144226 Hope that helps!
