Benefits of Multihop FCoE
Improve Agility, Simplify Management, and Reduce Costs(4:14 min)
Cisco MDS 9000 Series Switches and Cisco Nexus switches offer LAN-SAN convergence through Fibre Channel over Ethernet (FCoE). Cisco Nexus switches support up to 40 Gigabit Ethernet FCoE and dynamic FCoE using a spine-leaf architecture.
Consolidate, Scale, and Save
A classic data center design features a dedicated Ethernet LAN and a separate, dedicated Fibre Channel (FC) SAN. With FCoE, it is possible to run a single, converged network. As a standards-based protocol that allows Fibre Channel frames to be carried over Ethernet links, FCoE obviates the need to run separate LAN and SAN networks.
FCoE allows an evolutionary approach to I/O consolidation by preserving all Fibre Channel constructs, maintaining the latency, security, and traffic management attributes of Fibre Channel while preserving investments in Fibre Channel tools, training, and SANs. Based on lossless, reliable Ethernet, FCoE networks combine LAN and multiple storage protocols on a converged network.
FCoE also drastically reduces the number of I/O adapters, cables, and switches in the data center, when deployed as an access layer convergence solution. The recent introduction of FCoE support with 10GBASE-T technology allows data centers to have flexible physical cabling while supporting any protocol at much lower costs.
Now, multihop FCoE technology can be used to extend convergence beyond the access layer. The higher, more efficient speeds, such as 40 Gigabit Ethernet FCoE today, or the 100 Gigabit Ethernet FCoE in the future, help enable fewer and higher-speed Inter-Switch Links (ISLs) in the network core. The converged architecture means you can wire once and deploy anywhere to support any storage protocol, including iSCSI or NFS. This consolidated infrastructure also helps to simplify management and significantly reduce total cost of ownership (TCO).
FCoE is one of the core components of the Cisco Unified Data Center, which helps enable multiprotocol networking through Cisco Unified Computing System (UCS), Cisco Nexus platforms, and Cisco MDS platforms.
