Paper covers cabling architectures for FCoE
Technical document from Corning Cable Systems explains the migration pattern from first- to third-generation Fibre Channel over Ethernet.
A technical paper offered by Corning Cable Systems includes discussion of the cabling architectures that can be used to support Fibre Channel over Ethernet (FCoE) in data center environments. The paper defines FCoE and charts the throughput capacity of current-generation FCoE (10 Gbits/sec), along with anticipated future-generation (40- and 100-Gbit/sec) speeds for the application.
"FCoE is simply a transmission method in which the Fibre Channel frame is encapsulated into an Ethernet frame at the server," the paper explains, later adding, "Fibre Channel encapsulation requires use of 10 Gigabit Ethernet transmission electronics as well as provides for increased server to SAN connectivity."
Of the four-page paper, approximately three pages are devoted to cabling architectures that can be used to support FCoE. It diagrams and explains logical first-, second- and third-generation FCoE architectures, which will evolve as FCoE network gear migrates toward the network's core.
