On 3rd June 2009, the FC-BB-5 working group of T11 completed the development of the draft standard and unanimously approved it as the final standard. The following day the plenary session of T11 approved forwarding the FC-BB-5 standard to INCITS for publication as an ANSI standard.

 

Cisco Systems has significantly contributed to the definition of FCoE in the FC-BB-5 standard through multiple technical submissions. Cisco has led the FC-BB-5 working group holding the chairman position with Claudio DeSanti.

One of the most significant technical challenges for the working group has been the definition of the addressing mode for FCoE, with two schemes proposed, FPMAs (Fabric Provided MAC Addresses, proposed by Cisco) and SPMAs (Server Provided MAC Addresses, proposed by Brocade). The final standard recognizes the superiority of the Cisco scheme by stating that FPMAs are the only addresses mandatory to implement.

The standard is at:
