<p>A virtual Fibre Channel over Ethernet (FCoE) forwarder (vFCF) distributed in the core layer of an FCoE environment between two or more FCoE-enabled core switches by using a single virtual domain ID for the FCoE forwarders (FCFs) in a fabric is provided. In this manner, the network problem of having a single point of failure in a fabric is eliminated without needing to double the number of core switches in the FCoE environment for redundancy. Because the login and state information is distributed between the FCoE-enabled core switches of a fabric, the loss or failure of a core switch no longer means that the fabric goes down. Instead, when a core switch fails, the hosts and initiators may stay logged in through the other core switches.</p> |
