Abstract:

A network where FC and Ethernet storage traffic share the underlying network. The network extends FC SAN storage specific attributes to Ethernet storage devices. The network is preferably formed of FC switches, so each edge switch acts as an FCoE FCF, with internal communications done using FC. IP packets are encapsulated in FC packets for transport. Preferably, either each outward facing switch port can be configured as an Ethernet or FC port, so devices can be connected as desired. FCoE devices connected to the network are in particular virtual LANs (VLANs). The name server database is extended to include VLAN information for the device and the zoning database has automatic FCOE_VLAN zones added to provide a mechanism for enhanced soft and hard zoning. Zoning is performed with the conventional zoning restrictions enhanced by including the factor that any FCoE devices must be in the same VLAN.
