FCoE NPV is supported on the Cisco Nexus devices. It functions similarly to traditional FCoE. The FCoE NPV feature is an enhanced form of FIP snooping that provides a secure method to connect FCoE-capable hosts to an FCoE-capable FCoE forwarder (FCF) switch. The FCoE NPV feature provides the following benefits: FCoE NPV does not have […]

The FCoE standard defines two types of endpoints: FCoE Ethernet Nodes (ENodes) and Fibre Channel Forwarders (FCFs). Figure 9-10 shows a simplified version of an ENode. An ENode (also called a CNA adapter) is a Fibre Channel HBA implemented within an Ethernet NIC. The data-forwarding component that handles FC frame encapsulation/decapsulation is called an FCoE […]
A typical data center has two separate networks: one for Ethernet and one for Fibre Channel storage. These networks are physically and logically separated from each other, as shown on the left in Figure 9-1. Here, a SAN leverages dual fabric with multipathing failover initiated by the client, and a LAN leverages single fully meshed […]
Smart zoning implements hard zoning of large zones with fewer hardware resources than was previously required. The traditional zoning method allows each device in a zone to communicate with every other device in the zone, and the administrator is required to manage the individual zones. Smart zoning eliminates the need to create a single initiator […]
A device alias supports the following two modes: Basic mode: When operating in basic mode, which is the default, the device alias is immediately expanded to a pWWN. This operation continues until the mode is changed to enhanced. In basic mode, when device aliases are changed to point to a new HBA, for example, that […]
