On an FCoE network, communication between ENodes can be controlled using zones to improve the network security.


A zone contains multiple members, and an ENode can join different zones. Members in the same zone can communicate with each other, whereas members in different zones cannot.

You can use the following items to define zone members:

  • Zone alias: After a zone alias is added to a zone, members associated with the zone alias are also added to the zone.

  • FC_ID: On an FC network, ENodes use FC_IDs to communicate with each other.

  • FCoE interface: On an FCoE network, ENodes use FCoE interfaces to exchange information with each other.

  • World Wide Node Name (WWNN): A WWNN is a 64-bit address that identifies an ENode on an FC network.

  • World Wide Port Name (WWPN): A WWPN is a 64-bit address that identifies an ENode interface on an FC network.

Figure 2-9 Networking of zones

As shown in Figure 2-9, ENodes are added to different zones to control access of ENodes. For example, ArrayB can communicate with only ServerB and ServerC, but cannot communicate with ServerA.

Zone Set

A zone set contains multiple zones, each of which can join multiple zone sets. Zones in a zone set take effect only after the zone set is activated. Only one zone set can be activated at any given time in one instance.

Zone Alias

A zone alias is used to simplify the zone configuration. When multiple member nodes need to be added to multiple zones, create a zone alias, associate the member nodes with the zone alias, and add the zone alias to the zones. In this case, you do not need to add each node to each zone one by one.

Figure 2-10 Networking of the zone alias

As shown in Figure 2-10, if MemberC and MemberD need to join ZoneA and ZoneB, to simplify configurations, add MemberC and MemberD to Zone aliasA and then add Zone aliasA to ZoneA and ZoneB.
