Full Fabric Zoning

Zones
© Copyright Lenovo 2015
The CN4093 supports Fibre Channel zones and zonesets for VLANs operating in
full fabric mode. In NPV gateway mode, zoning is controlled by the upstream full
fabric switch and is not configurable in the NPV gateway VLAN.
Zoning allows logical grouping of ports and storage devices within a storage area
network. Zoning defines access control between groups of servers and storage
devices.
A SAN typically is divided into zones and zonesets, as described in the following
sections.
A zone is a logical grouping of end nodes that are permitted to interact with each
other. Zones can be grouped into a zonesets, which can be activated or deactivated
as a single entity. A zone provides security by restricting access to only those
devices that reside within the zone. Zoning also confines change notification floods
within each zone.
Each zone contains one or more servers and one or more storage devices. Ports and
devices in a zone are called zone members. A zone contains one or more zone
members. A device can belong to one or more zones. End nodes that are members
of a zone can communicate with each other, but they are isolated from nodes in
other zones of which they are not a member.
If no zone is configured for the device, it resides in the default zone. You can
configure the default zone to permit or deny its member devices to communicate
with each other.
You can specify zone members based on any of the following criteria:
 pWWN: The port World Wide Number is a unique ID represting a particular
end node. The pWWN is a 64‐bit hexadecimal value (for example,
20:34:00:80:e5:23:f4:55)
 FC ID: The Fibre Channel identifier (FC ID) specifies the unique fabric domain
ID of a device that connects to a node port on the switch. The FC ID is assigned
by the full‐fabric switch during the connection sequence and can change if the
device logs out of the Fibre Channel fabric and returns. The FC ID is a 24‐bit
hexadecimal value (for example, 0xab00c1), but can also be specified in
hexadecimal dotted notation (for example, ab.00.c1) generally representing
<domain or device>.<area>.<link>
FC alias: The Fibre Channel alias specifies the device that connects to a node

port on the switch. The FC alias is a 1‐64 character text value (for example,
StorageOne).
