multi-switch fabric
Fibre Channel fabric created by linking more than one director or fabric switching device
within a fabric.
name server
Program that translates names from one form into another. Domain name servers (DNS)
translate domain names into IP addresses.
name server zoning
N_Port access management that allows N_Ports to communicate if and only if they belong to a
common name server zone.
network address
Name or address that identifies a managed product on a TCP/IP network. The network address
can be either an IP address in dotted-decimal notation containing four three-digit octets in the
format xxx.xxx.xxx.xxx), or a domain name (as administered on a customer network).
nickname
Alternate name assigned to a world wide name for a node or director in the fabric.
node
In Fibre Channel terminology, node refers to an end device (server or storage device) that is or
can be connected to a switched fabric.
node port
Physical interface within an end device which can connect to an F_Port on a switched fabric or
directly to another N_Port (in point-to-point communications).
non-disruptive maintenance
Ability to service FRUs (including maintenance, installation, removal and replacement) while
normal operations continue without interruption. See also concurrent maintenance.
N_Port
See node port.
offline sequence
Sequence sent by the transmitting port to indicate that it is attempting to initialize a link and
has detected a problem in doing so.
OLS
See offline sequence.
operating state (Director)
The operating states are described as follows:
Online—when the director is set online, an attached device can log in to the director if the port is
not blocked. Attached devices can communicate with each other if they are configured in the same
zone.
