Fabric device
management interface
(FDMI)
An interface by which device host bus adapters (HBAs) can be managed through the
fabric.
Fabric management
switch
The switch through which the fabric is managed.
Fabric security A feature that provides security for fabric users and devices, including user account security
and fabric services. See Device security and Fabric services.
Fabric services A component of fabric security that provides for the control of inband management and
SNMP on a switch. See Fabric security and Simple Network Management Protocol
(SNMP).
FC port Fibre Channel port
FL_Port Fabric loop port. A Fibre Channel switch port that supports a connection to up to 126
server or storage devices.
Flash memory Memory on the switch that contains the switch control firmware.
Frame Data unit consisting of start-of-frame (SOF) delimiter, header, data payload, CRC, and
end-of-frame (EOF) delimiter.
Group A list of device worldwide names that are authorized to attach to a switch. There are three
group types: one for other switches (ISL), another for devices (port), and a third for devices
issuing management server commands (MS).
Heartbeat LED A switch LED that indicates the status of the internal switch processor and the results of the
Power-on self test.
Host bus adapter (HBA) A circuit board that is installed in a server or storage device through which the device
connects to the fabric.
Inband management The ability to manage a switch through another switch over an inter-switch link.
Initiator The device that initiates a data exchange with a target device.
In-order-delivery A feature that requires that frames be received in the same order in which they were sent.
Input power LED A switch LED that indicates that the switch logic circuitry is receiving proper DC voltages.
Inter-Fabric Zone (IFZ) A zone that is used to map local devices to devices on a remote HP StorageWorks B-series
or C-series fabric across a TR_Port. The zone membership consists of the port WWNs of the
local device, the remote device, and the TR_Port. The zone name is a concatenation of the
IFZ prefix, the lowest WWN, and the remaining WWN, separated by underscores (_).
Inter-switch link (ISL) The connection between two switches using E_Ports. See E_Port.
License key A code associated with a separately-purchased feature that activates that feature on the
switch.
Light Emitting Diode
(LED)
One of several small lights that indicate the condition of the switch or a Fibre Channel port.
See Heartbeat LED, Input power LED, System Fault LED, Activity LED, and Logged-in LED.
Logged-in LED A Fibre Channel port LED that indicates the logged-in or initialization status of the
connected devices.
Maintenance button Momentary button on the switch used to reset the switch or place the switch in maintenance
mode. See Maintenance mode.
Maintenance mode Maintenance mode sets the IP address to 10.0.0.1 and provides access to the switch for
maintenance purposes.
Management
Information Base (MIB)
A set of guidelines and definitions for SNMP functions. See Simple Network Management
Protocol (SNMP).
Management station Workstation or server used to run Simple SAN Connection Manager.
N_Port Node port. A Fibre Channel device port in a point-to-point or fabric connection.
Network Time Protocol
(NTP)
A network protocol that enables a client to synchronize its time with a server.
NL_Port
Node loop port. A Fibre Channel device port that supports arbitrated loop protocol.
