Fibre Channel
A high-speed serial interface technology
that supports other higher layer protocols
such as SCSI and IP.
Fibre Channel over Ethernet
See FCoE.
Internet Protocol
See IP.
Internet small computer system interface
See iSCSI.
IP
Internet Protocol. A method by which data
are sent from one computer to another
over the Internet. IP specifies the format of
packets, also called datagrams, and the
addressing scheme.
iSCSI
Internet small computer system interface.
Protocol that encapsulates data into IP
packets to send over Ethernet connec-
tions.
management workstation
PC workstation used to manage routers
remotely by connecting to the routers
using the QConvergeConsole GUI or CLI
commands.
path
A path to a device is a combination of a
adapter port instance and a target port as
distinct from internal paths in the fabric
network. A fabric network appears to the
operating system as an opaque network
between the adapter (initiator) and the
target.
Because a path is a combination of an
adapter and a target port, it is distinct from
another path if it is accessed through a
different adapter or it is accessing a
different target port. Consequently, when
switching from one path to another, the
driver might be selecting a different
adapter (initiator), a different target port, or
both.
This is important to the driver when
selecting the proper method of failover
notification. It can make a difference to the
target device, which might have to take
different actions when receiving retries of
the request from another initiator or on a
different port.
port
Access points in a device where a link
attaches. The four major port types are:
 N_Port—a Fibre Channel port that
supports point-to-point topology.
 NL_Port—a Fibre Channel port that
supports loop topology.
 F_Port—a port in a fabric where an
N_Port can attach.
 FL_Port—a port in a fabric where an
NL_Port can attach.
port instance
The number of the port in the system.
Each adapter may have one or multiple
ports, identified with regard to the adapter
as port 0, port 1 and so forth. To avoid
confusion when dealing with a system
containing numerous ports, each port is
assigned a port instance number when the
system boots up. So Port 0 on an adapter
might have a port instance number of 8, for
example, if it is the eighth port discovered
by the system.
