Ports are access points in a device where a link
attaches. There are four types of ports, as follows:
N_Port is a Fibre Channel device port that supports
point-to-point topology.
NL_Port is a Fibre Channel device port that supports
loop topology.
F_Port is a port in a fabric where an N_Port can attach.
FL_Port is a port in a fabric where an NL_Port can
attach.
SAN stands for storage area network, which consists
of multiple storage units and servers connected by
networking topology.
SCSI stands for small computer system interface. The
original SCSI specification was a hardware bus
specification and a packet-oriented protocol
specification for communicating on that bus. SCSI over
Fibre Channel uses the packet-oriented protocol to
communicate with storage devices on the Fibre
Channel.
Target binding refers to the process in which the HBA
driver binds a target ID using a target's world wide port
name (WWPN) or port ID. This enables the target ID to
always connect to the WWPN or port ID across reboots
regardless of SAN reconfigurations.
