S
command line interface (CLI)
Program interface driven by entering
commands and parameters.
CRC
Cyclic redundancy check. A type of check
value designed to catch most transmission
errors.
CSV file
Comma separated values file.
device
A target, typically a disk drive. Hardware
such as a disk drive, tape drive, printer, or
keyboard that is installed in or connected
to a system. In FC, a target device.
driver
The software that interfaces between the
file system and a physical data storage
device or network media.
E_Port
Expansion port. A port in an FC switch that
connects to another FC switch or bridge
device by an inter-switch link. E_Ports are
used to link FC switches to form a
multi-switch fabric.
EEPROM
Electrically erasable programmable
read-only memory. Memory that can be
erased (entirely, not selectively) using
higher electrical voltages.
Enhanced Ethernet
Also called data center Ethernet or
converged enhanced Ethernet. Refers to
new enhancements to the existing
Ethernet standard that eliminate Ethernet’s
inherently lossy nature and make 10Gb
Ethernet a viable storage networking
transport.
F_Port
The fabric port in an FC fabric switch
provides a point-to-point link attachment to
a single N_Port. F_Ports are intermediate
ports in virtual point-to-point links between
end ports, for example N_Port to F_Port to
F_Port to N_Port using a single FC fabric
switch.
fabric
A fabric consists of cross-connected FC
devices and switches.
fabric port
An F_Port or FL_Port.
fabric switch
Also, switched fabric. A fabric switch
connects multiple devices from indepen-
dent FC-arbitrated loops (FC-ALs) and
point-to-point topologies into a fabric using
FC switches.
failover path
Software feature that ensures data avail-
ability and system reliability by assigning
alternate path and automatic adapter
failover for device resources. This feature
is available only in Windows
2000/Windows Server 2003/Windows
Vista, Novell NetWare, and Red Hat/SuSE
Linux. (Windows XP and Windows Server
2008 do not support failover.)
FC
Fibre Channel is a high-speed serial inter-
face technology that supports other higher
layer protocols such as SCSI and IP.
