Converged Network Adapter
QLogic adapter that supports both data
networking (TCP/IP) and storage
networking (Fibre Channel) traffic on a
single I/O adapter using two new technolo-
gies: Enhanced Ethernet and Fibre
Channel over Ethernet (FCoE).
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 Fibre Channel, a target
device.
driver
The software that interfaces between the
file system and a physical data storage
device or network media.
DS-1
Digital signal 1 (DS-1, also known as T1
and DS1) is a T-carrier signaling scheme
that is a widely-used standard in telecom-
munications to transmit voice and data
between devices. Technically, DS1 is the
logical bit pattern used over a physical T1
line; however, the terms DS1 and T1 are
often used interchangeably.
DS-3
Digital signal 3 (DS-3) is a digital signal
level 3 T-carrier. It may also be referred to
as a T3 line.
E_Port
Expansion port. A port in a Fibre Channel
switch that connects to another Fibre
Channel switch or bridge device by an
inter-switch link. E_Ports are used to link
Fibre Channel 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 a Fibre Channel fabric
switch provides a point-to-point link attach-
ment to a single N_Port. F_Ports are inter-
mediate 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
Fibre Channel fabric switch.
fabric
A fabric consists of cross-connected Fibre
Channel devices and switches.
fabric port
See F_Port.
fabric switch
Also, switched fabric. A fabric switch
connects multiple devices from indepen-
dent Fibre Channel-arbitrated loops
(FC-ALs) and point-to-point topologies into
a fabric using Fibre Channel switches.
