Glossary-2 SN0054671-00 A
device
A computer subsystem, such an adapter
card, which mediates data in a computer
network. The term “device” is used inter-
changeably with “target” and “target
device”.
driver
The software that interfaces between the
file system and a physical data storage
device or network media.
dynamic host configuration protocol
(DCHP)
Enables computers on an IP network to
extract their configuration from servers
that have information about the computer
only after it is requested.
Enhanced Ethernet
Also called data center Ethernet or
converged enhanced Ethernet . Refers to
new enhancements to the existing
Ethernet standard that eliminate Ethernet’s
inherent lossy nature and make 10Gb
Ethernet a viable storage networking
transport.
Ethernet
The most widely used LAN technology that
transmits information between computers,
typically at speeds of 10 and 100 million
bits per second (Mbps).
failover path
Software feature that ensures data avail-
ability and system reliability by assigning
alternate path and automatic adapter
failover for device resources.
Fast! UTIL
QLogic Fast! UTIL™ Fibre Channel
Adapter BIOS utility.
Fibre Channel
High-speed serial interface technology
that supports other higher layer protocols
such as SCSI and IP, and is primarily used
in SANs. Standardized under ANSI in
1994.
Fibre Channel over Ethernet (FCoE)
Fibre Channel over Ethernet. A new
technology defined by the T11 standards
body that allows traditional Fibre Channel
storage networking traffic to travel over an
Ethernet link by encapsulating Fibre
Channel frames inside Layer 2 Ethernet
frames. For more information, visit
www.fcoe.com .
Flash
Nonvolatile memory where the boot code
is saved. At times, Flash and boot code
are used interchangeably.
Internet protocol (IP)
A method by which data is sent from one
computer to another over the Internet. IP
specifies the format of packets, also called
datagrams, and the addressing scheme.
Internet small computer system interface
(iSCSI)
Protocol that encapsulates data into IP
packets to send over Ethernet connec-
tions. An alternative to FCIP.
load balancing
A software feature that improves system
performance by balancing device access
between multiple ports or adapters for
maximum resource efficiency.
local area network (LAN)
Network typically with transmissions less
than 5km.
