DCB
Data center bridging. Provides enhance-
ments to existing 802.1 bridge specifica-
tions to satisfy the requirements of
protocols and applications in the data
center. Because existing
high-performance
data centers typically comprise multiple
application-specific networks that run on
different link layer technologies (Fibre
Channel for storage and Ethernet for
network management and LAN connec-
tivity), DCB enables 802.1 bridges to be
used for the deployment of a converged
network where all applications can be run
over a single physical infrastructure.
DCBX
Data center bridging exchange. A protocol
used by DCB devices to exchange config-
uration information with directly connected
peers. The protocol may also be used for
misconfiguration detection and for configu-
ration of the peer.
device
A computer subsystem, such as an
adapter card, that mediates data in a
computer network. The term device is
used interchangeably with target and
target device.
DHCP
Dynamic host configuration protocol.
Enables computers on an IP network to
extract their configuration from servers
that have information about the computer
only after it is requested.
driver
The software that interfaces between the
file system and a physical data storage
device or network media.
dynamic host configuration protocol

enhanced transmission selection
See ETS.
Ethernet
The most widely used LAN technology that
transmits information between computer,
typically at speeds of 10 and 100 million
bits per second (Mbps).
ETS
Enhanced transmission selection. A
standard that specifies the enhancement
of transmission selection to support the
allocation of bandwidth among traffic
classes. When the offered load in a traffic
class does not use its allocated bandwidth,
enhanced transmission selection allows
other traffic classes to use the available
bandwidth. The bandwidth-allocation prior-
ities coexist with strict priorities. ETS
includes managed objects to support
bandwidth allocation.
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

firmware
Low-level software typically loaded into
read-only memory and used to boot and
operate an intelligent device.
