DCBX
Data center bridging exchange protocol.
Used by data center bridging (DCB)
devices to exchange configuration infor-
mation with directly connected peers. The
protocol may also be used for misconfigu-
ration detection and for configuration of
the peer.
device
A
, 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.
DHCP
Dynamic host configuration protocol.
Protocol used by networked devices
(clients) to obtain various parameters
necessary for the clients to operate in an
network.
driver
The software that interfaces between the
file system and a physical data storage
device or network media.

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.
EFI
Extensible firmware interface. A specifica-
tion that defines a software interface
between an operating system and platform
firmware. EFI is a replacement for the
older BIOS firmware interface present in
all IBM PC-compatible personal
computers.
Ethernet
The most widely used LAN technology that
transmits information between computer,
typically at speeds of 10 and 100 million
bits per second (Mbps).
Enhanced Transition Services
Enhanced Transition Services (ETS)
controls the actual bandwidth allocation at
the network port. The bandwidth allocation
under ETS is typically 50 percent for FCoE
traffic and 50 percent for non-FCoE traffic
(NIC + iSCSI). This means that NPAR QoS
allocations among the NIC partitions for a
specific port, allocate a percentage of the
non-FCoE portion of the bandwidth.
eSwitch
The eSwitch (embedded switch) function-
ality provides a basic Layer-2 switch for
Ethernet frames. Each physical port has
one instance of an eSwitch, which
supports all NIC partitions on that physical
port.
