Glossary-2 ISR651103-00 C
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.
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.
electrically erasable programmable
read-only memory
See EEPROM.
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.
Ethernet
The most widely used LAN technology that
transmits information between computer,
typically at speeds of 10 and 100 million
bits per second (Mbps).
expansion port
See E_Port.
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 loop port
See FL_Port.
fabric port
A F_Port or FL_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.
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.)
