GL - Master Glossary & Acronym List
Since these IQNs are rather unwieldy, initiators and targets also use short, user friendly
names (sometimes called alias names or just aliases).
iSCSI
Short for
Internet SCSI
. iSCSI is an IP-based storage networking standard for linking data
storage facilities. iSCSI is a standard that defines the encapsulation of SCSI packets in TCP
and then routing it using IP. It allows block-level storage data to be transported over widely
used IP networks.
iSNS Server
Short for
Internet Storage Name Service
Server. A protocol enabling the automatic discovery,
configuration, and management of iSCSI devices on a TCP/IP network.
Kerberos
A secure method for authenticating a request for a service used by ADS. Kerberos lets a user
request an encrypted “ticket” from an authentication process that can then be used to request
a service from a server. The user credentials are always encrypted before they are transmitted
over the network.
In Windows 2000/XP, the domain controller is the Kerberos server. The Kerberos key
distribution center (KDC) and the origin of group policies are applied to the domain.
LAN
Short for
Local Area Network
.
A network connecting computers in a relatively small area such
as a building.
LCD
Short for
Liquid Crystal Display
. An electronic device that uses liquid crystal to display
messages.
LED
Short for
Light-Emitting Diode
. An LED is a type of diode that emits light when current
passes through it. Visible LEDs are used as indicator lights on electronic devices.
Linux
A UNIX-like operating system that was designed to provide personal computer users a free or
very low-cost operating system comparable to traditional and usually more expensive UNIX
systems.
Load Balancing
A process available only in multi-Ethernet configurations. The Ethernet port transmission
load is distributed among two or more network ports (assuming the cards are configured for
load balancing). An intelligent software adaptive agent repeatedly analyzes the traffic flow
from the server and distributes the packets based on destination addresses.
MAC Address
Short for
Media Access Control address
, a hardware address that uniquely identifies each
node of a network. In the Open Systems Interconnection (OSI) model, one of two sublayers of
the Data Link Control layer concerned with sharing the physical connection to the network
among several computers. Each Ethernet port has a unique MAC address.
