JXDUGLQJ
A type of data redundancy that uses a set
of physical drives to store data and a
single, additional drive to store parity data.
Using guarding, the user’s data is
protected from the loss of a single drive.
Guarding is sometimes preferred over
mirroring because it is more cost effective
in systems with a very high storage capac-
ity. However, guarded configurations are
significantly slower for applications that
frequently write to the array, because
each attempt to write to the array requires
multiple read and write commands to
maintain the parity information. If this is a
problem, mirroring or duplexing is a better
choice. See also mirroring, RAID 4, and
RAID 5.
GUIAcronym for graphical user interface.
HIPAcronym for the Dell Hardware Instru-
mentation Package. HIP provides
seamless integration with the Intel
LANDesk Server Manager. Together, HI P
and LANDesk Server Manager allow you
to monitor your Dell servers and track
status information about Dell server
components.
host adapterA host adapter implements communica-
tion between the computer’s bus and the
controller for a peripheral. (Hard-dis k drive
controller subsystems include integrated
host adapter circuitry.) To add a SCSI ex-
pansion bus to your system, you must
install the appropriate host adapter.

Acronym for Internet Information Service.
I/OAbbreviation for input/output. The key-
board and a printer, for example, are I/O
devices. In general, I/O activity can be dif-
ferentiated from computational activity.
For example, when a program sends a
document to the printer, it is engaging in
I/O activity; when the program sorts a list
of terms, it is engaging in computational
activity.
in-bandCommunication across the network
between the console and server.
IPAbbreviation for Internet Protocol.
IPXAbbreviation for Internetwork Package
Exchange.
ISMAbbreviation for Internet Service
Manager.
LANAcronym for local area network. A LAN
system is usually confined to the same
building or a few nearby buildings, w ith all
equipment linked by wiring dedicated
specifically to the LAN.
LDSMAbbreviation for LANDesk Server
Manager.
LEDAbbreviation for light-emitting diode. An
electronic device that lights up when a
current is passed through it.
MBAbbreviation for megabyte(s). A
megabyte equals 1,024kilobytes or
1,048,576bytes; however, when
referring to hard-disk drive storage, th e
