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.
GUI
Acronym for graphical user interface.
HIP
Acronym for the Dell Hardware Instru-
mentation Package. HIP provides
seamless integration with the Intel

host adapter
A 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/O
Abbreviation 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-band
Communication across the network
between the console and server.
IP
Abbreviation for Internet Protocol.
IPX
Abbreviation for Internetwork Package
Exchange.

current is passed through it.
MB
Abbreviation for megabyte(s). A
megabyte equals 1,024kilobytes or

referring to hard-disk drive storage, th e
