Abbreviation for megahertz.
MIB
Acronym for management information
base.
MIF
Acronym for management information
format. MIF is a file that contains informa-
tion, status, and links to component
instrumentation. MIF files are installed
into the MIF database by the service layer.
The content of a MIF is defined by a DMTF
working committee and is published in
the form of a MIF definition document.
This document identifies the groups and
attributes that are relevant to DMI-
manageable components.
PLUURULQJ
A type of data redundancy that uses a set
of physical drives to store data and one or
more sets of additional drives to store du-
plicate copies of the data. Mirroring is the
preferred data redundancy technique in
lower-capacity systems and in systems
where performance is extremely impor-
tant. See also guarding, RAID 1, and
RAID10.
NIC
Abbreviation for network interface
controller.
NLM
Abbreviation for NetWare Loadable
Modu le.
NNM SE
Abbreviation for Network Node Manager
Special Edition.
NTSF
Abbreviation for the NT File System op-
tion in the Windows NT operating system.
out-of-band
Communications that use a remote assis-
tance card to remotely manage a server
using a modem or an on-board NIC on the
card. The out-of-band path is used for
remote management of a server or for ac-
cessing server information when the
server or network is down.
parameter
A value or option that you specify to a pro-
gram. A parameter is sometimes called a
switch
or an
argument
.
PCI
Abbreviation for Peripheral Component
Interconnect.
peripheral device
An internal or external device—such as a
printer, a disk drive, or a keyboard—con-
nected to a computer.
POST
Acronym for power-on self-test. Before
the operating system loads when you turn
on your computer, the POST tests various
system components such as RAM, the
disk drives, and the keyboard.
PSPB
Abbreviation for power-supply paralleling
board.
RAID
Acronym for redundant array of indepen-
dent disks. This phrase was introduced by
David Patterson, Garth Gibson, and Randy
Katz at the University of California at Ber-
keley in 1987. The goal of RAID is to use
multiple small, inexpensive disk drives to
provide high storage capacity and perfor-
mance while maintaining or improvin g the
reliability of the disk subsystem.
Patterson, Gibson, and Katz described
five different methods, which are known
as RAID levels 1 through 5. Each level
uses one or more extra drives to provide
a means of recovering data lost when a
disk fails, so that the effective failure rate
of the whole disk subsystem becomes
very low.
Recently, Katz has defined a sixth meth-
od, RAID 6, which improves reliability
even further, and a configuration that pro-
vides no data recovery has popularly
become known as RAID 0.
