NMI - Nonmaskable interrupt. A device sends an NMI to signal the processor about hardware errors. ns - Nanosecond(s). NVRAM - Nonvolatile random-access memory. Memory that does not lose its contents when you turn off your system. NVRAM is used for maintaining the date, time, and system configuration information. OID - Object identifier is an implementation-specific integer or pointer that uniquely identifies an object. parity - Redundant information that is associated with a block of data. parity stripe - In RAID arrays, a striped hard drive containing parity data. partition - You can divide a hard drive into multiple physical sections called partitions with the fdisk command. Each partition can contain multiple logical drives. You must format each logical drive with the format command. PCI - Peripheral Component Interconnect. A standard for local-bus implementation. PDU - Power distribution unit. A power source with multiple power outlets that provides electrical power to servers and storage systems in a rack. PERC - PowerEdge RAID controller. peripheral - An internal or external device, such as a diskette drive or keyboard, connected to a system. pixel - A single point on a video display. Pixels are arranged in rows and columns to create an image. A video resolution, such as 640 x 480, is expressed as the number of pixels across by the number of pixels up and down. POST - Power-on self-test. Before the operating system loads when you turn on your system, the POST tests various system components such as RAM and hard drives. processor - The primary computational chip inside the system that controls the interpretation and execution of arithmetic and logic functions. Software written for one processor must usually be revised to run on another processor. CPU is a synonym for processor. provider - A provider is an extension of a CIM schema that communicates with managed objects and accesses data and event notifications from a variety of sources. PXE - Preboot eXecution Environment. A way of booting a system via a LAN (without a hard drive or bootable diskette). RAC - Remote access controller. 6

NMI
— Nonmaskable interrupt. A device sends an NMI to signal the processor about
hardware errors.
ns
— Nanosecond(s).
NVRAM
— Nonvolatile random-access memory. Memory that does not lose its
contents when you turn off your system. NVRAM is used for maintaining the date,
time, and system configuration information.
OID
— Object identifier is an implementation-specific integer or pointer that
uniquely identifies an object.
parity
— Redundant information that is associated with a block of data.
parity stripe
— In RAID arrays, a striped hard drive containing parity data.
partition
— You can divide a hard drive into multiple physical sections called
partitions
with the
fdisk
command. Each partition can contain multiple logical drives.
You must format each logical drive with the
format
command.
PCI
— Peripheral Component Interconnect. A standard for local-bus
implementation.
PDU
— Power distribution unit. A power source with multiple power outlets that
provides electrical power to servers and storage systems in a rack.
PERC
— PowerEdge RAID controller.
peripheral
— An internal or external device, such as a diskette drive or keyboard,
connected to a system.
pixel
— A single point on a video display. Pixels are arranged in rows and columns to
create an image. A video resolution, such as 640 x 480, is expressed as the number of
pixels across by the number of pixels up and down.
POST
— Power-on self-test. Before the operating system loads when you turn on your
system, the POST tests various system components such as RAM and hard drives.
processor
— The primary computational chip inside the system that controls the
interpretation and execution of arithmetic and logic functions. Software written for
one processor must usually be revised to run on another processor.
CPU
is a synonym
for processor.
provider
— A provider is an extension of a CIM schema that communicates with
managed objects and accesses data and event notifications from a variety of sources.
PXE
— Preboot eXecution Environment. A way of booting a system via a LAN
(without a hard drive or bootable diskette).
