group - As it relates to DMI, a group is a data structure that defines common information, or attributes, about a manageable component. guarding - A type of data redundancy in which a set of physical disks stores data and an additional disks stores parity data. See also mirroring, striping, and RAID. h - Hexadecimal. A base-16 numbering system, often used in programming to identify addresses in the system's RAM and I/O memory addresses for devices. In text, hexadecimal numbers are often followed by h. headless system - A system or device that functions without having a keyboard, mouse, or monitor attached. Normally, headless systems are managed over a network using an Internet browser. host adapter - A host adapter implements communication between the system's bus and the controller for a peripheral device. (Disk controller subsystems include integrated host adapter circuitry.) To add a SCSI expansion bus to your system, you must install or connect the appropriate host adapter. hot-pluggable - The ability to remove a system component or attached device without powering down the system. While a component may be "hot-pluggable," you should never remove a component or device while data traffic is occurring that involves the component. For more information, see the documentation for your specific component or device. Hz - Hertz. I/O - Input/output. A keyboard is an input device, and a monitor is an output device. In general, I/O activity can be differentiated from computational activity. ID - Identification. IDE - Integrated drive electronics. A standard interface between the system board and storage devices. integrated mirroring - Provides simultaneous physical mirroring of two drives. Integrated mirroring functionality is provided by the system's hardware. See also mirroring. internal processor cache - An instruction and data cache built into the processor. 92 Glossary

Glossary
group
— As it relates to DMI, a group is a data structure that defines common
information, or attributes, about a manageable component.
guarding
— A type of data redundancy in which a set of physical disks stores data and
an additional disks stores parity data. See also
mirroring
,
striping
, and

.
h
— Hexadecimal. A base-16 numbering system, often used in programming to
identify addresses in the system’s RAM and I/O memory addresses for devices. In
text, hexadecimal numbers are often followed by

.
headless system
— A system or device that functions without having a keyboard,
mouse, or monitor attached. Normally, headless systems are managed over a network
using an Internet browser.
host adapter
— A host adapter implements communication between the system’s
bus and the controller for a peripheral device. (Disk controller subsystems include
integrated host adapter circuitry.) To add a SCSI expansion bus to your system, you
must install or connect the appropriate host adapter.
hot-pluggable — The ability to remove a system component or attached device
without powering down the system. While a component may be "hot-pluggable," you
should never remove a component or device while data traffic is occurring that
involves the component. For more information, see the documentation for your
specific component or device.
Hz
— Hertz.
I/O
— Input/output. A keyboard is an input device, and a monitor is an output
device. In general, I/O activity can be differentiated from computational activity.
ID
