HP Integrity iLO 2 Operations Guide

Integrated
Lights-Out (iLO)
The iLO functionality offers remote server management through an independent management
processor (MP). iLO was introduced into most HP Integrity entry class servers in late 2004. Prior
to that, embedded remote server management was referred to as MP functionality. All legacy
MP functionality has been carried forward and combined with new features, all under the heading
of "iLO". Therefore, "iLO" and "MP" mean the same thing for entry class servers.
IP Internet Protocol. IP specifies the format of packets and the packet addressing scheme. Most
networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP),
which establishes a virtual connection between a destination and a source. TCP/IP establishes
a connection between two hosts so that they can send messages back and forth for a period of
time. The format of an IP address is a 32-bit numeric address written as four numbers separated
by periods. Each number can be zero to 255; for example, 1.160.10.240. Within an isolated
network, you can assign IP addresses at random as long as each one is unique. However,
connecting a private network to the Internet requires using registered IP addresses (called Internet
addresses) to avoid duplicates.
IP Address An identifier for a computer or device on a TCP/IP network.
IPMI Intelligent Platform Management Interface. A hardware-level interface specification designed
primarily for the out-of-band management of server systems over a number of different physical
interconnects. The IPMI specification describes extensive abstractions regarding sensors, enabling
a management application running on the operating system (OS) or in a remote system to
comprehend the environmental makeup of the system and to register with the system's IPMI
subsystem to receive events. IPMI is compatible with management software from heterogeneous
vendors. IPMI functionality includes inventory reporting, system monitoring, logging, system
recovery (including local and remote system resets, and power on and power off capabilities),
and alerting.
K
Kernel The core of the operating system (OS) that manages the hardware and provides fundamental
services that the hardware does not provide, such as filing and resource allocation.
KVM Switch Keyboard, Video, Mouse. A hardware device that allows a user, or multiple users, to control
multiple computers from a single keyboard, video monitor and mouse.
L
LDAP Lightweight Directory Access Protocol. A directory service protocol used for the storage, retrieval,
and distribution of information, including user profiles, distribution lists, and configuration data.
LDAP runs over Transmission Control Protocol/Internet Protocol (TCP/IP) across multiple platforms.
Lights-Out
Advanced KVM
card
The HP Lights-Out Advanced KVM card is a PCI-X card that you install into any sx2000-based
mid-range or high-end HP Integrity server such as rx7640, rx8640, and Superdome sx2000.
The Lights-Out Advanced KVM card enables the Lights-Out Advanced IRC and vMedia features
of iLO 2.
The Lights-Out Advanced KVM card is also a KVM card that offers physical video functionality
for servers running Windows, and USB functionality for servers running HP-UX, Windows, and
OpenVMS.
M
Managed Object The actual item in the system environment that is accessed by the provider. For example, a Network
Interface Card (NIC).
Management
Information Base
(MIB)
The MIB defines the properties of the managed object within the device to be managed. Every
managed device keeps a database of values for each definition written in the MIB. MIB is not
the actual database itself and is implementation dependant.
Management
Processor (MP)
The component that provides a LAN interface to the system console and system management.
Prior to iLO 2, embedded remote server management was referred to as MP functionality. All
legacy MP functionality has been carried forward and combined with new features, all under
the heading of "iLO 2". Therefore, "iLO 2" and "MP" mean the same thing for entry class servers.
