HP Integrity iLO 3 Operations Guide

G
gateway A computer or program that interconnects two networks and passes data packets between the
networks. A gateway has more than one network interface.
gateway address Where the packet needs to be sent. This can be the local network card or a gateway (router) on
the local subnet.
GUI Graphical User Interface. An interface that uses graphics, along with a keyboard and mouse, to
provide easy-to-use access to an application.
H
host A system, such as a backend server, with an assigned Internet Protocol (IP) address and host
name. The host is accessed by other remote systems on the network.
host console The interface between iLO 3 and the server that controls basic functionality. Also known as
console.
host ID Part of the 32-bit Internet Protocol (IP) address used to identify a host on a network. Host ID is
also known as DNS Name or Host Name.
host name The name of a particular machine within a domain. Host names always map to a specific Internet
Protocol (IP) address.
HTTP Hypertext Transfer Protocol. The Internet protocol that retrieves hypertext objects from remote
hosts. HTTP messages consist of requests from client to server, and responses from server to client.
HTTP is based on Transmission Control Protocol/Internet Protocol (TCP/IP).
I
in-band system
management
A server management capability that is enabled only when the operating system is initialized
and the server is functioning properly.
Integrated
Lights-Out (iLO)
The iLO functionality offers remote server management through an independent management
processor (MP). Integrity 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 or in a remote system to comprehend
the environmental makeup of the system and to register with the 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 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.
