Abstract

HP Integrated Lights-Out is an autonomous management subsystem residing on select HP ProLiant and
BladeSystem server platforms. It provides system administrators with secure remote management
capabilities, regardless of server status or location. This technology brief discusses the architecture of
Integrated Lights-Out processors. It also describes key technologies that provide comprehensive
remote management capabilities.
Additional papers about Integrated Lights-Out technology are available from the HP website at
www.hp.com/servers/technology. The final section of this brief titled "For more information" includes
references to specific Integrated Lights-Out web pages and other related material.

Introduction

The globalization of business and proliferation of industry-standard servers have made it impractical
to administer servers locally. To meet increasing demands for IT efficiency and responsiveness, the
need for remote management is critical, especially in corporate data centers. Integrated Lights-Out
(iLO) technology provides hardware-based system management capabilities that enable IT
administrators to control HP ProLiant and BladeSystem servers remotely.
Because iLO is integrated into the server platform, it can provide alerts, server status, power
information, and remote control, regardless of the state of the operating system (OS) or the host
server. Administrators can manage HP ProLiant and BladeSystem servers remotely through their entire
life cycle (initial deployment, operation, and redeployment). Software and firmware can be updated
over the network, and OS or server problems can be diagnosed remotely. The technology within iLO
provides administrators with multiple options for accessing and managing their servers.

Naming conventions and capabilities

Integrated Lights-Out 2 (iLO 2) is the fourth generation in the HP product line for Lights-Out
management and builds on the successful first-generation iLO management processor. In this
technology brief, the iLO designation refers to the general technology or functionality available with
both products: first-generation iLO and iLO 2. A designation of first-generation iLO or iLO 2 indicates
that the functionality is exclusive to that product.
This brief discusses the capabilities supported in the iLO architecture. Some capabilities are supported
by the iLO architecture but are only enabled with iLO Advanced for BladeSystem or iLO Advanced
licensing keys. To determine which capabilities are supported in each of these licensing options, refer
to the HP website www.hp.com/servers/ilo.
