Integrated Lights-Out 3 technology

Introduction

HP Integrated Lights-Out 3 (iLO 3) helps you meet demands for IT efficiency and responsiveness,

especially in corporate data centers. iLO 3 is an autonomous management subsystem residing on select

HP ProLiant and BladeSystem servers. It provides you with secure remote management capabilities,

regardless of server status or location. iLO 3 provides alerts, server status, power information, power

management, and remote control capabilities to diagnose OS or server problems remotely.

You can take advantage of the full functionality of iLO 3 by purchasing an iLO Advanced license or

purchasing Insight Control, the HP ProLiant lifecycle management solution. Refer to

http://h18013.www1.hp.com/products/servers/management/ilo_table.html to see the supported

capabilities in each licensing options.

This paper briefly discusses enhancements to iLO 3 beyond the previous iLO 2 capabilities. It describes

the iLO 3 architecture and its technologies that provide comprehensive remote management capabilities.

See the final section of this paper for more references about iLO technology.

iLO 3 enhancements

iLO 3 improves performance and expands functionality compared to iLO 2, including:

 Faster processor provides better response and faster virtual media, thread and process protection, and

the horsepower to support current and future management features.

 Faster processor and USB 2.0 give the virtual media a 3-5x performance increase

 AES encryption engine provides the benefit of strong encryption without the typical performance impact

to system processor

 Firmware improvements

– Green Hills INTEGRITY Real Time Operating System (RTOS)

– Kernel and application code now run in protected address spaces

 The dual-MAC architecture provides an out-of-box shared management port; this means that there is no

need to run the configuration utility before you first log in to iLO 3.

 Improved Windows Integrated Remote Console

– 8x performance increase over iLO 2

– .NET framework allows a more robust GUI and broader browser support—previous ActiveX controls

limited the Windows remote console to Internet Explorer

– Updated SSL and SSH for restricting access and encrypting data

– JavaScript Object Notation (JSON) technology updates using push technology, meaning system

information is updated dynamically and is always current

 New GUI web interface including a tree view structure that make it easier to navigate

 The new user interface includes multi-monitor support and has a scalable display that lets you work with

less searching and scrolling.
