HPE iLO
The iLO 4 subsystem is a standard component of ProLiant servers that simplifies initial server setup,
server health monitoring, power and thermal optimization, and remote server administration. The iLO 4
subsystem includes an intelligent microprocessor, secure memory, and a dedicated network interface.
This design makes iLO 4 independent of the host server and its operating system.
iLO 4 enables and manages the Active Health System (on page 68) and also features Agentless
Management. All key internal subsystems are monitored by iLO 4. If enabled, SNMP alerts are sent
directly by iLO 4 regardless of the host operating system or even if no host operating system is installed.
Using iLO 4, you can do the following:
•
Access a high-performance and secure Integrated Remote Console to the server from anywhere in
the world if you have a network connection to the server.
•
Use the shared .NET Integrated Remote Console to collaborate with up to four server administrators.
•
Remotely mount high-performance Virtual Media devices to the server.
•
Securely and remotely control the power state of the managed server.
•
Implement true Agentless Management with SNMP alerts from iLO, regardless of the state of the
host server.
•
Download the Active Health System log.
•
Register for HPE remote support.
•
Use iLO Federation to manage multiple servers from one system running the iLO web interface.
•
Use Virtual Power and Virtual Media from the GUI, the CLI, or the iLO scripting toolkit for many tasks,
including the automation of deployment and provisioning.
•
Control iLO 4 by using a remote management tool.
For more information about iLO 4 features, see the iLO 4 documentation on the Hewlett Packard
Enterprise website (http://www.hpe.com/info/ilo/docs).
The iLO 4 hardware and firmware features and functionality, such as NAND size and embedded user
partition, vary depending on the server model. For a complete list of supported features and functionality,
see the iLO 4 QuickSpecs on the Hewlett Packard Enterprise website
(http://www.hpe.com/info/Quickspecs-iLO).
HPE ProLiant Pre-boot Health Summary
If the server will not start up, you can use iLO to display diagnostic information on an external monitor.
This feature is supported on servers that support external video and have a UID button or an SUV
connector. When power is available to the server but the server is not powered on, iLO runs on auxiliary
power and can take control of the server video adapter to display the HPE ProLiant Pre-boot Health
Summary.
