What is ILO Technology (Integrated Lights-Out)?

ILO stands for Integrated Lights-Out. Now, let’s start. What is ILO technology? What is the ILO server, and what is ILO software?

iLO (Integrated Lights-Out) is a proprietary remote server management technology developed by Hewlett Packard Enterprise (HPE) that provides administrators with out-of-band management capabilities.

IT professionals can monitor, control, and troubleshoot servers remotely, eliminating the need for physical presence.

Developed by HPE (Hewlett-Packard Enterprise), ILO comes built into their servers, making it easier to manage even in critical situations.

How Does ILO Technology Work?

ILO Technology works by providing a dedicated interface that allows remote access to the server. Using a web-based dashboard or command-line tools, you can:

Monitor server performance.
Reboot or power on/off the servers.
Update firmware or software.
Troubleshoot issues using virtual media or system logs.

It’s like having full control of your server, no matter where you are.

Features of iLO Technology

HPE’s Integrated Lights-Out (iLO) technology is a powerful server management tool designed to provide remote access, system monitoring, and server maintenance capabilities without needing physical access to the data center.

It is widely used in enterprise IT environments to manage HPE ProLiant servers efficiently. Here is a comprehensive overview of its core features and functionalities:

Mobile Management: The iLO mobile application allows system administrators to manage servers remotely via smartphones or tablets. This feature is particularly useful for offsite IT staff or during emergencies.
Remote Console Access: iLO provides complete remote access to the server’s display, keyboard, and mouse over the network. This functionality allows administrators to manage the server as if they were physically present, even when the operating system is unresponsive or the machine is powered off.
Virtual Media Support: With virtual media, users can remotely mount ISO files, USB drives, or CD/DVD images to the server. This feature is extremely useful for operating system installations, running recovery utilities, or deploying software from remote locations.
Power Management and Control: iLO offers full power control options such as remote power on, shutdown, and reboot. This feature enhances operational efficiency by allowing administrators to perform hardware resets and manage server uptime without being on-site.
Hardware Health Monitoring: iLO continuously monitors the server’s physical components, including CPU usage, memory status, fan speed, temperature, and voltage. It provides real-time alerts and system diagnostics to help prevent hardware failures and reduce downtime.
Security and Access Control: iLO includes robust security measures like role-based access control (RBAC), directory service integration (LDAP/Active Directory), SSL/TLS encryption, and optional two-factor authentication. These features protect server access and ensure compliance with enterprise security policies.
Remote Firmware and BIOS Updates: Administrators can update the server’s BIOS and firmware remotely using the iLO interface. This helps in keeping the systems up to date and secure without requiring physical access to the hardware.
Scripting and Automation Support: For advanced IT automation, iLO supports RESTful APIs, the Redfish API, and the HPE iLO Scripting Toolkit. These tools enable bulk provisioning, configuration, and monitoring in data center environments, making large-scale management more efficient.
Integrated Remote Support: iLO works seamlessly with HPE Insight Remote Support and HPE InfoSight. It can automatically log hardware events, open support tickets, and transmit diagnostics to HPE support, improving incident resolution time.

What is iLO Software and its Benefits

iLO software, also known as HPE Integrated Lights-Out software, is the embedded management software that powers the iLO technology within Hewlett Packard Enterprise (HPE) ProLiant servers.

It provides a browser-based user interface as well as command-line and scripting access to enable complete out-of-band server management.

This software runs on a dedicated management processor embedded in the server’s motherboard, independent of the main server operating system.

Because it operates separately, iLO software allows administrators to access and manage the server even if the operating system is down or the server is powered off.

Core Capabilities of iLO Software

iLO software is designed to deliver intelligent remote management capabilities, and its core functions include:

Remote server access and control
Monitoring server health and performance
Power management (power on/off/reset)
Firmware and BIOS updates
Mounting virtual media
Real-time alerts and diagnostics

Through its intuitive web-based interface, system administrators can view system logs, perform updates, configure hardware settings, and access the server console remotely via HTML5 or Java (in older versions).

The iLO software also provides access to Intelligent Provisioning, which helps in operating system deployment and server setup.

iLO Software Versions and Licensing

iLO software is available in multiple versions, each offering different levels of functionality:

iLO Standard – Comes pre-installed with basic features like system health monitoring, event logs, and power control.
iLO Advanced – A licensed upgrade that unlocks full remote console access, virtual media support, advanced security features, and multi-user collaboration.
iLO Essentials – A more affordable version for small to mid-sized businesses, offering critical remote management features.
iLO Scale-Out – Designed for large-scale, high-density environments such as cloud data centers.

These versions are often managed through HPE’s ecosystem, such as HPE OneView, HPE Insight Remote Support, or HPE InfoSight, for a more centralized and intelligent management experience.

iLO software is a critical component for modern server environments, especially where remote infrastructure management, data center automation, and high availability are priorities.

It allows IT teams to maintain control over server hardware from anywhere in the world, helping organizations minimize downtime and increase operational efficiency.
