Are you curious to know what is ILO in server? You have come to the right place as I am going to tell you everything about ILO in server in a very simple explanation. Without further discussion let’s begin to know what is ILO in server?

In the realm of server administration and management, ILO, which stands for Integrated Lights-Out, is a powerful and indispensable feature that empowers system administrators to oversee and control servers remotely. This technology has revolutionized the way servers are managed, making it more efficient and flexible. In this blog, we will explore what ILO in servers is, its significance, how it works, and the benefits it offers to the world of IT infrastructure.

What Is ILO In Server?

ILO, or Integrated Lights-Out, is a proprietary technology developed by Hewlett Packard Enterprise (HPE) and is also commonly referred to as DRAC (Dell Remote Access Controller) in Dell servers or BMC (Baseboard Management Controller) in other systems. ILO is a management interface that provides remote management capabilities for servers and allows administrators to control and monitor server hardware, even when the operating system is offline or unresponsive.

Key Components Of ILO:

  1. Dedicated Management Processor: ILO features a dedicated management processor separate from the server’s primary CPU. This processor is responsible for handling remote management tasks.
  2. Web-Based Interface: ILO is typically accessible through a web-based interface. Administrators can log in using a web browser from anywhere with an internet connection.
  3. Remote Console: One of the primary functionalities of ILO is the remote console, which allows administrators to access and control the server’s desktop as if they were physically present. This is invaluable for troubleshooting and maintenance.
  4. Alerts and Notifications: ILO can monitor server health and send alerts and notifications to administrators in the event of hardware failures, high temperatures, or other critical issues.

How ILO Works:

  1. Dedicated Network Port: ILO has its own network port, separate from the server’s primary network connections. This dedicated port ensures that administrators can access ILO even if the server’s main network interfaces are down.
  2. Secure Authentication: To access ILO, administrators must authenticate with a username and password. This helps ensure security and prevent unauthorized access.
  3. Remote KVM Access: ILO provides remote keyboard, video, and mouse (KVM) access, allowing administrators to interact with the server as if they were physically present. This is particularly useful for server maintenance and troubleshooting.
  4. Virtual Media: ILO enables remote management of virtual media. Administrators can mount ISO images or other media remotely, making tasks like OS installation or firmware updates straightforward.

Significance And Benefits:

  1. Remote Management: ILO eliminates the need for physical proximity to the server. Administrators can manage and troubleshoot servers from anywhere, reducing downtime and operational costs.
  2. Efficiency: ILO streamlines server management, allowing administrators to efficiently diagnose and address issues without the need for on-site visits.
  3. Proactive Monitoring: ILO’s ability to proactively monitor server health and send alerts ensures that administrators can respond quickly to critical hardware or temperature issues.
  4. Security: ILO is designed with security in mind, with features like encryption, strong authentication, and role-based access control.
  5. Cost Savings: The ability to manage servers remotely results in cost savings by reducing travel expenses and minimizing server downtime.


ILO in servers is a game-changer in the world of IT infrastructure management. It empowers administrators to control and monitor servers remotely, improving efficiency, reducing downtime, and enhancing security. With ILO, server management has evolved to meet the demands of modern data centers, ensuring that servers are always accessible and operational, regardless of their physical location. It is a vital tool for any organization that relies on servers for its operations and data processing needs.


How Does ILO Server Work?

ILO makes it possible to perform activities on an HP server from a remote location. The ILO card has a separate network connection (and its own IP address) to which one can connect via HTTPS. Possible options are: Reset the server (in case the server doesn’t respond anymore via the network card)

What Is A ILO?

The International Labor Organization (ILO) is devoted to promoting social justice and internationally recognized human and labour rights, pursuing its founding mission that labour peace is essential to prosperity.

What Is ILO In Dell Server?

If we talk about monitoring and management of servers Hardware, the first names that come to mind are iDRAC (Integrated Dell Remote Access) and ILO (Integrated Lights-Out), both technologies for maintenance of servers “out-of-band”, without dependence on the operating system.

Is ILO Hardware Or Software?

Integrated Lights-Out, or ILO, is a proprietary embedded server management technology by Hewlett-Packard which provides out-of-band management facilities. The ILO software can remotely perform most functions that otherwise require a visit to the servers at the data center, computer room, or remote location.
