HPE iLO Guide: What It Is, How It Works & Which License You Need

You do not always need physical access to an HPE server to manage it.

HPE Integrated Lights-Out (iLO) is the embedded remote-management technology used on HPE ProLiant servers. It gives administrators a separate way to monitor server hardware, manage power and perform remote-management tasks even when the operating system is unavailable.

For organisations managing servers in data centres, branch offices or remote locations, this can save a considerable amount of time.

The main licensing question is usually simple:

Is iLO Standard enough, or does your team need iLO Advanced?

What Is HPE iLO?

HPE iLO, or Integrated Lights-Out, is a dedicated management processor built into HPE ProLiant servers.

It operates separately from the main server operating system. This means administrators can still access management functions even when:

• the operating system has crashed
• the server has not yet booted
• the operating system is being installed; or
• normal network access to the OS is unavailable.

This is one of the main advantages of server-class hardware compared with an ordinary PC.

An authorised administrator can use iLO over the management network to check server health, manage power and access other management features supported by the server and its iLO licence.

Businesses comparing current HPE ProLiant servers from Empeller Systems will see different iLO generations depending on the server generation. For example, common Gen10 and Gen10 Plus systems use iLO 5, Gen11 uses iLO 6, and newer Gen12 systems use iLO 7.

What Can You Do With HPE iLO?

The exact feature set depends on the iLO generation, server and licence, but the main functions include the following.

Remote Power Control

Administrators can use iLO to manage server power remotely.

This can include actions such as:

• powering the server on
• powering it off
• restarting it; and
• performing a reset when required.

This is useful when a server becomes unresponsive or requires maintenance and nobody is physically near the machine.

Basic virtual power functionality is part of the standard iLO feature set on supported systems.

Health Monitoring and Alerts

iLO continuously provides information about server hardware.

Depending on the platform, administrators can monitor areas such as:

• temperatures
• cooling fans
• power supplies
• memory
• processors
• storage hardware; and
• general server health.

This gives IT teams an early view of hardware problems without needing to open the server or visit the location.

HPE describes iLO Standard as providing functions for server setup, health monitoring, power and thermal monitoring, and basic remote administration.

Remote Console / Virtual KVM

Remote console access is one of the main reasons businesses consider iLO Advanced.

The Integrated Remote Console allows an administrator to see the server screen and remotely use the keyboard and mouse.

This can be especially useful when:

• the operating system has failed
• the server will not boot normally
• BIOS or UEFI settings need attention
• an administrator needs to watch the boot process; or
• the server is located at another office or data centre.

HPE lists the graphical Integrated Remote Console among the features enabled through iLO licensing, while iLO Advanced specifically includes remote-console functionality.

Virtual Media

Virtual media allows an administrator to present media from another computer to the server remotely.

For example, an administrator may be able to mount an ISO image and use it as if installation media were physically connected to the server.

This can be useful for:

• operating-system installation
• recovery tasks
• loading drivers
• maintenance; and
• troubleshooting.

HPE’s iLO documentation supports remote mounting of local ISO/IMG files and other virtual-media sources where the feature is licensed and supported.

Firmware and Server Management

iLO also forms part of HPE’s wider server-management environment.

Administrators can use iLO and related HPE tools to view firmware information, perform supported updates and manage server components.

The exact process depends on:

• ProLiant generation
• iLO version
• firmware package
• operating environment; and
• HPE management tools being used.

This is one reason businesses should keep iLO firmware updated as part of normal server maintenance.

HPE iLO Versions: iLO 5, iLO 6 and iLO 7

The iLO version normally follows the HPE ProLiant server generation.

A simple guide is:

HPE Server Generation	Typical iLO Version
Gen10	iLO 5
Gen10 Plus	iLO 5
Gen11	iLO 6
Gen12	iLO 7

For example, Empeller’s current HPE range includes Gen10/Gen10 Plus, Gen11 and Gen12 systems, so businesses may encounter all three iLO generations when comparing servers.

The main principle remains similar across generations: iLO provides out-of-band server management, while newer versions add updated management and security capabilities.

If you are also comparing HPE generations, Empeller’s existing guide on HPE Gen10 vs Gen11 servers explains how iLO 5 and iLO 6 fit into the wider platform differences.

HPE iLO License Tiers Explained

The most important distinction for many buyers is between the standard features included with the server and the additional functionality enabled by an iLO licence.

iLO Standard: What Is Included?

HPE states that iLO Standard features are included with every server.

These standard features cover the basic management functions required for server setup and monitoring, including areas such as:

• hardware-health monitoring
• power and thermal monitoring
• basic remote administration
• server setup; and
• standard management access.

This means you should not automatically purchase iLO Advanced simply because you are buying an HPE ProLiant server.

First check:

1. which iLO version the server uses
2. which licence is already installed
3. which management features your IT team actually needs.

For many locally managed servers, the standard feature set may be sufficient.

iLO Advanced: What Does It Add?

HPE iLO Advanced is intended for environments requiring more complete remote administration.

HPE lists advanced functionality such as:

• graphical Integrated Remote Console
• virtual keyboard and mouse
• virtual media
• console collaboration
• console recording and playback
• additional power-management features; and
• other enhanced administrative and security capabilities depending on iLO generation.

For many businesses, the deciding features are remote console and virtual media.

If administrators regularly need to troubleshoot servers remotely, reinstall operating systems or access the server console without visiting the location, iLO Advanced becomes much more valuable.

iLO Standard vs Advanced

Requirement	iLO Standard	iLO Advanced
Hardware-health monitoring	Yes	Yes
Power and thermal monitoring	Yes	Yes
Basic remote administration	Yes	Yes
Virtual power controls	Available on supported systems	Yes
Full graphical remote console	Limited / licence dependent	Yes on supported systems
Virtual media	Advanced/licensed functionality	Yes on supported systems
Console collaboration	No / limited	Available
Console recording	No / limited	Available
Best suited for	Locally accessible or basic server management	Remote sites, data centres and more complete remote administration

Exact features can vary between iLO generations, so HPE’s licensing documentation for the specific server should be checked before purchasing a licence.

How to Check Which iLO License Is Active

Before buying another licence, check what is already installed.

Administrators can log in to the server’s iLO web interface and review the licensing information.

Depending on the iLO generation, the server may show a licence state such as:

• unlicensed/default
• confirmed
• evaluation; or
• another supported licensing state.

For iLO 6, for example, HPE describes the default unlicensed state as providing standard functionality, with a licence required to unlock advanced capabilities.

Checking first can prevent a business from purchasing a licence it already has.

It is also worth checking the exact server quotation. Some servers may have iLO Advanced included or pre-installed as part of the ordered configuration.

Do You Need iLO Advanced?

Not every HPE server needs an Advanced licence.

iLO Standard May Be Enough If:

• the server is located in your office
• IT staff can access it physically when necessary
• you mainly need hardware monitoring
• basic power management is sufficient; and
• remote console and virtual media are rarely required.

For a small business running an HPE ProLiant ML tower server in the same office as its IT team, for example, Standard may cover the main day-to-day requirements.

Empeller’s guide to HPE ProLiant ML tower servers also explains how iLO can help businesses manage ML servers installed in offices and branch locations.

Consider iLO Advanced If:

• servers are located in a remote data centre
• the organisation operates several offices
• administrators frequently manage servers remotely
• physical access is difficult or expensive
• graphical remote console access is important
• virtual media is required for remote installation or recovery; or
• reducing site visits is operationally important.

In these situations, the licence can save far more time than its purchase cost if it avoids unnecessary travel or speeds up recovery during an outage.

Example: When iLO Advanced Can Be Useful

Consider a business in Dubai with an HPE ProLiant rack server installed in a data centre.

The operating system stops responding late at night.

With basic monitoring, an administrator may be able to see that the server is powered on and check hardware health.

With the appropriate iLO Advanced functionality, the administrator can also use the graphical remote console to see what is happening on the server screen and perform supported remote recovery tasks without immediately travelling to the data centre.

The same applies to a company managing servers across Dubai, Abu Dhabi or multiple branch locations.

In this type of environment, remote-management capability is not simply convenient. It can become part of the organisation’s support strategy.

Basic HPE iLO Setup

Accessing iLO for the First Time

Most supported HPE ProLiant servers provide a dedicated iLO management interface.

During initial deployment, the administrator typically:

1. connects the iLO management interface to the management network
2. obtains or configures its IP address
3. accesses the iLO web interface
4. signs in using the server’s supplied or configured credentials; and
5. completes the required network, user and security configuration.

The exact process varies by ProLiant generation, so the server’s installation and iLO documentation should be followed.

iLO Security Best Practices

iLO provides powerful access to the physical server, so it should be protected carefully.

Good practices include:

• changing default or initial credentials
• using strong, unique passwords
• creating individual administrator accounts
• giving users only the privileges they require
• keeping iLO firmware updated
• restricting access to authorised administrators
• separating management traffic from normal user networks
• using firewall or access-control rules
• limiting exposure from the public internet; and
• reviewing logs and alerts.

For larger environments, a dedicated management network or VLAN is generally preferable to placing iLO interfaces directly on the main user network.

iLO should be treated as a privileged management interface, not as another ordinary network device.

HPE iLO and Different ProLiant Servers

iLO is relevant across both HPE tower and rack servers.

For example, Empeller Systems currently lists HPE systems including:

• HPE ProLiant ML30 Gen11
• HPE ProLiant ML110 Gen11
• HPE ProLiant ML350 Gen11
• HPE ProLiant DL360 Gen11
• HPE ProLiant DL380 Gen11
• HPE ProLiant DL385 Gen11
• HPE ProLiant DL380 Gen12

The value of Advanced licensing can differ by deployment.

An ML30 sitting in a nearby office may rarely require full remote console access.

A DL380 running important workloads in a remote rack may benefit much more from advanced remote-management capability.

That is why the licence should follow the deployment and administration requirement, not simply the server price.

Businesses can compare the current HPE server range available from Empeller Systems when planning both the server hardware and required iLO management functionality.

Frequently Asked Questions

Conclusion

HPE iLO provides a dedicated management layer for HPE ProLiant servers.

It allows IT administrators to monitor hardware, manage server power and perform supported administration without relying entirely on the operating system.

For many businesses, iLO Standard is enough for basic hardware monitoring and server management.

iLO Advanced becomes more valuable when administrators need features such as graphical remote console and virtual media, especially when servers are installed in data centres, remote offices or locations that are difficult to access.

Before purchasing an additional licence, check:

Server generation → iLO version → Existing licence → Required features

Do not pay for Advanced simply because it exists.

At the same time, do not avoid it if remote console access could save hours of travel and troubleshooting during a server problem.

For UAE businesses selecting HPE infrastructure, Empeller Systems offers a range of HPE ProLiant servers across tower and rack platforms. The server configuration and iLO licensing can then be selected according to where the server will be installed and how the IT team expects to manage it.
