iLO

• What is iLO?

iLO stands for Integrated Lights Out Remote Management
Almost all HP ProLiant servers from Generation 2 systems onwards have included the iLO management port as standard.

What does it do?
you can power the server down and watch it reboot, jump in and configure the BIOS should you need to; watch the OS load up (note iLO doesn't require an OS to be already installed)
mount your local desktop USB or DVD to the remote server
You can even have the server boot from an ISO image on the network

The optional iLO Advanced provides key-activated features that enable remote access to system console with full keyboard and mouse control during any server state
iLO Advanced also allows administrators to maintain system firmware or run diagnostics on remote servers from an image on a workstation floppy or CD drive or network web server

Benefits of using iLO.
Reduces travel and operational costs
Automates system support functions
Increases availability
Ensures reliable, efficient access and data security

The remote console performance of iLO 2 is amazing and is the equivalent of KVM over IP console switch performance
