HP iLO

Integrated Lights-Out, or iLO, is a proprietary embedded server management technology by Hewlett-Packard which provides out-of-band management facilities. The physical connection is an Ethernet port that can be found on most Proliant servers of the 300 and above series.

iLO has similar functionality to the lights out management (LOM) technology offered by other vendors, for example Sun/Oracle’s ILOM, Dell DRAC, the IBM Remote Supervisor Adapter and Cisco CIMC.

 

Features

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 normal network card)
  • Power-up the server (possible to do this from a remote location, even if the server is shut down)
  • Remote console (in some cases however an ‘Advanced license’ may be required for some of the utilities to work)
  • Mount remote physical CD/DVD drive or image
  • Access the server’s IML (Integrated Management Log)
  • Can be manipulated remotely through XML-based Remote Insight Board Command Language (RIBCL)
  • Full CLI support through RS-232 port (shared with system), though the inability to enter Function keys prevents certain operations

iLO provides some other utilities like virtual media (CD, floppy), virtual power and a remote console. iLO is either embedded on the system board, or available as a PCI card.
