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

(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 (virtual media), depends on license. * Access the server's Integrated Management Log (IML) * Can be manipulated remotely through XML-based Remote Insight Board Command Language (RIBCL) * Full command-line interface support through RS-232 port (shared with system), though the inability to enter function keys prevents certain operations * SSH remote network access to iLO card supporting public key authentication, 1024 bit DSA key, at least since iLO 3 * iLO Federation * Two factor authentication * Remote syslog, depends on license. iLO provides some other utilities virtual power and a remote console. iLO is either embedded on the system board, or available as a PCI card.

Availability

. RIB was replaced with RILOE (Remote Insight Light-Out Edition), which was only available for PCI. The original RILOE was replaced with RILOE II. HP stopped manufacturing RILOE II in 2006. The final firmware version for RILOE is 2.53(A) dated 9 Mar 2004 and for RILOE II is 1.21 dated 5 July 2006. For some older ProLiant 100 series servers there is a "Lights Out 100" option, which has more limited functionality. The LO100 is a traditional IPMI BMC, and does not share hardware or firmware with iLO. Newer ProLiant 100 series servers have a standard iLO. There is also a version of iLO for HP Moonshot systems referred to as iLO Chassis Management which is often abbreviated as iLO CM. The Chassis Management version of iLO was derived from iLO 4. As of June 2018 the most recent Chassis Manager Firmware available is version 1.56 which was released as part of the Moonshot Component Pack 2018.02.0. Although HP included iLO functionality in the ProLiant Gen8 MicroServer, they removed it from the Gen10 version. The ProLiant MicroServer Gen10+ has an iLO add-on card.

Versions

There have been multiple generations of iLO, each generation noted by a single digit number ("iLO 2"). Some generations of iLO are segmented into different editions, based on what features are licensed. iLO includes updatable firmware, for which HP periodically releases new versions.

Programming Interfaces

Several tools or APIs exist for interacting with HP iLO: * Ansible: hponcfg module *

standard developed by the DMTF, which is implemented in iLO 5. It can be managed in an industry standard way, by all Redfish compatible tools. However, since Redfish allows the vendors to add custom functionality to their Redfish API, HPE forked the DMTF's tools and added additional functionality: * ilorest tool * Redfish Python library

Security issues

In December 2021 Iranian researchers at Amnpardaz security firm have discovered rootkits in HPs iLO (Integrated Lights-Out) management modules.
