Oracle Integrated Lights Out Manager (ILOM) provides advanced service processor (SP) hardware and software that you can use to manage and monitor your Exalogic machine components, such as compute nodes, gateway switches, storage appliance, and the InfiniBand switch. ILOM's dedicated hardware and software is preinstalled on these components.
ILOM enables you to actively manage and monitor compute nodes in the Exalogic machine independently of the operating system state, providing you with a reliable Lights Out Management (LOM) system.
With ILOM, you can proactively:
Learn about hardware errors and faults as they occur
Remotely control the power state of your compute node
View the graphical and non-graphical consoles for the host
View the current status of sensors and indicators on the system
Determine the hardware configuration of your system
Receive generated alerts about system events in advance via IPMI PETs, SNMP Traps, or E-mail Alerts.
The ILOM service processor (SP) runs its own embedded operating system and has a dedicated Ethernet port, which together provide out-of-band management capability. In addition, you can access ILOM from the compute node's operating system. Using ILOM, you can remotely manage your compute node as if you were using a locally attached keyboard, monitor, and mouse.
ILOM automatically initializes as soon as power is applied to your compute node. It provides a full-featured, browser-based web interface and has an equivalent command-line interface (CLI).
The ILOM management interface is also integrated with Oracle Enterprise Manager Ops Center. Oracle Enterprise Manager Ops Center can discover new and existing systems on your network, update firmware and BIOS configurations, provision the operating environment with off-the-shelf distributions, manage updates and configuration changes, and remotely control key aspects of the service processor such as boot control, power status, and indicator lights.
Exalogic compute nodes are configured at the time of manufacturing to use Sideband Management. This configuration eliminates separate cables for the Service Processor (SP) NET MGT port and the NET0 Port.
ILOM supports following interfaces for accessing its features and functions:
The web interface provides an easy-to-use browser interface that enables you to log in to the SP, then to perform system management and monitoring.
The command-line interface enables you to operate ILOM using keyboard commands and adheres to industry-standard DMTF-style CLI and scripting protocols. ILOM supports SSH v2.0 and v3.0 for secure access to the CLI. Using the CLI, you can reuse existing scripts with Sun systems, and automate tasks using familiar interfaces.
