Alom, Ilom, & Elom Part I

Introduction:If you are anything like me, and you have not been a knee deep in Sun hardware for the last 10 years of your life, then you probably get pretty confused between the differences between using Sun’s Alom, Ilom, or Elom. It seems every time I start to get familiar with how to manage one type of server, Sun comes up with something new. After a while, which command you should use where becomes an exercise in trial and Error. Hell, if that command does not work here, then try something else. Anyway, here are some notes that I put together to try to keep things straight.

What’s What?


ILOM is the system Service Processor Sun includes with Sun x64 systems.ILOM, can also be accessed via an integrated HTTPS
server, meaning that a user friendly graphical user interface is


This management system is comprised of a system on a chip that includes the following:

  • Service processor (SP)
    -This is the hardware that consists of a dedicated processor that
    communicates through the system serial port. The SP can also
    communicate through an Ethernet port that is shared with the OS
  • Embedded server management software – This is embedded software running on the SP.
  • Command line
    interface (CLI) – The command-line interface is a dedicated software
    application that enables you to operate the SP and associated software
    using keyboard commands. You can use the command-line interface to send
    commands to the SP. You can connect a terminal or emulator directly to
    the system serial port or connect over the Ethernet using a Secure
    Shell (SSH).

  • Web-based interface
    – The web-based interface provides a powerful, yet easy-to-use web
    browser interface that allows you to log in to the SP, and perform
    system management, monitoring, and certain IPMI tasks.
  • Remote Console/Javatrademark Client
    – The Java Client supports the remote console functionality, which
    allows you to access your server’s graphical display remotely across
    the network, as if you were physically located there. It redirects the
    keyboard, mouse, and video screen, and can redirect input and output
    from the local machine’s CD and diskette drives. It can also redirect
    ISO images of the media for these devices; that is, it can create
    virtual devices based on media images.


The ALOM System Controller and ALOM firmware combine the features of RSC and LOM, as well as adding several new features. ALOM can only be run via telnet (insecure), SSH (secure), or a serial
cable, and is therefore limited to the command line interface.
