8.4Setting Up LOM Privileges for Named Users

You can specify up to four named users of the LOM device on a Sun Fire V120 or Netra 120 server. By default no users are set up and therefore no user login prompt appears when you use the LOM escape sequence.

However, if you set up one or more users, every time you use the LOM escape sequence to display the lom> prompt you will be prompted for a user name and password. Therefore, one of the user accounts you set up, must be for yourself.

Four levels of authorization are available for named users. By default all four levels are open to them. However, if you specify any (using the lom> userperm command), only the level or levels that you specify will be available.

8.4.1Permission Levels Available for LOM Users

The four levels of authorization are:

■Console permission (c-level)

With this level of permission a named user can exit from the lom> prompt to the Solaris prompt (if the Serial A/LOM port is shared between the LOM and the console).

■User administration permission (u-level)

With this level of permission a named user can add and delete users and alter their permission levels.

■Administration permission (a-level)

With this level of permission a named user can change the LOM device’s configuration variables (see Section 8.1, “Introduction to Lights-Out Management” on page 8-2).

■Reset permission (r-level)

With this level of permission a named user can reset the server and power it on and off using the LOM device.

For information about how to assign one or more of these levels of authorization to a named user, see Section 8.4.7, “Specifying Permissions for a Named User” on page 8-16.

V120, 120 specifications

Sun Microsystems' V120 and 120 servers emerged as robust solutions in the early 2000s, catering primarily to small to medium-sized enterprises and branch offices. These servers were built to deliver reliable performance, ease of use, and efficient resource management, making them appealing choices for organizations aiming to balance performance with budgetary constraints.

One of the standout features of the Sun V120 server was its UltraSPARC III processor architecture. This powerful processing capability provided substantial improvements in processing power and energy efficiency, allowing users to run demanding applications and serve multiple users without a hitch. The UltraSPARC III architecture supported a 64-bit computing environment, enabling better memory utilization and rapid execution of high-volume transactions.

In terms of memory, the V120 could accommodate up to 32GB of DDR SDRAM. This significant memory capacity allowed for enhanced performance in data-intensive applications, facilitating smoother multitasking and reduced response times. The server supported dynamic reconfigurability, which meant system resources could be adjusted on-the-fly without shutting down operations, thus ensuring minimal downtime.

Storage solutions on the V120 were flexible and optimized for various requirements. The server offered options for internal hard drives for local storage, as well as configurations that supported external storage systems, providing users with a variety of scalability options. The inclusion of multiple SCSI and IDE interfaces allowed for better integration with existing IT infrastructure.

Networking capabilities in the V120 included integrated Ethernet interfaces, which supported both Fast Ethernet and Gigabit Ethernet options. This ensured seamless connectivity and sufficient bandwidth for network applications, while the server’s compact design made it easy to deploy within existing setups.

As for its operating systems, the V120 was compatible with Solaris, Sun's flagship UNIX-based operating system, which was celebrated for its scalability and reliability. Organizations could also run Linux distributions, further broadening the server's appeal and making it versatile for varied workloads.

Additionally, the V120’s design prioritized energy efficiency, which helped companies reduce operating costs and their environmental footprint. The server’s compact form factor allowed for efficient cooling and reduced space requirements.

In conclusion, the Sun V120 server, alongside the V120 model, represented a marriage of advanced technology, expansive features, and flexible deployment options. It provided businesses with a dependable platform for various applications, establishing itself as a valuable tool for organizations looking to leverage the power of enterprise computing without exorbitant costs.
