Note –The Sun Fire V120 and Netra 120 servers are supplied with the Solaris operating environment installed and with the supplementary Lights-Out Management (LOM) software described in this chapter and Chapter 9 also installed. This software enables you to manage the server locally or remotely. If you ever need to re-install Solaris and you want to use the Lights-Out Management facilities, you must also

re-install the Lights-Out Management software from the CD entitled Software Supplement for the Solaris Operating Environment. This CD is included with the Solaris media kit. For the location of the LOM packages on the CD, refer to the Solaris Hardware Platform Guide for the release of Solaris that you are using.

8.2Powering On or Resetting the Server From the LOM Shell

To use the Lights-Out Management facilities either remotely or locally, you need a terminal connection to the Serial A/LOM port on the back of the server (see Chapter 6).

There are two ways of interrogating the LOM device or of sending it commands to perform. One is by executing LOM commands from the lom> shell prompt. This chapter tells you how to do this. The other is by executing LOM-specific Solaris commands from the console prompt. For information about the LOM commands available with the Solaris operating environment, see Chapter 9.

When the Sun Fire V120 and Netra 120 servers are connected to a power source, they are always either fully powered or in standby power mode. To remove power entirely from these servers you must disonnect their power cables or open all external circuit breakers. The methods referred to in this chapter for powering the servers on and off by using lom> prompt commands are in fact methods either of powering them on or of returning them to standby power mode. The poweroff command described in this chapter does not power a server off completely.

Note –All commands that involve powering on or off, resetting, or specifying the boot mode of the server require you or the named user to have r-level LOM user permission. If you have not set up any named users of the LOM device, then you (and they) have r-level permission by default. If you have set up one or more named users and you want any of them to use the commands that involve powering on or off, resetting, or specifying the boot-mode of the server, then you must explicitly give those users r-level permission. For more information about user privileges, see Section 8.4, “Setting Up LOM Privileges for Named Users” on page 8-13.

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.
