8.6Separating the LOM From the Console on the Serial A/LOM Port

By default, the LOM device shares the Serial A/LOM port with the console, and when it has an event report to send it takes control of the Serial A/LOM port itself, interrupting any console activity you are performing. To prevent the LOM device from interrupting the console, either turn serial event reporting off (see Section 9.3.4, “Stopping the LOM from Sending Reports to the Serial A/LOM Port (lom -E off)” on page 9-12), or dedicate the Serial A/LOM port to the LOM device and use the Serial B port for console activity (see below).

The advantages of dedicating the Serial A/LOM port to the LOM device and using Serial B as your Console port include:

■Preserving the ability to power on or reset the server (from the lom> prompt on Serial A/LOM) even if for any reason you lose access to Solaris on your console port (Serial B).

■Capturing all LOM events passively on a terminal connected to the dedicated LOM port (Serial A/LOM). Note, however, that if you dedicate the Serial A/LOM port to the LOM device, you cannot use the console command to quit the LOM shell. Instead, for access to Solaris, you must connect to the Sun Fire V120 or Netra 120 server using the Serial B port.

■Preventing a user with console access from using the LOM escape sequence to exit Solaris and access the LOM shell. If you dedicate the Serial B port to the console, users cannot bring up the LOM shell and this means that they cannot interrogate or reconfigure the LOM device.

■Performing binary data transfers. To perform anything other than ASCII transfers, you need to use the Serial B port.

8.6.1Dedicating Serial A/LOM to the LOM

1.Set up console connections to both the Serial A/LOM port and the Serial B port.

2.At the Solaris prompt, type:

#eeprom input-device=ttyb

#eeprom output-device=ttyb

#reboot

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.
