Stage Three: The Operating System

If a system passes OpenBoot Diagnostics tests, it normally attempts to boot its multiuser operating system. For most Sun systems, this means the Solaris OS. Once the server is running in multiuser mode, you have recourse to software-based diagnostic tools, like SunVTS and Sun Management Center. These tools can help you with more advanced monitoring, exercising, and fault isolating capabilities.

Note – If you set the auto-bootOpenBoot configuration variable to false, the operating system does not boot automatically following completion of the firmware- based tests.

In addition to the formal tools that run on top of Solaris OS software, there are other resources that you can use when assessing or monitoring the condition of a Sun Fire

V490 server. These include:

■Error and system message log files

■Solaris system information commands

Error and System Message Log Files

Error and other system messages are saved in the file /var/adm/messages. Messages are logged to this file from many sources, including the operating system, the environmental control subsystem, and various software applications.

For information about /var/adm/messages and other sources of system information, refer to your Solaris system administration documentation.

Solaris System Information Commands

Some Solaris commands display data that you can use when assessing the condition of a Sun Fire V490 server. These include the following commands:

■prtconf command

■prtdiag command

■prtfru command

■psrinfo command

■showrev command

This section describes the information these commands give you. For instructions on using these commands, turn to “How to Use Solaris System Information Commands” on page 197, or look up the appropriate man page.

V490 specifications

Sun Microsystems V490 is a robust, high-performance server that was launched in the mid-2000s. It is part of Sun's Enterprise line of servers, specifically designed to meet the needs of businesses requiring reliability, scalability, and efficiency in their computing environments. The V490 is well-regarded for its versatility and ability to handle demanding applications.

At the heart of the V490 is its support for the UltraSPARC IV processor. The server can be configured to contain up to four processors, allowing it to deliver exceptional parallel processing capabilities. The UltraSPARC IV architecture enhances throughput and efficiency, making it suitable for enterprise applications and database management tasks.

One of the standout features of the V490 is its memory capacity. The server can support up to 64 GB of RAM, which allows for extensive caching and improved performance for memory-intensive applications. Coupled with a high bandwidth architecture, the V490 ensures that data can be processed quickly and effectively.

The V490 also emphasizes storage flexibility. It comes equipped with multiple disk drive bays, allowing for a combination of SATA and SAS drives. This flexibility enables businesses to tailor their storage solutions according to their specific performance and redundancy requirements. The V490 supports hot-swappable drives, making maintenance and upgrades considerably easier without taking the server offline.

In terms of connectivity, the Sun V490 features a variety of networking options. It includes multiple Gigabit Ethernet ports, ensuring high-speed data transfer and redundancy. Additionally, the server supports advanced input/output capabilities, making it compatible with various peripherals and external storage solutions.

Sun Microsystems V490 runs on the Solaris operating system, known for its stability and security. This OS enhances the server's performance while providing a reliable platform for mission-critical applications. The V490 also supports virtualization technologies, allowing organizations to run multiple operating systems and applications on a single hardware platform, thus optimizing resource utilization.

Another key characteristic of the V490 is its thermal efficiency. The server is designed with an advanced cooling system that minimizes energy consumption while maximizing performance. This focus on power efficiency aligns with modern data center requirements for sustainability and reduced operational costs.

In summary, the Sun Microsystems V490 is a powerful enterprise server that combines the latest processing technologies, substantial memory and storage capabilities, and robust networking options. Its scalability, along with advanced virtualization support and energy-efficient design, makes it a suitable choice for organizations looking to enhance their IT infrastructure. The V490 remains a testament to Sun Microsystems' commitment to delivering high-quality, reliable computing solutions.
