SunVTS Software and Security

During SunVTS software installation, you must choose between Basic or Sun Enterprise Authentication Mechanism (SEAM) security. Basic security uses a local security file in the SunVTS installation directory to limit the users, groups, and hosts permitted to use SunVTS software. SEAM security is based on Kerberos—the standard network authentication protocol—and provides secure user authentication, data integrity, and privacy for transactions over networks.

If your site uses SEAM security, you must have the SEAM client and server software installed in your networked environment and configured properly in both Solaris and SunVTS software. If your site does not use SEAM security, do not choose the SEAM option during SunVTS software installation.

If you enable the wrong security scheme during installation, or if you improperly configure the security scheme you choose, you may find yourself unable to run SunVTS tests. For more information, see the SunVTS User’s Guide and the instructions accompanying the SEAM software.

Exercising the System Using Hardware Diagnostic Suite

The Sun Management Center product features an optional Hardware Diagnostic Suite, which you can purchase as an add-on. The Hardware Diagnostic Suite is designed to exercise a production system by running tests sequentially.

Sequential testing means the Hardware Diagnostic Suite has a low impact on the system. Unlike SunVTS, which stresses a system by consuming its resources with many parallel tests (see “Exercising the System Using SunVTS Software” on

page 106), the Hardware Diagnostic Suite lets the server run other applications while testing proceeds.

When to Run Hardware Diagnostic Suite

The best use of the Hardware Diagnostic Suite is to disclose a suspected or intermittent problem with a noncritical part on an otherwise functioning machine. Examples might include questionable disk drives or memory modules on a machine that has ample or redundant disk and memory resources.

In cases like these, the Hardware Diagnostic Suite runs unobtrusively until it identifies the source of the problem. The machine under test can be kept in production mode until and unless it must be shut down for repair. If the faulty part is hot-pluggable or hot-swappable, the entire diagnose-and-repair cycle can be completed with minimal impact to system users.

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.
