About Hot-Pluggable and Hot- Swappable Components

In a Sun Fire V490 system, the FC-AL disk drives are hot-pluggablecomponents and the power supplies are hot-swappable. (No other component of the system is either hot-pluggable or hot-swappable.) Hot-pluggable components are those that you can install or remove while the system is running, without affecting the rest of the system’s capabilities. However, in many cases, you must prepare the operating system prior to the hot-plug event by performing certain system administration tasks. The power supplies require no such preparation and are called hot-swappable components. These components can be removed or inserted at any time without preparing the operating system in advance. While all hot-swappable components are hot-pluggable, not every hot-pluggable component is hot-swappable.

Each component is discussed in more detail in the sections that follow. (Not discussed here are any devices that you may attach to the USB port, which are generally hot-pluggable.)

Caution – The SC card is not a hot-pluggable component. Do not attempt to access any internal components unless you are a qualified service technician. Detailed service instructions can be found in the Sun Fire V490 Server Parts Installation and Removal Guide, which is included on the Sun Fire V490 Documentation CD.

Power Supplies

Sun Fire V490 power supplies are hot-swappable—they can be removed or inserted at any time without prior software preparation. Keep in mind that a power supply is hot-swappable only as long as it is part of a redundant power configuration—a system configured with both power supplies in working condition. (Logically, you cannot “hot-swap” a power supply if it is the only one in the system that still works.)

Unlike other hot-pluggable devices, you can install or remove a power supply while the system is operating at the ok prompt when the blue OK-to-Remove LED is lit.

For additional information, see “About the Power Supplies” on page 38. For instructions on removing or installing power supplies, see the Sun Fire V490 Server Parts Installation and Removal Guide.

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.
