4.1Installing and Removing Hot-Pluggable SCSI Hard Disk Drives

Note –The server and Hard Disk Drives contain electronic parts that are extremely sensitive to static electricity. Do not touch any metal parts. Wear an antistatic wrist strap.

The Hard Disk Drives are hot-pluggable modules. This means that you do not need to power off the server or remove it from the rack to install or remove the Hard Disk Drives.

However, you do need to make sure that no system or application software is using a Hard Disk Drive when you remove it.

Note –If you intend to remove a Hard Disk Drive with Solaris running, follow the instructions in Appendix A before performing the steps below.

1.Remove the front bezel.

Release the bezel from the server by pressing in on the tabs at either end of the bezel.

2.Pull out the grilles.

3.Do one of the following:

■If you are installing a Hard Disk Drive, slide it into its tray at the front of the server (see FIGURE 4-1). Push it in firmly until the metal lever starts to close: this indicates that it has engaged with the backplane connector. Then, push the metal lever until the disk drive clicks into place.

Note –When inserting a Hard Disk Drive into its enclosure, make sure the top of the drive is touching the top of the enclosure. If you try to install it with the bottom of the drive touching the bottom of the enclosure, the drive will not align with the slide rails inside the enclosure, and you will not be able to insert the disk.

■If you are removing a Hard Disk Drive, locate the latch at the front of the disk and slide it to the right (see FIGURE 4-1). This causes the metal lever to open. Holding the latch, pull the disk part way out of its bay and leave it for a minute to make sure it has stopped spinning. (If a disk is fully removed while it is still spinning, gyroscopic forces can damage its bearings.) When it has stopped spinning, pull it out of the chassis.

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.
