3.1.2.4Turning Off Power for an Unplanned Shutdown

Storage array modules are designed to run continuously, 24 hours a day. Certain situations, however, may require you to shut down all storage array modules quickly. These situations might include a power failure or emergency because of a fire, a flood, extreme weather conditions, some other hazardous circumstance, or a power supply shutdown caused byoverheating.Use the following procedure to turn off power to all modules in a storage array for an unplanned shutdown. Figure 3-11 on page 3-10shows the locations of the power supply switches.

Caution – Potential damage to drives and data loss. Turning the power off and on without waiting for the disk drives to spin down can damage the drives and may cause data loss. Always let at least 30 seconds elapse from when you turn off the power until you turn it on again.

1.Stop all I/O activity to the command module and attached drives.

2.Remove the front cover from the command module, if applicable.

Caution – Potential data corruption. Turning off the power when an amber fault light is illuminated can cause data corruption. To prevent data corruption, always check for faults and correct all problems before turning off the power.

3.Determine the status of each module and its components.

a.Check the lights on the front and the back of each module.

A green light indicates a normal status; an amber light indicates a hardware fault.

b.Open the Array Management Window for the storage array.

c.To view the status of its components, select the appropriate component button for each module in the Physical View of the Array Management Window.

The status for each component will be either Optimal or Needs Attention.

4.Does each module display green lights only, and is the status Optimal on each module component?

Yes - Go to step 6. No - Go to step 5.

5.Diagnose and correct the fault.

5310 NAS specifications

Sun Microsystems, known for its innovative computing solutions, launched the Sun 5310 Network Attached Storage (NAS) system, which marked a significant advancement in the realm of storage solutions in the early 2000s. The 5310 NAS was designed to provide high-performance, reliable, and scalable storage tailored for enterprise environments.

One of the standout features of the Sun 5310 NAS is its file-serving capabilities, which support multiple protocols, notably NFS (Network File System) and CIFS (Common Internet File System). This dual-protocol support allowed organizations to seamlessly integrate the NAS into diverse IT ecosystems, facilitating interoperability between UNIX, Linux, and Windows systems. The enhanced file-sharing capabilities made it an ideal solution for businesses with mixed operating environments.

The Sun 5310 NAS incorporates cutting-edge technologies to ensure high availability and data integrity. The system utilized a RAID (Redundant Array of Independent Disks) technology, providing various RAID levels to protect against data loss while optimizing performance. Additionally, the device featured hot-swappable drives, enabling maintenance and upgrades with minimal downtime, a crucial factor for business continuity.

Equipped with advanced management software, the Sun 5310 NAS offered users an intuitive interface for monitoring storage health and performance. This software included comprehensive reporting functionalities that allowed IT administrators to oversee usage patterns and capacity planning efficiently.

Scalability was another defining characteristic of the Sun 5310 NAS. The system could easily expand with additional storage modules, accommodating the growing needs of an organization without the necessity for complete system overhauls. This flexibility ensured that businesses could adapt their storage solutions to meet evolving data storage needs without incurring significant costs or disruptions.

In terms of performance, the Sun 5310 NAS featured high I/O throughput achieved through its robust hardware architecture and optimized file serving capabilities. This performance baseline was crucial for organizations that relied on heavy data workloads and required rapid access to information.

In summary, the Sun 5310 NAS from Sun Microsystems embodied a forward-thinking approach to network storage, blending reliability, scalability, and multi-protocol support. Its user-friendly management software, combined with the robustness of RAID technology and hot-swappable drives, made it a preferred choice for enterprises looking to streamline their storage infrastructure while safeguarding critical data.
