If AC power has been restored for 30 minutes, and the UPS is not charged completely, check the UPS battery.

Log message: Low Battery.

After StorEdge receives the Low Battery notification from the UPS, this message is logged and the shutdown process is initiated in order to protect customer data.

Log message: Controller write-back cache is enabled.

System AC power and UPS have returned to a reliable state. Write-back cache is enabled.

Log Message: Blower Fan has failed.

This is an indication that one of the StorEdge cooling fans has failed.

Verify that one or more of the following indicators are present:

The unit system status on the front of the StorEdge is a solid red.

The system status light on the back of the StorEdge is a solid red.

The log should have a message “Blower fan # has failed”.

Front panel may have message in display “P11 Fan # has failed”.

The # is number of the fan 1, 2, 3, 4 all four fans are on the fan enclosure assembly located inside the StorEdge unit.

The failed fan # should be lit on the fan assembly.

Contact Technical Support to replace the failed fan.

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.
