array, the amount of time you can afford to keep the command module offline, and the method that most closely matches the upgrade procedure recommended in the storage management software and this guide.

Replace All Drives at the Same Time

If you are upgrading drives containing RAID 0 volumes, you must use this method. This method requires you to back up the command module and turn off the power to the storage array before replacing the drives. After replacing all the drives, you must reconfigure the command module and restore the data from backup media. This is the safest way to exchange drives without losing data. However, this method may take considerable time to complete because of the backup, reconfiguration, and restoration procedures. Also, other users will be unable to use the command module until you finish the procedure. To use this upgrade method, refer to “Replacing All Drives at the Same Time” on page 3-36.

Replace One Drive at a Time

This method works only on drives containing redundant volumes, RAID 1, 3, or 5. If you are upgrading drives containing RAID 0 volumes, you must not use this method. This procedure lets you replace the drives while the command module is in operation, eliminating the necessity to shut down the command module. You manually fail each drive, replace it, and wait for the system to restore data to the new drive before installing the next drive. After installing all of the new drives, you configure them to create additional drive space.

Depending on your configuration, the reconfiguration procedure for this method may require considerable time to complete. Furthermore, you can lose data if the storage array reconfiguration or drive restoration fails. For this reason, you should back up all data on the command module before using this upgrade method. This will safeguard your data if the reconfiguration or restoration fails, or if the new drive malfunctions. To use this upgrade method, refer to “Replacing One Drive at a Time” on page 3-39.

3.3.2Adding New Drives to Empty Slots

Use the following procedure to install additional drives into empty slots in the command module Figure 3-19 on page 3-35illustrates inserting and removing a drive. You can install additional drives while the command module is in operation.

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.
