If you have a snapshot volume that you no longer need, instead of deleting it, you can reuse it (and its associated repository volume) to create a different point-in-time image of the same base volume. Re-creating a snapshot volume takes less time than creating a new one.

When you re-create a snapshot volume:

■The snapshot volume must have either an optimal or a disabled state.

■All copy-on-write data previously on the snapshot repository volume is deleted.

■Snapshot volume and snapshot repository volume parameters remain the same as the previously disabled snapshot volume and its associated snapshot repository volume. After the snapshot volume is re-created, you can change parameters on the snapshot repository volume through the appropriate menu options.

■The original names for the snapshot volume and snapshot repository volumes will be retained. You can change these names after the re-create option is completed.

Performing Defragment Operations

Using an operating system-specific defragment utility to perform a defragment operation on a base volume with an associated snapshot repository volume will cause a copy-on-write of every data block in the base volume. This can cause the snapshot repository volume to fill before the defragment operation is completed.

As a result, the snapshot volume will fail or host writes will fail to the base volume, depending on the Snapshot Volume Full condition that was originally set for the snapshot volume.

To prevent this from occurring, ensure that the snapshot repository volumes' capacity is set to at least 105% of the size of the base volume before using a defragment utility. This is the minimum size needed to support a copy-on-write of every data block in the base volume, which will occur as a result of a defragment operation.

Dynamic Volume Expansion (DVE)

Caution – Increasing the capacity of a standard volume is only supported on certain operating systems. If volume capacity is increased on a host operating system that is unsupported, the expanded capacity will be unusable, and you cannot restore the original volume capacity. For information on supported operating systems, refer to the SANtricity Storage Manager Product Release Notes shipped with the storage management software.

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.
