Dynamic Volume Expansion (DVE) is a modification operation used to increase the capacity of standard or snapshot repository volumes. The increase in capacity can be achieved by using any free capacity available on the volume group of the standard or snapshot repository volume.

Data will be accessible on volume groups, volumes, and disk drives throughout the entire modification operation.

During the modification operation, the volume having its capacity increased shows a status of Operation in Progress, together with its original capacity and the total capacity being added (Figure 3-33). After the increase in capacity is completed, the volumes expanded capacity is displayed, and the final capacity for the Free Capacity node involved will show a reduction in capacity. If all of the free capacity is used to increase the volumes size, then the Free Capacity node involved will be removed from the Logical View.

An increase in storage capacity for snapshot repository volumes would be completed if a warning is received that the snapshot repository volume is in danger of becoming full. Increasing the capacity of a snapshot repository volume does not increase the capacity of the associated snapshot volume. The snapshot volume's capacity is always based on the capacity of the base volume at the time the snapshot volume is created.

Remote Volume Mirroring

This is a premium feature of the storage management software and must be enabled either by you or your storage vendor. The Remote Volume Mirroring feature is used for online, real-time replication of data between storage arrays over a remote distance.

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.
