Prior to creating a mirror relationship, the Remote Volume Mirroring feature must be enabled and activated on both the primary and secondary storage arrays. The primary volume is the volume that accepts host I/O and stores application data. When you create a remote volume mirror, a mirrored volume pair is created and consists of a primary volume at the primary storage array and a secondary volume at the secondary storage array.

Data from the primary volume is copied in its entirety to the secondary volume. The secondary volume maintains a mirror (or copy) of the data from its associated primary volume. The secondary volume remains unavailable to host applications while mirroring is underway. In the event of a disaster or catastrophic failure of the primary site, the secondary volume can be promoted to a primary role.

For detailed information on this premium feature, refer to the Array Management Window online help or to the SANtricity Storage Manager Remote Volume Mirroring Feature Guide.

Mirror Relationships

A secondary volume must be created on the secondary site if one does not already exist and must be a standard volume of equal or greater capacity than the associated primary volume.

When a secondary volume is available, a mirror relationship can be established in the storage management software by identifying the storage array containing the primary volume and the storage array containing the secondary volume.

Mirror Repository Volumes

A mirror repository volume is a special volume in the storage array created as a resource for the controller owner of the primary volume in a Remote Volume Mirror. The controller stores mirroring information on this volume, including information about remote writes that are not yet complete. The controller can use this information to recover from controller resets and accidental powering-down of storage arrays.

When you activate the Remote Volume Mirroring feature on the storage array, you create two mirror repository volumes, one for each controller in the storage array. An individual mirror repository volume is not needed for each Remote Volume Mirror.

When you create the mirror repository volumes, you specify the location of the volumes. You can either use existing free capacity or you can create a volume group for the volumes from unconfigured capacity and then specify the RAID level.

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.
